A Challenger 601 corporate jet suffered a runway excursion after landing at Nassau-Lynden Pindling International Airport, Bahamas. According to the pilot, the flight was uneventful. The pilot stated that, while on final approach to runway 14, while at approximately 300 ft., he noticed an increase in airspeed of approximately 10 knots, as a result he increased power. The pilot further stated that just prior to touchdown, there was another variance in airspeed with no power setting adjustments, as a result of these variations, the airplane “slammed on to the runway.” The aircraft bounced several times becoming airborne momentarily each time. The aircraft eventually veered off the runway to the left side where the nose gear subsequently collapsed during the excursion sequence. The aircraft received damages to the nose cone, nose undercarriage and left main landing gear. There were no injuries reported. Convective activities including thunderstorms and rain showers were present in the vicinity of the aerodrome at the time of landing, which may have played a role in this accident.
