## Discrepancy

DURING NORMAL GEAR EXTENSION THE RT MLG DID NOT INDICATE LOCKED.  AFTER CYCLING THE GEAR & FISH TAILING IT INDICATED LOCKED & A NORMAL LANDING OCCURED.  THE ACTUATOR WAS REMOVED AND DISASSEMBLED AND FOUND THAT ONE OF FOUR PAWLS THAT INTERALLY LOCK THE COLLAR WAS STICKING & NOT COMPLETING THE LOCK.  THE ACTUATOR WAS OVERHAULED & BENCH CKD OK. IT WAS REINSTALLED AND OPS CKD OK.  THIS IS A RECURRING PROBLEM THROUGHOUT THE FLEET.  IT IS RECOMMENDED THAT 500 HR. I.R.A.N  BE MADE A SERVICE ITEM FOR CONTINUED AIRWORTHINESS.  IT IS BELIEVED ALSO, TO BE COLD RELATED.
