AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

BAE SYSTEMS (OPERATIONS) 

LIMITED Model BAe 146 series 

airplanes and Model Avro 146–RJ series 

airplanes. This AD was prompted by 

hydraulic pipe ruptures in the center of 

the cabin resulting in passengers being 

contaminated with hydraulic fluid. This 

AD requires installing a hydraulic fluid 

containment system. We are issuing this 

AD to prevent harmful or hazardous 

concentrations of hydraulic fluid or 

hydraulic vapor from entering the 

passenger compartment, possibly 

resulting in injury to the passengers. 

DATES: This AD becomes effective 

December 5, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of December 5, 2012.

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 June 21, 2012 (77 FR 37340). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The Mandatory Continuing 

Airworthiness Information (MCAI) 

states: 

Cases of hydraulic pipe ruptures in the 

centre of the cabin of BAe 146 aeroplanes 

have been reported, which have resulted in 

the passengers being contaminated with 

hydraulic fluid. The results of the 

investigations have shown that the pipe 

failures were caused by a combination of 

seam welded pipes, bends in the pipe runs 

with small bend radii and fatigue damage 

due to pressure variations. 

This condition, if not corrected, could lead 

to harmful or hazardous concentrations of 

hydraulic fluid or hydraulic vapour entering 

the passenger compartment, possibly 

resulting in injury to the occupants. 

For the reasons described above, this 

[European Aviation Safety Agency] AD 

requires the installation of a flexible 

envelope around the hydraulic pipe group 

where the failures have occurred to capture 

and contain any fluid escaping from a burst 

pipe and channel it below floor level into the 

forward cargo bay. 

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 

considered the comment received. 

Request for Exclusion of Airtankers 

Neptune Aviation Services requested 

a change in the text of paragraph (c) 

‘‘Applicability,’’ of the NPRM (77 FR 

37340, June 21, 2012) to include an 

‘‘exemption’’ for an airplane operated as 

an ‘‘airtanker,’’ which does not carry 

passengers. 

We partially agree with the request to 

change the text in paragraph (c) of this 

AD. We disagree with using the term 

‘‘airtanker’’; however, we have revised 

mstockstill on DSK4VPTVN1PROD with RULES

65802 Federal Register / Vol. 77, No. 211 / Wednesday, October 31, 2012 / Rules and Regulations 

paragraph (c) to include an exception 

for airplanes in a non-passenger 

configuration. 

Conclusion 

We reviewed the available data, 

including the comment received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously, 

except for minor editorial changes. We 

have determined that these changes: 

• Are consistent with the intent that 

was proposed in the NPRM (77 FR 

37340, June 21, 2012) for correcting the 

unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 37340, 

June 21, 2012). 

Costs of Compliance 

We estimate that this AD will affect 1 

product of U.S. registry. We also 

estimate that it will take about 8 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 $5,079 

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 

$5,759. 

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, 

except Federal holidays. The AD docket 

contains the NPRM (77 FR 37340, June 

21, 2012), the regulatory evaluation, any 

comments received, and other 

information. The street address for the 

Docket Operations office (telephone 

(800) 647–5527) is in the ADDRESSES

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

The Boeing Company Model MD–90–30 

airplanes. This AD was prompted by 

reports of fatigue cracks found in 

Stringer 11 at the outboard flap, inboard 

drive hinge at Station Xrs=164.000. This 

AD requires repetitive inspections for 

cracks in Stringer 11, and a splice repair 

if necessary; and repetitive post-repair 

inspections, and repair if necessary. We 

are issuing this AD to detect and correct 

such cracking, which could result in the 

wing structure not supporting the limit 

load condition, which could lead to loss 

of the structural integrity of the wing. 

DATES: This AD is effective December 5, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD

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 published in the Federal 

Register on August 1, 2012 (77 FR 

45515). That NPRM proposed to require 

repetitive inspections for cracks in 

Stringer 11, and a splice repair if 

necessary; and repetitive post-repair 

inspections, and repair if necessary. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

have considered the comment received. 

Boeing supports the NPRM (77 FR 

45515, August 1, 2012). 

Conclusion 

We reviewed the relevant data, 

considered the comment received, 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 (77 FR 

45515, August 1, 2012) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (77 FR 45515, 

August 1, 2012). 

Costs of Compliance 

We estimate that this AD affects 52 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD:
