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 A318, A319, and A320 

series airplanes. This AD was prompted 

by a report of a torn out aspirator due 

to the aspirator interfering with the 

extrusion lip of the off-wing escape 

slide (OWS) enclosure during the initial 

stage of the deployment sequence. This 

AD requires modifying the OWS 

enclosures on both sides. We are issuing 

this AD to prevent both off-wing exits 

from being inoperative, which, during 

an emergency, would impair the safe 

evacuation of occupants, possibly 

resulting in personal injuries. 

DATES: This AD becomes effective 

October 22, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of October 22, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (SNPRM) to 

amend 14 CFR part 39 to include an AD 

that would apply to the specified 

products. That SNPRM was published 

in the Federal Register on June 11, 2012 

(77 FR 34283). That SNPRM proposed to 

correct an unsafe condition for the 

specified products. The MCAI states: 

One operator has reported a torn out 

aspirator following scheduled (for on-ground 

testing purposes) deployment of the Left 

Hand (LH) OWS [off-wing escape slide]. 

Investigations have revealed that the 

aspirator of the off-wing ramp/slide system 

interferes with the extrusion lip of the OWS 

enclosure during the initial stage of the 

deployment sequence. 

This condition, if not corrected, could 

result in both LH and Right Hand (RH) offwing exits being unserviceable which, during 

an emergency, would impair the safe 

evacuation of occupants, possibly resulting 

in personal injuries. 

For the reasons described above, this 

[European Aviation Safety Agency (EASA)] 

AD requires the modification of the OWS 

enclosures on both sides. 

* * * * * 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the SNPRM 

(77 FR 34283, June 11, 2012) or on the 

determination of the cost to the public. 

Conclusion 

We reviewed the available 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 SNPRM (77 FR 

34283, June 11, 2012) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the SNPRM (77 FR 34283, 

June 11, 2012). 

Costs of Compliance 

We estimate that this AD will affect 

about 694 products of U.S. registry. We 

also estimate that it will take about 14 

work-hours 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 $0 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of this AD 

to the U.S. operators to be $825,860, or 

$1,190 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. 

We prepared a regulatory evaluation 

of the estimated costs to comply with 

this AD and placed it in the AD docket. 

Examining the AD Docket 

You may examine the AD docket on 

the Internet at http:// 

www.regulations.gov; or in person at the 

Docket Operations office between 9 a.m. 

and 5 p.m., Monday through Friday,

contains the NPRM (76 FR 67625, 

November 2, 2011), SNPRM (77 FR 

34283, June 11, 2012), the regulatory 

evaluation, any comments received, and 

other information. The street address for

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the Bell 

Helicopter Textron Canada Limited 

(BHTC) Model 407 helicopters. This AD 

requires you to replace tailboomattachment hardware (attachment 

hardware), and perform initial and 

recurring determinations of the torque 

on the nuts of the tailboom-attachment 

bolts (bolts) at all four attachment 

locations. This AD was prompted by a 

review of the tailboom-attachment 

installation, which revealed that the 

torque value of the bolts specified in the 

BHTC Model 407 Maintenance Manual 

and applied during manufacturing was 

incorrect and exceeded the torque range 

recommended for the bolts. The actions 

required by this AD are intended to 

prevent an over-torque of a bolt, bolt 

failure, loss of the tailboom, and 

subsequent loss of control of the 

helicopter. 

DATES: This AD is effective October 22, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain document listed in this AD
