## Probable cause

the student pilot's poor short field takeoff procedure and excessive nose rotation resulted in an inadvertent stall.  A factor is the student pilot's lack of total experience.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Loss of control - in flight, takeoff
  - short field takeoff/procedure - poor, pilot in command (cause)
  - lack of total experience, pilot in command (contributing factor)
  - rotation - excessive, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE STUDENT PILOT WAS PRACTICING FULL-STOP LANDINGS AND TAKEOFFS. ON THE FOURTH TAKEOFF, THE STUDENT PILOT EXECUTED A SHORT FIELD TAKEOFF.  SHORTLY AFTER LIFT-OFF, THE STALL WARNING HORN SOUNDED AND THE AIRPLANE STALLED.  THE AIRPLANE STRUCK THE GROUND IN A NOSE- AND LEFT WING-DOWN ATTITUDE.  THE WRECKAGE EXAMINATION DISCLOSED NO EVIDENCE OF ANY PREEXISTING MALFUNCTIONS OR FAILURES.

## Factual narrative

On January 31, 1995, at 1510 hours mountain standard time, a Beech F33A, N6635C, lost control and crashed shortly after lifting off runway 6L at Ryan Field, Tucson, Arizona.  The pilot was conducting a local visual flight rules solo instructional flight.  The airplane, registered to and operated by Air Transport Training International, Inc., Tucson, Arizona, sustained substantial damage.  The student pilot was not injured. Visual meteorological conditions prevailed.  The flight originated at Ryan Field at 1320 hours.

The operator told National Transportation Safety Board investigators in a telephone interview conducted on February 2, 1995, that the student pilot had flown to the practice area before returning to Ryan Field.  The pilot returned to the airport and executed five full-stop landings and takeoffs.

On the last takeoff, the student pilot was executing a short field departure.  The operator said the student pilot "overrotated" and the airplane stalled shortly after becoming airborne.  The airplane initially struck the ground in a nose- and left wing-down attitude.

The pilot said in the aircraft accident report that he initially flew to the practice area.  After practicing some maneuvers, he returned to Ryan Field and made three full-stop landings.  On the fourth takeoff, he executed a short field takeoff.  Shortly after raising the airplane nose, the stall warning horn sounded; one second later, the airplane struck the ground.  The pilot reported no mechanical malfunctions.
