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.

(.19) On January 21, 2002, at 1100 pacific standard time, a Beech B36TC, N6427N, contacted the runway surface with the left wingtip during takeoff from the Mammoth Lakes airport, Mammoth Lakes, California. The airline transport certificated pilot and four passengers were not injured. The airplane was substantially damaged. The personal flight was operated by the owner under 14 CFR part 91 and was destined for van nuys, California. Visual meteorological conditions prevailed and no flight plan was filed. The airplane departed on runway 27 (7,000 feet long by 100 feet wide, asphalt). The pilot reported that the airplane encountered a wind gust, which caused one wing to lift and the other to drop and contact the runway. The recorded automated weather observing system (AWOS) surface wind, 48 minutes after the accident, was from 200 degrees at 18 knots with gusts to 31 knots. Following the wingtip contact with the runway, the pilot aborted the takeoff and brought the airplane to a stop on the remaining runway. (-23) pilot was departing Mammoth Lakes, CA airport on runway 27. Shortly after liftoff, an unexpected strong gust of wind directly from his left was encountered and the pilot was unable to keep the left wing tip from striking the runway. The pilot landed back on the runway and taxied to parking. The left wingtip was damaged, left wing skin wrinkled on top, the aft left spar was bent and the left aileron was damaged. Pitot tube and mast was damaged. No injury to any of the five occupants.
