## Probable cause

THE PILOT'S IMPROPER USE OF WING FLAPS AND PREMATURE LIFT-OFF. THE PILOT'S POOR PREFLIGHT PREPARATION WAS A FACTOR.

## Sequence of events

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

- Loss of control - in flight, takeoff - initial climb
  - preflight planning/preparation - poor, pilot in command (contributing factor)
  - lowering of flaps - improper, pilot in command (cause)
  - lift-off - premature, pilot in command (cause)
  - object - vehicle
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PILOT ATTEMPTED A TAKEOFF FROM A ROAD.  DURING THE TAKEOFF ROLL HE INADVERTENTLY LOWERED THE FLAPS FULL DOWN.  WHEN THE AIRPLANE TOPPED A HILL AND WAS IN DANGER OF COLLIDING WITH A FARM TRUCK THE AIRPLANE BECAME AIRBORNE, BUT WAS UNABLE TO CONTINUE FLIGHT AND IMPACTED THE TERRAIN.

## Factual narrative

On September 22, 1994, at 1900 central daylight time, a Cessna 150G, N6685F, owned by Ronald C. Tangsrud of Wildrose, North Dakota, and operated by a private pilot, departed controlled flight and collided with terrain during initial climb while taking off from a road near New Town, North Dakota.  The airplane sustained substantial damage.  The pilot reported no injuries.  The business 14 CFR Part 91 flight was operating in visual meteorological conditions.  No flight plan was on file.  The flight was departing with the intended destination of Wildrose, North Dakota.

The pilot stated that during takeoff roll he intended to deploy ten degrees of flap; however, "... the flaps would not shut off."

The Federal Aviation Administration (FAA) inspector who talked to the pilot and a witness to the accident stated that when the airplane topped a rise in the road and was faced with an imminent collision with a farm truck the airplane became airborne, but was unable to continue flight and impacted the terrain.

The FAA inspector examined the accident airplane, subsequent to the accident paying particular attention to the flap switch.  The switch arrangement in the airplane consisted of a center off with momentary "Up" and momentary "Down" positions.  The inspector stated that the switch worked properly in all positions, the spring tension was good in both directions, and that he could find no mechanical or electrical fault with the switch in any position.

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.
