PAGE NO. III

DEFINITIONS 1. ‘Alternate procedures are established and used’ or similar statement, means that

alternate procedures (if applicable), to the affected process, must be drawn up by the operator as part of the MEL approval process, so that they have been established before the MEL document has been approved. Such alternate procedures are normally included in the associated operations (O) procedure.

2. ‘Any in excess of those required by regulations’ means that the listed item is required by applicable legislation (e.g. Part OPS, Single European Sky legislation or the applicable airspace requirements) must be operative and only excess items may be inoperative. When the item is not required, it may be inoperative for the time specified by its rectification interval category. Whenever this condition is used in the MMEL, the applicable regulations for the intended flight routes and the resulting dispatch restrictions need to be clarified at the operator’s MEL level.

3. ‘As required by (operational) regulations’ means that the listed item of equipment is subject to certain provisions (restrictive or permissive) expressed in the applicable legislation (e.g. regulation Air Operations, Single European Sky legislation or the applicable airspace requirements). When the equipment is not required, it may be inoperative for the time specified by its rectification interval category.

4. ‘Calendar Day’ means a 24-hour period from midnight to midnight based on either UTC or local time, as selected by the operator. All calendar days are considered to run consecutively.

5. ‘Combustible Material’ means the material which is capable of catching fire and burning. In particular: if a MEL item prohibits loading of combustible (or flammable or inflammable) material, no material may be loaded except the following:

1) Cargo handling equipment (unloaded, empty or with ballast);

2) Fly away kits (excluding e.g. cans of hydraulic fluid, cleaning solvents, batteries, capacitors, chemical generators, etc.); Note: If serviceable tyres are included, they should only be inflated to a minimum pressure that preserves their serviceability; and

3) Inflight service material (return catering — only closed catering trolleys/boxes, no newspapers, no alcohol or duty free goods).

6. ‘Commencement of flight’ is the point when an aircraft begins to move under its own power for the purpose of preparing for take-off.

7. ‘Considered Inoperative’ as used in the dispatch conditions, means that item must be treated for dispatch, taxiing and flight purposes as though it were inoperative. The item shall not be used or operated until the original deferred item is repaired. Additional actions include: documenting the item on the dispatch release (if applicable), placarding, and complying with all remarks, exceptions, and related MMEL provisions, including any (M) and (O) procedures and observing the rectification interval.

DEFINITIONS 8. ‘Daylight’ means the period between the beginning of morning civil twilight and the end of

evening civil twilight relevant to the local aeronautical airspace; or such other period, as may be prescribed by the appropriate authority.

9. ‘Day of discovery’ means the calendar day that a malfunction was recorded in the aircraft maintenance record/log book.

10. ‘Flight’ for the purposes of this MMEL, means the period of time between the moment when an aircraft begins to move under its own power, for the purpose of preparing for take-off, until the moment the aircraft comes to a complete stop on its parking area, after the first landing.

11. ‘Flight Day’, a 24-hour period from midnight to midnight based on either UTC or local time, as selected by the operator, during which at least one flight is initiated for the affected aircraft.

12. ‘Icing Conditions’ means an atmospheric environment that may cause ice to form on the aircraft or in the engine(s) as defined in the POH/AFM.

13. ‘If installed’ means that the item is either optional or is not required to be installed on all aircraft covered by the MMEL.

14. ‘Inoperative’ means that the item does not accomplish its intended purpose or is not consistently functioning within its approved operating limits or tolerances.

15. ‘Is not used’ in the provisions, remarks or exceptions for an MMEL item may specify that another item relieved in the MMEL ‘is not used’. In such cases, crew members should not activate, actuate, or otherwise utilize that item under normal operations. It is not necessary for the operators to accomplish the (M) procedures associated with the item. However, operations-related provisions, (O) procedures must be complied with. An additional placard must be affixed, to the extent practical, adjacent to the control or indicator for the item that is not used to inform crew members that an item is not to be used under normal operations.

16. ‘Intended flight route’ corresponds to any point on the route including diversions to reach alternate aerodromes required to be selected by the operational rules.

17. ‘Item’ means component, instrument, equipment, system or function.

18. ‘(M)’ indicates a requirement for a specific maintenance procedure which must be accomplished prior to operation with the listed item inoperative. Normally these procedures are accomplished by maintenance personnel; however, other personnel may be qualified and authorized to perform certain functions. The satisfactory accomplishment of all maintenance procedures, regardless of who performs them, is the responsibility of the operator. Appropriate procedures are required to be published as part of the Operator’s Manual or MEL.

22. ‘Night” means the period between the end of evening civil twilight and the beginning of morning civil twilight relevant to the local aeronautical airspace; or such other period, as may be prescribed by the appropriate authority. Opposite of ‘Daylight’.

23. ‘Notes’ provide additional information for flight crew or maintenance consideration. Notes are used to identify applicable material which is intended to assist with compliance, but do not relieve the operator of the responsibility for compliance with all applicable requirements. Notes are not a part of the dispatch conditions.

24. ‘Number Installed’ is the number (quantity) of items normally installed in the aircraft. This number represents the aircraft configuration considered in developing this MMEL. Should the number be a variable (e.g. passenger cabin items), or not applicable, a number is not required; a ‘-’ is then inserted. Note: Where the MMEL shows a variable number installed, the MEL should reflect the actual number installed, as far as practical.

