The FAA has once again delayed the new Grand Canyon Special Flight Rules Area (SFRA) final rule and commercial air tour routes that were scheduled to go into effect April 1. The agency is reexamining "safety of flight" issues. The new rules would primarily affect commercial air tour operators but also include two flight-free zones over the east end of the national park.
AOPA had successfully objected to parts of the rule that would have imposed greater restrictions on transient GA aircraft crossing the canyon. (See " Grand Canyon overflight rules will have little impact on general aviation, thanks to AOPA.")
