Airworthiness Notice - C004, Edition 7 - 31 March 2005
Maintenance Release Privileges;
Older Aircraft and SFAR 41C Aircraft
(This Airworthiness Notice supersedes AN C004 Edition 6, dated 12 July 2001.)
Purpose
The purpose of this notice is to provide guidance when
assessing the scope of maintenance release privileges for the current
aircraft maintenance engineer (AME) licensing model, introduced by the
issuance of Canadian Aviation Regulations Standard 566. This notice also
includes information relating to issuance of the Transport Canada (TC)
Global Exemption from subsection 571.11(1) of the Canadian Aviation
Regulations (CARs) dated 09 July 2001.
Background
Upon implementation of the current licensing model
(August 1999) all holders of a valid AME license were assessed by TC and
reissued with an appropriately rated AME licence. The TC assessment was
based on the scope of the maintenance release privileges of the current
licensing model and the certification basis of the aircraft type designators
previously held.
On 9 July 2001, TC issued a Global Exemption from
subsection 571.11(1) of the CARs, which revised the maintenance release
privileges for holders of both M1 and M2 rated AME licences. This exemption
detailed the new AME licence privileges pertaining to turbine-powered
helicopters and SFAR 41C aeroplanes, including their associated variants and
derivative Airworthiness Manual (AWM) 523 Commuter Category models. The
information provided by the exemption has now been incorporated into STD
566.03(8)(b) as of September 2003.
Assessment
In order to exercise the privileges of an AME licence,
and sign a maintenance release in accordance with Chapter 571.11 of the
CARs, an individual must hold a valid AME licence with a rating appropriate
to the aeronautical product being certified. This means that the AME licence
holder must ensure that their licence rating includes the aircraft type for
which the maintenance release is being signed, based on the design standards
in place at the time the aircraft was type certified.
Aircraft type certificates issued prior to the 1965
recodification of the United States design standards will not have a direct
reference to Canadian AWM design standards such as AWM 522, 523, 527, 525,
etc. In such cases, it may be difficult for AME’s with a single M-Aircraft
rating to determine whether a particular aircraft falls within their scope
of maintenance release privileges.
Appendix A of this notice gives an explanation, and
some examples, of how to assess an aircraft type to determine the applicable
AME licence rating. This appendix focuses on aircraft that were type
certified prior to the United States recodification or where an aircraft
certification basis may not be readily known.
Appendix B of this notice gives an explanation of the
requirements stated in STD 566.03(8)(b) and the maintenance release
privileges for holders of both M1 and M2 rated AME licenses.This
appendix also includes a list of applicable aircraft affected by the
exemption.
Appendix C of this notice gives an explanation of the
privileges associated with the E, S, and Balloon ratings, including an
example of their associated maintenance tasks.
Signing of a Maintenance Release - Training Requirements
In addition to having the appropriate ratings, AME’s are
required to have completed training appropriate to the type of aircraft,
engine or system on which the work was performed on, (ref: CAR 571.11), for
example:
Transport Category aircraft:
AME’s are required to have successfully completed an
aircraft type or engine (as applicable) course that has been approved by, or
recognized (validated) by, Transport Canada.
SFAR 41C Aircraft:
AME’s are required to have obtained a sufficient level of
training on the aircraft type for which privileges are granted and/or
exercised.
Turbine powered rotorcraft:
AME’s are required to have successfully completed an
aircraft type course that has been approved by, or recognized (validated)
by, Transport Canada. The requirement for appropriate training applies to
both an M1 and M2 licence holder when exercising the privileges associated
with the provision of STD 566.03(8)(b).
Aircraft Electronic Systems // Aircraft Structures:
AME’s are required to have obtained appropriate training
on the system/component for which privileges are granted and/or exercised.
