## Probable cause

AN INADVERTENT STALL.  A FACTOR 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 - in flight, takeoff - initial climb
  - stall - inadvertent, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled
  - terrain condition - open field

## Analysis

THE PILOT WAS PLANNING TO PURCHASE THE HOMEBUILT AIRPLANE.  THE OWNER SAID HE GAVE THE PILOT PERMISSION TO TAXI THE AIRPLANE AROUND THE RAMP, BUT DID NOT GIVE HIM PERMISSION TO FLY.  THE AIRPLANE WAS SEEN TO TAKE OFF AND ATTAIN A NOSE HIGH ATTITUDE.  ONE WITNESS SAID THE AIRPLANE WAS FLYING 'SLOWLY' AND IT APPEARED THE PILOT WAS NOT 'IN FULL LATERAL CONTROL.' ANOTHER WITNESS SAID IT APPEARED THE PILOT WAS MAKING 'A LOT OF SMALL CONTROL ADJUSTMENTS, LIKE HE WAS BUSY KEEPING IT WHERE HE WANTED IT, BUT IT WAS UNDER CONTROL.'  THE FIRST WITNESS SAID THE AIRPLANE DID 'A CLASSIC DEPARTURE STALL,' WENT INVERTED, AND ENTERED A FLAT SPIN.  ANOTHER WITNESS SAW THE AIRPLANE SPIN TO THE GROUND.  TWO OTHER WITNESSES REPORTED THAT THE AIRPLANE NOSED DOWN TO IMPACT. NO AIRFRAME, ENGINE, PROPELLER, OR FLIGHT CONTROL DISCREPANCIES WERE NOTED.
