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.

High density altitude and over gross led to stall and collision with a residence on climbout from sun. (.4)the pilot initiated takeoff from runway 13, a 6,600 foot paved runway. Shortly after the aircraft became airborne, it veered left, flew low, gained enough altitude to cross the highway and flew over the power lines east of the highway, then clipped the trees and went nose in into the subdivision. The investigation revealed that the pilot departed with 20 degrees of flaps. According to the aircraft owner's manual, the use of flaps is not recommended for crosswind takeoffs. The reported winds were from 200 degrees magnetic at 7 knots. The calculated density altitude at the airport at that time was 7,630 feet.
