A United Boeing 757-200, registration N41140 performing flight
UA-317 from Newark,NJ (USA) to Dublin (Ireland), was enroute at FL370 about 210nm westnorthwest of Gander,NL (Canada) when the crew declared PAN PAN reporting high engine (RB211) vibrations and decided to return to Newark. The aircraft descended to FL250 and landed safely back on Newark's runway 22L about 5 hours after departure and about 2:50 hours after leaving FL370.
The rotation was cancelled.
A listener on frequency reported: "a UAL flight declared a pan pan and diverted to EWR due to 'high engine vibration'".
On Oct 12th 2023 the Canadian TSB reported: "While in cruise about 2 hours and 40 minutes into the flight (at 52°23' N, 055°01' W) the flight crew heard a bang and noted a momentary yaw of the aircraft. The flight crew noted the EICAS message for number 1 engine (Rolls-Royce RB211-535E4B) vibration, consulted the QRH, reduced left engine power until the vibration decreased below the amber range, and declared an emergency. The flight crew consulted with company maintenance control personnel and decided to return to KEWR. The diversion was coordinated with ATS, and the flight landed at KEWR without further incident. Company maintenance identified a crack at the 1 o'clock position on the number 1 engine exhaust nozzle and removed and replaced the engine."
