## Discrepancy

AIRCRAFT 9V-SWH WAS UNDERGOING “C06” CHECK IN HANGAR ENVIRONMENT. A LANDING GEAR ALTERNATE EXTENSION TEST WAS SCHEDULED. WHILE ON JACKS, THE INITIAL GEAR LEVER UP RETRACTION TEST 
WAS COMPLETED SUCCESSFULLY. HOWEVER, WHILE STILL PERFORMING THE LANDING GEAR ALTERNATE EXTENSION TEST, WHEN ALL LANDING GEARS WERE LOWERED, A LOUD SOUND WAS BRIEFLY HEARD OUTSIDE OF THE COCKPIT. UPON INSPECTION, THE RIGHT-HAND MAIN LANDING GEAR SIDE BRACE LINK WAS FOUND DAMAGED WITH NIL FURTHER FINDINGS OR DAMAGE NOTED ON THE LANDING GEARS.
