On July 4, 2001, a Lake LA-4 (registration N1235L) was involved in an aviation accident near Mulberry, FL. Investigators recorded the probable cause as: The loss of engine power for undetermined reasons. A factor was rough and uneven terrain. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An airplane experienced engine power loss after lift-off, leading to an emergency landing in a clearing. The aircraft struck rough terrain and caught fire. Examination found no mechanical failure.
Incident Overview
Shortly after lift-off, the engine rpm dropped to idle and then ceased entirely. The pilot initially attempted to return to the departure airport but instead chose a nearby clearing for an emergency landing.
Emergency Landing and Impact
As the pilot maneuvered the airplane for the emergency landing, it collided with rough and uneven terrain and burst into flames. No further details about the terrain or the extent of the fire were provided.
Post-Accident Examination
Examination of the oil filter element and suction screen revealed no contamination. The pilot estimated that approximately 40 gallons of fuel were on board at the time of the accident. A thorough inspection of the airframe and engine assembly did not disclose any mechanical malfunction or component failure.
Investigation Findings
The investigation did not identify a specific cause for the engine power loss. No mechanical issues were found that could explain the engine's behavior. The absence of contamination in the oil system and the lack of any detected failures leave the reason for the power loss undetermined.
