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.
