Incident at Lethbridge, AB


1999-06-25: Inbound to Lethbridge, the pilot of C-GTUW, an Ayres S2-R, requested a priority landing, advising he thought he had a "blown jug". The aircraft landed without incident. The spray pump appeared to be touching the ground when taxiing in. OPI - Maintenance and Manufacturing UPDATE M. & M. reported that one of four blades on the fan that drives the spray pump departed, setting up a vibration that the pilot mistook for an engine-related problem. Before the fan and pump stopped rotating, the vibration caused them to jump free of the attach bracket. They remained with the aircraft, held in place by the hoses from the hopper and to the spray booms. The aircraft landed uneventfully but because the fan and pump were hanging lower than normal, more blades on the fan were damaged. The fan and pump were reattached to the aircraft, the blades replaced and the aircraft returned to work. West Wind's PRM and the DOM of the contract AMO are collaborating on submission of an SDR.
