CAWIS Web Notice
Transport Canada is now distributing Airworthiness Directives (ADs) and Civil Aviation Safety Alerts (CASAs) to aircraft owners, aircraft maintenance engineers (AMEs) and foreign civil aviation authorities primarily through e-mail. Transport Canada is moving in this direction to reduce its environmental footprint and better manage public funds. In addition, electronic distribution is much quicker than standard mail.
If you are an aircraft owner, AME or foreign civil aviation authority, Transport Canada recommends that you join the AD / CASA electronic mailing list by sending an email to email@example.com. If you do not belong to one of these groups and would like to receive notification of new ADs and/or CASAs, you may sign up via e-news.
If you have any questions or require further information, feel free to contact us by e-mail at firstname.lastname@example.org or by phone at 1-888-663-3639.
Continuing Airworthiness Web Information System (CAWIS)
Requests from both registered aircraft owners and Transport Canada (TC)
personnel for an Internet/Intranet based computerized airworthiness system have resulted
in the development of this site.
This site is mainly for the use by registered owners, operators, maintainers
and manufacturers of Canadian registered aeronautical products or products
for which Canada is the Country of Type Design responsibility, as well as Transport
External clients can utilize this site to
- Submit their Annual Airworthiness Information Report (AAIR)
- Query the Airworthiness Directive (AD) (foreign & domestic) database
- Review the data pertaining to their own aircraft
Internal clients (TC personnel)
- CAWIS has replaced the Computerized Airworthiness
Information System (CAIS). CAWIS offers several convenient enhancements.
Fast, Convenient, Confidential
Visitors to this site can search the AD database using the "Quick Query" or
"Advanced Search" Functions available by selecting the "Airworthiness Directives"
link located directly on this specific page.
AAIR submission requires the registered aircraft owner to logon to CAWIS using the
AAIR Access Code that is indicated directly on the top right corner of the AAIR form that
is mailed to you by TC.
This system has been designed to ensure that information pertaining to the registered
owner's identity, along with personal information, remains confidential.
