Introduction Being involved in an aviation accident is a nightmare scenario for all air travellers, crew and pilots. Statistically, air transport is one of the safest means of transport, but at the same time it is also associated with sporadic accidents which, for a variety of reasons, have proven to be extremely terrifying ordeals for all those involved. The causes of these accidents are of various nature and depend on some problems that arise during some phases of the flight process. Main causes of air accidents1. Decent Landing and Landing Accidents Decent Landing and Landing Accidents have been statistically proven to be one of the most common forms of aviation accidents. Ultimately, accounting for approximately 37% of aviation accidents, there are different phases of the descent and landing process and various mechanical problems, as well as a lack of concentration on the part of the pilot, can contribute to an incorrect landing, ultimately resulting in a minor or minor plane crash. fatal accident (Tullo, 2001).2. Human ErrorThe root cause of airline crashes at some point contains an element where a person is unable to perform their duties correctly and accurately. Over 53% of accidents are the result of ignorance or errors on the part of the pilot during the flight. The remaining personnel are responsible for approximately 8% of accidents. The most obvious pilot errors are made during takeoff or landing on the runway. Additionally, errors can occur when maintaining the aircraft off the plane, so the lack of thorough inspection and supervision can lead to complications during the flight. Refueling and loading the aircraft also sometimes create problems (Shapiro, 2001).3. Mechanical FailureMechanical failure accounts for 25% of the aircraft...half of the paper...ff. Some accidents that occur during flight at medium or high altitude are reported. There are numerous reasons for a plane crash, but the main reasons for plane crashes include; human error, mechanical failure, adverse weather conditions and sabotage. To further reduce the number of aviation accidents it is necessary to implement more rigorous measures to evaluate the operability of the aircraft before take-off. Furthermore, better pilot training can also lead to a more preferable outcome in the event of a problem, as the pilot will be better equipped to handle an emergency. References: De Almeida, I. M.
