During the process of climbing, the pressure in the cabin decreases continuously. The aircraft then departs Larnaca International Airport at 0907hrs with the pressurization system on “Manual” and with an open aft outflow valve. The aircraft was then back to service, however the flight crews were not able to realize the wrong setting with the pressurization system status on three separate occasions: pre-flight, after-start and the after-take-off checks. After the inspection was done, the engineer did not reset the pressurization system back to “Auto”. In order to conduct the check without requiring the aircraft’s engine, the pressurization system was set to “Manual”. Hence, the ground engineer conducted a thorough inspection which lead him to execute a pressurization leak check. So, the aircraft arrived on Larnaca from London earlier that day, and the previous flight crew had reported a frozen door seal and unusual noises coming from the right aft service door. Hence, resulting the pilots leaving the aircraft flying on autopilot mode until the fuel was fully consumed causing the aircraft to descend into the ground. Initially, all the 121 passengers and crew were incapacitated due to loss of cabin pressurization. Unfortunately, the flight has crashed at 1204hrs and killed all 121 passengers and crew on board.
Hence, stating all significant cause of flight accidents is vital and necessary.īack then on 14 August 2005 at 0900hrs, flight Helios Airways 522, was a scheduled Boeing 737-300 carrying 121 passengers and crew from Larnaca, Cyprus, to Athens, Greece. One of the major contributing factor to flight safety is human error with an approximate of 80 percent, the rest of the 20 percent are due to machine failures. However, with all these safety regulations and practices being put to place, there are still accidents happening. In addition, IATA will always work with airlines and its industry partners to implement best practices to assure safety. This is because safety is always the top priority. Continuous adjustments and amendments are always being made so as to achieve higher standard of safety performance at all time. Air traveling may be frightening to some however, it is the safest mode of transportation with a rate of 0.07 deaths per one billion passenger miles.
