ACTION: Issuance of final airworthiness criteria. SUMMARY: The FAA announces the special class airworthiness criteria for the 3DRobotics Government Services Model 3DR-GS H520-G unmanned aircraft (UA). This document sets forth the airworthiness criteria the FAA finds to be appropriate and applicable for the UA design. DATES: These airworthiness criteria are effective April 18, 2022. FOR FURTHER INFORMATION CONTACT: Christopher J. Richards, Emerging Aircraft Strategic Policy Section, AIR-618, Strategic Policy Management Branch, Policy and Innovation Division, Aircraft Certification Service, Federal Aviation Administration, 6020 28th Avenue South, Room 103, Minneapolis, MN 55450, telephone (612) 253-4559. SUPPLEMENTARY INFORMATION: Background 3DRobotics Government Services (3DR) applied to the FAA on May 1, 2019, for a special class type certificate under Title 14, Code of Federal Regulations (14 CFR) 21.17(b) for the Model 3DR-GS H520-G unmanned aircraft system (UAS). The Model 3DR-GS H520-G consists of a rotorcraft UA and its associated elements (AE) including communication links and components that control the UA. The Model 3DR-GS H520-G UA has a maximum gross takeoff weight of five pounds. It is approximately 20 inches in width, 18 inches in length, and 12 inches in height. The Model 3DR-GS H520-G UA uses battery-powered electric motors for vertical takeoff, landing, and forward flight. The UA may be manually operated or may rely on high levels of automation. The UAS may include multiple UA operated by a single pilot, up to a ratio of 20 UA to 1 pilot. 3DR anticipates operators will use the Model 3DR-GS H520-G for inspection or surveying of critical infrastructure. The proposed concept of operations (CONOPS) for the Model 3DR-GS H520-G identifies a maximum operating altitude of 400 feet above ground level (AGL), a maximum cruise speed of 33 knots (38 mph), operations within visual line of sight of the pilot, operations at night, and operations in sparsely populated areas. 3DR has not requested type certification for flight into known icing for the Model 3DR-GS H520-G. The FAA issued a notice of proposed airworthiness criteria for the 3DR-GS H520-G UAS, which published in the Federal Register on November 24, 2020 (85 FR 74926). Summary of Changes From the Proposed Airworthiness Criteria Based on the comments received, these final airworthiness criteria reflect the following changes, as explained in more detail under Discussion of Comments: A new section containing definitions; revisions to the CONOPS requirement; changing the term “critical part” to “flight essential part” in D&R.135; changing the basis of the durability and reliability testing from population density to limitations prescribed for the operating environment identified in the applicant's CONOPS per D&R.001; and, for the demonstration of certain required capabilities and functions as required by D&R.310. Additionally, the FAA re-evaluated its approach to type certification of low-risk UA using durability and reliability testing. Safe UAS operations depend and rely on both the UA and the AE. As explained in FAA Memorandum AIR600-21-AIR-600-PM01, dated July 13, 2021, the FAA has revised the airworthiness criteria to define a boundary between the UA type certification and subsequent…
