[Federal Register Volume 64, Number 53 (Friday, March 19, 1999)] [Rules and Regulations] [Pages 13501-13502] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 99-6755] ======================================================================= ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 21 Existence of Airworthiness Design Standards for Acceptance Under the Primary Category Rule AGENCY: Federal Aviation Administration (FAA), DOT. ACTION: Notice of availability of design standards. ----------------------------------------------------------------------- SUMMARY: This document announces the availability of airworthiness design standards for acceptance of the Model Deland Travelaire airplane under the FAA's rules on designation of applicable regulations for primary category aircraft. A notice requesting comments on the design standards was published July 29, 1998, and the comment period closed August 28, 1998. No comments were received on the design standards. [[Page 13502]] DATES: The design standards are effective March 9, 1999. ADDRESSES: Copies of the Department of Commerce Aeronautics Bulletin 7A, as amended October 1, 1934, and Transport Canada's TP10141E Ultralight (Sportplane) design standard may be obtained from the following: Small Airplace Directorate, Standards Office (ACE-110), Aircraft Certification Service, Federal Aviation Administration, 601 East 12th Street, Kansas City, MO 64106. FOR FURTHER INFORMATION CONTACT: Roger Chudy, Aerospace Engineer, Standards Office (ACE-112), Small Airplane Directorate, Aircraft Certification Service, FAA; telephone number (816) 426-6934, fax number (816) 426-2169. SUPPLEMENTARY INFORMATION: Background The ``primary'' category for aircraft was created specifically for the simple, low performance personal aircraft. Section 21.17(f) provides a means for applicants to propose airworthiness standards for their particular primary category aircraft. The FAA procedure establishing appropriate airworthiness standards includes reviewing and possibly revising the applicant's proposal, publication of the submittal in the Federal Register for public review and comment, and addressing the comments. After all necessary revisions, the standards are published as approved FAA airworthiness standards. Accordingly, the applicant, Orlando Helicopter Airways, Inc., submitted a request to the FAA to include the Department of Commerce Aeronautics Bulletin 7A, as amended October 1, 1934, as the design standard for the unmodified airplane structure and Transport Canada's TP10141E Ultralight (Sportplane) design standard for all modifications. The Department of Commerce Aeronautics Bulletin 7A was used in the original certification in March 1928 of the Curtiss Travel Aire 2000; therefore, the FAA considers this standard as continuing to be valid for the unmodified parts of the Deland Travelaire. On July 29, 1998, the Federal Register published an announcement of the proposed design standards and a request for comments. No comments were received to this proposal; therefore, this notice makes the design standards available for the Model Deland Travelaire airplane. Citation The authority citation for the airworthiness standards is as follows: Authority: 42 U.S.C. 7572; 49 U.S.C. 106(g), 40105, 40113, 44701-44702, 44707, 44709, 44711, 44713, 44715, 45303. Airworthiness Standards for Acceptance Under the Primary Category Rule The FAA is requiring 500 hours of operational aviation service history of the derivative V8 engine/wood-propeller combination on an airplane rather than the 200 hours offered by the applicant. The applicant has agreed to this position, therefore, the certification basis for the Deland Travelaire will be the Primary Category Rule (part 21, Sec. 21.24) with Department of Commerce Aeronautics Bulletin 7A, as amended October 1, 1934, as the design standard of the unmodified airplane structure and with Transport Canada's TP10141E Ultralight (Sportplane) Design Standard as the design standard for all modifications. Compliance with the acoustical standards of the latest amendment to 14 CFR part 36 at the time of certification will be required. Issued in Kansas City, Missouri on March 9, 1999.
