## Probable cause

The inadvertent brake activation by the student pilot while practicing touch-and-go landings.

## 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
  - brakes(normal) - inadvertent activation, pilot in command (cause)
  - ground loop/swerve - encountered
- Gear collapsed, landing - roll

## Analysis

On the third touch-and-go landing the student pilot inadvertently applied brake pressure.  He lost control, ground looped the aircraft, and the landing gear collapsed.  No mechanical malfunctions of the brake was noted by the student pilot.

## Factual narrative

On January 13, 1998, at 1520 hours mountain standard time, a Cessna 140, N2496V, ground looped on landing and collapsed the landing gear at the Goodyear, Arizona, airport.  The aircraft sustained substantial damage, and the student pilot was not injured.  Visual meteorological conditions existed for the local solo instructional flight and no flight plan was filed.

The student pilot reported that on his third touch-and-go landing he inadvertently applied brake pressure on landing, lost control, and ground looped the aircraft.  He stated that weather was not a factor.  He also reported that there were no mechanical difficulties with the aircraft.
