Just this past weekend we witness news report of an Caribbean Airlines Boeing 737 crashed after going off the runway. Miraculously there were no fatal injuries. The B-737 took off from New York's JFK then flew to Guyana's Cheddi Jagan International Airport when the accident happend on landing. The weather conditions at the time was wet slick runways & night. So, you probaby wondering what would cause such a accident in the first place. First, let me mention in most runway overshooting accidents people usually survive. These types of accidents happend when the pilots allowed any outside indicators to reduce their margin of safety. I know at my company we teach pilots to guard against outside risk factors. The risk factors in these types of accidents are always the same. For example , some factors are short runways, wet or ice slick surfaces, night time, crew fatigue, landing too fast and the biggest factor is landing in a tailwind. Pilots always want to land in the direction of the wind (headwind) because it acts as resistance to help slow down an airplane. Most airlines are allowed to land in a tailwind & it's safe to do so but, requires common sense. For example, you would not want to land in a tailwind on a short runway at night with a wet surface. However, landing in a tailwind on a 10,000 feet runway is plenty of distance to stop even with wet surfaces. Most aircraft also have a 10 knot limitation on landing with a tailwind, and most pilots I know place an even greater restriction on it such as 5 knots. In the situation with the Caribbean Airlines accident another possible factor is early reports that the crew forgot to deploy all their flaps. If this is true they would've came down to fast making the situation worst. Their is a saying in aviation, " Safety is no accident, it must be practice".
