On December 12, 1991, a Grumman AA1B (registration N8859L) operated by James W. Winzer was involved in an aviation accident near Spur, TX. Investigators recorded the probable cause as: The pilot's inability to achieve rotation speed during takeoff due to degraded performance on a wet, muddy turf airstrip, which resulted in an overrun and collision with trees. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
The pilot aborted a takeoff attempt on a wet, muddy turf airstrip after failing to reach rotation speed due to degraded performance. The aircraft overran the runway and struck trees.
What happened
The pilot was attempting to depart from a wet, muddy turf airstrip when the flight encountered significant performance issues during the takeoff roll. Conditions on the airfield had been compromised by recent weather and ground traffic; it had rained one day prior to the departure, and four-wheel drive vehicles had previously operated on the grass and dirt surface.
Due to these degraded conditions, the airplane was unable to accelerate to the necessary rotation speed. Recognizing that a safe takeoff was no longer possible, the pilot initiated an abort of the takeoff sequence. Despite the attempt to stop, the aircraft overran the end of the runway. Upon exiting the paved or prepared surface, the airplane collided with nearby trees.
The investigation
The available source material does not provide specific details regarding mechanical examinations or post-accident inspections of the airframe and engines. The narrative focuses exclusively on the operational circumstances leading to the overrun.
Probable cause
