Background
On the day of departure, the pilot received a 30-minute familiarization flight upon completion of a "superstar" conversion. Emphasis during this flight was directed to engine gauges, fuel flow and counter, and power settings. The familiarization flight was conducted at 5,500 feet.
Flight and Engine Failure
The pilot obtained a weather briefing and filed a flight plan. Approximately 15 minutes after departure, while climbing through Flight Level 170, the pilot radioed that both engines had been lost. The aircraft was subsequently observed descending uncontrolled out of an overcast layer.
Aileron Separation and Descent
At about 1,000 feet above ground level, the right aileron separated. The descent continued uncontrolled.
Post-Accident Findings
Examination revealed that the fuel boost pumps were found in the "off" position. The Airplane Flight Manual (AFM) states that the boost pumps should be on during climb above 10,000 feet.
Pilot Training History
The pilot had been enrolled in an Aerostar transition school the previous month. During that training, a two-hour combined demonstration and flight evaluation flight was conducted. The instructor pilot recommended further multi-engine training.
Occupants
Both occupants were killed.
