1988-09-17: Piper PA-12 (N64CW) — Alfred Besch — Figure 8 Lake, AK

Figure 8 Lake, AK, US

On September 17, 1988, a Piper PA-12 (registration N64CW) operated by Alfred Besch was involved in an aviation accident near Figure 8 Lake, AK. Investigators recorded the probable cause as: The pilot's failure to maintain adequate clearance from terrain during the final approach, which resulted in a collision with a log and subsequent collapse of the main landing gear. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot landing in tall grass near a duck hunting shack overran the intended area, struck a log, and suffered main gear collapse during the rollout.

What happened

The pilot-in-command was attempting to land an aircraft in a field covered with one-foot-tall grass, located near a duck hunting shack. During the approach, the pilot realized he had overflown the intended landing area. He spotted two logs ahead and initially planned to land beyond them. However, he inadvertently landed between the two obstacles and struck the second log.

The impact caused significant damage to the aircraft. Despite striking the log, the pilot managed to keep the airplane airborne for a moment before it settled onto the ground. During the subsequent landing roll, the main landing gear collapsed under the stress of the impact and uneven terrain.

The investigation

Examination of the accident site and the aircraft revealed that the primary damage resulted from the direct contact with the log in the grassy field. The structural failure of the main landing gear was a consequence of the impact force rather than a pre-existing mechanical defect. No other mechanical failures were identified prior to the collision.

Findings

The accident sequence was initiated by the pilot's decision to land in an unprepared area with limited visibility due to the tall grass. The failure to accurately judge distance and terrain obstacles led to the collision. Contributing factors included the pilot's loss of situational awareness regarding the landing zone boundaries and the presence of hidden hazards in the vegetation.

Safety message

Pilots should exercise extreme caution when landing in unprepared fields, particularly those with tall grass that may obscure surface hazards such as logs, rocks, or ruts. Thorough visual inspection from altitude is essential to identify safe touchdown zones and avoid obstacles.

Probable cause

The pilot's failure to maintain adequate clearance from terrain during the final approach, which resulted in a collision with a log and subsequent collapse of the main landing gear.
