On November 18, 1990, a Beech J-35 (registration N8263D) operated by Kroll, Douglas was involved in an aviation accident near Brighton, CO. No fatalities were reported. Investigators recorded the probable cause as: An improper STC installation that caused a fuel feed line failure between the fuel feed transducer and the fuel manifold, leading to total engine failure. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An aircraft experienced total engine failure ten minutes into flight during a climb. The pilot executed an emergency landing on rough terrain, sustaining minor damage and no injuries.
What happened
The incident occurred shortly after takeoff, specifically ten minutes into the flight while the aircraft was in a climb toward its cruise altitude. During this phase, the engine failed completely, necessitating an immediate emergency landing. The pilot selected a site characterized by rising and rough terrain for the forced landing. Upon inspection following the event, the aircraft was found to have sustained only minor damage. Fortunately, the pilot was not injured during the incident.
The investigation
A thorough examination of the aircraft was conducted to determine the root cause of the mechanical failure. Inspections revealed a critical failure in the fuel feed line located between the fuel feed transducer and the fuel manifold. Further investigation determined that this failure was the result of an improper Supplemental Type Certificate (STC) installation.
Probable cause
An improper STC installation that caused a fuel feed line failure between the fuel feed transducer and the fuel manifold, leading to total engine failure.
