| Confidence Rating: |  Accident investigation report completed and information captured |
While taking off on a cross-country flight, the aircraft became airborne but would neither climb nor accelerate. The aircraft weight was 3,670 pounds, which was approximately 100 pounds below maximum. The density altitude was 6,000 feet msl. The aircraft was equipped with manual turbochargers which were not being used. According to the operating instruction for the aircraft, the turbochargers should be used for high altitude takeoff to obtain the desired manifold pressure of 29.5 inches at 2,700 rpm. The engines were capable of producing only 23.5 inches of manifold pressure without the turbochargers engaged and this power was insufficient for climb at the weight and speed used.
Probable Cause: the pilot-in-command's failure to use proper procedures and engage the turbochargers for takeoff from a high altitude airport. A factor was the high density altitude.
