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: 

During maintenance on one aircraft, it was 

discovered that the overpressure capsules 

were broken on both pressurization valves. 

Failure of the pressurization control 

regulating valve (overpressure capsule) will 

affect the aircraft’s overpressure protection 

* * *. 

* * * * * 

The unsafe condition is 

overpressurization, which can result in 

injury to the occupants and possible 

structural failure leading to loss of 

control of the airplane. We are issuing 

this AD to require actions to correct the 

unsafe condition on these products. 

DATES: This AD becomes effective 

January 25, 2011.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a supplemental notice of 

proposed rulemaking (NPRM) to amend 

14 CFR part 39 to include an AD that 

would apply to the specified products. 

That supplemental NPRM was 

published in the Federal Register on 

July 27, 2010 (75 FR 43878). That 

supplemental NPRM proposed to 

correct an unsafe condition for the 

specified products. The MCAI states: 

During maintenance on one aircraft, it was 

discovered that the overpressure capsules 

were broken on both pressurization valves. 

Failure of the pressurization control 

regulating valve (overpressure capsule) will 

affect the aircraft’s overpressure protection, 

possibly resulting in a structural failure in 

case of combination with another 

pressurization system failure. Consequently, 

Dassault Aviation has developed a repetitive 

check of this outflow valve capsule, which 

has already been introduced into the 

Maintenance of Components section (chapter 

5–20) of the relevant Aircraft Maintenance 

Manuals (AMMs). 

For the reason described above, this EASA 

[European Aviation Safety Agency] 

Airworthiness Directive (AD) requires a 

repetitive check of the outflow valve 

overpressure capsule, as it will also be 

introduced into the Airworthiness 

Limitations section (chapter 5–40) of the 

respective AMMs. 

The unsafe condition is 

overpressurization, which can result in 

injury to the occupants and possible 

structural failure leading to loss of 

control of the airplane. Required actions 

include repetitive inspections for 

overpressure tightness on both 

regulating valves, and replacing the 

affected valve with a serviceable unit if 

necessary. 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 Certain Airplanes To Be 

Included in the Time Extension 

Dassault Aviation requested that we 

revise the supplemental NPRM to 

extend the time interval for Model 

Mystere-Falcon 50 airplanes, for the 

overpressure tightness check that was 

specified in the supplemental NPRM. 

The extension of the time interval 

specified in the supplemental NPRM 

was from 1,630 flight hours to 1,640 

flight hours for other models. 

We agree to extend the time interval 

for Model Mystere-Falcon 50 airplanes 


jlentini on DSKJ8SOYB1PROD with RULES
Federal Register / Vol. 75, No. 244 / Tuesday, December 21, 2010 / Rules and Regulations 79953 

in the final rule. The original NPRM 

defined a time interval for Model 

MYSTERE-FALCON 50, MYSTEREFALCON 900, FALCON 900EX, 

FALCON 2000, and FALCON 2000EX 

airplanes. The supplemental NPRM 

extended the time interval for Model 

MYSTERE-FALCON 900, FALCON 

900EX, FALCON 2000, and FALCON 

2000EX airplanes. The extended 

interval for Model MYSTERE-FALCON 

50 airplanes from 1,630 flight hours to 

1,640 flight hours was coordinated with 

EASA. We have revised Table 1 of 

paragraph (g)(1) of the final rule 

accordingly. 

Request for Inclusion of the Latest 

Procedure 

Dassault Aviation requested that we 

revise the supplemental NPRM to refer 

to the most current version of Dassault 

Maintenance Procedure 21–160, of the 

Dassault Falcon 50/50EX Maintenance 

Manual. Dassault Aviation explains that 

the referenced maintenance procedure 

has been updated with a new picture 

and that the procedure is now dated 

January 2010. 

We agree for the reasons stated by the 

commenter. We have revised Table 2 of 

the final rule to refer to Dassault 

Maintenance Procedure 21–160, dated 

January 2010, as a source of guidance on 

inspecting for overpress tightness on 

both valves for Model MYSTEREFALCON 50 airplanes. 

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. 

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 

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. 

Costs of Compliance 

We estimate that this AD will affect 

1,082 products of U.S. registry. We also 

estimate that it will take about 1 workhour per product to comply with the 

basic requirements of this AD. The 

average labor rate is $85 per work-hour. 

Based on these figures, we estimate the 

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

be $91,970, or $85 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.
