Incident Overview
At the conclusion of a business flight, the pilot extended the landing gear and observed that the left main landing gear indicated it was not down and locked. The pilot then activated the emergency landing gear extension, but the indicator still showed that the gear was not down.
Engine Shutdown and Impact
While on final approach, the pilot shut down the engine, anticipating that if the landing gear collapsed, damage to the engine might be minimized. However, when the engine was shut off, the aircraft's sink rate increased. The pilot attempted to restart the engine but was unsuccessful. The aircraft subsequently collided with terrain approximately half a mile from the airport.
Investigation
The investigation did not determine whether the landing gear was down and locked at the time of the collision.
