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.

Narrative: history of flight: on January 28, 1995, a Beechcraft, BE-A36, N128TJ, on an IFR flight plan from hot springs, AR, to memphis, TN declared an emergency at 1715 CST, after the engine failed at 7,000 feet MSL, 10 NM northwest of Stuttgart, AR. Aircraft received vectors to Stuttgart Municipal Airport and landed without incident at 1724 CST. Damage to aircraft: the aircraft sustained no damage, but there was engine damage to the right rear cylinder, in that the rocker arm boss area was broken. The engine did not quit, but lost substantial power. Test and research: when the cylinders were overhauled the rocker arm bosses had brass bushings installed. Drilling the rocker arm for the bushings may have weakened the rocker arm, although, there were also gray areas with small holes in the casting, indicating that it could have been a weak area when the rocker arm was cast. This engine was overhauled prior to service bulletin M92-6 being issued, directing that during overhaul the rocker arm be drilled through and install a helicoil. This incident is closed.
