Introduction This Transport Canada MMEL Supplement constitutes a mandatory change to the FAA Approved MMEL for the Learjet 24, 25, 28, 29, 35, 36, 55 aircraft. This MMEL Supplement must be used in conjunction with the FAA Approved MMEL (Revision No. 6a or later applicable revision). The information contained herein supersedes the existing FAA Approved MMEL only for those items listed herein. For items not contained in this Supplement, consult the FAA Approved MMEL. Operating and/or maintenance procedures referred to in this Supplement are the same as those supporting the FAA Approved MMEL unless otherwise indicated. Procedures required by the Transport Canada MMEL Supplement and not indicated in the FAA Approved MMEL must be provided by the operator. The FAA Approved MMEL has entries where the “Remarks or Exceptions” column makes reference to applicable FARs. Unless such an entry is superseded by an item in this Supplement, all references should be made to the applicable Canadian regulations. This MMEL Supplement uses the standard four column format as referenced in the Transport Canada MMEL/MEL Policy and Procedures Manual (TP 9155E). The same definitions and symbols as the FAA Approved MMEL are also used. Items which have no MMEL relief (i.e. relief withdrawn) are not categorized. Comments and inquiries should be directed to: Transport Canada Chief, Flight Test – AARDC Aircraft Certification 330 Sparks Street Tower C, 3rd Floor Ottawa, Ontario K1A 0N8
