On October 3, 1986, a Piper PA-30 (registration N12BX) was involved in an aviation accident near Holbrook, AZ. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
Shortly after takeoff, the right engine lost power at about 450 feet. Despite feathering the propeller, the pilot could not maintain altitude, and the aircraft collided with terrain three miles south of the airport. The pilot dismantled and moved the aircraft before investigators arrived, potentially destroying evidence.
Loss of Power
Just after takeoff, the right engine experienced a loss of power at an altitude of approximately 450 feet. The pilot responded by feathering the right propeller. Despite this action, the pilot was unable to maintain altitude.
Collision
The aircraft subsequently collided with terrain about three miles south of the airport.
Post-Accident Actions
Prior to the arrival of investigators, the pilot dismantled and moved the aircraft. This action may have destroyed evidence relevant to determining the cause of the power loss.
Investigation Findings
During the investigation, no preimpact part failure or malfunction was found. The lack of evidence due to the dismantling and movement of the aircraft prevented a definitive determination of the cause of the power loss.
