During the descent into Farnborough Airport the majority of the right engine upper cowling detached, damaging the leading edges of the vertical and horizontal stabilisers. The investigation concluded that the cowling probably detached because a number of the fasteners had not been secured during maintenance.

The aircraft had departed Göteborg City Airport, Sweden, bound for Farnborough, Hampshire. During the descent, at approximately FL200, there was a sudden bang and the aircraft started to vibrate. The crew reduced speed and disengaged the autopilot; the engine parameters were normal and the aircraft remained in trim. They were concerned that something at the rear of the aircraft was damaged but nothing untoward could be seen through the cabin windows. They configured the aircraft for landing and decided not to use
thrust reverse. The landing was uneventful.

The aircraft was recovered to a local maintenance organisation where the majority of the right engine upper cowling was observed to be missing. Damage on the leading edges of the vertical and horizontal stabilisers was consistent with them being struck by debris.
