Analysis

The aircraft was being flown on a local test flight following a new engine installation. This was only the second flight for this home built aircraft. During climb-out, the engine lost power and there was insufficient altitude for a normal runway landing. The aircraft was landed within the airport boundaries, but received hull damage on rough terrain. The power loss was traced to a malfunction of the propeller governor. According to the pilot, this was caused by a fouled cable.
