The Nantucket Memorial Airport Commission voted unanimously Jan. 14 to adopt revised rates and charges that raise many aeronautical fees by 3.5% and change how hangar rents are calculated.

Airport manager Billy Coburg told the commission the package applies a consistent percentage increase to landing, ramp and overnight fees and adjusts hangar rents using a square‑foot methodology rather than engine count. Coburg said the changes are intended to help the airport recover operating and maintenance costs as federal grant purchasing power declines and inflation increases.

The revisions include a change to the landed‑weight multiplier used for terminal users, from $3.61 to $3.74 per $1,000 of maximum gross takeoff weight, and a reduction in the signatory carrier waiver from 62% to 60% for signatory carriers. Coburg said ramp fees and overnight fees were raised by the same 3.5% percentage and that the airport LEO assessment will increase to $0.41 per enplaned passenger. Tie‑down and T‑hangar rents were adjusted; Coburg said the T‑hangar rate will be $435 per month.

On hangar rent methodology, staff proposed setting a base rate equal to a 1,000‑square‑foot baseline (based on the Cessna 172) and charging an additional $0.75 per square foot. Coburg walked commissioners through example impacts under the new methodology: a Cessna 172 would increase from $315 to $327 monthly; a Cessna 402 would move from $630 to $765; a Piper Malibu (Piper PA‑46) example rose from $315 to $512; a Pilatus PC‑12 example rose from $945 to $1,445; a Beechcraft King Air would decrease from $1,575 to $1,319; and the Cirrus Vision Jet example would decrease from $1,575 to $461 under the new approach. Coburg said the total hangar revenue is not a major revenue center for general aviation operations but that the method better allocates cost by space as aircraft types and technology evolve.

Coburg said the rate changes would take effect April 1. The commission closed the public hearing on the proposal and then moved to adopt the rates as published; the motion carried on a roll‑call vote with Commissioners Planzer, Buscaren, Marks, Ms. Flancher and Chair Arthur Gasparo all voting aye.

Commissioners and staff said the changes aim to preserve economic sustainability by having direct users bear more of the operating costs rather than taxpayers, and staff will provide the redline and final packet materials for reference.

The commission did not identify further public comments on the rates during the hearing.
