Airworthiness Directive 2010-06-17
one-timeAirworthiness Directives; The Boeing Company Model 757 Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Model 757 airplanes. This AD requires inspecting to verify the part number of the low-pressure flex-hoses of the flightcrew and supernumerary oxygen system installed under the oxygen mask stowage box at a flightcrew and supernumerary oxygen mask location, and replacing with a new non-conductive low-pressure flex-hose of the oxygen system if necessary. This AD results from reports of a low-pressure flex-hose of a flightcrew oxygen system that burned through due to inadvertent electrical current from a short circuit in an adjacent audio select panel. We are issuing this AD to prevent inadvertent electrical current, which can cause the low-pressure flex-hose of a flightcrew or supernumerary oxygen system to melt or burn, resulting in oxygen system leakage and smoke or fire.
Which aircraft AD 2010-06-17 applies to
Applies to airplanes identified in Boeing Service Bulletin 757-35A0015, Revision 2, dated June 15, 2000 (757-200, -200CB, -200PF) and Boeing Service Bulletin 757-35A0016, Revision 1, dated June 15, 2000 (757-300).
Whether AD 2010-06-17 actually applies to your aircraft (by serial and installed parts) and whether it’s already complied with comes from that aircraft’s records.
How AD compliance is recorded
A valid compliance record (14 CFR 43.9) states:
Tailplate reads a tail number’s logbooks and matches every applicable AD — including this one — to its compliance evidence, with recurring next-due dates computed.
