The FAA has restored public access to its registry of Part 135 certificate holders and their associated aircraft, ending a period during which that information was unavailable to operators, brokers, consumers, and industry researchers. The Part 135 list historically allowed anyone to look up which companies hold on-demand charter certificates, what aircraft are listed on those certificates, and other operational details tied to specific certificate numbers. Its removal — even temporarily — created a gap in publicly accessible safety and verification infrastructure that the broader charter ecosystem relies upon to function with baseline transparency.
For charter brokers, fractional program managers, and corporate flight departments that routinely outsource lift, the availability of this list carries direct operational consequence. Verifying that a proposed vendor actually holds an active Part 135 certificate — and that specific tail numbers are listed on that certificate — is a foundational due-diligence step before placing passengers on a charter flight. During the hiatus, that verification had to occur through more indirect channels, including direct requests to operators or consultations with third-party vetting services. The restoration reduces friction in a process that, when shortcuts are taken, has historically preceded accidents involving illegal charter operations and unlicensed carriers.
The temporary disappearance of the list also reflects a broader tension the FAA has navigated in recent years between data transparency and security or privacy concerns. Several government aviation databases have been subject to intermittent access restrictions, delayed updates, or outright removal following policy reviews — the aircraft registration database and pilot certificate lookup tools have both experienced periods of reduced public accessibility. In each case, the downstream effect on industry stakeholders has been significant, as those tools are deeply embedded in compliance workflows, insurance underwriting, and operator vetting processes used across Part 91, 91K, and 135 operations.
For working pilots, the restoration is a reminder of how much professional aviation infrastructure depends on publicly maintained government datasets. Pilots operating under Part 135 certificates are directly affected when certificate status information is inaccurate or inaccessible, particularly during ramp checks or when operating into foreign jurisdictions that may cross-reference U.S. FAA records. Crews flying for certificate holders also benefit from the transparency this list provides, as it supports accountability in a segment of the industry where certificate fraud and unapproved operations have posed recurring safety challenges. The FAA's decision to restore access — rather than leave the gap unaddressed — signals a recognition that public-facing data tools serve regulatory and safety functions beyond mere administrative convenience.
