Casualties: Fatalities: 0 / Occupants: 34
Component Affected: Nose undercarriage structureNose undercarriage structure
Category: Accident
During a flight, a port wing flap beam fairing experienced the loss of two screws between the inner and middle flaps. Due to a material fracture on the nosewheels during touchdown, the nosewheels and axle broke off, resulting in a landing with the stub of the leg contacting the ground. The aircraft swung to port, stopped clear of the runway, and a small fire was extinguished by airport fire service. The Commission concluded that the accident was caused by a fracture of a part of the nose undercarriage structure under conditions of a landing without flaps.During a flight, a port wing flap beam fairing experienced the loss of two screws between the inner and middle flaps.

Description

During the flight two screws were noticed to be missing from the flap beam fairing between the inner and middle flaps on the port wing. As a precaution it was decided to make a flapless landing at Geneva. The touchdown was smooth, on the mainwheels, but the nosewheels and axle broke off because of a material fracture when the nosewheels touched the runway. The aircraft continued straight down the runway, with the stub of the leg in contact with the ground. When the speed had dropped to about 30 knots, the aircraft swung to port on to a taxiway and stopped just clear of the runway. A small fire in the nosewheel bay was quickly put out by the airport fire service. Conclusions: “The Commission arrived unanimously at the following conclusion : The accident was due to the facture of a part of the nose undercarriage structure during a landing made without flaps, probably subject to the accompanying influence of local weakening of the fractured part.”