25. ‘Number required for dispatch’ is the minimum number (quantity) of items required for operation provided the conditions specified are met. Should the number be a variable (e.g. passenger cabin items) or not applicable, a number is not required; a ‘-’ is then inserted. Note: Where the MMEL shows a variable number required for dispatch, the MEL should reflect the actual number required for dispatch, as far as practical, or an alternate means of configuration control approved by the competent authority.

26. ‘-’ in the Number Installed Column (respectively Number Required for Dispatch Column) indicates a variable number (quantity) of the item installed (respectively item required) or not applicable. Note: Where the MMEL shows a variable number installed, the MEL should reflect the actual number installed, as far as practical.

27. ‘(O)’ indicates a requirement for a specific operational procedure which must be accomplished in planning for and/or operating with the listed item inoperative. Normally these procedures are accomplished by the flight crew; however, other personnel may be qualified and authorized to perform certain functions. The satisfactory accomplishment of all procedures, regardless of who performs them, is the responsibility of the operator. Appropriate procedures are required to be published as a part of the operator’s manual or MEL. Note: The (M) and (O) symbols are required in the operator’s MEL.

PAGE NO. VIII

PREAMBLE Introduction The following is applicable for operators under European air operations regulations (Regulation Air Operations PART- CAT, PART- NCO, and PART-SPO). Paragraph 1.c.2 of Annex I to Article 5 (essential requirements for airworthiness) of Regulation (EC) No 216/2008 (the ‘Basic Regulation’) requires that all equipment installed on an aircraft required for type certification or by operating rules shall be operative. However, paragraph 2.a.3 of Annex IV to Article 8 (essential requirements for air operations) of the Basic Regulation also allows the use of a Minimum Equipment List (MEL) where compliance with certain equipment requirements is not necessary in the interests of safety under all operating conditions. Experience has shown that with the various levels of redundancy designed into aircraft, operation of every system or installed items may not be necessary when the remaining operative equipment can provide an acceptable level of safety. Purpose and limitations This Master Minimum Equipment List (MMEL) is developed by the applicant and holders of (Supplemental) Type Certificate and approved by the European Aviation Safety Agency to improve aircraft use and thereby providing more convenient and economic air transportation for the public. This MMEL includes those items related to airworthiness, air operations, airspace requirements and other items the Agency finds may be inoperative and yet maintain an acceptable level of safety by appropriate conditions and limitations; it does not contain obviously required items such as wings, flaps, and rudders. In order to maintain an acceptable level of safety, the MMEL establishes limitations on the duration of and conditions for operation with inoperative items. Unless specifically allowed by this MMEL, an inoperative item may not be removed from the aircraft. Utilization The MMEL is the basis for the development of individual operator’s MEL which takes into consideration the operator’s particular aircraft equipment configuration and operational conditions. An operator’s MEL may differ in format from the MMEL, but shall not be less restrictive than the MMEL. The individual operator’s MEL, when approved, allows operation of the aircraft with inoperative items of equipment for a certain period of time until rectification can be accomplished. The MEL cannot deviate from Airworthiness Directives, or any other additional mandatory requirements. It is important to remember that all items related to the airworthiness and the operational regulations of the aircraft not listed on the MMEL shall be operative. Suitable conditions and limitations in the form of placards, maintenance procedures, crew operating procedures and other restrictions as prescribed in this MMEL shall be specified in the MEL to ensure that an acceptable level of safety is maintained. It is important that rectifications be accomplished at the earliest opportunity. When an item is discovered to be inoperative, it is reported by making an entry in the continuing airworthiness record system or the operator’s technical log, as applicable. Following sufficient fault identification, the item is then either rectified or deferred following the MEL or other approved means of compliance acceptable to the competent authority and the Agency prior to further operation. MEL conditions and limitations do not relieve the operator from determining that the aircraft is in a condition for safe operation with items inoperative.

PAGE NO. IX

PREAMBLE Prior to operation with any item inoperative acceptance by the crew is required in accordance with the continuing airworthiness management procedures. Operators shall establish a controlled and sound rectification programme including the parts, personnel, facilities, procedures and schedules to ensure timely rectification. Operators should include guidance in the MEL to deal with any failures which occur between the commencement of the flight and the start of the take-off. When developing the MEL, compliance with the stated intent of the preamble, definitions and the conditions and limitations specified in this MMEL is required. Multiple inoperative items Operators are responsible for exercising the necessary operational control to ensure that an acceptable level of safety is maintained. The exposure to additional failures during continued operation with inoperative items shall also be considered. Wherever possible, account has been taken in this MMEL of multiple inoperative items. However, it is unlikely that all possible combinations of this nature have been accounted for. Therefore, when operating with multiple inoperative items, the inter-relationships between those items and the effect on aircraft operation and crew workload shall be considered. Rectification interval extension The operator may be permitted, by its competent authority, to extend the rectification intervals of the MEL. This MMEL has been evaluated taking into account a one-time extension of the rectification intervals of category B, C and D.

GUIDELINES FOR (M) & (O) PROCEDURES The OEB has identified a need for certain procedures to provide an adequate level of safety while providing relief for some items. These procedures must be established by the operator and may be based on the aircraft manufacturer’s recommended procedures, Supplemental Type Certificate modifier’s recommended procedures, or equivalent operator procedures. When recommended procedures are published the operator should comply with these procedures. If recommended procedures are not published, the following guidelines delineate the aspects to be considered by the operator in the development of required procedures. Beechcraft has developed recommended (M) maintenance and (O) operational procedures for the Beechcraft C90 Master Minimum Equipment List (P/N C90BPMEU-00-00, or later revision). Operator’s MEL procedures should be based on the Cessna procedures.
