SUPPLEMENTARY INFORMATION: 

Discussion 

The Federal Office of Civil Aviation 

(FOCA), which is the aviation authority 

for Switzerland, has issued FOCA AD 

HB–2012–009, dated December 20, 2012 

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

correct an unsafe condition for the 

specified products. The MCAI states: 

This Airworthiness Directive (AD) is 

prompted due to the discovery of cracks in 

the engine mount fittings. The cracks are 

caused by stress corrosion. It is possible for 

stress corrosion cracks to occur on engine 

mount fittings initially made of aluminium 

alloy AA2024–T351. Later in production, the 

material specification was changed to 

aluminium alloy AA2124–T851 to decrease 

the risk of stress corrosion. The Part Number 

(P/N) of the engine mount fittings remained 

the same. 

Such a condition, if left uncorrected, could 

lead to failure of the engine mount fittings 

and possible failure of the engine attachment. 

In order to correct and control the 

situation, this AD requires a one-time check 

to identify the material specification and 

inspect those affected engine mount fittings 

that are made of aluminium alloy AA2024– 

T351. Any engine mount fittings found to be 

cracked must be reported to Pilatus prior to 

further flight. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

PILATUS Aircraft Ltd. has issued 

PILATUS PC–7 Service Bulletin No. 53– 

008, dated November 30, 2012. The 

actions described in this service 

information are intended to correct the 

unsafe condition identified in the 

MCAI. 

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 

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. 

Interim Action 

We consider this AD interim action. 

The type certificate holder is looking at 

repetitive inspection intervals to be 

done through the maintenance program. 

When these intervals are established, we 

may take additional rulemaking action 

to mandate the repetitive inspections. 

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 stress corrosion cracking in 

the engine mount area presents a critical 

safety of flight condition that requires 

inspection to ensure that the unsafe 

condition is mitigated. 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–2013–0025; 

Directorate Identifier 2012–CE–048– 

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. 

Costs of Compliance 

We estimate that this AD will affect 

15 products of U.S. registry. We also 

estimate that it would take about 7 

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 $0 per 

product. 

Based on these figures, we estimate 

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

be $8,925, or $595 per product. 

In addition, we estimate that any 

necessary follow-on actions would take 

about 10 work-hours and require parts 

costing $5,000, for a cost of $5,850 per 

product. We have no way of 

determining the number of products 

that may need these actions. 

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.

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model 737–300, 

737–400, 737–500, and 757–200 series 

airplanes. This AD was prompted by a 

report of damage caused by electrical 

arcing to the wires that connect seat 

electronics boxes (SEBs). This AD 

requires installing a new relay and 

doing certain wiring changes of the 

entertainment control switch. We are 

issuing this AD to prevent power from 

being supplied to passenger seats when 

the entertainment control switch is in 

the OFF position, which could cause an 

electrical shock hazard resulting in 

serious or fatal injury to maintenance 

personnel. 

DATES: This AD is effective February 22, 

2013. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of February 22, 2013.
