DESCRIPTION

EU-OPS and PART M:

The EU-OPS and Part M (M.A. 306) specify that an Operator must use an Aircraft Technical Log that has been approved by the Competent Authority when operating an aircraft for Commercial Air Transport use.

Both the EASA and applicable EU-OPS Requirements will be satisfied.

The Aircraft Technical Log is a legal document which is used for:-

o Recording details of ALL maintenance carried out on the particular aircraft between scheduled Base Maintenance visits.

o Recording Maintenance Data and Operating information relevant to Flight Safety for the notice of

the operating crew.

Entries in the Aircraft Technical Log form a permanent part of the Aircraft Records and any irregularities may invalidate the legality of such records.

Only Authorised Personnel may make entries in the Aircraft Technical Log.

AIRCRAFT TECHNICAL LOG ENTRIES

Technical Log Entries shall be:-

• Accurate and as concise and as legible as possible.

• Written using a black/blue ballpoint pen such that the information is transferred to the bottom copy.

AIRCRAFT TECHNICAL LOG ERROR HANDLING

Any errors in the documentation will be handled in the following way:-

• Errors with Text Fields should have a line drawn through the error and initialled. The fields should not be obliterated.

• Errors with Check Boxes should be circled and the correct Check Box marked as

required.

FINAL CERTIFICATE OF RELEASE TO SERVICE

Part M (M.A 306) requires the current Final Certificate of Release to Service (CRS) for the last Scheduled Maintenance Inspection (SMI) to be contained in the Aircraft Technical Log. MOE Chapter 2.16 outlines the CRS procedures to be followed in respect to the TUI Airways Part 145 Organisation. Line Maintenance workpackages are released by a workorder entry. The entry must make reference to the workpackage reference and also quote the aircraft hours and cycles. As long as all taskcards in the workpackage requiring the qualification CAT B2 are signed by appropriate qualified certifying staff, the release to service of the workpackage on the workorder shall be given by a CAT B1 only.

A Single Signatory Final CRS will normally be issued following Hangar Scheduled Base Maintenance. A Base Maintenance Certifying Engineer (BMCE), qualified to Part-66 Category ‘C’ approval will certify and a copy will be placed in the Technical Log.

DEFERRED DEFECT / AIRCRAFT STATUS SHEET

The Deferred Defect / Aircraft Status Sheet is used to provide a record of those Work Orders that have been transferred (deferred) in accordance with the Minimum Equipment List (MEL), Configuration Deviation List (CDL) or other authorizing document. It identifies the Deferral Authority used and details any operational Downgrade which may apply.

Entries in the white blocks are made when a Work Order is initially transferred. Entries in the yellow blocks are made when a Work Order is subsequently closed.

Note 1 When a Sheet is complete, it is to be sent to Aerdata.

Note 2 A periodic cleanup (consolidation) of open entries in the status sheets will be carried out by Line Maintenance to ensure a minimum number of sheets are retained in the log at any time.

The Flight Request will be issued by Maintrol / Engineering and placed in the Technical Log.

The Pilots will then carry out the request at next opportunity and respond as per the recording instruction. This will normally be through raising a Work order at the end of the flight sector.

HIGH FREQUENCY REPEAT INSPECTIONS

Occasionally Repeat Inspections may be required with a frequency that:-

• May not coincide with planned Scheduled Inspection. • Is specific to a limited number of aircraft in the fleet.

Such Repeat Inspections would likely be generated for transferred (deferred) defects.

Control Process

When a requirement for a Repeat Inspection occurs a Work Order will be generated by Maintenance, detailing the problem and all inspection / termination requirements. It must clearly stipulate all the inspection constraints and termination requirements within the Action Taken Block on the Work Order.

• Line Engineers should inform TUI Maintrol as soon as the requirement

is identified, and before aircraft is released to service. • Hangar Engineers should inform short term planning as soon as the requirement

is identified and before aircraft is released to service.

The Work Order will then be transferred with a due date no later than the OCM termination date but clearly state the internal. In addition to the Transferal, an Aircraft Status Sheet will also be raised when:

• The Repeat Inspection falls with 7 days (Hangar Check) OR • Is triggered by the Line Engineers.

