## Discrepancy

(CAN) THE TRANSMISSION WAS IN FOR A HARD LANDING SUDDEN STOPPAGE INSPECTION AND EXCESSIVE WEAR WAS FOUND ON THE INTERNAL SPLINES OF THE GEARSHAFT AS WELL AS ON THE EXTERNAL SPLINES OF THE SUNGEAR.THE WEAR WAS NOT A RESULT OF THE HARD LANDING.THIS IS THE SECOND TRANSMISSION IN THE LAST THREE MONTHS THAT HAS HAD THIS SAME PROBLEM.
