Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that, during landing at dusk and into the setting sun, "flat light" conditions existed. The private, dirt airstrip increased in gradient as he landed to the west. When the airplane was about 75 knots airspeed, the pilot increased the flaps, attempted to bleed off airspeed, and touched down. He said the airplane landed hard "because…[he] literally did not see it coming." The nose landing gear collapsed, and the airplane nosed over. The airplane sustained substantial damage to the right wing, the lower fuselage, and the empennage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
