This Transport Canada Master Minimum Equipment List (MMEL) Global Change (GC) revises MMEL relief for Crew Member Interphone System found in item 23-40-1 of the TC MMEL Guidance Book, Revision 07, dated 27 April 2009.
This GC is an approved addendum to all affected existing MMELs and in accordance with TP 9155 (Second Edition, January 2006) paragraph 2.6.5, affected MELs should be amended accordingly. Approval of the revised MEL shall be gained using normal procedures.
TC MMEL Guidance Book item 23-40-1, domestic MMELs, and TC Supplements will be amended in the future to reflect the revised relief for a Crew Member Interphone System in accordance with this GC.
SUBJECT: CREW MEMBER INTERPHONE SYSTEM
Discussion:
MMEL relief for a Crew Member Interphone System found in item 23-40-1 of the TC MMEL Guidance Book Revision 07 permits the system to be inoperative.
CASS 725.104 permitted operations with a Crew Member Interphone System inoperative when operating in a ratio of one flight attendant for each 50 passenger seats on an aeroplane configured for 50 or less passenger seats. CASS 725.104 was revoked, and therefore, the MMEL relief is also revoked.
This GC 10 revises item 23-40-1 of the Guidance Book to reflect the changes to the Canadian Aviation Regulations.
