COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Aircraft - General
AD/GENERAL/68
Amdt 4
Cabin Interior Materials 3/92
Applicability: All passenger aeroplanes of 20 seats or more capacity with a Type Certificate in the Transport Category first issued (whether in Australia or elsewhere) on, or after 1 January 1958, which have been manufactured or which have undergone a substantially complete replacement of the cabin interior on, or after 20 August 1988.
Requirement: 1. Except as indicated in notes below, applicable areas of the cabin interior shall comply with FAR 25.853 (c) as effective 20 August 1990.
2. Except as indicated in notes below, applicable areas of the cabin interior shall comply with FAR 25.853 (c) as effective 20 August 1990, except that the total heat release over the first two minutes of sample exposure must not exceed 100 kilowatt
- minutes per square metre and the peak heat release rate must not exceed 100 kilowatts per square metre.
Note 1: Existing items of carry on equipment such as galley stowage units and carts which do not meet the requirement of Para. 1 or 2 above may continue to be used in such applications until expiry of their useful life.
Note 2: Aeroplanes subject to manufacturing delays, unrelated to this requirement, but originally scheduled for completion before the effective compliance dates below, may be accepted with cabin interiors in accord with the standard applicable at the originally scheduled date of manufacture.
Compliance: 1. (a) Before issue of an Australian CofA for all aeroplanes manufactured on, or after 20 August 1990; or
(b) Before further flight for all aeroplanes which have undergone a substantially complete replacement of the cabin interior on, or after 20 August 1990.
2. (a) Before issue of an Australian CofA for all aeroplanes manufactured on, or after 20 August 1988 and before 20 August 1990; or
(b) Before further flight for all aeroplanes which have undergone a substantially complete replacement of the cabin interior on, or after 20 August 1988 and before 20 August 1990.
Background: This Requirement improves the fire resistance of cabin materials and reflects the current FAA requirement as softened by FAR 121.312 to provide a “phasing in” period for the higher standard. This will provide additional time for the development of materials which can be shown to meet the FAR 25.853 (a-1) requirement.
Amendment 2 was raised to maintain parity with Fire Safety Standards in accordance with FAR 25.853 (a-1) amendment No. 25-66 which includes a smoke testing provision. Note 1 was also varied to reflect the FAA position with rotable equipment. Although not currently mandatory it is expected that compliance will be required for such items as galley inserts in the future.
