Accident Overview
The airplane departed on runway 31 in instrument meteorological conditions (IMC) and turned right to a heading of 090°. Radar contact was acquired about 1 to 2 miles north of the airport, typically at an altitude of about 700 feet above ground level. Subsequently, the airplane crashed about 2 miles north of the airport.
Witness and Wreckage
A witness reported hearing a loud engine noise before the plane crashed. The wreckage path was oriented along a westerly heading over an area of about 380 feet. Evidence indicated an in-flight breakup. An outboard portion of the right wing was found about 150 feet from the main impact crater.
Examination Findings
Examination revealed the right wing had failed near the production seam. The right spar exhibited features typical of an upward bending overstress separation. No other evidence of preimpact aircraft or engine malfunction was found. The airplane's gross weight was estimated to be about 4,696 pounds; its maximum limit was 4,300 pounds.
Pilot Experience and Weight
The pilot's logbook indicated that he had flown only 2 instrument approaches in the previous 14 months. The airplane's excessive gross weight was noted as a factor. All three occupants were killed.
