AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Proposed airworthiness standards for acceptance under the primary category rule; request for comments.

[[Page 40383]]

SUMMARY: This document announces the existence of and requests comments on proposed airworthiness design standards for acceptance of the Model Deland Travelaire airplane under FAA's rules on designation of applicable regulations for primary category aircraft.

DATES: Comments must be received on or before August 28, 1998.

ADDRESSES: Send all comments to the FAA, Standards Office, Small Airplane Directorate (ACE-110), Aircraft Certification Service, 601 East 12th Street, Kansas City, MO 64106.

FOR FURTHER INFORMATION CONTACT: Tim Smyth, Aerospace Engineer, Standards Office (ACE-111), Small Airplane Directorate, Aircraft Certification Service, FAA; telephone number (816) 426-6941, fax number (816) 426-2169.

SUPPLEMENTARY INFORMATION: Any person may obtain a copy of this information by contacting the person named above under FOR FURTHER INFORMATION CONTACT.

Comments Invited

We invite interested parties to submit comments on the proposed airworthiness standards to the address specified above. Commenters must identify the design standards (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) and submit comments to the address specified above. The FAA will consider all communications received on or before the closing date before issuing the final acceptance. The proposed airworthiness design standards and comments received may be inspected at the FAA, Small Airplane Directorate, Aircraft Certification Service, Standards Office (ACE-110), 1201 Walnut, Room 900, Kansas City, MO 64106, between the hours of 7:30 a.m. and 4:00 p.m. weekdays, except Federal holidays.

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., has 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.

The authority citation for the proposed 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.

Proposed 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, 21.24) with Department of Commerce Aeronautics Bulletin 7A, as amended October 1, 1934, as the design standard of the unmodified airplane structure and Transport Canada's TP10141E Ultralight (Sportplane) Design Standard will be used 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 July 8, 1998. Michael Gallagher, Manager, Small Airplane Directorate, Aircraft Certification Service.
