Master Minimum Equipment List
Items that qualify as a GC are generally those items that are required to be
installed by a new regulatory requirement, or are MMEL items that are affected
by TC policy decisions. Examples are GPWS and CVR which result from
regulatory requirements; and Transport Canada MMEL Guidance Book
(TCGB) items such as Flap Position Indicator, which reflects a policy decision.
c) Purpose
The purpose of GCs is to recind, modify or offer additional MEL relief for items
prior to release of the revised MMEL or TC Supplement. The GC system is not
intended to replace the normal MMEL revision process and affected MMELs or
TC Supplements will incorporate all GCs issued up to the date of each revision.
d) Procedure
The allowable relief stated in the associated TCGB item will be in the form
of a proviso (Column 4 of the MMEL format), and where applicable, should
be copied verbatim into the MEL.
Some wording changes may be required to cater to a particular aircraft
configuration. The air operator's MEL revision can be approved in the
normal manner on the basis that the GC is an approved addendum to the
existing MMEL.
GCs will be released with consecutively assigned control numbers (TCGC-
1, TCGC-2, etc.) and will reference the appropriate item in the Guidance
Book. Both the GCs and the TCGB are available on the MMEL/MEL web
page. When a MMEL is revised, the Reasons for Changes List will state
which numbered GCs have been incorporated in that revision.
