SUBJECT:

Policy Regarding Cargo Provisions in the MMEL for Cargo Operations

MMEL CODE:

00 (GENERAL)

REFERENCE:

PL-65, Original, dated Apr 2, 1993

Original signed by David S. Potter

PURPOSE:

This policy letter provides the FAA policy regarding the manner in which cargo airplane requirements are to be listed in the Master Minimum Equipment Lists (MMEL).

DISCUSSION:

 

 

Revision 1 reformats policy letter 65 with no change to policy.

 

Different modes of relief between Passenger and Combi operations historically have been shown separately in MMEL's with their respective effectivities reflecting in column one. Cargo operations have typically only been relegated to Notes at the end of the REMARKS column.

 

Today, All-Cargo has become a more predominate configuration for transport aircraft.  The aviation cargo industry position is that the Master Minimum Equipment List (MMEL) should consider the various configurations that aircraft are being operated and provide proper relief based on that configuration.  The cargo industry feels that they are continually required to comply with a higher standard (oriented toward passenger safety) without regard to the cargo configuration and type of operation. The MMEL should be standardized in accordance with the configuration that transport aircraft are being used, either passenger or cargo, whenever a variation in relief is necessary.

 

In some cases identifying that "not required for cargo operations" or "not required for passenger operations" will be the generic and proper proviso (not a note) to literally show the difference.  In other cases, a distinct and separate proviso may be required as in the case of a B-747 that is carrying cargo in its lower deck and passengers in the upper deck.

 

 

POLICY:  

MMEL coverage for cargo configuration airplanes should be clearly identified in the MMEL under column one, with appropriate numbers in column two (number installed) and column three (minimum required for dispatch), and an appropriate proviso in column four.  For B-747 aircraft where passengers are carried on the upper deck and cargo on the lower deck, appropriate relief should be provided for the passenger deck and the cargo deck.

 

The item Public Address System is shown here as an example of how appropriate proviso's for passenger and cargo configurations should be listed in Master Minimum Equipment Lists (MMEL).

Principal Operations Inspectors are to ensure that the appropriate proviso is used for cargo and passenger operations. 

 

Each Flight Operations Evaluation Board (FOEB) Chairman should apply this Policy to affected MMELs through the normal FOEB process.
