Airworthiness Directive · Amendment 39-15313 · Portable oxygen system
Intertechnique Zodiac Aircraft Systems, Oxygen Reserve Cylinders
This AD applies to Intertechnique (F5341), aluminum alloy AA5283, oxygen cylinders manufactured by Societe Metallurgique de Gerzat SAS with GLD series, GLF series, PC2300 or SLF300 part numbers, installed in any aircraft certificated in any category. These oxygen reserve cylinders are installed on but not limited to Model Airbus 300 series; Pilatus P-6; Dassault Aviation Mystere-Falcon 20, Falcon 50, Falcon 200, and Falcon 900 airplanes; and Eurocopter AS350 and Eurocopter SA315 helicopters.
We are adopting a new airworthiness directive (AD) for certain oxygen reserve cylinders. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country with which we have a bilateral agreement to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, remove any affected oxygen reserve cylinder before further flight.
This AD differs from the MCAI as follows:
(1) The MCAI requires removal of the affected oxygen cylinders at specific time intervals; however, this AD requires removal before further flight.
(2) The MCAI requires certain procedures to be used for emptying the cylinders as well as certain action for cylinders held as spares. These actions are beyond the scope of the action needed to correct this unsafe condition and are not included in this AD.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, Safety Management Group, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Uday Garadi, Aviation Safety Engineer, Regulations and Guidance Group, Fort Worth, Texas 76193-0110, telephone (817) 222-5123, fax (817) 222-5961.
(2) Airworthy Product: Use only FAA-approved corrective actions. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent) if the State of Design has an appropriate bilateral agreement with the United States. You are required to assure the product is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in this AD, under the provisions of the Paperwork Reduction Act, the Office of Management and Budget (OMB) has approved the information collection requirements and has assigned OMB Control Number 2120-0056.
