Requires operators of Boeing 767-200/300 aircraft with Pratt & Whitney PW4000 engines (line numbers 1–646) to perform initial and repeated inspections of thrust reverser auxiliary track beam assemblies, repair or replace any defects before further flight, and install improved liner/slider assemblies as specified. The stated purpose is to prevent excessive wear that can allow slider disengagement and release of thrust reverser parts, which could damage the aircraft or endanger people on the ground.
