Circumstances:
On a leg from Jacksonville to Miami, the crew encountered technical problems and decided to divert to Orlando-Herndon Airport. While on a night approach, the airplane became uncontrollable and crashed onto a house located short of runway threshold. The aircraft was destroyed and all three occupants were killed while no one on the ground was injured.
Probable cause:
It was determined that the loss of control on final was the consequence of an insufficient speed as the pilot failed to maintain flying speed. A failure of a fuel pump forced the crew to modify his route and this was the result of a faulty maintenance and servicing.
