## Probable cause

FAILURE OF THE PILOT TO MAINTAIN CONTROL OF THE AIRCRAFT, WHILE FLYING IT WITH A LATERALLY IMBALANCED CONDITION. FACTORS RELATED TO THE ACCIDENT WERE:  THE PILOT'S LACK OF FLYING EXPERIENCE, AND HIS LACK OF FAMILIARITY WITH THIS AIRCRAFT.

## 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
  - aircraft weight and balance - misjudged, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (contributing factor)
  - aircraft control - not possible, pilot in command (cause)
  - lack of total experience in type of aircraft, pilot in command (contributing factor)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

THE PRIVATE PILOT WAS CONDUCTING THE INITIAL FLIGHT IN THE AMATEUR BUILT EXPERIMENTAL AIRCRAFT. THE AIRCRAFT CONTAINED 12 GALLONS OF FUEL; ALL IN THE LEFT WING. DURING THE INITIAL CLIMB, THE AIRCRAFT ENCOUNTERED AN UNCOMMANDED ROLL TO THE LEFT, WHICH THE PILOT WAS UNABLE TO ARREST WITH CONTROL INPUTS. THE AIRCRAFT DESCENDED AND IMPACTED THE TERRAIN OFF THE LEFT SIDE OF THE RUNWAY.
