4.2.2.7.1 When an arrival report is received by the ATS unit serving the arrival aerodrome, this unit shall transmit an ARR message:
a) for a landing at the destination aerodrome:
1) to the area control centre or flight information centre in whose area the arrival aerodrome is located, if required by that unit; and
2) to the air traffic services unit, at the departure aerodrome, which originated the flight plan message, if that message included a request for an ARR message;
b) for a landing at an alternate or other aerodrome:
1) to the area control centre or flight information centre in whose area the arrival aerodrome is located; and
2) to the aerodrome control tower at the destination aerodrome; and
3) to the air traffic services reporting office at the departure aerodrome; and
4) to the area control centre or flight information centre in charge of each flight information region or upper flight information region through which the aircraft would have passed according to the flight plan, had it not diverted.
4.2.2.7.2 When a controlled flight which has experienced failure of two-way communication has landed, the aerodrome control tower at the arrival aerodrome shall transmit an ARR message:

2) to all other air traffic services units which may have been alerted;

to the ATS unit serving the destination aerodrome; this unit shall then transmit an ARR message to other ATS units concerned or alerted as in a) above.
