Location: Phoenix, AZ
Accident Number: GAA19CA542
Date & Time: 09/12/2019, 0630 MST
Registration: N796WW
Aircraft: Cessna 172
Aircraft Damage: Substantial
Defining Event: Loss of control in flight
Injuries: 1 None
Flight Conducted Under: Part 91: General Aviation - Instructional 

The solo student pilot reported that, during takeoff, the airplane drifted left off the runway. Concerned the takeoff was unsafe, he decided to abort the takeoff and landed the airplane in the gravel field adjacent to the runway. He used the brakes to slow down and attempted to maneuver the airplane back on the runway. The right main landing gear impacted a runway sign, and the airplane veered right. The airplane continued to veer right, crossed the runway, and impacted a second runway sign. The airplane came to rest in a gravel field.

The airplane sustained substantial damage to the fuselage aft of the nose wheel and the right horizontal stabilizer.

The student pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

The airport's automated weather observation station reported that, about the time of the accident, the wind was calm. The airplane was departing from runway 07.
