Probable cause

The dual student's premature rotation and failure to attain/maintain an adequate airspeed, which lead to a stall/mush and loss of control in-flight, and the flight instructor's inadequate supervision of the flight. A factor in this accident was the flight instructor's lack of total experience as an instructor.

Analysis

The flight was a dual instructional flight with an 11-hour primary student, who was making the takeoff. The flight instructor reported that the student rotated at 50 knots. After they accelerated to 60 knots, the airplane began a roll to the right and aileron control was lost. He stated that the airplane began to sink at approximately 30 to 40 feet above ground level. The flight instructor added full power, but the airplane impacted the ground on the wheels and slid into two parked aircraft, a truck, and other ground structures. The aircraft was examined by an FAA airworthiness inspector and no discrepancies were found with the aircraft or control system. The CFI, who obtained his flight instructor certificate 2 months prior to the accident, had a total of 33 hours as a flight instructor, and 290 total hours.

Factual narrative

On June 24, 1997, at 0904 hours mountain standard time, a Cessna 152, N96736, slid into two parked, unoccupied general aviation aircraft, a truck, and a support beam of a covered tie down area following an in-flight loss of control immediately after takeoff from Deer Valley Airport, Phoenix, Arizona. The aircraft sustained substantial damage. The certified flight instructor and the dual student were not injured. The aircraft was being operated as a local area training flight when the accident occurred. Visual meteorological conditions prevailed at the time.

Review of the pilot accident report revealed that the CFI had 33.3 hours as a flight instructor, and 290.8 hours total time. Additionally, he had logged 28.6 hours in the preceding 30 days. The dual student had 11.4 hours of total time.

The flight instructor was interviewed by an airworthiness inspector from the Scottsdale, Arizona, Flight Standards District Office. The flight instructor told the FAA inspector that the student pilot was performing the takeoff and rotated at 50 knots. After they accelerated to 60 knots, the airplane began a roll to the right and aileron control was lost. He stated that the airplane began to sink at approximately 30 to 40 feet above ground level. The flight instructor added full power, but the airplane impacted the ground on the wheels and slid into the parked aircraft and other objects.

The aircraft was examined by the FAA airworthiness inspector. No discrepancies were found with the aircraft or control system.
