Airworthiness Directive 2010-24-01
one-timeAirworthiness Directives; The Boeing Company Model 737-900ER Series Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for the products listed above. This AD requires doing a one-time general visual inspection for a keyway in two fuel tank access door cutouts, and related investigative and corrective actions if necessary. This AD was prompted by reports of cracks emanating from the keyway of the fuel tank access hole. We are issuing this AD to detect and correct such cracking, which could result in the loss of the lower wing skin load path and consequent structural failure of the wing.
Which aircraft AD 2010-24-01 applies to
Applies to airplanes identified in Boeing Alert Service Bulletin 737-57A1308, Revision 1, dated October 1, 2009.
Whether AD 2010-24-01 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.
