Cessna 337G accident near Prescott, Arizona, September 2, 2006

The NTSB's narrative final · quoted from the NTSB record

The twin engine puller/pusher airplane departed the 7,550-foot-long runway, but failed to climb more than 100 feet above ground level (agl). The gear remained extended, and seconds before colliding with power lines, a transmission from one of the occupants indicated that they did not need assistance. During the accident sequence, the wreckage sustained extensive thermal damage. Two separate witnesses, who are pilots, saw the airplane after liftoff from the runway flying at low altitude just barely clearing the tops of trees. Both of the witnesses said the airplane was at a slow airspeed in a nose high attitude with the landing gear down, and, after about 1,000 yards, began a descent in the nose high attitude until contacting the power lines. Examination of the engines did not reveal any anomalies that would have precluded normal operation. Examination of the propellers indicated that the front engine was operating in the normal range at impact; however, the rear engine was producing little or no power, and had not been feathered. Performance calculations using the atmospheric conditions existing at the time and the estimated gross weight of the airplane indicated that with the rear engine inoperative and the landing gear extended, the airplane was not capable of climbing or maintaining level flight. A windmilling propeller would have greatly exacerbated the performance deficiency.
