## Discrepancy

HOUSING IS CRACKED IN THE BEARING RECESS AREA EXTENDING LATERALLY FROM THE RETRACT PRESSURE PORT.  THIS MAY BE CAUSED BY A LACK OF PISTON SNUBBING ACTION DURING GROUND NO-LOAD CONDITIONS.  SUBMITTER RECOMMENDS A RE-DESIGN OF THE HOUSING ASSEMBLY BY STRENGTHENING THE BEARING RECESS AREA AND RESTRICTING SPOILER MOVEMENT DURING NO-LOAD GROUND OPERATIONS.
