FAA's Enforcement of Noise Rules at National Airport Gao ID: RCED-88-117 April 15, 1988

In response to a congressional request, GAO reviewed the Federal Aviation Administration's (FAA) monitoring and enforcement of aircraft noise rules at Washington National Airport.

GAO found that: (1) between January 1982 and June 1987, FAA monitored all flights between 10 P.M. and 7 A.M. for compliance with the nighttime rule and imposed penalties for violations; (2) FAA exempted noncompliant operations which it determined were beyond operator control; (3) during the past 6 years, flights during peak traffic hours have exceeded high-density rule limits by up to 13 percent; (4) since its monitoring equipment broke down in 1985, FAA has relied on voluntary operator compliance with the airport's noise abatement procedures; and (5) it was unable to determine the number of violations or the rate at which FAA imposed penalties, since FAA did not maintain adequate records. GAO noted that the Metropolitan Washington Airports Authority budgeted funds to purchase monitoring equipment as part of its responsibility for noise abatement.
