2.7 MMEL Format

a Each MMEL should contain a coverapproval page, a Log of Revisions, a Reason for Changes page, a List of Effective Pages, a Table of Contents, an explanation of the symbols used in the MMEL and a definition of any terms having special meaning in the context of the MMEL. Each item of equipment listed in the MMEL shall be described and identified in accordance with the Air Transport Association ATA specification 100 code system See Appendix M. The number of each item of equipment installed and the number required to be operative for dispatch shall be stated in the appropriate columns. b Any conditions associated with inoperative equipment, required to maintain a level of safety, shall be included in the “Remarks or Exceptions” column. c When practicable, the switch, lever, gauge or indicator of a particular item of equipment, should be identified. Source MMELs may indicate a requirement to placard inoperative equipment by use of an asterisk in column 4 to inform crew members of its condition. d For operator MELs, a definition shall be added which shall state that each inoperative item must be placarded to inform and remind the crewmembers and maintenance personnel of the equipment condition.

2.8 MMEL Page Format

a MMELs 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 C. Other formats may be accepted for MMELs provided they are clear and unambiguous. Each MMELMEL will be preceded by an acceptable preamble. An example is given in Appendix D. 2.9 Operating and Maintenance Procedures Any inoperative item of equipment in the MMEL which would require an operational or maintenance procedure to ensure the required level of safety, shall be so identified by an appropriate symbol in the Remarks or Exceptions column of the MMEL. This will normally be O for an operational procedure and M for a maintenance procedure. O M means both operational and maintenance procedures are required. Details of such procedures must be made available for review during the MMEL acceptance process as they form part of the justification supporting inclusion of an item in the MMEL. Where applicable, the limitations, procedures and remarks for individual MMEL items should cover at least day, night, VMC, IMC, ETOPS, icing, rain, and Category IIIII.
