Airworthiness Directive 2002-07-07
recurringAirworthiness Directives; Boeing Model 777-200 Series Airplanes Equipped With General Electric GE90 Series Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 777-200 series airplanes equipped with General Electric GE90 series engines. This action requires repetitive inspections of the diagonal brace and forward seals of the aft fairing of the strut to find discrepancies, and corrective actions, if necessary. This action is necessary to prevent primary engine exhaust from entering the aft fairing of the strut and elevating the temperature, which could lead to heat damage of the seals and diagonal brace. Such damage could result in cracking and fracture of the forward attachment point of the diagonal brace, loss of the diagonal brace load path, and consequent separation of the strut and engine from the airplane. This action is intended to address the identified unsafe condition.
Which aircraft AD 2002-07-07 applies to
Boilerplate applicability only; specific 777 serial/line-number list precedes this excerpt and is not included. Requires repetitive detailed inspections (every 500/1,000 flight hours) of the diagonal brace and forward seals of the engine strut aft fairing per Boeing ASB 777-54A0017 (Dec 21, 2001), with conductivity-based corrective actions (repair or replacement) if heat damage is found, to prevent separation of the strut/engine from the airplane.
Whether AD 2002-07-07 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.
