31 May 1985 - General Aviation Flight 115

The aircraft was being operated as a General Aviation Flight 115 and was departing on a routine night flight. During takeoff/initial climb, the left engine lost power. The flight crew attempted to continue the climb-out, but following the application of water-methanol, the pilot lost directional control. Subsequently, the aircraft banked to the left, entered a descent and impacted between the paralled runways.

An investigation disclosed that the left propeller's blade angle was 21 degrees. No preimpact system malfunction or failure was found. The CVR recording indicated that the flight crew did not complete all of the items on the before taxi/takeoff checklist. One of the items (presumably not completed) was a check of the H.P. cock levers. the checklist required that the H.P. cock levers be in 'cruise lockout for takeoff'. The left H.P. cocklever was found between the 'fuel off' and 'feather' position. Movement to this position would have deactivated the auto-feahter system and shut down the left engine.
