Airworthiness Directive 2017-26-07
recurringAirworthiness Directives; The Boeing Company Airplanes
What this AD requires
We are adopting a new airworthiness directive (AD) for certain The Boeing Company Model 757-200, -200CB, and -300 series airplanes. This AD was prompted by a report of fatigue cracking found in a certain fuselage frame web. This AD requires inspection of the fuselage frame for existing repairs, repetitive inspections of the frame, and applicable repairs. We are issuing this AD to address the unsafe condition on these products.
Which aircraft AD 2017-26-07 applies to
Applicability as identified in Boeing Alert Service Bulletin 757-53A0100, Revision 1, dated September 14, 2017. Installation of STC ST01518SE does not affect applicability; a change-in-product AMOC is not necessary for airplanes with STC ST01518SE installed.
Whether AD 2017-26-07 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.
