On February 15, 2015, the Federal Aviation Administration published its highly anticipated Notice of Proposed Rulemaking (NPRM) on the Operation and Certification of Small Unmanned Aircraft Systems (applicable to UAS weighing 55 lbs. and less). The proposed rules would add a new Part 107 to Title 14 Code of Federal Regulations to allow for routine civil operation of small UAS in the National Airspace System (NAS). Although a lengthy comment and revision period is expected to delay finalization of the regulations for another 18-24 months, Section 333 of the FAA Modernization and Reform Act of 2012 will continue to provide a procedure for expedited authorization of commercial small UAS operations in the interim. The final Part 107 will serve as the foundation for a multi-billion dollar UAS industry in the United States.
