N72BHHartline John Bon HARTLINE PULSAR I · 1990

On February 25, 2024, about 1645 central standard time, a Pulsar 1 airplane, N72BH, was destroyed when it was involved in an accident near Patterson, Louisiana. The pilot sustained serious injuries. The airplane was operated as a Title 14 Code of Federal Regulations (CFR) Part 91 personal flight.

The owner, who was flying the airplane at the time of the accident, did not provide a report of the accident. Airplane registration documents indicated that the amateur-built airplane was purchased by the owner on November 22, 2023. According to the owner, the accident flight was the airplane’s first flight after the purchase. Shortly after takeoff, the airplane’s engine lost all power, and the owner attempted to land the airplane in an open area on airport property. During the attempted landing, the airplane struck a fence and impacted the ground. A postimpact fire ensued and destroyed the airplane.

Postaccident examination of the airplane revealed that the fuselage cabin section and inboard wings were almost completely destroyed by the postimpact fire. The examination confirmed flight control system continuity to the extent possible.

The airplane was powered by a Rotax model 582 2-stroke engine. A partial teardown examination revealed internal corrosion on the No. 2 cylinder wall and on the No.2 connecting rod. There was evidence that the No. 2 piston had seized within its cylinder. No other preimpact anomalies were noted.

According to engine maintenance records, the engine had undergone an overhaul on October 21, 2014, and was installed on the accident airplane on August 22, 2015. There was an entry for a condition inspection on November 6, 2016, and no further entries until January 15, 2024, which indicated that the propeller reduction gearbox was removed and sent to a Rotax mechanic for overhaul and modification of the gear reduction ratio. Another entry dated January 17, 2024, indicated that the engine control cables were replaced.

The airframe maintenance records were reviewed, and the most recent entry, dated November 6, 2016, indicated that a condition inspection was performed on that date.

The engine operating manual details procedures for preserving the engine for various periods of inactivity. However, no maintenance entries were found indicating that the storage procedures had been completed.

At the time of the accident, the owner did not hold a pilot certificate. He previously held a student pilot certificate, but it was revoked by the FAA in 1975.
