Accident Overview
On 22 April 2002, a Cessna 402B aircraft registered as ZS-OLI was involved in an accident at Lanseria Airport (FALA). The flight originated from FASP in Botswana with Lanseria as the intended destination. The aircraft had one pilot and four passengers on board. No injuries were reported.
Events Leading to Accident
The pilot encountered an electrical failure during the return flight. He used the aircraft's emergency extension system to manually lower the landing gear. However, during the landing on Runway 06L at FALA, the undercarriage collapsed.
Damage and Injuries
The aircraft sustained damage to the lower fuselage, propeller, and undercarriage. There were no injuries to the pilot or passengers.
Probable Cause
The investigation could not determine why the undercarriage failed to lock down despite the use of the emergency extension system. The electrical failure that prompted the manual gear extension was traced to a faulty right-hand starter relay.
