AIRCRAFT ACCIDENT INVESTIGATIONS IN INDONESIA
An accident or mishap is an unforeseen and unplanned event or circumstance, often with lack of intention or necessity. It usually implies a generally negative outcome which may have been avoided or prevented had circumstances leading up to the accident been recognized, and acted upon, prior to its occurrence (Wikipedia).
There are two categories of aviation mishap defined by the Convention on International Civil Aviation Annex 13. An aviation accident is an occurrence associated with the operation of an aircraft, which takes place between the time any person boards the aircraft with the intention of flight until such time as all such persons have disembarked, where a person is fatally or seriously injured, the aircraft sustains damage or structural failure or the aircraft is missing or is completely inaccessible. An aviation incident is defined as an occurrence, other than an accident, associated with the operation of an aircraft that affects or could affect the safety of operations.
Underlining the necessity to recognize the root cause of an occurrence in order to avoid or prevent any unfortunate circumstances, it is important to investigate each emerging case thoroughly. In Indonesia, this role is carried out by Komite Nasional Keselamatan Transportasi (KNKT) or also known by its international designation as National Transportation Safety Committee (NTSC). The air transport occurrence investigation is performed under ICAO Annex 13, an international guidelines for every investigation agencies, boards, bureaus and committees, to ensure a standard and comprehensive evaluation. The investigation is also conducted in a ‘no blame’ base, focusing more into the contributing factors and how to improve the systems rather than pursuing liability.
One of the elements that almost always involved in an occurrence investigation is the flight recorder. It provides valuable information for investigators along with other source of information as aircraft and occurrence site data, radar and Air Traffic Controller (ATC) data, engineering manuals, operation manuals, maintenance logs, witness interviews and so forth. Therefore, an investigation will never be executed individually but as a team effort, since it involved different fields of expertise.
All occurrences are different and require a particular approach during the course of investigation. This and “Never Jump into Conclusion” should be the foundation of all investigation process.
