Airworthiness Directive 2006-26-06
recurringAirworthiness Directives; Boeing Model 777-200 and -300 Series Airplanes Equipped with Rolls-Royce Engines
What this AD requires
The FAA is adopting a new airworthiness directive (AD) for certain Boeing Model 777-200 and -300 series airplanes equipped with Rolls-Royce engines. This AD requires repetitive inspections to detect cracks of the outer V-blades of the thrust reverser, and corrective action if necessary. This AD also provides for optional terminating action for the repetitive inspections. This AD results from reports of cracked outer V-blades in the thrust reversers. We are issuing this AD to prevent separation of a thrust reverser from the airplane during normal reverse thrust or during a refused takeoff, which could result in impact damage to other airplane areas. If a thrust reverser separates from the airplane during a refused takeoff, the engine could produce forward thrust, resulting in unexpected thrust asymmetry and a possible runway excursion.
Which aircraft AD 2006-26-06 applies to
Applies only to airplanes equipped with Rolls-Royce engines, as identified in Boeing Special Attention Service Bulletin 777-78-0064, Revision 1, dated November 30, 2006.
Whether AD 2006-26-06 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.
