Background:  A number of Flap Actuators with P/N 601R93101-21 and 601R93101-25 were identified as having pinion gears that did not have acceptable certificates of conformance from the supplier.  This condition could result in flap failure.  To correct this, operators are required to replace the Inboard Flap Actuators that are non-conforming.
