What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

The crew declared an emergency. The engine restarted without crew input, and all parameters returned to normal. Further descent, approach and landing were uneventful on two engines. Maintenance determined that the hydromechanical unit had failed. The unit was replaced and the aircraft approved for return to service. Total time of the aircraft and hydromechanical unit was 14,000 hours, and 6,944 cycles.
