Broomfield, CO, US

On September 20, 1997, a Mooney M20M (registration N9140Z) was involved in an aviation accident near Broomfield, CO. Investigators recorded the probable cause as: The pilot's flaring of the airplane prematurely at a low airspeed that resulted in a hard landing, and an inadvertent stall during the attempted go-around and subsequent loss of control. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot experienced a hard landing with two bounces, then applied full power to abort. The airplane stalled, landed on the nose gear, and veered off the runway. Normal approach speed for the aircraft type is 75 knots with full flaps.

Event Details

The pilot reported that during the landing approach, the airspeed was between 80 and 90 knots. Full flaps were selected before the speed brakes were deployed. The airplane touched down hard and bounced twice. In an attempt to abort the landing, the pilot applied full power. Subsequently, the airplane stalled, contacted the runway on the nose gear, and veered off the runway surface.

Aircraft Performance Information

According to the manufacturer, Mooney Aircraft Corporation, the normal approach speed with full flaps (33 degrees) deployed is 75 knots. The speed brakes may also be used during the landing approach.

Sequence of Events

The pilot initiated the landing with flaps fully extended and then activated the speed brakes. The landing was firm, causing two bounces. The pilot then elected to go around by adding full engine power. However, the airplane stalled, resulting in a nose-first touchdown and a subsequent departure from the runway.
