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 21, 1998, YAK-52 aircraft, N151PA, serial no. 855712, had a maintenance test flight for propeller balancing. After landing rollout, pilot released brakes. At that time the main gear collapsed, with the nose gear remaining fully extended. An inspection of the aircraft by inspector edmond pottle and ast jo anne flock revealed minor skin damage to the bottom, aft section of the tail directly beneath the rudder. Minor damage was also found on the rudder skin and left aileron skin. Aircraft was placed on jacks and, with the pneumatic system fully charged, the gear was tested and found to be operational. The aircraft was built and returned to service on June 17, 1998. During the conditioninspection on June 17, 1998, the pneumatic gear system had been serviced and tested and was found to be fully operational. The system requires 5 atmospheres of pneumatic pressure to operate. The aircraft is being repaired, and the pneumatic system will be tested for leaks and be repaired.
