What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: pilot stated: on downwind at mry, rwy 28R, the aircraft throttle was reduced to decrease airspeed. As the throttle was pulled back the engine immediately began to run rough. An emergency was declared and the aircraft was landed uneventfully. Just after touch-down, the engine quit and the aircraft was taxied off the runway under its own momentum. The cause of the rough running engine is under investigation and when the cause is determined, by maintenance personnel, a malfunction or defect report will be submitted. No pilot deviation and no 8010-11 generated. This terminates the investigation and this report is closed.
