Airworthiness Notices - A001, Edition 4 - 27 August 1997

Introduction of Airworthiness Notices

(This Airworthiness Notice supersedes AN No. A001 Edition 3 )
(dated 28 June 1996.)


This notice provides information about the Airworthiness Notice (AN) publication.

The Airworthiness Notice was first introduced in 1993 as a replacement for the former Notice to Aircraft Maintenance Engineers and Aircraft Owners (N-AME-AO), which is now completely phased out.

Depending on the subject matter,  Ans are issued either individually or jointly by the Aircraft Certification Branch or the Maintenance and Manufacturing Branch of Transport Canada's Safety and Security Group, Civil Aviation Directorate.  They are published by the Continuing Airworthiness Division at Transport Canada Headquarters in Ottawa.


Airworthiness Notices are published in four series, depending on the type of information presented or the distribution required:

Series A Administrative matters White paper
Series B Matters directly affecting airworthiness Pink paper
Series C Matters concerning only aircraft maintenance engineers (AMEs) Yellow paper
Series D Similar to Series B, but generally concerning only a limited number of aircraft owners Blue paper

Ans are identified by a series letter, a sequence number (within the series), an edition number (to indicate the first or subsequent releases on the same subject), a date of issue and a title (subject).  For example, AN A001 Edition 3, 28 June 1996, Introduction of Airworthiness Notices, was the third release of the first AN in Series A (administrative matters) and was issued on 28 June 1996.

Individual Ans may be cancelled or revised from time to time.  Revisions of existing  Ans normally bear the same number with a revised edition number and date.  Whenever practical, changes are highlighted by vertical bars in the right margin.

The D series of AN disseminates information similar to that found in Series B, but which concerns only a limited number of the normal AN recipients.  Distribution of Series D notices is normally very minimal.  For example, the former AN B024, Single-Pilot Operation of the Cessna Models 500, 550, S550, 552 and 560 Aircraft, was re-issued in the D series as AN D002, for distribution only to owners/operators of those specific aircraft models, approved organizations, libraries, etc.

An index is published periodically to record the revision status of all current Ans.


Airworthiness Notices are distributed to owners of aircraft listed on the Canadian civil aircraft register, to licensed AMEs, to Transport Canada approved organizations, and to others as indicated in the accompanying table.  There is no charge for Ans.

Aircraft owners YES YES NO SOME
Approved organizations  e.g. AMOs, AEOs YES YES YES YES
Others, e.g. DARs, schools, libraries YES YES YES YES


  1. Newly licensed AMEs are automatically sent a full set of Ans upon issue of their licence, and all new editions thereafter.
  2. New aircraft owners may request a full set of Ans (see Inquiries, below).
  3. Additional copies of Ans may be authorized in exceptional circumstances (see Inquiries, below).
  4. The only aircraft owners to receive Series D notices will be those whose aircraft are specifically addressed by the particular AN.

Ans are published in separate English and French language versions.  AN recipients may select the language of their choice (see the note at the bottom of page 1).

ANs are also now viewable on the Transport Canada Internet site at (select "Aviation", then "Maintenance and Manufacturing" menu items).

Outdated References

Most other Transport Canada documents which made reference to N-AME-AOs have now been updated to reflect the existence of Airworthiness Notices.  Any remaining references to N-AME-AOs should be translated to refer to Airworthiness Notices.

Further, with the reorganization of Transport Canada Aviation in 1996/97, a number of ANs contain outdated references to the headquarters and regional contact points within the new Civil Aviation structure.  These references will be updated when the respective ANs are revised for their substantive content.
