The crash had killed the former president of Sikorsky, Jeffrey Pino, and his friend.
Based on eye witnesses reports and local airport radar data, investigators found that the plane was making a loop before it plunged into the ground.
The aircraft handbook forbid the maneuver if the weight in the fuselage tank exceeds 150 lbs. The fuselage tank was modified to become a second seat and the person sitting there had weight more than 150 lbs. Pushing the aircraft into such a condition could create a “tail heavy” scenario.
A final is expected to be out within the next two months.