Originating Documents

Description

Detailed Instruction

Recording Instruction



Upon entry into AMOS, this Repeat Inspection requirement will be noted and the Production Engineering Department will convert it to a TRACE, it can then be monitored for compliance through AMOS.

The Production Engineering Department will then issue instruction to Maintrol to close down the Transferred Work Order and Aircraft Status Sheet with reference to the amended control process now in place.

Sign-off Process

When a repeat inspection is carried out, it will be certified using a new Work Order from the Aircraft Technical Log (if the work was performed between scheduled maintenance) or an AMOS generated Work Order if the work was completed during Scheduled Maintenance). This Work Order will then be closed with reference back to the originating TRACE / Single Running Task Card.

Once the Task has been carried out, Central Data Entry (CDE) Team will report back its compliance within the AMOS system so that AMOS re-forecasts correctly.

SPECIAL CERTIFICATION SCENARIOS

AUTOLAND DOWNGRADES

If a defect arises that affects the Autoland System, the defect may require multiple resources and skills to resolve it. Following initial investigation, any corrective action may involve multiple function checks and will always need to be verified by an Autoland System Test.

This Autoland System Test must be carried out by an appropriately authorised Engineer.

If the defect Investigation / Rectification / Function Tests and subsequent Autoland System Testing / Re-certification cannot be achieved prior to next flight, a separate work order needs to be generated and transferred for each of the outstanding requirements.

Example

Work Order 1 - Investigate / Repair / Function Test the faulty component. Work Order 2 - Test / Re-certify the Autoland System.

In above example, both Work Orders would be transferred in accordance with the same MEL limitations and both must be resolved before the aircraft is re-certified to full Autoland capability.

PILOT DEFERRALS

If the pilot is required to transfer (defer) a defect down-route, or at an unmanned Maintenance Base, the following process will apply:

1. The Pilot raises the defect Work Order and defect description as per normal Procedure #. 2. The Pilot will write in the Action taken block “Defect transferred to the Aircraft Status Sheet in

ac cordance with the MEL”, and then he will sign and date it just below this text. 3. The Pilot will complete the Transfer Section of the Work Order with deferral details, time limits

etc, but DOES NOT sign the CRS block. 4. The Pilot will raise the next available Aircraft Status Sheet Record and copy the Work Order

Transfer block information into it.



5. The Pilot will remove and hand the middle (yellow) copy of the Work Order to the Handling Agent along with the middle (yellow) copy of the Flight Log.

6. The Pilot will inform Maintrol of these actions as soon as possible so that Maintrol are aware of the Aircraft Status.

At the next visit to the aircraft by a TUI Authorised Engineer:

1. The Authorised Engineer will review Aircraft Technical Log Status Sheets and Work Orders. 2. For any Pilot transferred Work Orders, the appropriately Authorised Engineer will verify that all

required fields are completed correctly (including ATA references, downgrade information, due dates etc.) on both the originating Work Order and the Aircraft Status Sheet.

3. The Authorised Engineer will then remove the following sheets and will either update AMOS, or pass them to CDE for entry.

4. The Authorised Engineer will email / route to AERDATA for uploading into STREAM and for records storage:

a. The top (white) copy of the originating Work Order b. The top (white) copies of any used Flight Log Sheets.

AIRCRAFT OPERATOR DETAILS & MAINTENANCE CONTACT DETAILS

The Operators details on this sheet are required by Part M (M.A. 306), to be contained within the Aircraft Technical log.

It will include the address and contact numbers of TUI Maintenance Control (Maintrol) at Luton.

These phone numbers are for any Maintenance carried out while an aircraft is away from base, and the address to where the relevant pages from the Technical Log are to be sent.

The Reference Form Number: ENG/1294 - Aircraft Operator Maintenance Control Contact Details.



INDEX OF DOCUMENTS

The Reference Form Numbers:

ENG/1525 – Index and Instructions for the Use of Documents in the Technical Log – All Fleets.

DENT & BUCKLE CHART

Each Aircraft Technical Log Contains a set of Dent and Buckle Charts and Damage Summary Sheets. The purpose of these charts is to maintain a record of all allowable damage (dents, buckles, scores etc) until they are rectified by component replacement or permanent repair.

The charts are designed to show:-

• Upper and lower surfaces – Stabilizer and Wings.

