At the FAA’s suggestion, and again in-line with our desire to pursue fast-paced innovation in the United States, we also have been exploring another regulatory path to accommodate our research and development needs, an Experimental Certification under 14 C.F.R. § 21.191. However, this alternative entails a lengthy process that was designed for manned aircraft and bears little practical application to small UAS. This process requires certification for each individual vehicle, which is burdensome considering how fast we are designing new Prime Air vehicles. Our first Experimental Certification application has been delayed multiple times as we try to work with the FAA to simplify the process. Disconcertingly, there is no guarantee that this alternative process will provide us the flexibility we need or at the pace we need it. Therefore, we are maintaining our Section 333 petition, and hope that we have not lost time pursuing this alternative.
