Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated 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: 

In the door 2 area, the hat-racks are 

supplied with a basic wire harness which 

includes ‘‘Oxygen Masks’’ activation. 

In case of a monument installation, the 

respective non-used hat-rack connections 

between monument and outer skin are put on 

stow. It was noticed in production, that the 

distance between the stowed wire harness 

and the monument could be too small. This 

condition, if not corrected, could lead to the 

short circuit of wires dedicated to oxygen, 

which, in case of emergency, could result in 

a large number of passenger oxygen masks 

not being supplied with oxygen, possibly 

causing personal injuries. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective June 

25, 2010. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of June 25, 2010.

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 October 19, 2009 (74 FR 

53440). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 


cprice-sewell on DSK8KYBLC1PROD with RULES
28476 Federal Register / Vol. 75, No. 98 / Friday, May 21, 2010 / Rules and Regulations 

In the door 2 area, the hat-racks are 

supplied with a basic wire harness which 

includes ‘‘Oxygen Masks’’ activation. 

In case of a monument installation, the 

respective non-used hat-rack connections 

between monument and outer skin are put on 

stow. It was noticed in production, that the 

distance between the stowed wire harness 

and the monument could be too small. This 

condition, if not corrected, could lead to the 

short circuit of wires dedicated to oxygen, 

which, in case of emergency, could result in 

a large number of passenger oxygen masks 

not being supplied with oxygen, possibly 

causing personal injuries. 

For the reasons described above, this AD 

requires the modification of the hat rack 

connectors on stow, and the rerouting of the 

associated wire harness in case of monument 

installed in door 2 area. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued Mandatory Service 

Bulletin A340–92–4073, Revision 02, 

dated October 12, 2009. Revision 02 

includes the following changes: 

• Adds a note stating that the 

modification of cable harness 5302VB/ 

5303VB is necessary only if the cable is 

installed; and 

• Makes minor text corrections. 

We referred to Airbus Mandatory 

Service Bulletin A340–92–4073, 

Revision 01, dated January 13, 2009, as 

the appropriate source of service 

information for accomplishing the 

actions specified in the NPRM (for 

Model A340–300 series airplanes). 

We have revised paragraphs (f)(1), 

(f)(2), and (h) of this AD to cite Airbus 

Mandatory Service Bulletin A340–92– 

4073, Revision 02, dated October 12, 

2009. We have added paragraph (f)(3) of 

this AD to give credit for 

accomplishment of the actions done in 

accordance with the Airbus Mandatory 

Service Bulletin A340–92–4073, 

Revision 01, dated January 13, 2009; or 

Airbus Mandatory Service Bulletin 

A340–92–4073, dated July 10, 2008. 

Airbus has also issued Mandatory 

Service Bulletin A330–92–3070, 

Revision 02, dated August 19, 2009. 

Revision 02 includes the following 

changes: 

• Removes airplanes from the 

effectivity; 

• Makes minor text changes; 

• Changes the location of wire 

harness 5315VB/5316VB in Figure 2; 

and 

• Adds a note stating that 

modification of wire harness 5302VB/ 

5303VB is only necessary if installed. 

We referred to Airbus Mandatory 

Service Bulletin A330–92–3070, 

Revision 01, dated January 12, 2009, as 

the appropriate source of service 

information for accomplishing the 

actions specified in the NPRM (for 

Model A330–200 and A330–300 series 

airplanes). 

We have revised paragraphs (f)(1), 

(f)(2), and (h) of this AD to cite Airbus 

Mandatory Service Bulletin A330–92– 

3070, Revision 02, dated August 19, 

2009. We have added paragraph (f)(3) to 

give credit for accomplishment of the 

actions done in accordance with Airbus 

Mandatory Service Bulletin A330–92– 

3070, dated July 10, 2008; or Airbus 

Mandatory Service Bulletin A330–92– 

3070, Revision 01, dated January 12, 

2009. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

considered the comments received. 

Support for the NPRM 

Air Line Pilots Association (ALPA), 

International supports the NRPM. 

Request To Extend Compliance Time 

Northwest Airlines (NWA) requests 

that we extend the proposed compliance 

time for the modification specified in 

paragraph (f) of the NPRM from within 

24 months to within 24 months for 

locations where monuments are 

installed, and for other specified 

locations, to within 72 months or at the 

time of a new monument installation, 

whichever occurs first. NWA explains 

that its Model A330 airplanes have a 

monument installed in only one of the 

four locations specified in the service 

information, and that according to 

paragraph (e) of the NPRM, the unsafe 

condition only exists at locations where 

there is a monument installed. NWA 

reasons that allowing a later compliance 

time for those areas without monuments 

would allow operators to accomplish 

the required actions while access is 

available to the monuments during 

normally scheduled maintenance. 

