Probable cause

The pilot’s unstabilized approach while landing with a tailwind and his subsequent failure to go around, which resulted in a hard landing.

Findings · 6

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, during the approach to land on a down-sloped, grass runway, the airplane was "a little high." He added that he attempted to land short of a rise in the runway, which resulted in a hard landing followed by a bounce. After the airplane settled back on the runway, "[he] believed we [the airplane] could still stop in time." He applied the brakes, but the airplane failed to slow, and he attempted to skid the airplane sideways "with little effect." As the airplane went over another rise in the runway, it floated off the ground. Subsequently, the airplane came to rest in the trees beyond the end of the runway. The airplane sustained substantial damage to both wings. The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The pilot reported that the weather at the accident site, about the time of the accident, was wind from 105°, gusting to 10 to 15 knots. The pilot landed on runway 27. An automated weather observation system about 13 nautical miles from the accident site reported, about the time of the accident, the wind was from 070° at 8 knots.
