Airworthiness Directives; GA 8 Airvan (Pty) Ltd Airplanes

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

ACTION: Final rule.

––––––––––––––––––––––––––––––––––

SUMMARY: We are adopting a new airworthiness directive (AD) 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 April 24, 2015.

The Director of the Federal Register approved the incorporation by reference of a certain 

publication listed in the AD as of April 24, 2015.

ADDRESSES: 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 Document Management 

Facility, U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor,

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 airplane. The NPRM was published in the 

Federal Register on January 6, 2015 (80 FR 419). The NPRM proposed to correct 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:

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.

The MCAI can be found in the AD docket on the Internet at: 

http://www.regulations.gov/#!documentDetail;D=FAA-2014-1123-0002.

Comments

We gave the public the opportunity to participate in developing this AD. We received no 

comments on the NPRM (80 FR 419, January 6, 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 (80 FR 419, January 6, 2015) 

for correcting the unsafe condition; and

• Do not add any additional burden upon the public than was already proposed in the NPRM 

(80 FR 419, January 6, 2015).

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 GippsAero Mandatory Service Bulletin SB-GA8-2014-115, Issue 1, dated October 6, 

2014 describes procedures for inspecting the orientation of the engine isolator mounts to verify
3

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; see

ADDRESSES for ways to access this service information.

Costs of Compliance

We estimate that this proposed 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.

Based on these figures, we estimate the cost of this AD on U.S. operators to be $5,655, or $435 

per product.

According to the manufacturer, all 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.

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.

Examining the AD Docket

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.
