What happened
On an unspecified date leading up to the accident, a Cessna 414 departed on a flight carrying four adults and eight children. During the takeoff roll, the aircraft reached rotation speed at approximately 2,000 feet along the runway. As it climbed, the plane maintained a flat, nose-high attitude before striking trees at an altitude of roughly 30 feet, located about 4,223 feet from the point of lift-off. During the brief flight period of 20 to 30 seconds, the aircraft experienced two or three violent oscillations along its pitch axis.
The impact was followed by a fire, and all 12 fatalities were caused by smoke inhalation and thermal burns.
Findings
Investigations revealed that the aircraft was operating significantly over its maximum allowable weight, exceeding the limit by approximately 445 lbs. Additionally, the center of gravity was positioned 4.26 inches beyond the aft limit. The pilot, who was undergoing a checkride to remove a specific flight restriction, lacked formal training on this specific model and had minimal experience in conventional multi-engine aircraft. Furthermore, the pilot had not performed necessary weight and balance calculations prior to departure.
Contributing factors included inadequate preflight planning by the pilot in command and a failure by company management to ensure the pilot met insurance requirements, which included mandatory training at a Cessna flight school. The investigation also noted deficiencies in the certification process by the FAA examiner involved.
