## Discrepancy

(CAN) LT MAIN GEAR OLEO WOULD NOT HOLD AIR CHARGE. OLEO FOUND LOW SEVERAL TIMES AND RECHARGED. UPON INVESTIGATION IT WAS FOUND THAT THE RETAINING NUT FOR THE UPPER OLEO SUPPORT TUBE WAS CRACKED, CAUSING AIR LEAKAGE. FURTHER INVESTIGATION ALSO REVEALED CORROSION ON THE THREADS OF THE SUPPORT TUBE. SUPPORT TUBE AND NUT WERE REPLACED.. .