• Winglets (As Applicable)

• Left and Right sides – Fuselage.

• Engine fan blade layout.



• Left and Right Engine Nacelles

• Flight deck windscreens.

• RVSM Pitot & Static ports inspection area.

• High damage areas

o Cargo Doors o Aft Fuselage

Dent & Buckle (D&B) Procedure

Each Pre-flight Inspection will include a visual check for skin damage. All new damage found is to be assessed prior to aircraft departure using the Structural Repair Manual (SRM) and/or the Engine Maintenance Manual.

All allowable damage is to marked IAW the Dent and Buckle Chart page 1, then certified by an appropriately authorised Engineer.

The Certifying Engineer must also record the damage information on:

• The next available Work Order – this being the official Maintenance Release Certification.

• The appropriate Dent and Buckle Chart – this is for Pilot/Engineer awareness

and verification that the damage has been assessed as allowable by the designated Certifying Engineer.

• The Damage Summary Sheet – this provides Pilots/Engineers with more detailed

summary to verify it is that actual damage being viewed. It also logs originating Work Order and the identification of the Certifying Engineer.

• A separate Damage Assessment form (ENG/1037). This details exact

damage details and structural location in a consistent format.

The completed Form ENG/1037 is to be forwarded (Fax or Email) with the White copy of Tech Log Work Order to Central Data Entry Team at Luton where, upon receipt, the information will be loaded directly into AMOS, and form part of the aircrafts electronic records.

Note: Form ENG/1037 is available from Maintrol or the TUI Engineering Network. This Form includes check boxes to log any damage in a consistent format for inclusion into the A/C records.

Note: Mechanics with Write Access to AMOS can load the data directly into the Structural Damage tab in the View/Edit Workorder screen (APN 2) instead of raising an ENG/1037.

Dent & Buckle Drawings

Three types of drawings are currently in use: The diagram below shows a typical example of a Dent and Buckle Chart used by TUI



The diagram below shows a typical example of a Structural Damages Summary Sheet.



Special Note: REDUCED VERTICAL SEPARATION MINIMUM (RVSM) CRITICAL AREAS

When visual inspections are being carried out, particular attention is required around the Pitot Probes, Static Ports and Angle of Attack vanes as these are classed as critical areas for Reduced Vertical Separation Minima (RVSM).

ALL damage in RVSM Areas, even if within SRM limits, must be reported to Maintrol.

All damage will be re-appraised during major maintenance for permanent repair. A new Dent and Buckle chart will be issued at the end of the major check.

RECORDING OF ALLOWABLE DAMAGE

When recording allowable damage the emphasis should be on accuracy and detail as this forms part of the aircraft damage records.

Work Order / ATA / Issue Date Provides clear reference to the originating event where the damage was found.

References / Type What manuals / documentation was used to permit the damage

Damage Type / Nature Type Damage Types incl Dent, Delamination, score Nature Types Incl Impact Damage, Leak, Spill, Environmental

Flight Log - Pre-Flight Section:

The Pre-Flight Section is used to record the departure state of the fuel quantity / distribution and anti- icing/de-icing

Fuel Details Block

Pre-refuel Total - enter the amount of fuel on board aircraft prior to commencing the refuel.

- Note: this may not agree with the inbound Commanders fuel remaining value due to fuel burn during APU and/or engine runs.

Uplift - enter the amount of fuel uplifted into the aircraft.

Departure 1 - this value refers to the fuel contents after the initial uplift, which may occur

at any point during the found phase.

Adjust +/- and Departure 2 - these values are for last minute fuel uplifts immediately before departure, if

requested.



Fuel Uplift Calculation Block

Row 1 is for Normal (initial) Refuel readings. Row 2 is for the Adjustment Refuel readings.

To convert fuel from kilograms to Litres:

Uplift in LITRES = Uplift in KG / SPECIFIC GRAVITY (SG) OF FUEL

To convert fuel from kilograms to US gallons:

Uplift in US GALLONS = Uplift in KG / 3

Example for calculating Uplift

Total Prefuel = 8,000kg

Total Uplift = 10,200kg

Total fuel on board = 18,200kg

Uplift in LITRES = Uplift in KG / SPECIFIC GRAVITY (SG) OF FUEL

= 10,200 / 0.8

= 12,750 Litres

Note: Use actual fuel SG provided by the Fuel Tanker driver.

