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.

(-23) This Lear jet (LR-45) was being operated by a & p mechanics employed by turbine engine specialists (TEHR262X) for the purpose to taxi out for an engine test run on the #1 (left engine). During taxi it was necessary to stop the aircraft for motor vehicle traffic. The mechanic advanced the throttles for taxi and to climb a 15 to 20 foot hill. When the mechanic attempted to reduce the throttles only the #2 (right engine) could be retarded. The # 1 engine was at a high power setting and could not be reduced. The aircraft left 4 skid marks as the main tires were locked for approximately the length of a little more than a football field. The mechanics could not shut down # 1 engine. Control of the aircraft was lost with the # 1 engine at a high power setting. The right wing impacted the corner of a hanger. The nose gear broke and an embankment stopped the aircraft. The mechanics were then able to shut down both engines and exited the aircraft with no injuries. This report is closed.
