Spearfish, SD, US

On July 1, 1998, a Piper PA-22-108 (registration N5181Z) was involved in an aviation accident near Spearfish, SD. Investigators recorded the probable cause as: the pilots improper preflight planning, which failed to detect the fuel selector positioned on the left fuel tank, which had insufficient fuel, resulting in fuel starvation, and the loss of engine power. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

An airplane experienced a partial loss of engine power, prompting a forced landing that resulted in impact with trees and terrain. Post-accident examination found no pre-impact mechanical anomalies, but only unusable fuel in the selected tank.

Accident Overview

The accident involved an airplane that suffered a partial loss of engine power during flight. The pilot subsequently conducted a forced landing, during which the aircraft impacted trees and the terrain before coming to rest.

Pilot Statements

The pilot reported the power loss to a physician, describing it as a loss of approximately 70% of engine power. In a later statement to an attorney, the pilot indicated that the airplane had experienced fuel exhaustion.

Post-Accident Examination

Following the accident, an examination of the airplane revealed no mechanical anomalies that were not associated with the impact. Emergency responders and Federal Aviation Administration inspectors arrived at the scene within two hours of the accident. They observed no fuel leaking from the airplane and detected no odor of fuel. Inspection of the left fuel tank showed that it contained only unusable fuel. The fuel selector was found positioned to the left fuel tank.

Conclusion

The investigation did not identify any pre-impact mechanical issues. The combination of pilot reports and post-accident fuel findings suggests the power loss may be linked to fuel availability, but no definitive cause was stated in the source.
