## Probable cause

the pilot's failure to maintain directional control.

## 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
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - encountered, pilot in command
- Main gear collapsed, landing - roll
  - landing gear,main gear - overload
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - ground

## Analysis

The airplane ground looped off the runway and collapsed the right main gear during a touch-and-go.  The pilot reported that upon touchdown, he lost directional control and the airplane veered left and then ground looped off the runway.  The right wing tip was damaged upon contact with the ground, and the right main landing gear collapsed.  The pilot reported that the airplane had no mechanical failures or malfunctions prior to the loss of control.

## Factual narrative

On March 22, 2005, about 1630 mountain standard time, a Piper PA-18-150, N4101E, ground looped during an attempted touch-and-go landing at Chandler Municipal Airport, Chandler, Arizona.  Chandler Air Service, Inc., was operating the airplane under the provisions of 14 CFR Part 91.  The private pilot, the sole occupant, was not injured; the airplane sustained minor damage.  The local personal flight departed Chandler about 1615.  Visual meteorological conditions prevailed, and no flight plan had been filed.  The approximate global positioning system (GPS) coordinates of the primary wreckage were 33 degrees 16 minutes north latitude and 111 degrees 48 minutes west longitude.

The pilot was conducting his second touch-and-go landing.  Upon touching down, he stated that he lost control and the airplane veered to the left and spun around 180 degrees.  The plane came to rest off the runway on the right wing tip with the right main gear collapsed.

The pilot reported that the airplane had no mechanical failures or malfunctions prior to the loss of control.
