Airworthiness Directive 2010-17-05
one-timeAirworthiness Directives; The Boeing Company Model 737-600, -700, -700C, -800, and -900 Series Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain Model 737-600, -700, -700C, -800, and -900 series airplanes. This AD requires replacement of the power control relays in the P91 and P92 power distribution panels for the fuel boost and override pumps with new, improved relays having a ground fault interrupter (GFI) feature, or installation and maintenance of universal fault interrupters (UFIs) using a certain supplemental type certificate. This AD results from fuel system reviews conducted by the manufacturer. We are issuing this AD to prevent pump housing burn-through due to electrical arcing, which could create a potential ignition source inside a fuel tank. This condition, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.
Which aircraft AD 2010-17-05 applies to
Applies to airplanes as identified in Boeing Alert Service Bulletin 737-28A1201, Revision 1, dated May 28, 2009 (fuel pump housing burn-through / arcing).
Whether AD 2010-17-05 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.
