Aircraft Accident Investigation is a highly specialized task which should only be undertaken by trained personnel possessing many qualities, not the least important of which are an inquisitive nature, dedication to this kind of work, diligence and patience. The investigator must have a good sound working knowledge of aviation and factors which effect operations as a whole. Technical skill, perseverance and logic are the tools of his / her profession; humility, integrity, and respect for human dignity his guiding rules.

It is not sufficient to nominate as the occasion arises, a person with specialist aviation knowledge as the investigator, for aircraft accident investigation is a specialist task it self. The standard of the investigator assigned to an accident inquiry determines the thoroughness and class of results obtained more than in any other filed of aeronautics, the longer a well-qualified member serves the more expert he / she becomes. Wherever possible, at least one experienced investigator should be assigned to each inquiry so that a continuing thread of experience may maintain the standards of accident investigation and reporting.

It is desirable that accident investigators have, as a foundation on which to develop their skills, a professional pilot’s background, an aeronautical engineering qualification or, as appropriate, experience in specialized areas of aviation such as operations, air traffic control, meteorology, aerodynamic, design, etc. 

In order to discharge effectively their duties, it is essential that aircraft accident investigators are provided with suitable statutory powers which should, nonetheless, be used with discretion. The investigator will come in contact with many kinds of people the majority of whom recognize than investigator’s status and will more often than not feel obliged to offer all assistance they can without the investigator reminding them of the official powers which are vested in him / her. He / She will also encounter members of the general public who are less well acquainted with his / her activity and who may show reticence to be forthcoming with evidence, stemming from a natural desire not to become involved. It may, in these latter circumstances; it may necessary for the investigator to explain his / her function and to elicit their willing co-operation. 

When called to the scene of the accident, the investigator should endeavor to arrive as soon as possible; in his / her dealings with witnesses and other people concerned in the accident, he / she should be prompt in attending appointments and correct in his / her manner, regardless of how he / she may feel personally. Above all, the investigator must be accurate and factual; he / she must observe, interpret and record clearly and accurately at all times, because his / her record of what is seen, heard and done, may well prove to be the only record available, the analysis of which may have far-reaching effects on individual people, aircraft, equipment and aviation safety as a whole.
