Airworthiness Directive 2009-22-08
one-timeAirworthiness Directives; Boeing Model 747 Airplanes; and Boeing Model 757-200, -200PF, and -300 Series Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Boeing Model 747 airplanes and certain Boeing Model 757-200, -200PF, and -300 series airplanes. This AD requires replacing the control switches of the forward, aft, and nose cargo doors of Model 747 airplanes; and requires replacing the control switches of cargo doors 1 and 2 of Model 757 series airplanes. This AD results from reports of problems associated with the uncommanded operation of cargo doors. We are issuing this AD to prevent injuries to persons and damage to the airplane and equipment.
Which aircraft AD 2009-22-08 applies to
747 models as identified in Boeing Special Attention Service Bulletin 747-52-2286, dated September 28, 2007; 757 models as identified in Boeing Special Attention Service Bulletin 757-52-0090, dated September 21, 2007.
Whether AD 2009-22-08 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.
