Requirement

The Type IVA FDR is mandated by ICAO Annex 6 Part III

Section II

Helicopters with a maximum certificated take-off weight in

excess of 3180 (3175) kg

With the first individual certificate of airworthiness issued after

1stJanuary 2005

The Type IVA FDR can capture an increased range of

data derived from the most recent developments in

helicopter technology and avionics with up to 47parameters being recorded

JAR-OPS 3 does not yet cover this requirement

Slide 4OST 07-1

Background

After the completion of the approval process of NPA

OPS-25, the OST tasked the Flight Recorder Study

Group (FRSG) to introduce the new ICAO flight

recorders standards for helicopters into JAR-OPS 3

This was conducted and WP FRSG 03-04 was produced

WP not progressed

OST Action 06-2/23 tasked HSST with EQSG

Significant updating completed by HSST with

agreement of EQSG to produce WP-06/03.7

Considerable liaison with ICAO FLIRECP conducted

Slide 5OST 07-1

Draft NPA

Proposal to amend JAR-OPS 3 to align with

ICAO Annex 6 Part III Section II in requiring an

enhanced level of parameters to be recordedby FDRs and also to incorporate consequential

changes. This will require the fitment of a FDR

with at least Type IVA capabilities.

Harmonisation

The proposal will bring JAR-OPS 3 in line with

FAR Part 135 and ICAO Annex 6

Slide 7OST 07-1

Proposal

Introduction of a new requirement (3.712) and

associated Appendix and ACJ

Significant number of consequential changes to

both Section 1 and 2 and corrections followingprevious amendments

Main Amendment

JAR-OPS 3.712 Flight Data Recor ders

1(See Ap pend ix 1 to JAR-OPS 3.712)

(See ACJ OPS 3.712)

(a) An o perator shal l no t operate a hel icop ter f irst issued with an individ ual

Certi f icate of Airworthin ess on o r after 1s tJanuary 2010 whic h has a

maximum cert i f icated take-off mass o ver 3175 kg unless it is equip ped with a

f l ight data record er that uses a digi tal method o f reco rding and stor in g dataand a method of readi ly ret r iev ing that data from the storage medium is

available.

(b) The f l igh t data recorder shal l be capable of retaining the data recorded

du r ing at least the last 10 hours of i ts operat ion.

(c) The f l ight data recorder must, with reference to a timescale, record:(1) The parameters lis ted in Table A of App end ix 1 to JAR-OPS 3.712

(2) An y dedicated parameters relat ing to novel or uniqu e design o r

operat ional character ist ics o f the hel icop ter as determ ined by the Au tho r i ty

dur ing type or s upp lementa l type cert i f icat ion.

Options

Option 1. - Do nothing.

This would result in the loss of the safety benefits

accruing from the superior range of flight data

parameters available from the Type IVA FDR, over theType IV or Type V FDR

JAA Member States would not be in compliance with

ICAO and would have to file a difference


10/15

Slide 10OST 07-1

Options

Option 2. - To mandate the recording of the

enlarged range of flight data parameters

necessitating the fitting of Type IVA FDRs

according to the timetable specified by ICAOAnnex 6 Part III Section II.

This course of action would avoid the unsatisfactory

effects of Option 1, but would, inevitably, involve the

operators of existing aircraft in the considerable expense

involved in upgrading from the current requirement of a

Type IV or Type V recorder


11/15

Slide 11OST 07-1

Options

Option 3. - To mandate the recording of the enlarged range

of flight data parameters necessitating the fitting of Type IVA

FDRs to affected helicopters first issued with an individual

CofA on or after 1 January 2010 and, thereby, avoid retro-

fitment to existing aircraft.

This would result in the avoidance of significant expense for

operators of existing aircraft, whilst mandating the fitting of

Type IVA FDRs to all affected new aircraft. However, helicopters

first issued with a Certificate of Airworthiness between 1 Jan 05

and the proposed JAR-OPS 3 implementation date of 1 Jan 10

would not be ICAO compliant and, consequently, JAA memberstates would require to file a difference with ICAO.

This is the preferred Option


12/15

Slide 12OST 07-1

Impacts

Helicopter operators purchasing affected new

aircraft

They would be spared the high costs of retro-fitting

existing fleets

Helicopter manufacturers would be affected by

having to install Type IVA FDRs during the

manufacture of all affected new aircraft

Economic effect likely to be neutral

Accident Investigation

Likely improvements in identification of cause

Slide 13OST 07-1

Consultation

Considerable consultation was conducted by the

FRSG/ HSST / EQSG in drafting this NPA including

liaison with representatives of the FLIRECP

The primary consultation prior to the adoption of the

JAR will be through the NPA process. (JAR 11.065).


14/15

Slide 14OST 07-1

Summary and Final Assessment

The proposed changes to JAR-OPS 3 will ensure

alignment with the ICAO Annex 6

The retro-fitting of helicopters first issued with Cs

of A after 1st

January 2005 (Annex 6) would belargely impracticable and would involve

unreasonable expense

The preferred option is to mandate the fitting of

Type IVA FDRs in helicopters first issued with anindividual Certificate of Airworthiness on or after

1stJanuary 2010
