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

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.
