SUPPLEMENTARY INFORMATION: 

Discussion 

The Civil Aviation Safety Authority 

(CASA), which is the aviation authority 

for Australia, has issued AD No. AD/

GA8/7, dated September 2, 2013 

(referred to after this as ‘‘the MCAI’’), to 

correct an unsafe condition for the 

specified products. The MCAI states: 

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 do 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. 

This AD requires modifying the fuel 

system for ventilation and drainage. You 

may examine the MCAI on the Internet 

at http://www.regulations.gov by 

searching for and locating it in Docket 

No. FAA–2013–0823. 

Relevant Service Information 

GippsAero has issued Mandatory 

Service Bulletin SB–GA8–2012–96, 

Issue 4, dated August 12, 2013. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

FAA’s Determination and Requirements 

of This 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 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 

requires 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 integral sump tank in 

the fuel system is not suitably ventilated 

and drained to prevent the 

accumulation of flammable fluids or 

vapors, which could lead to a 

flammability issue. Therefore, we 

determined that notice and opportunity 

for public comment before issuing this 

AD are impracticable and that good 

cause exists for making this amendment 

effective in fewer than 30 days. 

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–2013–0823; 

Directorate Identifier 2013–CE–027– 

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 this AD 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.

Federal Register / Vol. 78, No. 186 / Wednesday, September 25, 2013 / Rules and Regulations 58873 

Costs of Compliance 

We estimate that this AD will affect 

35 products of U.S. registry. We also 

estimate that it will take about 3 workhours per product to do the fuel system 

ventilation and drainage modification 

requirement of this AD. The average 

labor rate is $85 per work-hour. 

Based on these figures, we estimate 

the cost of this AD on U.S. operators to 

be $8,925, or $255 per product. 

In addition, we estimate that it will 

take about 4 work-hours per product to 

do the cargo pod modification. The 

average labor rate is $85 per work-hour. 

Required parts would 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. 

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.

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for 

PILATUS AIRCRAFT LTD. Model PC– 

12/47E 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 

common grounding of both the pilot 

primary flight display (PFD) and the 

Electronic Standby Instrument System 

(ESIS). If the common ground fails both 

navigations systems could fail 

simultaneously, which could result in 

loss of control. We are issuing this AD 

to require actions to address the unsafe 

condition on these products. 

DATES: This AD is effective October 30, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of October 30, 2013.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on July 17, 2013 (78 FR 42723). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

During a design review of the electrical 

supply of navigation equipment installed on 

certain PC 12/47E aeroplanes, common 

grounding of the pilot Primary Flight Display 

(PFD) and the Electronic Standby Instrument 

System (ESIS) was identified. 

This condition, if not corrected, could lead, 

in case of failure of PFD and ESIS common 

ground, to simultaneous loss of more than 

one pilot flight information display and 

inhibition of flight parameter presentation, 

possibly resulting in reduced ability to 

control the aeroplane. 

To address this potentially unsafe 

condition, Pilatus Aircraft Ltd. introduced a 

modification in production to relocate the 

ESIS ground connection. This modification is 

available for affected in-service aeroplanes 

through Pilatus Aircraft Ltd Service Bulletin 

(SB) No 34–038. 

For the reasons described above, this 

AD requires relocation of the ESIS 

ground connection. The MCAI can be 

found in the AD docket on the Internet 

at http://www.regulations.gov/

#!documentDetail;D=FAA-2013-0610- 

0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (78 

FR 42723, July 17, 2013) 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 (78 FR 

42723, July 17, 2013) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (78 FR 42723, 

July 17, 2013). 

Costs of Compliance 

We estimate that this AD will affect 

230 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 $40 per 

product. 

Based on these figures, we estimate 

the cost of this AD on U.S. operators to 

be $106,950, or $465 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

We are issuing this rulemaking under 

the authority described in ‘‘Subtitle VII,

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.
