On 20 September 2011, a Cessna Aircraft 550 Citation II aircraft, registered VH-INT, was involved in a ground towing accident when a Fokker F100 under tow collided with the tail of the parked Citation. The collision resulted in damage to the left elevator, rudder and rudder trim control surfaces that necessitated the Citation undergoing repairs.
On 06 December 2011, while conducting a post-maintenance flight, the crew experienced control problems. The resulting post-flight inspection found several maintenance procedural omissions and rigging inconsistencies.
A review of the maintenance system and processes for return to flight and the acceptance flight versus training flight protocols was conducted respectively by both the maintenance and operator organisations and corrective actions taken.
