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.

This AC provides one means,
but not the only means, of ensuring that the contemplated maintenance, alteration, or
continue-in-service condition is in compliance with applicable regulations and existing
policy. This AC is not mandatory and is not a regulation. 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. The AC recommends acceptable methods
by which:
1. Title 14 of the Code of Federal Regulations (14 CFR) part 43, § 43.13(c) allows
commercial operators, operating under 14 CFR part 121; part 129, § 129.14(b)(3);
and part 135, § 135.411(a)(2),1 to meet the requirements of § 43.13(a) and (b) by
applying the maintenance methods, techniques, and practices of their maintenance
manual or the maintenance portions of the manual. This AC describes that means of
compliance.
1 For the purposes of this AC, part 121 operators, part 135 operators operating under § 135.411(a)(2), and § 129.14
operators holding operations specifications (OpSpecs) which require a continuing airworthiness maintenance and
inspection program are referred to collectively as “operators.”
2. These operators may continue to use articles in-service or perform maintenance and
alterations in a different manner than incorporating the manufacturer’s maintenance
information. Other methods, techniques, and practices may be incorporated into the
operator’s manual so long as the methods, techniques, and practices are an acceptable
standard to the Administrator, as required by § 43.13(c). An operator may not
produce or incorporate in their manual a method, technique, or practice that is not
based on accepted standards (refer to § 43.13).
