Incident Overview

Date: Friday 2 August 1963
Aircraft Type: de Havilland DH-106 Comet 4B
Owner/operator: British European Airways – BEA
Registration Number: G-ARJN
Location: Milano-Linate Airport (LIN) – ÿ Italy
Phase of Flight: Landing
Status: Substantial, repaired
Casualties: Fatalities: 0 / Occupants: 96
Component Affected: Tyres on the port mainwheel and starboard mainwheel.Tyres on the port mainwheel and starboard mainwheel.
Category: Accident
A monitored automatic ILS approach was initiated from London, Italy, but the captain decided to overshoot due to insufficient positioning on the centre line. A subsequent automatic approach was made, and the approach lights were confirmed when the aircraft reached 300 ft. The aircraft remained on the centre line and continued the descent, culminating in the captain taking over control at approximately 250 ft. The runway lights were visible, and the approach was continued by visual reference. The aircraft subsequently ran into reduced visibility and experienced increased deceleration, culminating in tyre failure on the port mainwheel and subsequent fire. The aerodrome fire tenders extinguished the fire, and the aircraft was found with a burst on the port mainwheel and a burst on the starboard mainwheel.A monitored automatic ILS approach was initiated from London, Italy, but the captain decided to overshoot due to insufficient positioning on the centre line.

Description

On arrival from London a monitored automatic ILS approach was made in fog at Milano-Linate Airport, Italy but the captain decided to overshoot because, although the approach lights were seen, the aircraft was not satisfactorily positioned on the centre line. A second monitored automatic approach was then made and the approach lights were seen when the aircraft reached 300 ft. It was on the centre line and the descent was continued. The captain took over the controls at about 250 ft. as the runway lights were seen, continuing the approach by visual reference. The time was some 20 minutes after dawn had broken and landing lights were not used. After the touchdown reverse thrust was immediately applied, followed by braking. Soon after landing the aircraft ran into an area of much reduced visibility and braking was increased. After a swing to port, which was corrected without difficulty, deceleration was pronounced. When the aircraft came to a standstill it was found that the tyres on the port mainwheels had burst and were on fire. The fire was extinguished by the aerodrome fire tenders. It was also found that one tyre on the starboard main undercarriage had burst. A deterioration in runway visual range was observed immediately before the touchdown, but too late to pass to the pilot.
