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.

On July 24, 2026, at approximately 0815, an emergency was declared by the pilot-in-command of a Piper PA-28-140, serial number privacy data omitted, registration privacy data omitted, following a significant loss of engine power. The pilot executed a precautionary landing on the turf adjacent to the runway at a nearby airport, which was closed to fixed-wing traffic due to ongoing construction. The touchdown was completed without further incident, no injuries, aircraft damage, or airport infrastructure damage was reported.

A subsequent physical examination and engine teardown was conducted at Carroll County Airport. After removing the affected cylinder, an internal borescope inspection of the engine assembly revealed distinct evidence of corrosion on the camshaft lobe. Additionally, the corresponding exhaust valve was found seized in its valve seat. The heavily bent pushrod was noted to have remained entirely contained within the engine compartment wrapper.

A review of the historical aircraft and engine maintenance records established that the engine was the original power plant installed on the airframe. The engine had accumulated fewer than 3,000 total hours of operation over a 47-year service history, indicating extended periods of low operational utilization. No record of short-term or long-term engine preservation conducted by previous owners was located in the historical logbooks.

As the FAA filed it

ON JULY 24, 2026, AT APPROXIMATELY 0815, AN EMERGENCY WAS DECLARED BY THE PILOT-IN-COMMAND OF A PIPER PA-28-140, SERIAL NUMBER ^PRIVACY DATA OMITTED^, REGISTRATION ^PRIVACY DATA OMITTED^, FOLLOWING A SIGNIFICANT LOSS OF ENGINE POWER. THE PILOT EXECUTED A PRECAUTIONARY LANDING ON THE TURF ADJACENT TO THE RUNWAY AT A NEARBY AIRPORT, WHICH WAS CLOSED TO FIXED-WING TRAFFIC DUE TO ONGOING CONSTRUCTION. THE TOUCHDOWN WAS COMPLETED WITHOUT FURTHER INCIDENT, NO INJURIES, AIRCRAFT DAMAGE, OR AIRPORT INFRASTRUCTURE DAMAGE WAS REPORTED.

A SUBSEQUENT PHYSICAL EXAMINATION AND ENGINE TEARDOWN WAS CONDUCTED AT CARROLL COUNTY AIRPORT. AFTER REMOVING THE AFFECTED CYLINDER, AN INTERNAL BORESCOPE INSPECTION OF THE ENGINE ASSEMBLY REVEALED DISTINCT EVIDENCE OF CORROSION ON THE CAMSHAFT LOBE. ADDITIONALLY, THE CORRESPONDING EXHAUST VALVE WAS FOUND SEIZED IN ITS VALVE SEAT. THE HEAVILY BENT PUSHROD WAS NOTED TO HAVE REMAINED ENTIRELY CONTAINED WITHIN THE ENGINE COMPARTMENT WRAPPER.

A REVIEW OF THE HISTORICAL AIRCRAFT AND ENGINE MAINTENANCE RECORDS ESTABLISHED THAT THE ENGINE WAS THE ORIGINAL POWER PLANT INSTALLED ON THE AIRFRAME. THE ENGINE HAD ACCUMULATED FEWER THAN 3,000 TOTAL HOURS OF OPERATION OVER A 47-YEAR SERVICE HISTORY, INDICATING EXTENDED PERIODS OF LOW OPERATIONAL UTILIZATION. NO RECORD OF SHORT-TERM OR LONG-TERM ENGINE PRESERVATION CONDUCTED BY PREVIOUS OWNERS WAS LOCATED IN THE HISTORICAL LOGBOOKS.
