## Discrepancy

LT MLG UPLOCK ACTUATOR WOULD NOT RELEASE THE LANDING GEAR DURING 'FREE FALL' TEST. DISSAMBLY OF ACTUATOR REVEALED A NON APPROVED SPRING THAT WAS 0.125 INCHES SHORTER THAN THE ORIGINAL MANUFACTURER.  THE SCARCITY OF REPLACEMENT PARTS FOR THIS UNIT MAY HAVE CAUSED A PREVIOUS REPAIRER TO USE UNAPPROVED PARTS.
