What can be done to force or encourage the replacement of noisy jets?
Aircraft that currently opperate at any MAC-owned airport must meet Stage 3, Stage 4 or Stage 5 noise standards.
While older model aircraft and hush-kitted aircraft (e.g., DC-9, Boeing 727, etc.) produce a greater noise impact on the airport's neighbors than quieter and newly-manufactured aircraft, the MAC does not have the authority to restrict the types of aircraft that are used at any of its seven airports. However, the Federal Aviation Administration (FAA) does have the authority to establish and regulate aircraft noise standards.
The FAA was directed by Congress to enforce the Airport Noise and Capacity Act of 1990, which mandated that all commercial service aircraft over 75,000 pounds comply with Stage 3 noise level criteria by January 1, 2000. This means that as of thsi date commercial service hush-kitted aircraft must meet at least Stage 3 standards in order to operate at MSP. Furthermore, the FAA mandated that all aircraft under 75,000 pounds must meet Stage 3 standards by January 1, 2016.
