Airworthiness Directives; GA 8 Airvan (Pty) Ltd Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2013-19-12 for 
GA 8 Airvan (Pty) Ltd Models GA8 and GA8-TC320 airplanes. This AD 
results from mandatory continuing airworthiness information (MCAI) 
issued by an aviation authority of another country to identify and 
address an unsafe condition on an aviation product. The MCAI describes 
the unsafe condition as the fuel system integral sump tank not meeting 
FAA regulations. We are issuing this AD to require actions to address 
the unsafe condition on these products.

DATES: This AD is effective April 12, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 12, 
2018.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to GA 8 Airvan (Pty) Ltd 
Models GA8 and GA8-TC320 airplanes. That NPRM was published in the 
Federal Register on December 19, 2017 (82 FR 60128), and proposed to 
supersede AD 2013-19-12, Amendment 39-17594 (78 FR 58872, September 25, 
2013) (``AD 2013-19-12'').
    Since we issued AD 2013-19-12, the related service information has 
been amended to incorporate a modification

[[Page 9812]]

to ventilate the area around the integral sump tank.
    The NPRM proposed to address an unsafe condition for the specified 
products and was based on mandatory continuing airworthiness 
information (MCAI) originated by an aviation authority of another 
country. The MCAI states that:

    The GippsAero GA8 and GA8-TC 320 aircraft Mk II fuel system 
features an integral sump tank located in the floor structure 
forward of the co-pilot seat. The current configuration of the 
compartments adjacent to the Mk II sump tank does not meet the 
requirements of regulation 23.967(b) of the Federal Aviation 
Regulations of the United States of America in that they are not 
suitably ventilated and drained to prevent the accumulation of 
flammable fluids or vapours.
    Amendment 1 of this [CASA] directive mandates ventilation of the 
area around the integral sump tank as presented in SB-GA8-2012-96 
Issue 6 to meet the requirements of regulation 23.967(b) of the 
Federal Aviation Regulations of the United States of America.

The MCAI can be found in the AD docket on the internet at https://www.regulations.gov/document?D=FAA-2017-1166-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    We reviewed the relevant data and determined that air safety and 
the public interest require adopting this AD as proposed except for 
minor editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information

    We reviewed GippsAero Service Bulletin SB-GA8-2012-96, Issue 6, 
dated July 21, 2016. This service information describes procedures for 
modifying the fuel ventilation and drainage system. 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 of this AD.

Costs of Compliance

    We estimate that this AD will affect 47 products of U.S. registry. 
We also estimate that it will take about 3 work-hours per product to do 
fuel system ventilation and drainage modification requirement of this 
AD (this action is retained from AD 2013-19-12). The average labor rate 
is $85 per work-hour.
    Based on these figures, we estimate the cost of this portion of 
this AD on U.S. operators to be $11,985, or $255 per product.
    We also estimate that it will take about 4 work-hours per product 
to do the supplementary fuel ventilation modification requirement of 
this AD. The average labor rate is $85 per work-hour. Required parts 
will cost about $932 per product.
    Based on these figures, we estimate the cost of this portion of 
this AD on U.S. operators to be $59,784, or $1,272 per product.
    In addition, we estimate that it will take about 4 work-hours per 
product to do the cargo pod modification requirement of this AD (this 
action is retained from AD 2013-19-12). The average labor rate is $85 
per work-hour. Required parts will cost about $1,000 per product, for a 
cost of $1,340 per product. We have no way of determining the number of 
products that may need this action.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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 AD will not have federalism implications 
under Executive Order 13132. This AD will 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 AD:
    (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.
