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.

Acft crashed on landing, other circumstances are unknown. (.19) on June 5, 1999, at 0705 Alaska daylight time, a tundra tire equipped PA-12 airplane, N78456, sustained substantial damage during an emergency landing at the lake Hood strip, Anchorage, Alaska. The airline transport pilot and sole passenger were not injured. The airplane was being operated under 14 CFR part 91 as a personal flight. The flight departed Anchorage international airport, Anchorage, at 0605, on a fishing trip to the alexander river, about 40 miles to the north. Visual meteorological conditions prevailed at the time of the accident, and a flight plan was filed with a relative. The pilot and passenger spoke with the NTSB ivnestigator-in-charge at the accident site at 0715. They said that while attempting to land on a gravel bar on the alexander river, the airplane hit hard, bounced, and the pilot aborted the landing. Both said they heard a loud noise during the landing, and then could see that the right wheel was bent. The pilot decided to return to Anchorage, and land on the gravel strip at lake Hood. During the landing, the right main landing gear collapsed, and the right wingtip struck the ground, damaging the wingtip and right wing strut. (-23) while trying to land at big susitna sandbar, the aircraft touched down when the pilot felt a bump, he aborted the landing and took off again. He made a visual inspection and noticed that the right landing gear appeared to be out at a 30 degree angle. He then headed back to lake Hood strip, called the tower and declared an emergency landing. When arriving at lake Hood strip, the pilot flew by the tower where they confirmed that the landing gear was damaged. Substantial damage to the aircraft right main landing gear and right wingtip was sustained when the right main landing gear collapsed on landing. (.4) the pilot was attempting to land on an off airport gravel bar, with a right crosswind of 15 to 20 knots. He described the airplane developing a high rate of descent prior to landing, and increasing power to slow the descent. He said the airplane landed hard, bounced, and he aborted the landing. He then observed the right main wheel misaligned about 30 degrees. The pilot returned to the departure airport's gravel airstrip for an emergency l anding. During the landing, the right main landing gear strut collapsed, damaging the right-front lift-strut.
