Nonessential Equipment and Furnishings Program (NEF): Allows operators to use the deferral authority granted in the MMEL to provide relief for inoperative, damaged, or missing nonessential items.
Operators who hold an LOA authorizing the use of an MMEL as an MEL or a customized MEL can only defer items listed in their MELs or via their NEF Program. Therefore, if an operator does not have an NEF Program, any inoperative nonessential items must be operative for flight.