We do not agree to extend the 

compliance time specified in paragraph 

(f) of the final rule for door-2 locations 

without an installed monument. This 

AD requires modification of non-used 

hat-rack connections between the 

monument and outer skin only for door2 areas where a monument is installed, 

as specified in the Accomplishment 

Instructions of Airbus Mandatory 

Service Bulletin A330–92–3070, 

Revision 02, dated August 19, 2009; or 

Airbus Mandatory Service Bulletin 

A340–92–4073, Revision 02, dated 

October 12, 2009; which ensures the 

clearance between the wire harnesses 

and the monument. The service 

bulletins also specify airplane 

configurations and the actions for each 

configuration. There are no actions 

required for those door-2 areas without 

monuments. We have clarified 

paragraph (f)(1) of this AD by adding the 

phrase ‘‘for airplanes on which a 

monument is installed in the door-2 

area, as specified in Airbus Mandatory 

Service Bulletin A330–92–3070, 

Revision 02, dated August 19, 2009; or 

Airbus Mandatory Service Bulletin 

A340–92–4073, Revision 02, dated 

October 12, 2009.’’ 

Request To Revise Proposed Costs of 

Compliance 

NWA requests that we revise the Cost 

of Compliance section of the NPRM to 

portray the cost to operators as though 

all four locations require a monument 

installation. NWA explains that 

airplanes configured with only a single 

lavatory require 57 labor hours for 

removal, installation, and testing. If an 

operator were to have a monument 

installation at each of the four locations, 

NWA asserts that the labor hours could 

be as high as 241 hours for an airplane 

configured with three lavatories and a 

video control center. 

We agree to revise the Cost of 

Compliance section of the final rule to 

portray the cost to operators as though 

all four locations require a monument 

installation. As the service information 

indicates, time to get access to the 

modified area should be included in the 

cost, with respect to operators having to 

perform a monument installation at all 

four locations. We are adding 3 workhours to NWA’s estimate of 241 workhours to account for the modification. 

Also, the number of affected products of 

U.S. registry is now 32. We have revised 

the Costs of Compliance section of the 

final rule accordingly. 

Conclusion 

We reviewed the available data, 

including the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously. 

We determined that these changes will 

not increase the economic burden on 

any operator or increase the scope of the 

AD. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 


cprice-sewell on DSK8KYBLC1PROD with RULES
Federal Register / Vol. 75, No. 98 / Friday, May 21, 2010 / Rules and Regulations 28477 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a NOTE within the AD. 

Explanation of Change to Costs of 

Compliance 

Since issuance of the NPRM, we have 

increased the labor rate used in the 

Costs of Compliance from $80 per workhour to $85 per work-hour. The Costs of 

Compliance information, below, reflects 

this increase in the specified hourly 

labor rate. 

Costs of Compliance 

We estimate that this AD will affect 

32 products of U.S. registry. We also 

estimate that it will take about 244 

work-hours per product to comply with 

the basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Required parts costs are negligible. 

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 $663,680, or $20,740 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 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); and 

3. 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, 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

section. Comments will be available in 

the AD docket shortly after receipt.

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2010–10–25 Airbus: Amendment 39–16304. 

Docket No. FAA–2009–0914; Directorate 

Identifier 2009–NM–122–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective June 25, 2010. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Airbus Model A330– 

201, –202, –203, –223, –243, –301, –302, 

–303, –321, –322, –323, –341, –342, and –343 

airplanes; and Airbus Model A340–311, 

–312, and –313 airplanes; certificated in any 

category; all manufacturer serial numbers on 

which Airbus Modification 48825 has been 

embodied in production, except those on 

which Airbus Modification 57409 has been 

embodied in production. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 92. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

In the door 2 area, the hat-racks are 

supplied with a basic wire harness which 

includes ‘‘Oxygen Masks’’ activation. 

In case of a monument installation, the 

respective non-used hat-rack connections 

between monument and outer skin are put on 

stow. It was noticed in production, that the 

distance between the stowed wire harness 

and the monument could be too small. This 

condition, if not corrected, could lead to the 

short circuit of wires dedicated to oxygen, 

which, in case of emergency, could result in 

a large number of passenger oxygen masks 

not being supplied with oxygen, possibly 

causing personal injuries. 

For the reasons described above, this AD 

requires the modification of the hat rack 

connectors on stow, and the rerouting of the 

associated wire harness in case of monument 

installed in door 2 area. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) For airplanes on which a monument is 

installed in the door 2 area, as specified in 

Airbus Mandatory Service Bulletin A330–92–

AS332L2 Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule; request for 

comments. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

specified ECF model helicopters. This 

AD results from a mandatory continuing 

airworthiness information (MCAI) AD 

issued by the European Aviation Safety 

Agency (EASA), which is the Technical 

Agent for the Member States of the 

European Community. The MCAI AD 

states that with certain pilot and copilot 

seats in the rear high position and seat 

backrest fully tilted the seat shoulder 

harness could become jammed between 

the seat and bulkhead. This condition, 

if not corrected, could result in the 

shoulder harness binding and causing 

the inertial reel to malfunction and no 

longer retain the flight crew member in 

the seat in the event of an emergency or 

hard landing. 

DATES: This AD becomes effective on 

June 7, 2010. 

The incorporation by reference of 

certain publications is approved by the 

Director of the Federal Register as of 

June 7, 2010. 

We must receive comments on this 

AD by July 20, 2010.
