(d) Subject 

Joint Aircraft System Component (JASC)/ 

Air Transport Association (ATA) of America 

Code 2560, Emergency Equipment. 

(e) Unsafe Condition 

This AD was prompted by reports that 

during workshop testing, certain pressure 

relief valves did not seal and allowed the 

pressure in certain slides/rafts to fall below 

the minimum raft mode pressure for the unit. 

We are issuing this AD to prevent loss of 

pressure in the escape slides/rafts after an 

emergency evacuation, which could result in 

inadequate buoyancy to support the raft’s 

passenger capacity during ditching and 

increase the chance for injury to raft 

passengers. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Inspection 

Within 36 months after the effective date 

of this AD, inspect the evacuation systems to 

determine whether any pressure relief valve 

having part number (P/N) 4A3641–1, 

4A3791–3, 4A3641–26, or 4A3791–6 is 

installed. A review of airplane maintenance 

records or the system identification placard 

on the girt is acceptable in lieu of this 

inspection if the part number of the pressure 

relief valve can be conclusively determined 

from that review. 

(h) Part Replacement 

If any valve having P/N 4A3641–1, 

4A3791–3, 4A3641–26, or 4A3791–6 is 

identified during the inspection or review 

specified in paragraph (g) of this AD: Before 

further flight, do the applicable actions 

required by paragraphs (h)(1) and (h)(2) of 

this AD: 

(1) Replace all pressure relief valves having 

P/Ns 4A3641–1 and 4A3791–3 with pressure 

relief valves having P/N 115815–1, and mark 

the system identification placard on the girt, 

in accordance with the Accomplishment 

Instructions of Goodrich Service Bulletin 

7A1508/09/10/39–25–373, Revision 3, dated 

March 30, 2011. 

(2) Replace all pressure relief valves having 

P/Ns 4A3641–26 and 4A3791–6 with 

pressure relief valves having P/N 115815–1 

(for evacuation systems having P/N 4A3934 

series units) or 115815–2 (for evacuation 

systems having P/N 4A3928 series units); and 

mark the system identification placard on the 

girt; in accordance with the Accomplishment 

Instructions of Goodrich Service Bulletin 

4A3928/4A3934–25–374, Revision 2, dated 

March 30, 2011. 

(i) Parts Installation 

As of the effective date of this AD, no 

person may install a pressure relief valve 

having P/N 4A3641–1, 4A3791–3, 4A3641– 

26, or 4A3791–6 in the evacuation system on 

any airplane. 

(j) Credit for Previous Actions 

This paragraph provides credit for actions 

required by paragraphs (g) and (h) of this AD,

SUMMARY: We are adopting a new 

airworthiness directive (AD) for certain 

Airbus Model A330–200, A330–300, 

A340–500, and A340–600 series 

airplanes. This AD requires a detailed 

inspection for cracked and missing nuts, 

and replacement of cracked or missing 

nuts with new nuts having the same 

part number. This AD was prompted by 

reports of cracked nuts detected during 

production. We are issuing this AD to 

detect and correct cracked or missing 

nuts, and replace all affected nuts in 

multiple locations (including fuel tank 

areas) that could result in reduced 

structural integrity of the airplane. 

DATES: This AD becomes effective April 

16, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of April 16, 2012. 

We must receive comments on this 

AD by May 14, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

The European Aviation Safety Agency 

(EASA), which is the Technical Agent 

for the Member States of the European 

Community, has issued EASA 

Airworthiness Directive 2010–0252, 

dated November 29, 2010 (referred to 

after this as ‘‘the MCAI’’), to correct an 

unsafe condition for the specified 

products. The MCAI states: 

During structural part assembly in Airbus 

production line, some nuts Part Number (P/ 

N) ASNA2531–4 were found cracked. 

Investigations were performed to 

determine batches of the affected nuts. 

Static, fatigue and corrosion tests were 

performed and demonstrated that no 

immediate maintenance action is necessary. 

However, due to the large number of these 

nuts fitted on primary structural elements, 

this condition, if not corrected, could impair 

the structural integrity of the affected 

aeroplanes. 

This [EASA] AD requires detailed 

inspection [for cracked and missing nuts] and 

replacement of nuts P/N ASNA2531–4 with 

new ones having the same P/N, in order to 

restore the structural integrity of the affected 

aeroplanes, and the accomplishment of the 

applicable corrective actions. [If no missing 

or cracked nut is found, replace with new 

nut.] 

You may obtain further information by 

examining the MCAI in the AD docket. 

Relevant Service Information 

Airbus has issued Mandatory Service 

Bulletin A330–53–3183, including 

Appendices 01 and 02, dated September 

30, 2010 (for Model A330–200 and –300 

series airplanes); and Mandatory Service 

Bulletin A340–53–5056, including 

Appendices 01 and 02, dated October 7, 

2010 (for Model A340–500 and –600 

series airplanes). The actions described 

in this service information are intended 

to correct the unsafe condition 

identified in the MCAI. 

FAA’s Determination and Requirements 

of This 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 the State of 

Design Authority, we have been notified 

of the unsafe condition described in the 

MCAI and service information 

referenced above. We are issuing this 

AD because we evaluated all pertinent 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

There are no products of this type 

currently registered in the United States. 

However, this rule is necessary to 

ensure that the described unsafe 

condition is addressed if any of these 

products are placed on the U.S. Register 

in the future. 

Differences Between the AD and the 

MCAI or Service Information 

This AD differs from the MCAI and/ 

or service information as follows: The 

MCAI and the service information 

include a reporting requirement. This 

AD does not require reporting of the 

inspection results to the airplane 

manufacturer. 

FAA’s Determination of the Effective 

Date 

Since there are currently no domestic 

operators of this product, notice and 

opportunity for public comment before 

issuing this AD are unnecessary. 

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–2012–0292; 

Directorate Identifier 2011–NM–056– 

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. 

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); 

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.

Airworthiness Directives; DASSAULT 

AVIATION Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

DASSAULT AVIATION Model 

MYSTERE-FALCON 900 airplanes. This 

AD was prompted by multiple reports of 

fuel leakage from a defective fuel highlevel sensor located in the wing front 

spar. This AD requires inspecting to 

determine fuel quantity sensors part 

numbers and replacing of certain fuel 

quantity sensors with new fuel quantity 

sensors. We are issuing this AD to 

prevent internal fuel leakage with 

significant fuel vapors, which could 

result in a fire hazard. 

DATES: This AD becomes effective May 

4, 2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of May 4, 2012. 

ADDRESSES: You may examine the AD 

docket on the Internet at http://

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 November 4, 2011 (76 FR 

68368). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

Several Mystere-Falcon 900 aeroplanes 

experienced fuel leakage from a defective 

fuel high-level sensor located in the wing 

front spar. 

Investigations revealed that the leakage 

was due to a defective fuel quantity sensor 

Part Number (P/N) 722105–2. 

This condition, if not detected and 

corrected, could lead to an internal fuel 

leakage with significant fuel vapours, which 

could result in a fire hazard. 

To address this unsafe condition, Dassault 

Aviation have developed an improved fuel 

quantity sensor with a new concept of 

sealing. 

For the reasons described above, this 

[EASA] AD requires the identification of the 

affected sensors and replacement with the 

improved part. 

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 NPRM (76 

FR 68368, November 4, 2011) 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 NPRM (76 FR 

68368, November 4, 2011) for correcting 

the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM (76 FR 68368, 

November 4, 2011). 

Costs of Compliance 

We estimate that this AD will affect 

110 products of U.S. registry. We also 

estimate that it will take about 4 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 $4,000 

per product. Where the service
