Probable cause
The flight instructor's inadequate supervision and the dual student's premature lift off which resulted in inadequate airspeed, a stall, and collision with the ground.
Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
While practicing soft-field takeoffs in a single-control throw-over yoke aircraft, the student pulled the aircraft off the runway prior to attaining enough speed to remain airborne. Immediately after becoming airborne, the aircraft banked sharply to the left, dropped onto the runway, and bounced back into the air. According to the instructor pilot, when he saw that the aircraft was going to lift off prematurely, he commanded the student to lower the nose. But, the student did not lower the nose enough, and the instructor did not apply forward pressure to the central control pedestal to keep the aircraft from lifting off too early. It was later discovered that the left wing had impacted the asphalt surface when the aircraft dropped back onto the runway.
Factual narrative
On April 1, 1998, approximately 1110 Pacific standard time, the left wing of a Beech 35-C33, N1310A, impacted the runway immediately after a premature liftoff at Portland-Hillsboro Airport, Hillsboro, Oregon. The certified flight instructor and his student, who holds a private pilot certificate, were not injured, but the aircraft, which was owned and operated by Tektronix Flying Club, sustained substantial damage. The 14 CFR Part 91 local instructional flight was being operated in visual meteorological conditions. No flight plan had been filed, and there was no report of an ELT transmission.
According to the FAA inspector who talked to the instructor, while practicing soft-field takeoffs, the student pulled the aircraft into the air prior to attaining enough speed to remain airborne. The aircraft almost immediately banked sharply to the left, and dropped back onto the runway hard enough to be "jolted" back into the air. The takeoff was then continued, followed by an immediate return to inspect for damage.
According to the instructor pilot, when the aircraft, which was configured with a single throw-over control yoke, began lifting off, he commanded the student to "drop the/your nose." The student did not drop the nose enough to avoid the premature lift-off, and the instructor did not attempt to apply forward pressure on the central control pedestal to keep the aircraft from lifting off too early.
