History of Flight
The Boeing 777-200, registered 9V-SRG, was operating a scheduled passenger flight from Brisbane, Australia to Singapore. The incident occurred during landing at Singapore Changi Airport at 2035 hours local time on 24 January 2004. The first officer was the pilot flying.
Weather information broadcast by ATIS indicated rain over the airfield with medium braking action on Runway 02L, wind calm, and visibility 6 km. A later update reported no change. During descent, the crew noted heavy rain on weather radar and obtained a deviation. The control tower advised of rain, strong low-level windshear, and medium to poor braking action reported by a preceding arrival. At about 1,800 ft, the tower advised strong crosswind but no windshear reported by the preceding aircraft. The pilot flying initially planned an automatic landing but, after sighting the runway at about 600 ft, requested manual landing. The pilot-in-command agreed, and the autopilot was disengaged at about 520 ft.
To counter crosswind, the pilot flying used cross-control technique. The aircraft maintained glideslope with descent rate about 750 ft/min and indicated airspeed about 135 knots (Vref about 128 knots). Frequent aileron and rudder adjustments were made to stay on localizer. At about 200 ft, the aircraft began deviating right of localizer with right wing low. Corrective actions followed. At touchdown, the aircraft was about 4 m left of runway centreline, with left wing low and firm touchdown at 1.6 g. The crew reported the aircraft skidded left on touchdown.
Runway Excursion
The left main landing gear departed the paved surface for about six seconds. Wheel tracks on the soft grass verge extended about 360 m, with maximum displacement of about 6.2 m from the runway edge. The pilot-in-command took over with full right rudder and brought the aircraft back onto the runway. Antiskid system fault messages appeared, likely due to damage from the excursion.
Damage to Aircraft and Runway
The aircraft sustained minor damage: forward and aft junction boxes under the left landing gear were damaged and separated; all six left main landing gear tyres showed rubber reversion, with tyres 1, 2, and 5 deflated; two wing-to-body fairing panels aft of the wheel well were damaged; a body fairing had a crack about 45 cm; and the left horizontal stabilizer leading edge had a dent about 10 cm by 8 cm. Metal and fibreglass pieces were found on the runway and grass verge. Five runway edge lights along the western side of Runway 02L were damaged. The runway surface was not damaged.
Injuries and Occupants
No injuries occurred. All 269 persons on board disembarked normally via the aerobridge after the aircraft taxied to the gate.
Aircraft Information
The aircraft was a Boeing 777-200, registration 9V-SRG, equipped with two Rolls-Royce Trent 800 engines. It was on a public transport passenger flight.
