The U.S. House of Representatives on Tuesday narrowly defeated an amendment to a transportation appropriations bill that would have allowed Burbank Bob Hope Airport to adopt a mandatory curfew for commercial aircraft operations.

The 208-212 vote against the amendment is the latest setback for the Burbank airfield in its effort to address noise concerns. The amendment was sponsored by Reps. Adam Schiff, D-Burbank, Brad Sherman, D-Sherman Oaks, and Henry Waxman, D-Los Angeles.

The lawmakers expressed disappointment the amendment was defeated as part of the Transportation, Housing, and Urban Development Appropriations Act.

“I will continue fighting on behalf of the thousands of San Fernando Valley residents who have long-sought relief from aviation-related nighttime noise, and look for future opportunities to pass legislative language to make this possible,” Schiff said in a prepared statement.

If approved, the amendment would have exempted Bob Hope from federal regulations so it could establish a mandatory curfew between the hours of 10 p.m. and 7 a.m. instead of a voluntary curfew for those hours.

Getting a mandatory curfew for Bob Hope has been on the agenda of area lawmakers since 2009 when the FAA turned down an application for the proposal. In 2011 and again last year, Schiff and Sherman sponsored the Valley Wide Noise Relief Act but the bill never made it out of committee.
