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. Nine continuous days of heavy rain had softened the grass field, and the runway excursion caused the starboard main gear to collapse after getting mired in the mud, 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.
