Full Breakdown

Federal law occupies the field of aircraft noise regulation through the Federal Aviation Act of 1958 and the Noise Control Act of 1972. Maryland's COMAR 26.02.03.06 expressly exempts aircraft in flight from state noise limits, recognizing federal preemption. The Maryland Aviation Administration coordinates noise abatement programs at BWI Marshall and Martin State airports under federal Part 150 noise compatibility studies. Airport proprietors may impose limited curfews and operational restrictions if FAA-approved, but local governments cannot directly regulate aircraft. Ground-based airport operations and run-up testing remain subject to state and local noise rules.
