## Probable cause

The pilot's inadvertent stall/mush during a go-around attempt.  A contributing factor was the high density altitude weather condition.

## Sequence of events

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

- Loss of control - in flight, landing - aborted
  - go-around - initiated, pilot in command
  - stall/mush - inadvertent, pilot in command (cause)
  - weather condition - high density altitude (contributing factor)
- In flight collision with terrain/water, go-around (vfr)
  - terrain condition - open field

## Analysis

The pilot said that during a landing attempt, the airspeed got low and he flared a 'little high.'  He applied full power to perform a go-around, but the airplane mushed to the ground.  The impact sequence bent both wings and wrinkled the fuselage.  The weather conditions at the time of the accident were as follows: temperature 77 degrees Fahrenheit; altimeter setting 30.28 inches of mercury; density altitude 10,799 feet (elevation 8,149 feet).

## Factual narrative

On July 25, 2000, approximately 1015 mountain daylight time, a Fudold Avid Magnum, N200UB, was substantially damaged when it impacted terrain during a go-around attempt at Jackson County Airport, Walden, Colorado.  The private pilot and his passenger were not injured.  The airplane was being operated by the pilot under Title 14 CFR Part 91.  Visual meteorological conditions prevailed for the local flight that originated approximately 1 hour 25 minutes before the accident.  No flight plan had been filed.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
