This advisory circular (AC) provides information for operator development and use of a
minimum equipment list (MEL), MEL management program, nonessential equipment and
furnishings (NEF) program, and Configuration Deviation List (CDL). This AC applies to all
operators subject to Title 14 of the Code of Federal Regulations (14 CFR) parts 91 subpart K
(part 91K), 121, 125, and 135. The use of an MEL should only be authorized through the
issuance of Operations Specification (OpSpec) or Management Specification (MSpec) D095,
Minimum Equipment List (MEL) Authorization, as appropriate. This AC does not address
operations conducted under part 91, § 91.213 with inoperative instruments or equipment without
an MEL.
This AC describes an acceptable means, but not the only means, for an operator to develop and
use their MEL, NEF, and CDL in accordance with regulatory requirements and Federal Aviation
Administration (FAA) policy. The contents of this document do not have the force and effect of
law and are not meant to bind the public in any way, and the document is intended only to
provide information to the public regarding existing requirements under the law or agency
policies.
