## Probable cause

A total loss of engine power during the initial climb for undetermined reasons.

## Sequence of events

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

- Loss of engine power(total) - nonmechanical, takeoff - initial climb
  - reason for occurrence undetermined (cause)
- Forced landing, descent - emergency
- In flight collision with terrain/water, emergency landing
  - terrain condition - ground

## Analysis

During the initial climb, about 50 feet agl, the engine began to slowly lose power.  The pilot attempted to fly a traffic pattern back to the runway, but on a crosswind leg, the engine lost all power.  He then performed a forced landing to a parking lot and impacted terrain.  The airplane was powered by a Le Rhone Type J, nine-cylinder rotary engine; which was manufactured about 1914.  Examination of the wreckage by an FAA inspector did not reveal pre-impact mechanical malfunctions.  However, the inspector was unable to rotate the propeller due to cylinder impact damage.  Fuel remained in the airplane, and was absent of debris.

## Factual narrative

On June 4, 2003, about 1300 eastern daylight time, a homebuilt Avro-504K, N4929, was substantially damaged during a forced landing, following a loss of engine power after takeoff from Old Rhinebeck Aerodrome (NY94), Rhinebeck, New York.  The certificated commercial pilot sustained minor injuries.  Visual meteorological conditions prevailed, and no flight plan was filed for the local personal flight conducted under 14 CFR Part 91.

The pilot reported that during the initial climb from the north runway, about 50 feet agl, the engine began to slowly lose power.  The pilot attempted to fly a traffic pattern back to the runway, but on a crosswind leg, the engine lost all power.  He then performed a forced landing to a parking lot.  During the landing, the left wing and engine struck the ground.  The pilot further stated that the airplane was powered by a Le Rhone Type J, nine-cylinder rotary engine.  The engine was manufactured about 1914.

An initial examination of the wreckage by a Federal Aviation Administration (FAA) inspector did not reveal pre-impact mechanical malfunctions.  However, the inspector was unable to rotate the propeller due to cylinder impact damage.  He recovered a fuel sample of the 100LL/Mogas combination from the wreckage.  The fuel was clear and absent of visible contamination.  The inspector added that two mixture controls were used to control rpm, but there was no placarded data for the position of the controls.
