Narrative:
Spatial disorientation on the part of the captain shortly after a runway 28 takeoff in IMC. The attitude and heading instruments had not become operationally usable due to slow warm up times. Crashed in woods in a 30deg nosedown and 90deg left bank attitude some 1,75 miles north of the airport.
PROBABLE CAUSE: "The loss of control of the airplane following the takeoff in instrument meteorological conditions as a result of the pilot's use of attitude and heading instruments which had not become operationally usable and/or his partial reliance on the copilot's flight instruments which resulted in an abnormal instrument scan pattern leading to the pilot's disorientation. Contributing to the accident was the pilot's hurried and inadequate preflight procedures."
