Master Minimum Equipment List - Transports Canada

2.5.6 Foreign MMELs
Master Minimum Equipment List
a) Transport Canada may accept foreign MMELs approved by the regulatory
authority of the country of manufacture, as published. Transport Canada will
evaluate the foreign MMEL to determine the basis and justification for each
MMEL item.
b) When required, Canadian interpretations, additional airworthiness requirements
and operating rules will be addressed by a TC Supplement, which will be
developed by the MMEL Review Group and produced by Transport Canada.
The TC Supplement will constitute a mandatory change to the foreign MMEL
and will be used in conjunction with it. Where the two documents differ, the TC
Supplement will supersede the accepted MMEL.
2.5.7 Notification of Approval
All MMELs and TC Supplements approved for Canadian air operators are listed on the
MMEL web page and in the Status of Current MMEL List. Most are available in
electronic format and therefore can be viewed or downloaded from the MMEL web page
(See Section 3.8.7).
2.5.8 Third Country MMELs
Transport Canada will not normally accept a MMEL produced by a third country (an
example would be a U.S. MMEL for a European aircraft). However, exceptions may be
made, particularly for older aircraft, if no other source is available or if the use of a third
country's MMEL is more appropriate. Such MMELs should be submitted for acceptance
and be supported by the aircraft manufacturer with appropriate engineering justification.
Only those items which can be adequately substantiated against the levels of safety
discussed in the MMEL Philosophy section of this document will be approved for
Canadian use. Other items will be deleted using the TC Supplement.
Temporary or Interim MMEL Revisions
Manufacturers may issue temporary or interim revisions to their MMELs which may not
be incorporated into the permanent revision for some time.
2.5.9 MMEL Page Format
a) MMELs for domestic aircraft and TC Supplements for MMELs to foreign
aircraft will be published in the “four column format” where columns 1 to 4 will
contain respectively the name of the item and category, number installed,
number required for dispatch and remarks or exceptions.
b) A sample page is provided in Appendix E. Other formats may be accepted for
foreign MMELs provided they are clear and unambiguous. Each MMEL will be
preceded by an acceptable preamble. An example is given in Appendix F.
