Distribution rules
A TC published AD involving Canadian TCH products should be distributed to

all other special interest groups requesting updates on that product (SIGS module)
all TC regional office reference centers
A TC published AD involving Non-Canadian TCH products should be distributed to

only the Civil Aviation Authority that is the TCH holding country of that product (SIGS module)
if possibly, the manufacturer contact for that product (SIGS module)

A Foreign published AD involving Canadian TCH products, should be distributed to

Notes:
Type certificate Holders (TCH)
Not ALL Canadian ADs pertain to Canadian TCH products, only
Canadian products are occasionally found on Foreign issued ADs and are sometimes adopted by TC (though, normal practice is that TC reviews the AD, and then issues a Canadian AD afterward)
Emergency AD’s
Distributed immediately upon publication or receipt by TC. An AD of this nature usually requires immediate corrective action by the owners of this product
MDM outages
Record lock can occur. (up to 2 hours before reset)
Exchange server password changes ? (controlled by shared services)
possibly an export script outage ? The MDM looks for the document on the Internal web server ( https://tcapps.tc.gc.ca/Saf-Sec-Sur/2/AwD-CN/documents/ )
The publications group has the option to gather and BCC a full distribution in event of an emergency, if/when the MDM is offline.
Document formats
Beginning in 1996, all Canadian ADs and applicable foreign ADs were scanned to HTM format. HTM publication continued until 2015.
PDF publication began in 2005 in conjunction with HTM, and is not the only format exported to AD web, except in cases where the inspectors are posting old ADs on newly acquired products, and HTM is the only format available. PDF’s were produced
Sale Reported / Invalid Address operators
Identified on the Y93 table by Sale_reported = “Y” - or - Active_flag = “I” . Either of these conditions render the operator uncontactable by CAWIS and these operators are exempted from both AD and AAIR distribution until such time as legitimate contact data is re-established in CCARCS.
