## Discrepancy

(CAN) THE PW150A ENGINE FLEET IS SUBJECT TO OIL SAMPLING/MONITORING. SAMPLES ARE ROUTED TO THE ENG MANUFACTURER FOR ANALYSIS. NOTIFICATION WAS RECEIVED THAT ENG WAS SHOWING OIL SAMPLE CHARACTERISTICS CONSISTENT WITH POSSIBLE 2.5 BEARING SEAL DETERIORATION. UPON RECOMMENDATION FROM P&W THE ENGINE WAS REMOVED AND ROUTED FOR INSPECTION. THE SHOP INSPECTION RESULTS CONFIRMED 2.5 BEARING SEAL WEAR. THE 2.5 BEARING SEAL IS SUBJECT TO A SERVICE BULLETIN (SB35342) WHICH REPLACES THE AFFECTED PARTS. THIS ENGINE WAS PRE-SB AND WILL SUBSEQUENTLY UPDATED DURING THIS SHOP VISIT. (TC# 20190622003)
