The undersigned business and trade associations write regarding the delayed development of the Federal Aviation Administration’s (FAA) Notice of Proposed Rulemaking (NPRM) to Prohibit or Restrict the Operation of an Unmanned Aircraft in Close Proximity to a Fixed Site Facility. We have significant concerns that continued delays in promulgating this NPRM will adversely impact the safety and security of the national airspace, while this inaction effectively has invited states to enact varying restrictions on UAS operations.
