Unsafe Condition
Improper machining of the pump housing on landing gear emergency hand pumps (part number 101-388007-3, serial numbers 2702 through 2833) resulted in insufficient groove depth to retain a snap ring, which retains the check valve in its proper position within the housing. This could result in inability to properly lower and lock the landing gear in the event of primary system failure.

Required Actions
