Engine power loss leads to multi-impact accident in multi-engine aircraft

Casualties unknown • Detroit, MI, US

A multi-engine airplane struck power lines, a house, and trees after experiencing a loss of power on the left engine during the initial takeoff climb.

What happened

During the initial takeoff climb, a multi-engine airplane experienced a loss of engine power. The pilot reported that all engine indications appeared normal until after takeoff. At approximately 50 feet above ground level, the pilot noticed a split in the manifold pressure and RPM, indicating a loss of power on the left engine.

In an attempt to avoid obstacles, the pilot turned to the south. During the flight, the aircraft collided with power lines, a house, a tree, and a fence. A second house also sustained fire and impact damage from flying debris. A passenger-rated occupant noted that the aircraft struggled to gain and maintain altitude and reported hearing the stall warning horn activate twice. The pilot attempted to land the aircraft in a field.

The investigation

Investigators examined both engines and found that both had sustained heat and impact damage. However, a post-accident inspection of the engines failed to reveal any mechanical failure or malfunction that would have caused the loss of engine power. A detailed inspection of the left engine propeller revealed that the propeller had not been feathered prior to the impact.

Probable cause

The loss of power on the left engine and the subsequent collision with obstacles, noting that the propeller was not feathered following the identification of the power loss.
