At 14,000 feet, the crew reported severe vibration in engine No. 1, shut it down, and returned to the airport. Post-flight examination revealed a separated turbine shroud that punctured a fuel tank, causing a leak but no fire.

Incident Overview

The flight was climbing through 14,000 feet mean sea level (MSL) when the crew detected severe vibration in the number 1 engine. In response, they shut down the affected engine, declared an emergency, and executed a return to the departure airport. After landing, the aircraft taxied to the gate under its own power; passengers remained on board and were not evacuated.

Engine Examination

Subsequent inspection of the number 1 engine disclosed that a turbine shroud had separated from its mounting. The dislodged component penetrated the turbine exhaust case in the 6 to 9 o'clock position, passed through the engine cowling, and struck the number 2 outboard reserve fuel tank plate. The impact punctured the tank, resulting in a fuel leak. No fire was observed during or after the event.
