This amendment adopts a new airworthiness directive (AD) that is applicable to General Electric Company (GE) CF6-80C2 series turbofan engines. This action requires an initial and repetitive brake holding torque check of the fan reverser center drive unit (CDU), visual inspection of the translating cowl inner bondment seal, and functional check of the translating cowl auto re-stow system. This action also requires removal and replacement of certain CDU's as a terminating action to the repetitive check and inspection program. This amendment is prompted by a report of a CDU not able to hold the fan reverser translating cowl at the required position when manually driven to its stow position during routine maintenance. The actions specified in this AD are intended to prevent the loss of the CDU's brake holding feature, which could result in possible movement of the fan reverser translating cowl towards the deploy position in flight.
