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

- Loss of control - on ground/water, landing
  - directional control - not maintained, pilot in command (cause)
  - proper alignment - not maintained, pilot in command (cause)
- On ground/water collision with object, landing
  - object - airport sign/marker

## Analysis

The student pilot, who was on her first supervised solo, was attempting to line up for landing on runway 11R. The wind was from 190 degrees at 7 knots. The student said the airplane was lined up too far to the left side of the runway, and the left main landing gear went off the pavement following touchdown. The airplane subsequently struck a taxiway sign. The pilot had a total of 21 hours to total flight experience, all in the accident aircraft.
