## Probable cause

The pilot's failure to maintain control of the airplane, while landing.

## 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
  - aircraft control - not maintained, pilot in command (cause)
- Nose over, landing - roll

## Analysis

The pilot/hunting guide reported he was landing his tailwheel converted Cessna 150 airplane at a remote, off-airport site to pick up a hunting party and their game. He said that during the landing roll, he lost control of the airplane, and it subsequently nosed over.

## Factual narrative

On September 22, 1995, about 1700 Alaska daylight time, a tail- wheel converted Cessna 150 airplane, N4430U, sustained substantial damage while landing at an off airport site located approximately 50 miles northeast of Coldfoot, Alaska. The solo commercial certificated pilot was not injured.  The business flight operated in visual meteorological conditions under 14 CFR Part 91 without a flight plan. The purpose of the flight was for the pilot/registered hunting guide to recover game and clients from a remote hunting site.

The pilot stated in a telephone conversation on September 27 with the NTSB investigator-in-charge that while he was landing at the  550' long site, he lost directional control and the airplane flipped upside down. He said that there was no preimpact mechanical problems with the airplane.

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.
