Airworthiness Directive 2000-11-28
recurringAirworthiness Directives; Boeing Model 747-400 and 767-200 and -300 Series Airplanes Powered by Pratt & Whitney Model PW4000 Series Engines
What this AD requires
This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 747-400 and 767-200 and -300 series airplanes, that requires repetitive inspections to detect damage and wear of the auxiliary track assembly of the thrust reverser, and corrective actions, if necessary. This amendment also requires eventual repair of the auxiliary track assembly, or replacement of the slider and liner or the entire assembly, with new, improved parts, which, when accomplished, would terminate the repetitive inspections. This amendment is prompted by reports of damage and wear to the auxiliary track assembly. The actions specified by this AD are intended to prevent a slider disengaging from the auxiliary track assembly, which could lead to separation of a portion of the thrust reverser from the airplane during flight, possible impact of separated portions on airplane structure, and consequent possible rapid decompression of the airplane, reduced controllability of the airplane, or reduced structural integrity of the fuselage.
Which aircraft AD 2000-11-28 applies to
Requires detailed visual inspection of upper/lower auxiliary track assemblies on each thrust reverser half to detect track lip damage/slider disengagement, per Boeing SB 747-78A2164 Rev 2 (Model 747-400 series airplanes) or SB 767-78A0079 Rev 2 (Model 767 series airplanes), as applicable; initial inspection within 3,000 flight cycles or 90 days after effective date.
Whether AD 2000-11-28 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.
