## Probable cause

The pilot's failure to lower the landing gear during landing.

## Sequence of events

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

- Wheels up landing, landing - flare/touchdown
  - wheels up landing - inadvertent, pilot in command (cause)

## Analysis

The pilot performed one approach to the runway, and then executed a go-around "due to traffic."  He raised the landing gear during the go-around and continued in the traffic pattern for another landing.  During the second landing attempt, the pilot "neglected to lower the landing gear," and the underside of the airplane contacted the ground.  The pilot reported no mechanical deficiencies with the airplane, and an examination of the airplane by a Federal Aviation Administration (FAA) inspector also revealed no deficiencies.
