Lincoln, IL, US

On October 21, 1989, a Piper PA-38-112 (registration N9487T) was involved in an aviation accident near Lincoln, IL. Investigators recorded the probable cause as: The pilot's decision to attempt takeoff on a runway that was too short and had inadequate surface conditions for safe departure, resulting in failure to climb and subsequent collision with terrain and obstacles. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot attempted takeoff from a closed airport with limited runway length and wet conditions, resulting in failure to climb and collision with residential structures.

What happened

The pilot landed at an airport that was currently closed for construction while the aircraft was operating on low fuel reserves. After refueling, the pilot attempted to depart using only approximately 1,200 feet of available runway. The conditions included a wet sod surface and reported long grass.

After initiating takeoff, the aircraft failed to achieve a climb gradient. To avoid nearby obstructions such as trees and houses, the pilot executed a right turn. However, the aircraft struck two houses before coming to a stop.

The investigation

The investigation focused on the operational constraints at the time of the accident. Key factors included the reduced runway length available for takeoff, the wet and soft surface conditions, and the initial low fuel state that necessitated an earlier landing.

Findings

The primary issues identified were the insufficient runway length for the aircraft's performance capabilities under the given weight and environmental conditions. The decision to attempt takeoff with only 1,200 feet of usable pavement on a wet, grass-covered surface contributed significantly to the inability to climb.

fuel exhaustion was not the direct cause of the crash but was a factor in the initial landing. The critical failure was inadequate takeoff performance. The pilot was not injured in the incident, though the aircraft sustained significant damage from the collision with residential structures.

Probable cause

The pilot's decision to attempt takeoff on a runway that was too short and had inadequate surface conditions for safe departure, resulting in failure to climb and subsequent collision with terrain and obstacles.
