AD 2015-06-02 R2

We are adopting a new airworthiness directive (AD) for GA 8 Airvan (Pty) Ltd Model GA8-TC320 airplanes. This AD revises AD 2015-06- 02 R1, which required inspection to detect and correct the omission of steel washers at each isolator mount location. This AD retains the actions of AD 2014-06-02 R1 but corrects the AD number in the parenthetical of the compliance time in paragraph (f)(1) of the AD. This AD was prompted by reports of 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.

Final rule; request for comments

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

0 1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13 [Amended]

0 2. The FAA amends Sec. 39.13 by removing airworthiness directive (AD) 2015-06-02 R1 (80 FR 42010, July 16, 2015) and adding the following new AD:

2015-06-02 R2 GA 8 Airvan (Pty) Ltd: Amendment 39-18308; Docket No. FAA-2014-1123; Directorate Identifier 2014-CE-037-AD.

(a) Effective Date

This airworthiness directive (AD) becomes effective December 3, 2015.

(b) Affected ADs

This AD replaces AD 2015-06-02 R1, Amendment 39-18209 (80 FR 42010, July 16, 2015) (``AD 2015-06-02 R1'').

(c) Applicability

This AD applies to GA 8 Airvan (Pty) Ltd GA8-TC320 airplanes, all serial numbers up to and including GA8-TC 320-14-205, certificated in any category.

(d) Subject

Air Transport Association of America (ATA) Code 71: Power Plant.

(e) Reason

AD 2015-06-02, Amendment 39-18120 (80 FR 14810, March 20, 2015) (``AD 2015-06-02'') 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 issued AD 2015-06-02 R1, Amendment 39-18209 to retain the actions of AD 2015- 06-02 and to revise the applicable airplane serial numbers. We are issuing this AD to correct the AD number in the parenthetical of the compliance time in paragraph (f)(1) of the AD 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 2015-06-02 and AD 2015-06- 02 R1) or within the next 12 months after April 24, 2015 (the effective date retained from AD 2015-06-02 and AD 2015-06-02 R1), 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

[[Page 66415]]

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.

(g) Other FAA AD Provisions

The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, Standards Office, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. Send information to ATTN: Doug Rudolph, Aerospace Engineer, FAA, Small Airplane Directorate, 901 Locust, Room 301, Kansas City, Missouri 64106; telephone: (816) 329-4059; fax: (816) 329-4090; email: doug.rudolph@faa.gov. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.
(2) Airworthy Product: For any requirement in this AD to obtain corrective actions from a manufacturer or other source, use these actions if they are FAA-approved. Corrective actions are considered FAA-approved if they are approved by the State of Design Authority (or their delegated agent). You are required to assure the product is airworthy before it is returned to service.

Discussion

On July 7, 2015, we issued AD 2015-06-02 R1, Amendment 39-18209 (80 FR 42010; July 16, 2015). That AD required actions intended to address an unsafe condition on GA 8 Airvan (Pty) Ltd Model GA8-TC320 airplanes and was based on mandatory continuing airworthiness information (MCAI) originated by the Civil Aviation Safety Authority (CASA), which is the aviation authority for Australia. The MCAI (AD No. AD/GA8/8, Amdt 1, dated March 26, 2015) states:

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.

You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2011-0127.
Since we issued AD 2015-06-02 R1, it was determined that the incorrect retained AD number was referenced in the parenthetical of the compliance time in paragraph (f)(1) of the AD. To avoid any confusion, this AD revises AD 2015-06-02 R1 to correct this reference.

Related 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.

FAA's Determination and Requirements of the 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

[[Page 66414]]

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 issuing this AD because we evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design.

FAA's Determination of the Effective Date

An unsafe condition exists that allows for the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because the change does not affect compliance and the actions have already been proposed in prior rulemaking actions. Therefore, we determine that notice and opportunity for public comment before issuing this AD are impraticable.

Comments Invited

This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ``Docket No. FAA-2014-1123; Directorate Identifier 2014-CE-037-AD'' at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend thisAD because of those comments.
We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about 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 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 that 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.
