Accident Overview
A Beech 58 aircraft, which had received a Supplemental Type Certificate (STC) for a Colemill Enterprise 'Foxstar' conversion, was being operated at night on a private airstrip. The airstrip was unlighted, uneven, and short. The pilot initiated the takeoff from the north end of the airstrip.
Witness Account
The owner of the airstrip heard the airplane and reported that the takeoff was started with partial power. Approximately five seconds later, the engines sounded as though they were at full power and continued to sound normal until the aircraft crashed.
Impact and Damage
The impact occurred about 100 feet east and 225 feet north of the southern runway threshold. Evidence indicated that the airplane had stalled and crashed in a steep descent. The leading edges of both wings exhibited accordion-style crush damage. Trees near the impact point were undamaged. The flaps were found in a retracted position, and the landing gear was found extended.
Mechanical Examination
No evidence of a preimpact mechanical deficiency was found.
Toxicology Findings
A toxicology test conducted at CAMI showed that the pilot's blood had an ethanol level of 98 mg/dL (0.098%). However, there was evidence of postmortem ethanol production. A urine test showed a low level of benzoylecgonine (0.272 µg/mL). Additionally, chlorpheniramine and pseudoephedrine, both over-the-counter antihistamines, were detected in the pilot's blood, urine, and liver fluid, but at levels that would not have resulted in impairment.
