Probable cause

The pilot’s failure to attain the proper touchdown point during landing, which resulted in a runway overrun.

Findings · 2

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

Before landing, the pilot overflew the airport and checked the runway environment. The pilot’s friend, who was flying another airplane, landed first on the 2,160-foot-long grass runway. The pilot then attempted to land on the same runway but aborted the first approach after he decided the airplane was too high and fast. During the second landing attempt, the airplane touched down on the main landing gear about the midpoint of the runway. The pilot stated that he held the nosewheel up and applied gentle braking, but the airplane did not slow at the rate he expected. The pilot considered aborting the landing; however, he believed that he would not be able to clear the trees at the end of the runway. The airplane ran off the runway, across a short overrun area, down a slope, and across a gravel road, where it impacted small trees. Postaccident examination revealed substantial damage to the fuselage and wing spars. The pilot reported that there were no preaccident mechanical malfunctions or failures that would have precluded normal operation.

Factual narrative

Prior to landing, the pilot overflew the airport and checked the runway environment. A friend of the pilot who was in another airplane, landed first on the grass runway, which was 2,160 feet long by 60 feet wide. The pilot then attempted to land on the same runway. The pilot aborted the first approach after he decided he was too high and fast. During the second landing attempt, the pilot touched the airplane down on the main landing gear about the mid-point of the runway, held the nose wheel up, and applied gentle braking. He stated the airplane slowed, but not at the rate he expected. He considered aborting the landing; however, he felt he would not have enough room to clear the trees at the end of the runway. The pilot then hoped a short overrun area would help stop the airplane, but the long grass concealed a 20 to 30 foot steep slope. The airplane exited the end of the runway, went down the slope, crossed a gravel road and impacted small trees, sustaining substantial damage to the fuselage and wing spars. After the accident, the pilot realized the runway had a significant down slope which he could not identify during his fly over prior to landing. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
