    Inoperative Instruments & Equipment

    Federal Aviation Regulations generally require that all equipment installed on the aircraft be operative at the time of flight. However, depending on the kind of operation and size and type of aircraft, the aircraft may still be airworthy with some specific kinds of equipment inoperative.

FAA Extends Compliance Date for Expired Navigation Databases in Minimum Equipment Lists
Nov. 1, 2017
The FAA has published revised guidance concerning expired databases and minimum equipment lists (MELs). Notice N 8900.440, "Master Minimum Equipment List (MMEL) Policy Letter 98, Revision 1, Navigation Databases and Associated Aviation Safety Inspector Requirements" provides guidance to the FAA's Aircraft Evaluation Division and aviation safety inspectors with MEL oversight responsibility, as well as to aircraft operators authorized to use MELs. The new guidance disallows MEL relief for expired navigation databases, but permits operators to implement procedures for using expired navigation databases in another manual. Learn more about the FAA's revised guidance.
FAA Realigns Flight Standards for Consistency, Agility
Sept. 13, 2017
The FAA recently began a service-oriented effort to change the culture of its Flight Standards organization. The initiative, named the Future of Flight Standards, aims to facilitate critical thinking, interdependence and consistency to better serve aviation safety. "Part 91 operators have increasingly more contact with local inspectors for a number of reasons, including requesting letters of authorization and other operational requests," said Doug Carr, NBAA's vice president of regulatory and international affairs. “We hope the FAA's reorganization of the Flight Standards organization will address industry challenges, such as siloed and inconsistent interpretations of regulations and policies, and result in more consistent outcomes for operators across the country." Learn more about the realignment.
MEL Changes Required for Flying With an Expired Navigation Database
Sept. 6, 2017
In a recent revision to FAA Policy Letter 98 (PL-98) – which provides standardized MMEL relief to operators with out-of-currency navigation databases (NDBs) – the agency determined that expired databases do not meet the definition of "inoperative" equipment, and are not authorized for MMEL relief per 14 CFR. "PL-98 Rev 0 provided standardized MMEL relief for out-of-currency navigation databases, but PL-98 Rev 1 prohibits MMEL relief for expired NDBs and instead provides relief only for inoperative NDBs," said Tom Atzert, president of Leading Edge ATS and co-chair of the MMEL Industry Group.

NBAA Opposes FAA Proposal Regarding Expired Navigation Databases
July 7, 2016
NBAA recently submitted comments to the FAA opposing the agency’s proposed revision to Master Minimum Equipment List Policy Letter-98, Navigation Databases (MMEL PL-98). The proposed revisions would rescind operators’ ability to defer an expired navigation database in accordance with a minimum equipment list, as is currently permitted. NBAA’s comments highlight how the proposed revision to MMEL PL-98 is not in agreement with the FAA chief legal counsel’s interpretation addressed to Thomas Letts in November 2012 (known as the Letts interpretation). Letts asked the FAA if he might supplement his expired navigation database with an iPad, and the agency said that to fly with an expired navigation database, an operator must utilize an approved MEL that allows for dispatch of an aircraft with inoperative equipment.

Proposed FAA Policy Change Would Affect Mechanics with Inspection Authorization
November 29, 2010
The FAA has issued a Notice of Proposed Policy which is intended to clarify the definition of "actively engaged" for purposes of issuing and renewing the Airframe and Powerplant (A&P) Mechanic Inspection Authorization (IA). This proposed policy is a significant change to the long-established practices for IA qualifications. FAA regulations require that an individual A&P seeking inspection authorization "be actively engaged, for at least the prior two-year period, in maintaining aircraft to be eligible to obtain or renew an IA." In the past, FAA ASIs have allowed IAs who do not work on the shop floor or who clearly do not work full time with aircraft to renew their IA after complying with the minimum annual eight-hour training requirement. NBAA encourages its Member companies to submit comments to FAA on this policy proposal, which are due by December 6, 2010. Learn more.
NBAA Releases Guidance on Proposed Security Rule for Aircraft Repair Stations
November 20, 2009
Earlier this week, the Transportation Security Administration (TSA) published a notice of proposed rulemaking (NPRM) which would affect aircraft repair stations certificated under FAR Part 145. The proposed regulations would establish requirements for repair stations to adopt and implement a standard security program and to comply with security directives issued by the TSA. The proposed regulations would also provide procedures for the TSA to notify repair stations of any deficiencies in their security programs, and to determine whether a particular repair station presents an immediate risk to security. The TSA has provided 60 days for public comments on the proposal, which are due by January 19, 2010. View NBAA’s analysis of the proposed rule.
