## Probable cause

The pilot's failure to maintain directional control during the landing. A factor in the accident was the pilot's lack of familiarity with the airplane.

## 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
  - directional control - not maintained, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (contributing factor)
  - ground loop/swerve - inadvertent, pilot in command

## Analysis

The pilot was landing the tailwheel, tundra tire equipped airplane on an asphalt runway.  The pilot planned to perform a wheel landing.  During the landing roll, the airplane ground looped and departed the right side of the runway.  The airplane received damage to the left wing spars, left aileron, the left horizontal stabilizer, and the left elevator. The pilot indicted he had accrued a total of 3 hours in the accident airplane make and model.

## Factual narrative

On September 16, 1997, about 1330 Alaska daylight time, a tailwheel, tundra tire equipped, Piper PA-22, N5840Z, crashed during landing at the Northway Airport, Northway, Alaska.  The airplane was being operated as a visual flight rules (VFR) cross-country personal flight, when the accident occurred.  The airplane, operated by the pilot, sustained substantial damage.  The certificated airline transport pilot, and the sole passenger, were not injured.  Visual meteorological conditions prevailed.  The flight originated at Merrill Field, Anchorage, Alaska, at 1030.

During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC), on September 20, 1997, at 0930, the pilot reported he was landing on an asphalt covered runway, runway 04, at the Northway Airport.  The pilot planned to perform a wheel landing.  During the landing roll, the airplane ground looped and departed the right side of the runway.  The airplane received damage to the left wing spars, left aileron, the left horizontal stabilizer, and the left elevator.

In the pilot/operator report (NTSB form 6120.1/2) submitted by the pilot, he indicated the wind conditions were from 010 degrees at 3 knots.  The pilot also indicted he had accrued a total of 3 hours in the accident airplane make and model.

Probable cause: The pilot's selection of unsuitable terrain for landing, which resulted in a nose over. A factor contributing to the accident was water on the surface of the ice-covered lake.
