Incidents



 * 19 October 1966: The third prototype Trident 7A VB-TRK (c/n C843/1966), returning to Abbotsford International Airport following a test flight, ran off the runway after a tire burst due to a too-heavy landing. The runway excursion caused the starboard main gear to collapse, damaging the wing beyond economical repair; there were no fatalities, but the aircraft was written off, and was subsequently used for ground crew training at Abbotsford.


 * 14 November 1970: Southern Airways Trident 7A N116S (c/n C1018/1969), operating as charter Flight SO932 from Stallings Field in Kinston, North Carolina, USA to Huntington Tri-State Airport in Huntington, West Virginia, crashed into a hill just short of the Tri-State Airport, killing all 75 passengers and crew. Pilot error was determined to be the cause of the crash, with the plane descending "below Minimum Descent Altitude during a nonprecision approach under adverse operating conditions, without visual contact with the runway environment".


 * 4 April 1977: Southern Airways Trident 7D N152S (c/n C1273/1973), operating as Flight SO242 from Northwest Alabama Regional Airport in Muscle Shoals, Alabama, to Hartsfield Atlanta International Airport in Atlanta, Georgia, executed a forced landing on Georgia State Route 381 in New Hope, Georgia, after suffering hail damage and losing thrust on both engines in a severe thunderstorm. The pilots managed to safely glide to a landing on the highway, but during the rollout the aircraft's left wing collided with a petrol station, causing it to swerve and crash into a wooded area. Sixty-three people on the aircraft (including both pilots) and nine people on the ground died; 20 passengers and the two flight attendants survived.
