A pilot was seriously injured when the airplane lost right engine power on initial climb, banked, inverted, and descended into trees. Investigation found no anomalies; right engine tested normal.

Accident Overview

The airplane was destroyed when it impacted trees and terrain following an in-flight loss of right engine power during initial climb out. The pilot sustained serious injuries.

Witness Account

A witness reported that after takeoff, the airplane "all of a sudden began to bank, like it was going to make a turn and head north." The plane then inverted, and the right wing began to dip under. The airplane then went straight down into a wooded area adjacent to the runway.

Pilot Statement

The pilot stated: "Starboard engine failed on takeoff (downwind engine) with gear [and] flaps down. At an altitude of 100-200 ft engine failed. As pressure to port rudder was applied and attempting to place fuel selector switch in ALT fuel position, A/C violently departed to the right. (rolled)." The pilot also said, "I tried to re-start the right engine but had no time."

Flight Manual Guidance

The airplane's flight manual includes procedures for engine failure after lift-off and in flight. It states: "An immediate landing is advisable regardless of take-off weight." The checklist for continued flight requires immediate pilot response: landing gear and flaps up, throttle on the inoperative engine closed, propeller feathered, power on the operative engine as required, and airspeed maintained at engine failure speed (99 knots or 114 mph maximum) until obstacles are cleared. After positive control is established, the inoperative engine should be secured. The manual notes: "The most important aspect of engine failure is the necessity to maintain lateral and directional control. If airspeed is below 80 kts (92 mph), reduce power on the operative engine as required to maintain control." A caution advises the pilot to determine the reason for engine failure before attempting an air start.

Investigation Findings

An on-scene investigation was conducted. No anomalies were found. The right engine produced full power during a test run.
