Probable cause

The pilot’s failure to maintain adequate spacing from the lead airplane while landing following revised landing instructions, which necessitated that the pilot conduct an improper landing flare and resulted in a hard landing.

Findings · 3

NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.

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 he was the second airplane in a flight of two and had been instructed by the air traffic controller to land on the orange dot on the runway (dots were used to facilitate multiple landings for the fly-in). During the descending turn from the base leg to the final leg, the pilot saw a third airplane. The third airplane appeared to be landing straight-in to the same runway. The air traffic controller instructed the flight of two to land further down the runway, on the green dot, to accommodate the third airplane. As the pilot adjusted the engine power and descent rate for the new landing point, he noted that the closure rate with the lead airplane in his flight of two had increased and that the lead airplane decelerated quickly as it landed. The pilot increased the pitch to overfly and avoid a collision with the lead airplane. After he confirmed that he was past the lead airplane, he adjusted the pitch and engine power to land, but the airplane landed hard. During the landing, the airplane settled left wing down and veered left off the runway, and the left main landing gear collapsed. The airplane sustained substantial damage to both wings and the fuselage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.

Factual narrative

The private pilot reported that he was the second airplane in a flight of two and had been instructed by the air traffic controller to land on the orange dot on runway 27 (dots used to facilitate multiple landings for the fly-in). During the descending turn from the base leg to the final leg, the pilot observed a third airplane. The third airplane appeared to be landing straight-in to runway 27. The air traffic controller instructed the flight of 2 to land further down the runway, on the green dot, to accommodate the third airplane. As the pilot adjusted his engine power and descent rate for the new landing point, he noted that the closure rate with the lead airplane (in his flight of 2) increased and the lead airplane decelerated quickly as it landed. The pilot increased the pitch of the airplane to overfly and avoid a collision with the lead airplane. After he confirmed that he was past the lead airplane, he adjusted the pitch of the airplane and engine power to land, but landed hard. During the hard landing the airplane settled left wing down and veered to the left off the runway, and the left main landing gear collapsed. The airplane sustained substantial damage to both wings and the fuselage. There were no mechanical anomalies with the airplane that would have precluded normal operations.
