A pilot should proceed as follows regarding an incident in which he is or has been involved:
(a) during flight, use the appropriate air/ground frequency for reporting an incident of major
significance, particularly if it involves other aircraft, so as to permit the facts to be ascertained
immediately; and
(b) as promptly as possible after landing, submit a completed "Air Traffic Incident Report Form":
(i) to confirm a report of an incident made initially as in (a) above, or for making the initial
report on such an incident if it had not been possible to report it by radio; and
(ii) to report an incident which did not require immediate notification at the time of
occurrence.
