On 25 December 2013, an Airbus A330-300 conducted a stable night non-precision approach at St. Lucia but the crew found that after touchdown, atypical intervention was needed to ensure direction along the runway was maintained and also detected both ‘juddering’ and a more significant rate of deceleration than usual. Considerable impact damage to the lower fuselage and below-floor systems was subsequently discovered. The Investigation concluded that this damage had resulted from impact with water from a diverted river channel which had burst its banks and flooded the touchdown area of the runway to a depth of up to 60 cm.
