## Probable cause

the student pilot's inadequate compensation for the crosswind condition, and his failure to maintain proper runway alignment.

## Sequence of events

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

- Loss of control - on ground/water, landing - roll
  - weather condition - crosswind (contributing factor)
  - compensation for wind conditions - inadequate, pilot in command (cause)
  - proper alignment - not maintained, pilot in command (cause)
- On ground/water encounter with terrain/water, landing
  - terrain condition - ditch

## Analysis

The student pilot had been cleared for his first unsupervised solo activity by his flight instructor and flight supervisor. The school established a maximum total wind component of 15 knots, and a maximum crosswind component of 5 knots. At approximately 0730, the flight supervisor recalled all student pilots from the practice area due to the wind direction and velocity exceeding the forecast conditions. The tower was in the process of changing runways. Before the runway change occurred, the student pilot requested and had been cleared for a touch-and-go landing on runway 21R. During the landing rollout phase, the student pilot encountered a crosswind, and the aircraft veered off of the runway and into a ditch. The wind was from 150 degrees at 8 knots. There were no mechanical malfunctions noted.

## Factual narrative

On April 9, 1997, at 0755 hours mountain standard time, a Cessna 172N, N8123E, veered off runway 21R and struck a ditch while practicing touch-and-go landings at Ernest A. Love Field, Prescott, Arizona.  The airplane, owned and operated by Embry-Riddle Aeronautical University (ERAU), was substantially damaged.  The student pilot, on a local area solo instructional flight, was not injured.  Visual meteorological conditions prevailed and no flight plan was filed.  The flight originated at 0640.

According to the operator's report the student pilot had been approved by his flight instructor for a maximum total wind component of 15 knots, a maximum crosswind component of 5 knots.  The duty flight supervisor reviewed the student pilot's qualifications and approved him for departure.  The pilot was dispatched during routine operations for his first unsupervised solo activity.

At approximately 0730, the flight supervisor began to observe wind direction and velocity exceeding forecast conditions.  At the same time, Prescott Tower started a runway change.  The flight supervisor subsequently began recalling all student pilots from the practice area.  At this time, the student pilot was returning from the practice area and was preparing for a touch-and-go.

The student pilot reported that after touchdown, the aircraft was rolling off the runway towards the left.  He stated that he applied right rudder in an attempt to bring the plane back onto centerline.  This didn't effect the airplane path as it continued to roll off the runway.  Reported winds were from 150 degrees at 8 knots.

An Federal Aviation Administration (FAA) inspector from the Scottsdale, Arizona, Flight Standards District Office reviewed aircraft logbooks and maintenance entries.  No deficiencies were noted.  The aircraft was inspected and no abnormalities were found.
