Airworthiness Directive · Amendment 39-14213 · McDonnell Douglas Model 717-200 Airplanes
McDonnell Douglas Model 717-200 Airplanes
This AD applies to McDonnell Douglas Model 717-200 airplanes, certificated in any category, as identified in Boeing Alert Service Bulletin 717-35A0003, Revision 1, dated June 7, 2005.
The FAA is adopting a new airworthiness directive (AD) for certain McDonnell Douglas Model 717-200 airplanes. This AD requires repetitively replacing and testing a certain relay in the passenger oxygen release system in the forward cabin. This AD results from reports of a failed relay in the passenger oxygen release system. We are issuing this AD to prevent failure of the relay, which could result in the oxygen masks failing to deploy and deliver oxygen to the passengers in the event of a rapid decompression or cabin depressurization.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Replace the relay in the passenger oxygen release system in the forward cabin with a new relay and test for proper operation by doing all the actions as specified in the Accomplishment Instructions of Boeing Alert Service Bulletin 717-35A0003, Revision 1, dated June 7, 2005; at the applicable time specified in paragraph (f)(1) or (f)(2) of this AD. Repeat the actions at intervals not to exceed 3,100 flight cycles.
(1) For Group 1 airplanes, as identified in the service bulletin: Within 6 months after the effective date of this AD.
(2) For Group 2 airplanes, as identified in the service bulletin: Before the accumulation of 3,100 total flight cycles, or within 6 months after the effective date of this AD, whichever is later.
Replacements and tests accomplished before the effective date of this AD in accordance with Boeing Alert Service Bulletin 717-35A0003, dated November 19, 2004, are acceptable for compliance with paragraph (f) of this AD.
