## Probable cause

THE LOSS OF ENGINE POWER FOR UNDETERMINED REASONS, AND THE PILOT'S FAILURE TO MAINTAIN AIRSPEED, WHICH RESULTED IN AN INADVERTENT STALL AT TOO LOW OF AN ALTITUDE TO EFFECT RECOVERY.

## Sequence of events

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

- Loss of engine power, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- Loss of control - in flight, descent - emergency
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- In flight collision with terrain/water, descent - uncontrolled

## Analysis

DURING THE INITIAL CLIMB AFTER TAKE OFF, WITNESSES NOTED THAT THE ENGINE ON THE MOTORIZED GLIDER HAD QUIT OR WAS SPUTTERING. THE GLIDER PASSED OVER TWO ADDITIONAL WITNESSES, JUST ABOVE THE TREE TOPS, WITH THE PROPELLER WINDMILLING. THE ENGINE WAS AGAIN HEARD BUT WAS DESCRIBED AS TOO LOUD & RACING. AFTERWARDS THE SOUND OF AN IMPACT WAS HEARD. AN EXAMINATION OF THE ENGINE FAILED TO REVEAL AN EXPLANATION FOR THE LOSS OF ENGINE POWER. THE FLIGHT CONTROLS WERE FOUND INTACT & FUNCTIONAL. AN EXAMINATION OF THE ACCIDENT SITE INDICATED THAT THE GLIDER HAD IMPACTED IN A NEARLY VERTICAL NOSE DOWN ATTITUDE. IT CRASHED IN AN OPEN FIELD JUST AFTER OVERFLYING THE EDGE OF THE TREE LINE WHICH BORDERED THE OPEN FIELD.

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.
