Revise laws related to airports and light aircraft

This bill requires Montana airports that receive any public funding to provide free services to light aircraft, including landing, taxiing, and parking with tie downs for up to three days. It also mandates that these airports allow light aircraft access to secure areas for passengers and crew when applicable, without charging fees for these services. The law defines a light aircraft as one weighing less than 9,000 pounds that operates under specific federal regulations. Additionally, the bill prohibits charging additional fees for landing, taxiing, parking, or security unless those fees are clearly disclosed and agreed upon before each flight.
