Resumo
This amendment adopts a new airworthiness directive (AD) that is applicable to General Electric Company CF6-6, -45, -50, -80A, and - 80C2 series turbofan engines. This action requires, prior to further flight, an ultrasonic immersion inspection for cracks in stage 1 fan disks, and, if necessary, replacement with serviceable parts. This amendment is prompted by reports of cracked fan disks found during routine shop inspections on fan disks manufactured between late 1984/ early 1985. The actions specified in this AD are intended to prevent fan disk failure due to cracks, which could result in an uncontained engine failure and damage to the aircraft.
