Highlights of Change

EFFECTIVE ABOVE DATE, the DC-8 Master Minimum Equipment List (MMEL) has been revised. Revision 45 introduces a new format. The changes in this revision were made to align with FAA policy letters, and improve consistency. All changes are reflected in the highlights of change listed below and are indicated by revision bars. Please replace ALL pages for a complete up-to-date MMEL. SEE NOTES BELOW FOR IMPORTANT INFORMATION ABOUT THIS REVISION. Retain this sheet with your MMEL until the next revision is issued.

NOTE 1: Pages WILL NOT be itemized in a CONTROL PAGE for individual revisions. Rather, the ATA section will contain the applicable number of pages and revision number. Any changes to any item within the ATA section will result in the entire section receiving a revision number. To find any revised item within the section see the list below.

NOTE 2: The “Table of Contents” has been replaced with a “Contents” page having System, Pages, and Revision Numbers.

NOTE 3: The “Definitions” pages and “Preamble” pages have been removed. Operators must insert the applicable DEFINITIONS from current Policy Letter 25 and the applicable PREAMBLE from current Policy Letter 34 (Air Carriers) or Policy Letter 36 (Part 91 Operators) into their MEL.

Note: All references to FAR have been replaced with 14 CFR within the ATA Chapters for consistency.
