Department of Transportation Federal Aviation Administration • 14 CFR Part 27 • [Docket No. FAA-2020-1011; Notice No. 27-051-SC] AGENCY: Federal Aviation Administration (FAA), DOT. ( printed page 14527) ACTION: Final special conditions. SUMMARY: These special conditions are issued for the Leonardo S.p.A. (Leonardo) Model A119 and AW119 MKII helicopters. These helicopters as modified by AgustaWestland Philadelphia Corporation (AWPC) will have a novel or unusual design feature when compared to the state of technology envisioned in the airworthiness standards for helicopters. This design feature is the optional closed circuit refueling receiver (CCRR). The applicable airworthiness regulations do not contain adequate or appropriate safety standards for this design feature. These special conditions contain the additional safety standards that the Administrator considers necessary to establish a level of safety equivalent to that established by the existing airworthiness standards. DATES: Effective April 16, 2021. FOR FURTHER INFORMATION CONTACT: Rao Edupuganti, Dynamic Systems Section, AIR-627, Policy and Innovation Division, Aircraft Certification Service, 10101 Hillwood Parkway, Fort Worth, Texas 76177; telephone (817) 222-4389. SUPPLEMENTARY INFORMATION: Background On January 30, 2020, AWPC applied for a supplemental type certificate to install an optional CCRR in the Leonardo Model A119 and AW119 MKII helicopters. The general configuration and the principles of construction of these helicopters will not be changed by the modifications. These helicopters are 14 CFR part 27 normal category helicopters powered by turboshaft engines, with a 7-passenger maximum capacity and minimum crew of one pilot and a maximum weight of 5,997 lb (2,720 kg) and 6,283 lb (2,850 kg), respectively. The total useable fuel capacity of the Leonardo Model A119 and AW119 MKII helicopters is 157.0 U.S. gallons distributed within the fuel tanks. Both helicopter models are powered by one Pratt & Whitney Canada Inc. PT6B-37A turboshaft engine. Part 27 does not contain requirements for pressure refueling for normal category helicopters. Title 14 CFR 29.979, amendment 29-12, provides these requirements for transport category helicopters. Accordingly, these special conditions are based on § 29.979 to provide requirements for the inclusion of the optional CCRR on the Leonardo Model A119 and AW119 MKII helicopters. Type Certification Basis Under the provisions of 14 CFR 21.101, AWPC must show that the Leonardo Model A119 and AW119 MKII helicopters, as changed, continue to meet the applicable provisions of the regulations listed in Type Certificate No. H7EU or the applicable regulations in effect on the date of application for the change. The regulations adopted by reference in the type certificate are commonly referred to as the “original type certification basis.” The certification basis also includes certain special conditions, exemptions, or later amended sections of the applicable part that are not relevant to these special conditions. The Administrator has determined that the applicable airworthiness regulations do not contain adequate or appropriate safety standards for the Leonardo Model A119 and AW119 MKII helicopters because of a novel or unusual design feature. Therefore, special conditions are prescribed under the provisions of § 21.16. Special conditions are initially applicable to the model for which they are issued. Should the applicant apply for a supplemental type certificate…
