FAA Order JO 7210.3, Chapter 5, Section 5, 14 CFR Part 91, UAS Operations. 2. Generally, UAS cannot comply with certain 14 CFR regulations originally written for a manned aircraft environment and therefore require relief. UAS operators obtain relief from the requirements of these regulations through exemptions, waivers, and deviations. The relief document lists conditions and limitations which provide a level of safety at least equal to that provided by the rule from which relief is needed. Additionally, UAS operators must obtain a Certificate of Waiver or Authorization (COA) from the FAA Air Traffic Organization (ATO). Applicants for 14 CFR Part 135 certification should begin the process by contacting their local FAA Flight Standards District Office (FSDO). NOTE- Examples of such regulations include requirements for the provision of seat belts for aircrew and passengers, on-board carriage of an aircraft manual, etc. (a) Application for a 14 CFR Part 135 certificate. Application for a 14 CFR Part 135 air carrier certificate for UAS operations uses the same process as that for manned 14 CFR Part 135 applicants. For information on how to apply for an air carrier certificate issued under 14 CFR Part 135, see the FAA 14 CFR Part 135 Air Carrier and Operator Certification website.

(b) Advisory Circular 120-49A, Parts 121 and 135 Certification is available to aid an applicant in Part 135 certification. REFERENCE- AC 120-49, Parts 121 and 135 Certification. (c) Exemptions and COAs. Additional information on how to petition for an exemption and obtain a COA is available on the FAA Advanced Operations website. NOTE- The FAA"s Advanced Operations website may be reviewed at: https://www.faa.gov/uas/advanced_operations/. b. 14 CFR Part 137, Agricultural Aircraft Operations: 1. Civil and public operators of UAS may conduct agricultural aircraft operations, as defined in 14 CFR Part 137.3, Definition of Terms. These operations must be conducted in accordance with an agricultural aircraft operator certificate issued under 14 CFR Part 137, and an exemption from certain federal aviation regulations granted under 14 CFR Part 11, General Rulemaking Procedures. Operators of sUAS, weighing less than 55 pounds MGOW may conduct agricultural aircraft operations under 14 CFR Part 107, sUAS, and 14 CFR Part 137. Operators of large UAS, weighing 55 pounds MGOW or more may conduct agricultural aircraft operations under 14 CFR Parts 91, UAS operations, and 14 CFR Part 137.

Generally, as is the case with 14 CFR Part 135 standard cargo operations, UAS cannot comply with certain 14 CFR regulations, and therefore require relief. For example, sUAS require relief from carriage of hazardous material (107.36), aircraft certification (137.19(d)), carriage of agricultural aircraft operator certificate (137.33(a)), and, for large UAS, certain aircraft airworthiness requirements (14 CFR Parts 21 and 91). UAS operators obtain relief from the requirements of these regulations through an exemption. The exemption lists conditions and limitations which provide a level of safety at least equal to that provided by the rule. Additionally, large UAS operators must obtain a COA from the FAA ATO.
