Airworthiness Directive 2002-24-03
recurringAirworthiness Directives; Boeing Model 747 Series Airplanes Powered by General Electric (GE) CF6-80C2 Series Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747 series airplanes powered by GE CF6-80C2 series engines, that requires repetitive inspections and torque checks to find discrepancies of the fasteners that attach the diagonal brace fittings of the lower spar to the inboard engine struts, and modification of the fasteners if discrepancies are found. This amendment also requires eventual modification of all the fasteners, which ends the repetitive inspections and checks. The actions specified by this AD are intended to find and fix discrepant fasteners of the diagonal brace fittings, which could result in reduced structural integrity of the diagonal brace-to-strut attachment, and possible separation of the strut and engine from the airplane. This action is intended to address the identified unsafe condition.
Which aircraft AD 2002-24-03 applies to
Applies to 747 airplanes with diagonal brace fittings connecting the lower spar to inboard engine struts; repetitive detailed inspection/torque-check schedule differs for airplanes modified per AD 95-13-06 amendment 39-9286 (Group 1) versus not modified (Group 2), per Boeing Alert SB 747-54A2207, dated November 16, 2000, to prevent strut/engine separation.
Whether AD 2002-24-03 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.
