What happened
During the initial climb phase immediately following lift-off, the right engine of the aircraft lost power. A witness reported hearing a noise and observing flames emanating from the right engine cowling as the plane ascended. After reaching an altitude of approximately 200 feet, the aircraft entered a turn and subsequently descended through a small grove of trees. The aircraft then crashed into a pasture and was destroyed by fire.
At the time of takeoff, the aircraft's gross weight was approximately 11,050 lbs, which exceeded its maximum certified weight limit of 9,700 lbs. Additionally, the center of gravity (CG) was located behind the aft limit. The pilot was reportedly aware of the gross weight issue prior to departure.
The investigation
Post-accident examination of the aircraft revealed that the left engine propeller was in the feathered position at the time of impact, while the right propeller was not feathered. A mechanical inspection of the right engine determined that the number 3 cylinder intake valve had failed due to fatigue.