Uplift in US Gallons = 10,200 / 3

= 3,400 US Gallons



Flight Log - The Fuelling Signature

The signature on the Fuelling Certificate identifies the person who supervised the refuel. If a second refuel is needed for top-up purposes, this will be signed for by the Commander on the Commanders Acceptance Certificate.

The person supervising the refuel should sign/date this block.

If supervised by the Pilot - they should quote their rank and signature.

If supervised by an Engineer - they should be appropriately Authorised and use their company

stamp and signature.

Flight Log - Pre-Flight Signature Block

The person who carried out the Pre-Flight Inspection should sign/date this block.

If performed by the Pilot - they should quote their rank and signature.

If performed by an Engineer - they should be appropriately authorised and use their company stamp and signature.

Anti / De-icing Block

When used, the Anti / De-icing block is to be used to record : Fluid application start time, The type of fluid and the mix ratio used.

Two blocks are provided, one for the initial fluid application and one for the second application (if required).

The acceptance of each application is by the signature on the De-icing Form supplied by the De-Icing Company. One form per application is required and is retained by the Pilot in command.



Commanders Acceptance Block

Commander - Commanders Name

Signature - Commanders Signature

When the Pilot signs/dates this block, he/she is signing for the final acceptance of the aircraft. It should only be signed/dated when:

• All current Flight Log blocks have been completed and signed for.

• The A/C Status section at the front of the Technical Log has been reviewed and current

operational status established.

• Anti / De-Icing Blocks have been completed (if applicable) and de-icing is to the commanders acceptance

Who is raising the Work Order. • Pilots can use their operations 3 letter code (3LC) or name • TOM Engineers should use their AMOS Login ID.

This is used to categorise the Work Order for System Reliability Analysis., this analysis is used within Engineering and Maintenance Department to verify performance of the Aircraft Maintenance Program (AMP) as required by both the aircraft operator and the Regulatory Authority.

Pilot Report - should ALWAYS be ticked by the Pilot if the defect is noted during the last

flight sector.

Maint Report - should be ticked by the Engineer if the defect is noted during the current ground phase.

Scheduled - should be ticked by Engineers if the work scope performed was requested by

the Planning Department / Maintrol or if the work scope is a Troubleshooting / Rectification step for a previously Transferred (Deferred) Work Order.

Form ENG/1461 4 digit ATA codes should be used to ensure the correct ATA code is added to this field.

This field is used within the AMOS system to compile Reliability Statistics/ Trends and Repetitive Defects analysis for the aircraft systems by fleet and registration.

It may be different from the actual ATA of the defect; this should be entered in the Action Taken field.”

- This is the Work order number and it’s pre-printed.

Originating Task Linking If the work scope was driven by another task, that task can be referenced here.

- enter the code to reflect the originating Document type here.

• F= Flight Log Number. • W = another Work Order Number. • T = a scheduled Task Card. • C = Quality Assurance concession • D = any other document.

- enter the linked document identification unique number here: • Work Order Number • Task Card ID • Concession Number • Flight Log Number

THE DEFECT/WORK REQUEST AREA

Defect Description / Work Required Block

This is the description of the Defect / Flight Deck Effect or Planning Work Request.

It is MANDATORY that only 1 defect be referenced in any Work Order.

With exception of Pilot Deferral at Non-Maintenance Bases, everything below this Line is MAINTENANCE ONLY.

Action Taken Block

Description of ‘What action has been taken’ to enable the aircraft to fly, and who by.

Many defects require complex maintenance actions to resolve and may involve more than one person.

The Action Taken Block permits controlled staging of the maintenance activity, such that each step can be certified and inspected separately.

If the Action Taken block is filled up, there may be requirement to carry on with the work steps on a Continuation Sheet. These are not part of the Aircraft Technical Log, but if any are used they should be referenced here.

Enter in this column the details of the person performing the work.

Enter in this column the details of the person inspecting the work.

TUI Engineers should use their Company Stamp. Non-TUI Engineers should use their name and Authority Number.



