Unsafe Condition
Crack on a 'dry' ADG (Hamilton Sundstrand part number in the 761339 series) in the aft area of the strut and generator housing assembly, due to a manufacturing anomaly with wall thickness below specification. Structural failure and departure of the ADG during deployment could result in damage to the aircraft structure and loss of hydraulics for flight controls in case of dual engine shutdown.

Required Actions
Inspect the part number of the installed ADG. For ADGs with part number in the 761339 series, check the serial numbers of the ADG and strut and generator housing assembly. If serial numbers are within specified ranges, perform a one-time fluorescent penetrant inspection of the ADG strut and replace the ADG if necessary.
