ICAO supports the internationally-recognized approach whereby a completed accident investigation will officially determine the causes and contributing factors of the accident, and concurrently provide safety recommendations on appropriate preventative measures to avoid recurrences, as well as guidelines for future consideration by ICAO, States and airlines.
ICAO has developed international standards and recommended practices on the security of flight crew compartments which are presently contained in the following Annexes to the Convention on International Civil Aviation (Chicago Convention):
Annex 6—Operation of Aircraft
Annex 8—Airworthiness of Aircraft
Annex 17—Security
The relevant sections of Annexes 6, 8, and 17 are attached to this statement for further reference.
Annex 1 – Personnel Licensing requires that all airline pilots undergo a periodic medical examination
(by a doctor who is trained in aviation medicine) that includes both a physical and a mental assessment. If there is any concern from this medical screening then a further, more specialized, assessment can be undertaken that may include neuropsychological testing. Pilots also undergo periodic simulator checks as well as checks of performance during routine operations.
