The solo student pilot, on her first cross-country flight, was departing on runway 19R. Just after rotation, the airplane veered to the left, and went off the left side of the 7,575 feet long by 150 foot wide runway. The airplane came to rest in a ditch that borders the runway, and sustained substantial damage to the wings and fuselage. The pilot stated that prior to her being cleared for takeoff, a DeHavilland DHC-8 departed from the opposite direction on the same runway. She said that about 2 minutes elapsed between the larger aircraft's departure, and her departure. The Air Traffic Controller's Manual (FAA order 7110.65M) relating to wake turbulence application, states that a 3-minute interval be observed between departures of large and small aircraft, and the issuance of a wake turbulence advisory before clearing the aircraft for takeoff. The manual identifies a DeHavilland DHC-8 as a large turboprop aircraft, and a Cessna 152 as a small aircraft. Review of air-ground radio communications tapes revealed that the total time separation between the two departures was 1 minute, 49 seconds, with no issuance of a wake turbulence advisory.
Probable Cause: The loss of control due to wake turbulence, and the issuance of an improper takeoff clearance by air traffic control personnel. A factor associated with the accident was air traffic control personnel's failure to issue a safety advisory.
