## Probable cause

The pilot's failure to maintain control of the airplane during an attempted go-around, which resulted in a hard landing.  Also causal was 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 - in flight, go-around (vfr)
  - go-around - attempted, pilot in command
  - aircraft control - not maintained, pilot in command (cause)
- Hard landing, descent - uncontrolled
- Loss of control - on ground/water, landing
  - directional control - not maintained, pilot in command
- Nose gear collapsed, landing - roll

## Analysis

The private pilot attempted a go-around while on final approach, but lost control of the airplane and landed hard.  The airplane ran off the side of the runway, and the nose gear collapsed, damaging the firewall.

## Factual narrative

On August 11, 2003, about 1830 Pacific daylight time, a Cessna 150, N8515J, made a hard landing at Angwin-Parrett Field, Angwin, California.  Alliance Mission Services was operating the airplane under the provisions of 14 CFR Part 91.  The private pilot, the sole occupant, was not injured; the airplane sustained substantial damage.  The personal local flight departed Angwin at an unknown time.  Visual meteorological conditions prevailed, and no flight plan had been filed.

According to the Federal Aviation Administration (FAA) inspector, the pilot stated that he extended the flaps 20-degrees.  The approach did not look right so the pilot attempted a go-around.  During the go-around attempt, the pilot lost directional control of the airplane, it touched down hard, and then rolled off of the runway.  The nose gear folded under the airplane, resulting in damage to the firewall.

The National Transportation Safety Board investigator-in-charge made repeated requests to the pilot for the completion of NTSB Form 6120.1/2.  However, he did not respond.

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.
