From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

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

(-23) Aircraft departed dallas love field. The right alternator light illuminated. It was reset with no further problems. When the aircraft was 50NM south of ponca city, Oklahoma the left engine started to run rough. The determination was made to stay VMC in order to avoid a possible single engine, no alternator IMC condition. ATC was asked for assistance in achieving this. No emergency was declared nor was priority asked for. The engine ran smoother at a reduced power setting and the flight was continued to the planned airport at Wichita, KS. Cargo was unloaded and the director of maintenance was notified. The aircraft ground run was normal. The aircraft departed back for denton, Texas. On 05/21/2002 the director of maintenance was called. The aircraft made it back with no problems. After the mechanic did some further troubleshooting, it was found an insulator was cracked on one of the left engines spark plugs. The aircraft was returned to service with no futher problems. It was suspected when the left engine got rough that the paralleling was thrown off and that is suspected what caused the right engine alternator to have to be reset. This matter is considered closed.
