## Probable cause

The pilot's failure to maintain proper airspeed resulting in the inadvertent stall during the go-around.  The overload failure of the left main landing gear was a contributing factor.

## Sequence of events

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

- Loss of control - in flight, go-around (vfr)
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, go-around (vfr)
  - terrain condition - ground
  - landing gear,main gear - overload (contributing factor)

## Analysis

The airplane was damaged during an attempted go-around.  The pilot reported that during the go-around, the airplane stalled.  The airplane subsequently struck the ground, the left landing gear collapsed and the airplane nosed over.  The pilot reported no mechanical difficulties.

## Factual narrative

On June 30, 2004, about 1230 central daylight time, an amateur-built Peck Vans RV-4, N43MP, piloted by a private pilot, was substantially damaged during an attempted go-around from runway 27 (2,800 feet by 200 feet, turf), at the Palmyra Municipal Airport, Palmyra, Wisconsin.  The airplane struck the ground, the left landing gear failed and the airplane nosed over.  The pilot and his passenger were not injured.  The 14 CFR Part 91 personal flight was operating in visual meteorological conditions without a flight plan.  The flight originated from Springfield Illinois about 1100.

In a written report, the pilot stated that the wind direction was variable and that his ground speed appeared to be too fast.  He stated that he elected to perform a go-around and stalled.  He listed no mechanical deficiencies.
