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 insufficient wall thickness, could lead to structural failure and departure of the ADG during deployment. This could result in damage to the aircraft structure and, if activated by a dual engine shutdown, loss of hydraulics for the flight controls, potentially causing loss of control of the airplane.

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 the strut and generator housing assembly. If serial numbers are within specified ranges, perform initial and subsequent repeat fluorescent penetrant inspections of the ADG strut. Perform a fluorescent penetrant inspection after each unscheduled in-flight ADG deployment and a general visual inspection after each unscheduled on-ground ADG deployment. Replace parts as necessary.
