Piper PA-23-250 N625SR accident near Perry, Florida

Probable cause

The total loss of engine power for reasons that could not be determined based on the available evidence.

NTSB analysis

According to the pilot, during cruise flight, the left fuel flow was "fluctuating." The pilot activated the electric fuel pump, and the fuel flow stabilized. After a few minutes, he deactivated the electric fuel pump, and the fuel flow remained "stable." The pilot began the descent from cruise altitude and selected the outboard fuel tanks on the fuel selector panel. During the descent, the right engine began to lose power, and it subsequently lost total power. After the pilot notified an air traffic controller of the engine failure and chose to continue to his original destination, the left engine lost total power. He then maneuvered the airplane toward a nearby airport; however, the airplane was unable to reach the airport, and it impacted trees and then came to rest upright.

The airplane had been fueled 2 days before the accident and had been flown for an undetermined amount of time since then. Local law enforcement reported smelling fuel at the crash site; however, the investigation could not determine whether the selected fuel tanks had fuel in them when the engines lost power. Although on-scene examination of the fuel system revealed that fuel was present throughout the system except at the right engine fuel flow divider, it could not be determined what role, if any, this played in the loss of power to both engines. The reason for the loss of power to both engines could not be determined.
