The Hawker Siddeley HS-125-600A crashed into a residential area near McLean, Virginia. The corporate aircraft had departed Washington National Airport 4 minutes earlier and was en route to Birmingham, Alabama. After a flight crew member reported that the aircraft was climbing through 9,300 feet, monitoring radar stations lost continuous reception of the aircraft's primary and secondary radar target information. Shortly thereafter, ground witnesses saw an explosion in the sky followed by the wreckage of the aircraft falling to the ground. The sky was overcast and light rain was falling. The four persons aboard were killed and the aircraft was destroyed. One residence and two automobiles were destroyed by impact and fire, and several other homes were damaged by falling debris.

PROBABLE CAUSE: "A failure or malfunction of an undetermined nature in the pilot's attitude indicating system which led to a loss of control and overstress of the aircraft structure."
