[Docket No. FAA-2013-0550]

Airworthiness Criteria: Proposed Airship Design Criteria for 
Lockheed Martin Aeronautics Model LMZ1M Airship

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of availability of proposed design criteria and request 
for comments.

-----------------------------------------------------------------------

SUMMARY: This notice announces the availability of and requests 
comments on the proposed design criteria for the Lockheed Martin 
Aeronautics model LMZ1M airship. On March 12, 2012 Lockheed Martin

SUPPLEMENTARY INFORMATION:

Comments Invited

    Interested persons are invited to comment on the proposed design 
criteria by submitting such written data, views, or arguments as they 
may desire. Commenters should identify the proposed design criteria on 
the Lockheed Martin Aeronautics model LMZ1M airship and submit 
comments, in duplicate, to the address specified above. All 
communications received on or before the closing date for comments will 
be considered by the Small Airplane Directorate before issuing the 
final design criteria.

Background

    On March 12, 2012 Lockheed Martin Aeronautics submitted an 
application for type certification for the model LMZ1M airship. The 
LMZ1M is a hybrid airship incorporating a number of advance features. 
The tri-lobed airship envelope has 1,285,000 cubic foot displacement 
incorporating four thrusters to allow thrust vectoring. Thrust 
vectoring and control surface motions are controlled through a vehicle 
management system using electronic fly by-wire controls. Rather than 
conventional landing gear, the LMZ1M uses air cushion landing system 
(ACLS) for landing and ground operations. The LMZ1M is a manned cargo 
lifting hybrid airship with a gondola accommodating eight passengers 
and two crewmembers and a large cargo bay, and external load 
capabilities.

Proposed Design Criteria

Applicable Airworthiness Criteria Under 14 CFR part 21

    The only applicable requirement for airship certification in the 
United States is FAA document ``FAA-P-8110-2, Airship Design Criteria 
(ADC),'' dated November 2, 1987 with Change 1, dated July 24, 1992 and 
Change 2, dated July 24, 1992. This document has been the basis of 
certification of airships in the United States for many years. The ADC 
is inadequate for an aircraft with the size and advanced features of 
the LMZ1M. Given the size and weight of the LMZ1M and in accordance 
with 14 CFR Part 21.17(b), the level of safety should be commensurate 
with other transport category aircraft. The ``Hybrid Certification 
Criteria (HCC) for Transport Category Hybrid Airships,'' Lockheed 
Martin Aeronautics Company Document Number 1008D0122 Rev. C dated 
January 31, 2013 was specifically developed for the LMZ1M. This 
criteria is based on ``FAA P-8110-2, Airship Design Criteria (ADC),'' 
the ``Transport Airship Requirements (TAR)'', dated March 2000, 14 CFR 
Part 29--Airworthiness Standards: Transport Category Rotorcraft and to 
a lesser extent 14 CFR Parts 23, 25, 33 and 35.

Certification Basis

    The Hybrid Certification Criteria (HCC) for Transport Category 
Hybrid Airships, Lockheed Martin Aeronautics Company Document Number 
1008D0122 Rev. C dated January 31, 2013.

    Issued in Kansas City, Missouri, on May 17, 2013.
