What was found
(CAN) THE ENGINE HAS BEEN INSTALLED AFTER OVERHAUL, AND ON GROUND RUN HIGH VIBRATION ON THE FORWARD POINT WITHIN LIMIT BUT ABNORMALLY HIGH. AFTER CONTACTING THE OVERHAUL FACILITIES, WE DID SOME TESTS FOR RESULT. THE VIBRATION WENT UP CLOSER TO THE LIMIT. AFTER THE VISIT BY A OVERHAUL FACILITIES TECH, IT WAS DETERMINED THAT THE ENGINE WAS OUT OF LIMIT AND WAS REMOVED AND SENT BACK TO THE OVERHAUL SHOP.
