Air Transat Flight 961 was a regularly scheduled service operating between Varadero, Cuba, and Quebec City, Canada, on March 6, 2005. During the flight, the Airbus A310-308 suffered a structural malfunction when its rudder separated mid-air. Nevertheless, the flight crew successfully regained command of the aircraft and executed a safe return to Varadero. By 2020, the Airbus A310-308 model had been retired from active service.
The subsequent investigation identified deficiencies in the manufacturer's inspection methods for the composite rudder, which led to revisions in inspection standards for composite components in aircraft.
Event
Operating with 262 passengers and 9 crew members aboard an Airbus A310-308 registered as C-GPAT—originally delivered to Emirates in 1992 and later acquired by Air Transat in 2002—Flight 961 departed at 2:48 am EST. After reaching cruising altitude, a sudden loud noise at 3:02 am triggered a severe dutch roll motion. The pilots responded by descending and initially considered diverting to Fort Lauderdale; however, Air Transat’s operations center recommended returning to Varadero as the safer alternative. No alerts regarding rudder or yaw damper malfunction appeared on the cockpit instruments. The aircraft touched down safely at 4:19 am. Inspection after landing revealed that the entire rudder had separated from the vertical stabilizer.
Cause
Although much of the cockpit voice and flight data recordings were lost due to the extended duration of the incident, investigators concluded that a probable stress fracture had developed in the tail section unnoticed across multiple flights. The Airbus A310 design does not include a mechanism to arrest such crack propagation.
The Transportation Safety Board of Canada determined that the inspection regime for composite rudders was insufficient, raising concerns about rudder longevity. This event provided critical insights into rudder-related issues affecting Airbus A300-600, A300-600R, and A310 variants, leading to mandatory inspections throughout these fleets.
