Airworthiness Directives; GA 8 Airvan (Pty) Ltd Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for GA 
8 Airvan (Pty) Ltd Model GA8 and Model GA8-TC320 airplanes. This 
proposed AD results from mandatory continuing airworthiness information 
(MCAI) originated by an aviation authority of another country to 
identify and correct an unsafe condition on an aviation product. The 
MCAI describes the unsafe condition as a design change to the fuselage 
strut pick up ribs No. 5 and 6 that requires a reduced life limit. We 
are issuing this proposed AD to require actions to address the unsafe 
condition on these products.

DATES: We must receive comments on this proposed AD by September 26, 
2019.

Discussion

    The Civil Aviation Safety Authority (CASA), which is the aviation 
authority for Australia, has issued AD No. AD/GA8/10, dated October 17, 
2018 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    Airworthiness Limitations are promulgated in the GippsAero 
Service Manual [Airworthiness Limitations Section] ALS Chapter 4 
Airworthiness Limitations. The change to the Airworthiness 
Limitations by GippsAero on 15 May 2018 was the result of the 
manufacturer changing the design of the fuselage strut pick up ribs 
no. 5 and 6. The revised rib designs have a different life 
limitation to the earlier rib designs. These Airworthiness 
Limitations are approved by CASA and non-compliance with these 
limitations could result in an unsafe condition developing. The 
Service Manual Chapter 4 Airworthiness Limitations dated 15 May 2018 
are mandatory in Australia however foreign National Aviation 
Authorities may not automatically require revision of service 
manuals without the issue of this AD.

    While the U.S. type certificate holder is GA8 Airvan C/O GippsAero, 
service manuals for the GA8 and GA8-TC320 model airplanes are issued by 
GippsAero.
    You may examine the MCAI on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2019-
0615.

Related Service Information Under 1 CFR Part 51

    The FAA has reviewed the following updated service information from 
the aircraft service manuals for Model GA8 and Model GA8-TC320 
airplanes:
     C01-00-04, Chapter 4, Airworthiness Limitations, dated May 
14, 2018, for the Model GA8; and
     C01-00-06, Chapter 4, Airworthiness Limitations, dated May 
14, 2018, for the Model GA8-TC 320.
    This service information establishes life limits for certain 
fuselage strut pick up ribs No. 5 and 6. This service information is 
reasonably available because the interested parties have access to it 
through their normal course of business or by the means identified in 
the ADDRESSES section.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with this State of Design Authority, they 
have notified us of the unsafe condition described in the MCAI and 
service information referenced above. We are proposing this AD because 
we evaluated all information and determined the unsafe condition exists 
and is likely to exist or develop on other products of the same type 
design.

Costs of Compliance

    We estimate that this proposed AD will affect 30 products of U.S. 
registry. We also estimate that it would take about 1 work-hour per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour.
    Based on these figures, we estimate the cost of this proposed AD on 
U.S. operators to be $2,550, or $85 per product.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I, section 106, describes the 
authority of the FAA Administrator. ``Subtitle VII: Aviation 
Programs,'' describes in more detail the scope of the Agency's 
authority.
    We are issuing this rulemaking under the authority described in 
``Subtitle VII, Part A, Subpart III, Section 44701: General 
requirements.'' Under that section, Congress charges the FAA with 
promoting safe flight of civil aircraft in air commerce by prescribing 
regulations for practices, methods, and procedures the Administrator 
finds necessary for safety in air commerce. This regulation is within 
the scope of that authority because it addresses an unsafe condition 
that is likely to exist or develop on products identified in this 
rulemaking action.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to small airplanes, gliders, 
balloons, airships, domestic business jet transport airplanes, and 
associated appliances to the Director of the Policy and Innovation 
Division.

Regulatory Findings

    We determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would not 
have a substantial direct effect on the States, on the relationship 
between the national Government and the States, or on the distribution 
of power and responsibilities among the various levels of government.
    For the reasons discussed above, I certify this proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
