## Probable cause

The failure of the pilot under instruction to maintain directional control during the landing roll and the inadequate supervision of the flight instructor, which resulted in a collision with a runway light, overload failure of the wheel axle, and the airplane nosing over inverted.

## 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, copilot/second pilot (cause)
  - supervision - inadequate, pilot in command(cfi) (cause)
- On ground/water collision with object, landing - roll
  - object - runway light
- Nose over, landing - roll
  - landing gear,axle - failure
  - landing gear,axle - overload

## Analysis

During the landing roll, the airplane veered off the runway and contacted a runway light.  After about 50-75 feet of additional landing roll, the left main gear wheel axle broke and the airplane nosed over inverted.

## Factual narrative

On June 15, 2000, at 1115 hours Pacific daylight time, a Cessna 140, N2688N, ran off the runway and nosed over during landing at Hayfork, California.  The flight instructor was not injured, and the private pilot sustained minor injuries.  The airplane, operated by the pilot under instruction, sustained substantial damage.  The local area instructional flight was conducted under the provisions of 14 CFR Part 91.  The pilot did not file a flight plan and did not obtain a weather briefing prior to departure.  Visual meteorological conditions prevailed at the time of the accident.  The flight originated in Eureka, California, at an unknown time.

According to the owner of the airplane, this flight was to be an instructional flight prior to solo for insurance purposes.  He said that they departed Eureka Airport and then went to Kneeland and landed.  They then flew to Hayfork Airport and landed on runway 25.  He stated that upon rollout he got off the left side of the runway a "few feet" and broke a runway light lens.  The light lens hit the fuselage about 6 feet in front of the tail wheel.  He said they continued to rollout about 40 miles per hour for 50-75 feet, when the left main gear axle broke and the airplane nosed over onto it's back.
