Civil Aviation Safety Alerts

(formerly Service Difficulty Advisories and Service Difficulty Alerts published prior to October 1, 2010.)

The Transport Canada Civil Aviation Safety Alert (CASA) is used to convey important safety information and contains recommended action items.

The CASA strives to assist the aviation industry's efforts to provide a service with the highest possible degree of safety.

The CASA may be changed or amended should new information become available.

IMPORTANT:

Transport Canada is now distributing 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 CASA electronic mailing list by sending an email to cawwebfeedback@tc.gc.ca. If you do not belong to one of these groups and would like to receive notification of new CASAs, you may sign up via e-news.

Questions

If you have any questions or require further information, feel free to contact us by e-mail at Services@tc.gc.ca or by phone at 1-800-305-2059.
