15 states sue the FAA to void its nationwide drone delivery clearance

Fifteen US states and Harris County, Texas have asked a federal appeals court to throw out the Federal Aviation Administration's nationwide environmental clearance for drone package delivery. The petition was filed in the US Court of Appeals for the Second Circuit on Monday 28 September 2026, led by New York Attorney General Letitia James. It targets the finding of no significant impact the FAA signed on 28 July 2026, which lets the agency approve new Part 135 delivery markets against a single national study instead of a fresh environmental assessment for each one.

What the petition challenges

The document under challenge is the FAA's Final Programmatic Environmental Assessment for drone package delivery, with its finding of no significant impact and record of decision. A programmatic assessment is a National Environmental Policy Act review written once at national scale, so later project-specific decisions can tier off it. The FAA concluded that, with the mitigation measures set out in the assessment, the proposed action "would not significantly affect the quality of the human environment" — in every US state, Alaska and Hawaii included.

The finding is not open-ended. It applies to Part 135 delivery flights kept inside a defined noise and siting envelope: no more than 1,150 average daily deliveries from a single hub, a minimum setback of 183 m (600 ft) from homes and other noise-sensitive sites, en-route altitudes of roughly 46–114 m (150–375 ft) under a 122 m ceiling, and aircraft of no more than 50 kg (110 lb).

The coalition says that conclusion rests on analysis too thin to support it: the FAA, it argues, failed to adequately evaluate the noise, safety and privacy effects of routine drone traffic over populated areas. California Attorney General Rob Bonta said the assessment "falls far short of properly analyzing environmental impacts". DroneXL points to two specific gaps: the noise baseline the FAA worked from counts only aviation noise, and hazardous materials were dismissed from detailed review on the expectation that operators follow transport and disposal rules — a decision taken roughly ten months after an Amazon MK30 battery fire near Tolleson, Arizona.

The objection is not new. Seventeen state attorneys general and Harris County opposed the draft in a comment letter on 23 January 2026, calling it "a paper exercise, largely devoid of reliable qualitative or quantitative analyses" and asking for a full environmental impact statement. The FAA published the final assessment six months later.

The decision opened a 60-day window for legal challenge; it ran out on Saturday 26 September, and the petition arrived on the Monday. The FAA had not publicly responded as of 29 September, AVweb reported.

Why it matters for operators and residents

The assessment is the administrative spine of the expansion now under way. Amazon's Prime Air said in August 2026 that it plans to reach customers in nearly 500 US cities and towns by the end of the year, a roughly sixfold increase from 11 sites across 10 metropolitan areas. Its current aircraft, the MK30, has a maximum take-off weight of 37.7 kg (83.2 lb) — inside the envelope's 50 kg limit — and an operating range of about 12 km (7.5 mi). Wing is separately seeking approval for a Houston-area expansion covering up to 75 sites. DroneXL lists Amazon Prime Air, Wing, Zipline, DoorDash Air, Matternet and Flytrex among the Part 135 operators whose approvals since 28 July rest on the challenged finding.

If the Second Circuit sets the finding aside, the FAA would have to supplement or redo the national review, and new approvals would fall back to the slower case-by-case route — the route used for Zipline's Dallas–Fort Worth service, whose final assessment was signed in December 2025, and still used for the five-metro Texas draft published in September 2026. For residents, it is the first broad legal test of whether one national study can substitute for local review of flights over individual streets.

How the framework changed in July

Before July 2026, each delivery market was effectively its own NEPA file: DroneXL counts more than 20 one-off market reviews completed between November 2021 and July 2025, each typically taking six to eight months. Commercial UAV News describes the July decision as a shift to a national framework in which operators plan networks against standardised assumptions rather than negotiating market by market. The trade is that those assumptions are generic: the assessment covers locations not yet named, which is what the states object to most directly.

The litigation does not touch the aircraft or their certification. Zipline's Platform 2, which hovers and lowers packages on a tether, and the tilt-rotor designs of Wingcopter keep flying their routes; heavier uncrewed freighters such as the Elroy Air Chaparral sit outside the Part 135 package-delivery category entirely. What the petition disputes is the paperwork that decides where small delivery aircraft may fly.

What happens next

A petition for review does not by itself suspend the decision it challenges, so the finding stays in force and the FAA can keep approving markets while the case proceeds. The court can uphold it, leaving the national framework intact, or set it aside and send it back to the FAA to expand its analysis of noise, safety, privacy or battery hazards.

Frequently asked questions

Does the lawsuit stop drone deliveries?

No. Approvals issued under the July finding remain valid unless the Second Circuit grants a stay or vacates the finding.

What is a programmatic environmental assessment?

It is a single National Environmental Policy Act review written at programme scale — here, drone package delivery nationwide. Later site-specific decisions tier off it instead of repeating the analysis; operations beyond its analysed scope need separate review.

Which states filed the petition?

New York, Arizona, California, Colorado, Delaware, Illinois, Maine, Maryland, Massachusetts, Michigan, New Mexico, Oregon, Rhode Island, Washington and Wisconsin, plus Harris County, Texas.

Does this affect recreational or Part 107 pilots?

No. The clearance covers commercial package delivery flown by Part 135 air carriers. Recreational flying and Part 107 operations run under separate rules and are not part of this case.
