A report on whether the Los Angeles Board of Airport Commissioners should move ahead with a ban on certain jet aircraft at Van Nuys Airport is expected to be given when the commissioners meet again on July 17. In April, the board adopted a resolution instructing the Los Angeles World Airports executive director to report back on pursuing the ban of stage 2 aircraft. At the time, the move took business tenants at Van Nuys Airport by surprise because they had not been aware the issue was on the agenda. Robert L. Rodine, a management consultant with clients in the aviation industry, said the commission’s action is counter to a previous decision to include a Stage 2 aircraft ban as part of a larger noise mitigation study, a move that would put it into the realm of objective analysis. “The decision will now be made in the absence of any objective analysis at all,” said Rodine, co-chairman of the Valley Industry and Commerce Association’s aviation committee. The commission’s action reaffirms a position originally taken in 1990 on phasing out the Stage 2 aircraft. In 1999, the commission allowed any of the aircraft that had been tied down or stored at the airport for a 90-day period to remain. Stage 2 is a designation by the Federal Aviation Administration for aircraft with a certain noise level when operating. Stage 1 aircraft are banned in the United States while Stage 3 aircraft are the quietest. Manufacturers stopped making Stage 2 aircraft in 1986. The report from the executive director will focus on four areas a nighttime curfew for planes with takeoff noise levels above 74 decibels; restrictions on repetitive aircraft operations; restrictions on maintenance run-ups; and designating a preferential runway for nighttime hours. The airport currently has a nighttime curfew in place and the shorter of its two runways is not used evenings. During his mayoral campaign, Los Angeles Mayor Antonio Villaraigosa came out in favor of phasing out the Stage 2 aircraft to reduce the noise impacts on adjacent residential neighborhoods.
