ST Charles, MO, US

On October 20, 1997, a Mooney M20C (registration N9449V) was involved in an aviation accident near ST Charles, MO. Investigators recorded the probable cause as: failure of the alternator's front bearing, depletion of battery power, and failure of the emergency landing gear extension handcrank to engage during the pilot's attempt to perform the emergency procedure. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.

A pilot reported jump-starting the aircraft before departure, then experienced radio loss, empty fuel gauges, and landing gear extension failure. After attempting emergency procedures and a low pass, the aircraft landed on its belly. Post-accident inspection revealed a broken alternator bearing and intermittent manual gear extension engagement.

Incident Overview

According to the pilot's account, the aircraft required a 'jump start' at the departure airport prior to the flight. Shortly after takeoff, the pilot lost radio communications. Later in the flight, both fuel gauges indicated empty. The pilot decided to land at a closer airport than originally planned.

Landing Gear Failure

Approaching the airport, the pilot attempted to extend the landing gear but nothing happened. After flying north of the airport, the pilot carried out the emergency landing gear extension procedure. Returning to the airport, the pilot executed a low pass over the runway in the hope that someone would see the aircraft and signal a 'wave off' if the gear was not down. Another landing attempt was made but the pilot had to perform a go-around due to other traffic in the pattern.

Final Approach and Landing

On the final landing attempt, the pilot reduced airspeed and established a straight-in approach. The aircraft touched down on its belly and slid to a stop on the runway.

Post-Accident Examination

Examination of the aircraft's alternator revealed that the front bearing was broken. Testing of the manual gear extension system showed that the handcrank would not engage every time the handcrank engage lever was placed in the forward position.