For Pilot Deferrals, the Pilot will clearly state that the defect is transferred to Aircraft Status Sheet, in the Action Taken Block. He/she will then sign and date the Action Taken Block below this statement.

Work Order Closure Fields The work order is considered OPEN and the aircraft is not clear to fly unless these fields are certified

- Enter the current date here.

- Enter the current time as HH:MM here

- Enter the current airport 3 Letter Code (3LC) here

- Enter the Maintenance Organisation number

- Enter the Certifiers’ signature

- Enter here the details of the person inspecting the work. TUI Engineers should use their Company Stamp. Non-TUI Engineers should use their name and Authority Number

Work Order Transfer/Deferral Block

This block is used if the defect has been given the proper authority for transferal, and must be completed by the person carrying out the Transfer (Pilot or Engineer).

It is important to correctly annotate the Downgrades section if an operational downgrade results from this work order transfer.

- Enter the date the defect is being transferred here.

+36

The Originator must now choose one or more of the following three options:

- Enter the date by which the defect needs to be rectified (Calendar days). This is usually linked to the MEL Category and Transfer Date.

Note:

- Enter the number of aircraft hours by which the defect needs to be rectified e.g. 36 will indicate 36 hours limitation (this means that the originator does not need to calculate the actual total aircraft hours the actual total aircraft hours).

- Enter the number of aircraft cycles by which the defect needs to be rectified e.g. +6 will indicate 6 cycles limitation (this means that the originator does not need to calculate the actual total aircraft cycles.

The MEL may quote a combination of Due Date/Due Hours/Due Cycles, in which case, any or all of the boxes may need to be annotated. AMOS will link actual aircraft hours and cycles to the defect when the Work Order is loaded into the Engineering and Maintenance system and this will be monitored / controlled by Maintenance.

To accurately identify due hours or cycles remaining, either;

• Manually count Hours / Cycles flown from Work Order & Flight Log Audit. • Refer to AMOS. • Refer to Maintrol.

For MEL Deferrals - Enter the Minimum Equipment List (MEL) Reference (Inc. NEF Reference) and

Category here. If a box is ticked in error, circle the error and tick the correct box.

- Enter the MEL category (A, B, C, D or NEF as applicable)

For Non MEL Deferrals

- Enter the (CDL/Structural Repair Manual (SRM/Concession #) Reference as an alternate approval authority. For Quality Assurance concession, quote the Concession and record the Concession Number in the Docs references Block at the top of the form. (Doc Type=’C’).

For ALL Deferrals Reason - Enter why the defect is being transferred here ie

- Parts, Time.

If an operational downgrade results from the transfer, tick in the relevant box that indicates the affected category.

If a box is ticked in error, circle the error and tick the correct box. Note: In addition to reproducing this info on the ADD/ASS sheet, this downgrade Information is loaded into the engineering AMOS system to feed System Reliability Monitoring screens. (Defect History, Aircraft Downgrades and Trends are monitored through this)

Special Note Re NEF (Non-Essential Equipment & Furnishings) Deferrals

Non-Essential Equipment & Furnishings include Non-Airworthiness items & installations that have no effect on the aircrafts airworthiness or its ability to operate safely under all operational conditions.

Such Items may include, but are not limited to cosmetic trim, exterior paint, non-mandatory decals / placards that are serviceable but show evidence of being worn / soiled.

Their installations will include, but are not limited to,

• The passenger cabin • Flight deck • Service bays • Electronic equipment centres • Crew rest areas • Toilets • Galley

NEF items are mentioned in the MEL under MEL (B737-800 25-10, B757 / B767 25-20-1, B787 25-00-01) but due to their nature cannot be referenced directly and no MEL repair interval is defined. Instead, such items may be given dispatch relief with reference to the TUI NEF Policy and its supporting Procedure LIN002a.

• NEF Items can initially be deferred with a repair interval of 30 days. • If the defect cannot be rectified for operational based reasons, the Maintrol

Defect Co-ordinator can authorise extension of the repair interval for a period up to, but not exceeding 90 days (120 days total)

• Subsequent extensions can only be authorised by Airworthiness by submission of an AMOS Tech Assist in accordance with GEN 1010 - Rectification Interval Extension (RIE) procedure.

For Tech Log Work Order NEF Deferrals, use the following format / data:
