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 April 18, 2026, at approximately 11:37 am local time, during the second instructional flight of the day, a dual instructional crew (flight instructor and student pilot) operating a Cessna 172 experienced a sudden and complete engine failure while conducting training operations. During a descent from 2,000 to 1,300 feet at approximately 1,800 RPM, a loud “pop” was heard, followed by an immediate total loss of engine power. The crew executed emergency procedures and made multiple unsuccessful restart attempts before conducting a forced off-airport landing in a field approximately 5 NM west of Shafter airport (minter field). The aircraft landed without further incident, and no injuries or damage were reported. A preliminary maintenance inspection, including a compression check, revealed that three of the four cylinders had zero compression, despite the engine having only 484.2 hours since major overhaul (tsmoh). The engine was subsequently replaced in the field. The root cause of the compression loss remains under investigation by the operator’s maintenance team.

As the FAA filed it

ON APRIL 18, 2026, AT APPROXIMATELY 11:37 AM LOCAL TIME, DURING THE SECOND INSTRUCTIONAL FLIGHT OF THE DAY, A DUAL INSTRUCTIONAL CREW (FLIGHT INSTRUCTOR AND STUDENT PILOT) OPERATING A CESSNA 172 EXPERIENCED A SUDDEN AND COMPLETE ENGINE FAILURE WHILE CONDUCTING TRAINING OPERATIONS. DURING A DESCENT FROM 2,000 TO 1,300 FEET AT APPROXIMATELY 1,800 RPM, A LOUD “POP” WAS HEARD, FOLLOWED BY AN IMMEDIATE TOTAL LOSS OF ENGINE POWER. THE CREW EXECUTED EMERGENCY PROCEDURES AND MADE MULTIPLE UNSUCCESSFUL RESTART ATTEMPTS BEFORE CONDUCTING A FORCED OFF-AIRPORT LANDING IN A FIELD APPROXIMATELY 5 NM WEST OF SHAFTER AIRPORT (MINTER FIELD). THE AIRCRAFT LANDED WITHOUT FURTHER INCIDENT, AND NO INJURIES OR DAMAGE WERE REPORTED. A PRELIMINARY MAINTENANCE INSPECTION, INCLUDING A COMPRESSION CHECK, REVEALED THAT THREE OF THE FOUR CYLINDERS HAD ZERO COMPRESSION, DESPITE THE ENGINE HAVING ONLY 484.2 HOURS SINCE MAJOR OVERHAUL (TSMOH). THE ENGINE WAS SUBSEQUENTLY REPLACED IN THE FIELD. THE ROOT CAUSE OF THE COMPRESSION LOSS REMAINS UNDER INVESTIGATION BY THE OPERATOR’S MAINTENANCE TEAM.
