ACTION: Final rule. 

SUMMARY: We are superseding 

Airworthiness Directive (AD) 2013–24– 

14 for Diamond Aircraft Industries 

GmbH Models DA40 and DA40F 

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 the 

fatigue strength found in the aft main 

spar not ensuring unlimited lifetime 

structural integrity. We are issuing this 

AD to require actions to address the 

unsafe condition on these products. 

DATES: This AD is effective August 27, 

2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of August 27, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain other publications listed in

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 Diamond Aircraft Industries GmbH 

Model DA 40 airplanes. That NPRM was 

published in the Federal Register on 

April 14, 2014 (79 FR 20827), and 

proposed to supersede AD 2013–24–14, 

Amendment 39–17689 (78 FR 72568; 

December 3, 2013) (‘‘AD 2013–24–14’’). 

Since we issued AD 2013–24–14, the 

inspections required by AD 2013–24–14 

are tied to calendar time and the major 

structural inspection (MSI) identified in 

Chapter 5 of the airplane maintenance 

manual (AMM). This compliance time 

mirrors the mandatory continuing 

airworthiness information (MCAI) 

issued by the State of Design for these 

products. However, U.S. operators are 

not required to comply with the 

requirement to inspect before the next 

MSI since the Limitations in Chapter 4 

of the AMM are mandatory, and the MSI 

in Chapter 5 of the AMM is not 

mandatory. 

The NPRM proposed to correct an 

unsafe condition for the specified 

products and was based on MCAI 

originated by an aviation authority of 

another country. The MCAI states that: 

Structural fatigue testing of the DA 40 

aeroplane carried out for an extension of the 

Major Structural Inspection (MSI) interval 

has shown that the fatigue strength of the aft 

main spar in the cabin area does not ensure 

unlimited lifetime. 

This condition, if not corrected, could 

adversely affect the structural integrity of the 

aeroplane. 

Diamond Aircraft Industries (DAI) issued 

Mandatory Service Bulletin (MSB) 40–074/

MSB D4–094/MSB F4–028, including Work 

Instruction (WI) WI–MSB 40–074/WI–MSB 

D4–094/WI–MSB F4–028 (published as a 

single document), providing instructions to 

reinforce the aft main spar in the cabin area. 

For the reasons described above, this AD 

requires modification of the aft main spar in 

the cabin area. 

The MCAI can be found in the AD 

docket on the Internet at: http://www.

regulations.gov/#!documentDetail;D=

FAA-2014-0226-0002. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM (79 

FR 20827, April 14, 2014) 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 (79 FR 

20827, April 14, 2014) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (79 FR 20827, 

April 14, 2014). 

Costs of Compliance 

We estimate that this AD will affect 

747 products of U.S. registry. We also 

estimate that it will take about 6 workhours per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts will cost about $100 per 

product. 

Based on these figures, we estimate 

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

to be $455,670, or $610 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 

mstockstill on DSK4VPTVN1PROD with RULES

42648 Federal Register / Vol. 79, No. 141 / Wednesday, July 23, 2014 / Rules and Regulations 

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.

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Airbus Model A310 series airplanes. 

This AD was prompted by a report of an 

electrical arc and a hydraulic haze in 

the wheel bay of the left-hand main 

landing gear (MLG), possibly resulting 

from chafing between a hydraulic high 

pressure hose and electrical wiring of 

the green electrical motor pump (EMP). 

This AD requires modification of the 

electrical routing and replacement of the 

union elbows. We are issuing this AD to 

prevent chafing of hydraulic pressure 

hoses and electrical wiring of the green 

EMPs, which, in combination with a 

system failure, could cause an 

uncontrolled and undetected fire in the 

MLG bay. 

DATES: This AD becomes effective 

August 27, 2014. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 27, 2014.

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 certain Airbus Model A310 

series airplanes. The NPRM published 

in the Federal Register on February 3, 

2014 (79 FR 6102). The NPRM was 

prompted by a report of an electrical arc 

and a hydraulic haze in the wheel bay 

of the left-hand MLG, possibly resulting 

from chafing between a hydraulic high 

pressure hose and electrical wiring of 

the green EMP. The NPRM proposed to 

require modification of the electrical
