The loss of engine power for undetermined reasons.

## 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, emergency descent/landing
- Hard landing, emergency descent/landing
  - terrain condition - ground

## Analysis

The pilot reported that he conducted a preflight and run-up of the amateur-built experimental airplane, and he reported that it was operating normally.  The airplane had climbed to 200 - 300 feet at 90 knots when the engine lost power.  The pilot executed a forced landing to the airport property.  The airplane landed hard and the main landing gear collapsed.  The airplane and engine were inspected but the reason for the loss of power was not determined.
