Airworthiness Directives; GA 8 Airvan (Pty) Ltd Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are revising an airworthiness directive (AD) 2015-06-02 for 
GA 8 Airvan (Pty) Ltd Model GA8-TC320 airplanes. This AD results from 
mandatory continuing airworthiness information (MCAI) issued 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 missing required engine mount fire seal washers, which 
could reduce the engine retention capability in the event of a fire. We 
are issuing this AD to require actions to address the unsafe condition 
on these products.

DATES: This AD is effective August 20, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain other publication listed in this AD as of April 
24, 2015 (80 FR 14810, March 20, 2015).

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to add an AD that would apply to GA 8 Airvan (Pty) Ltd Model 
GA8-TC320 airplanes. The NPRM was published in the Federal Register on 
April 17, 2015 (74 FR 21193), and proposed to revise AD 2015-06-02, 
Amendment 39-18120 (80 FR 14810; March 20, 2015).
    The NPRM proposed to correct an unsafe condition for the specified 
products and was based on mandatory continuing airworthiness 
information originated by an airworthiness authority of another 
country. The MCAI states that:

    A recent review of the engine mount installation on the GA8-TC 
320 aircraft has highlighted the omission of engine mount fire seal 
washers during the assembly process.
    The current engine mount configuration does not meet the 
certification basis for the aircraft, specifically regulation 23.865 
of the Federal Aviation Regulations of the United States of America, 
where engine mounts located in designated fire zones are required to 
be suitably shielded so that they are capable of withstanding the 
effects of a fire.
    The Gippsland Aeronautics GA8-TC 320 aircraft require the 
installation of an approved steel washer at each of the engine mount 
locations to address a potential risk of reduced engine retention 
capability in the event of a fire.
    This AD, AD/GA8/8 Amdt 1, amends the applicability statement to 
be inclusive of the affected aircraft serial number range.
    The MCAI can be found in the AD docket on the Internet at: http://www.regulations.gov/#!documentDetail;D=FAA-2014-1123-0007.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (74 FR 21193, April 17, 
2015) 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 the 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 (74 FR 21193, April 17, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (74 FR 21193, April 17, 2015).

Relative Service Information Under 1 CFR Part 51

    We reviewed GippsAero Mandatory Service Bulletin SB-GA8-2014-115, 
Issue 1, dated October 6, 2014. The service bulletin describes 
procedures for inspecting the orientation of the engine isolator mounts 
to verify proper installation, re-installing if necessary, and 
installing steel washers on the forward side of each side of the engine 
isolator mounts. 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 13 products of U.S. registry. 
We also estimate that it would take about 5 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Required parts would cost about $10 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

[[Page 42011]]

that is likely to exist or develop on products identified in this 
rulemaking action.

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.

    You may examine the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2014-
1123; or in person at the Docket Management Facility between 9 a.m. and 
5 p.m., Monday through Friday, except Federal holidays. The AD docket 
contains the NPRM, the regulatory evaluation, any comments received, 
and other information. The street address for the Docket Office 
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will 
be available in the AD docket shortly after receipt.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

2. The FAA amends Sec.  39.13 by removing Amendment 39-18120 (80 FR 
14810, March 20, 2015), and adding the following new AD:

2015-06-02 R1 GA 8 Airvan (Pty) Ltd: Amendment 39-18209; Docket No. 
FAA-2014-1123; Directorate Identifier 2014-CE-037-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective August 20, 
2015.

(b) Affected ADs

    This AD revises AD 2015-06-02, Amendment 39-18120 (80 FR 14810; 
March 20, 2015).

(c) Applicability

    This AD applies to GA 8 Airvan (Pty) Ltd GA8-TC320 airplanes,

    This AD was prompted by 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 missing required 
engine mount fire seal washers, which could reduce the engine 
retention capability in the event of a fire. We are issuing this AD 
to revise the applicable airplane serial numbers and to detect and 
correct the omission of steel washers at each isolator mount 
location, which, if not corrected, could result in reduced engine 
retention capability in the event of a fire.

(f) Actions and Compliance

    Unless already done, comply with this AD within the compliance 
times specified in paragraphs (f)(1) through (f)(3) of this AD:
    (1) Within the next 300 hours time-in-service after April 24, 
2015 (the effective date retained from AD 2015-22-14) or within the 
next 12 months after April 24, 2015 (the effective date retained 
from AD 2015-22-14), whichever occurs first, inspect the orientation 
of the engine isolator mounts to verify that the mounts have been 
installed properly following the Accomplishment Instructions in 
GippsAero Mandatory Service Bulletin SB-GA8-2014-115, Issue 1, dated 
October 6, 2014.
    (2) Before reinstalling the engine isolator mounts following the 
inspection required in paragraph (f)(1) of this AD, before further 
flight, install a part number J-2218-61 steel washer on the forward 
side of each of the four engine isolator mounts, following the 
Accomplishment Instructions in GippsAero Mandatory Service Bulletin 
SB-GA8-2014-115, Issue 1, dated October 6, 2014.
    (3) If during the inspection required in paragraph (f)(1) of 
this AD, any of the engine isolator mounts are found to not comply 
with the specifications found in the Accomplishment Instructions of 
GippsAero Mandatory Service Bulletin SB-GA8-2014-115, Issue 1, dated 
October 6, 2014, before further flight, re-install the isolators to 
the correct orientation, or if damage is found, replace with 
airworthy parts.
