AGENCY: Federal Aviation 

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: 

This Airworthiness Directive (AD) is 

issued following the discovery of hot air 

leaks when operating the wing anti-icing 

system. The seals Part Number (P/N) 

MS29513–325, near the de-icing valves 

(12H1) and (12H2) in frame 33 area, do not 

have the proper temperature rating. 

The consequences, in the area of the hot air 

leak, are risks of ignition of potential 

hydraulic leaks. 

* * * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

August 12, 2009. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of August 12, 2009.

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 March 26, 2009 (74 FR 

13147). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

This Airworthiness Directive (AD) is 

issued following the discovery of hot air 

leaks when operating the wing anti-icing 

system. The seals Part Number (P/N) 

MS29513–325, near the de-icing valves 

(12H1) and (12H2) in frame 33 area, do not 

have the proper temperature rating. 

The consequences, in the area of the hot air 

leak, are risks of ignition of potential 

hydraulic leaks. 

The purpose of this AD is to verify that 

seals with correct temperature rating have 

been installed on Mystere-Falcon 20-()5 

airplanes. 

The corrective action includes replacing 

the left and right seals near de-icing 

valves (12H1) and (12H2) in frame area 

33. 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 To Refer to Current Revision of 

the Service Bulletin 

Dassault Falcon Jet Corporation 

(Dassault) requests that we revise the 

NPRM to refer to Revision 1 of Dassault 

Mandatory Service Bulletin F20–766, 

dated June 24, 2008, in this AD. We 

referred to Dassault Service Bulletin 

F20–766, dated October 31, 2005, in the 

NPRM as the appropriate source of 

service information for doing the 

proposed requirements. 

We agree. Dassault Mandatory Service 

Bulletin F20–766, Revision 1, dated 

June 24, 2008, does not specify any 

additional action for airplanes on which 

the required actions have been 

accomplished in accordance with the 

original issue of Dassault Service 

Bulletin F20–766, dated October 31, 

2005. Also, paragraph 1.D. of Dassault 

Mandatory Service Bulletin F20–766, 


sroberts on DSKD5P82C1PROD with RULES
32420 Federal Register / Vol. 74, No. 129 / Wednesday, July 8, 2009 / Rules and Regulations 

Revision 1, dated June 24, 2008, revises 

the compliance to correspond with the 

MCAI. Therefore, we revised paragraphs 

(f) and (h) of this AD to refer to Dassault 

Mandatory Service Bulletin F20–766, 

Revision 1, dated June 24, 2008. We 

have also revised paragraph (f) of this 

AD to give credit for actions done before 

the effective date of this AD in 

accordance with Dassault Service 

Bulletin F20–766, dated October 31, 

2005. 

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 

187 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 $80 per work-hour. 

Based on these figures, we estimate the 

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

be $14,960, or $80 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.

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Mystere-Falcon 20– 

C5, 20–D5, 20–E5, and 20–F5 airplanes, 

certificated in any category, without Dassault 

Service Bulletin F20–766 implemented. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 30: Ice and rain protection. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

This Airworthiness Directive (AD) is 

issued following the discovery of hot air 

leaks when operating the wing anti-icing 

system. The seals Part Number (P/N) 

MS29513–325, near the de-icing valves 

(12H1) and (12H2) in frame 33 area, do not 

have the proper temperature rating. 

The consequences, in the area of the hot air 

leak, are risks of ignition of potential 

hydraulic leaks. 

The purpose of this AD is to verify that 

seals with correct temperature rating have 

been installed on Mystere-Falcon 20–()5 

airplanes. 

The corrective action includes replacing the 

left and right seals near de-icing valves 

(12H1) and (12H2) in frame area 33. 

Actions and Compliance 

(f) Unless already done, within 7 months 

after the effective date of this AD, perform an 

inspection for a red line marking on each of 

the Wiggins couplings that are located near 

the de-icing valves (12H1) and (12H2), in 

accordance with Dassault Mandatory Service 

Bulletin F20–766, Revision 1, dated June 24, 

2008. If a red line is not found, prior to 

further flight, replace the seals to the left and 

right Wiggins couplings, in accordance with 

Dassault Mandatory Service Bulletin F20– 

766, Revision 1, dated June 24, 2008. 

Inspections and replacements accomplished 

before the effective date of this AD in 

accordance with Dassault Service Bulletin 

F20–766, dated October 31, 2005, are 

considered acceptable for compliance with 

the corresponding actions specified in this 

AD.

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for Pratt & 

Whitney models PW2037, PW2037(M), 

and PW2040 turbofan engines. This AD 

requires 12th stage disks of certain highpressure compressor (HPC) drum rotor 

disk assemblies, to be inspected for 

cracks by Pratt & Whitney using a 

special eddy current inspection 

procedure. This AD results from six 

HPC 12th stage disks found cracked 

during HPC module disassembly at 

overhaul. We are issuing this AD to 

prevent uncontained failure of the HPC 

12th stage disk and airplane damage. 

DATES: This AD becomes effective July 

23, 2009. The Director of the Federal 

Register approved the incorporation by 

reference of certain publications listed 

in the regulations as of July 23, 2009. 

We must receive any comments on 

this AD by September 8, 2009.

SUPPLEMENTARY INFORMATION: In 

November 2006, a Pratt & Whitney 

model PW2037 turbofan engine was 

found to have a cracked HPC 12th stage 

disk during routine overhaul. The crack 

extended from the disk bore to the disk 

rim. Investigation by Pratt & Whitney 

revealed that the disk had a material 

defect that occurred during original 

manufacture. In July 2007, a second 

HPC 12th stage disk was found cracked 

with the same defect. In response to the 

cracking, Pratt & Whitney issued Alert 

Service Bulletin (ASB) No. PW2000 

A72–736 on January 5, 2009, 

recommending removal of 26 additional 

HPC 12th stage disks, manufactured 

from this same material heat. Pratt 

concluded that this population might 

have the same material defects and 

therefore, be susceptible to cracking. 

Thereafter, in February 2009, after Pratt 

& Whitney issued the ASB, we became 

aware of four additional HPC 12th stage 

disks, manufactured from the same 

material heat, that had small cracks in 

the disk bores that originated from 

similar material defects. Because of Pratt 

& Whitney’s recommended short 

compliance times in the ASB, we are 

issuing this final rule; request for 

comments AD. This condition, if not 

corrected, could result in uncontained 

failure of the HPC 12th stage disk and 

airplane damage. 

Relevant Service Information 

We have reviewed and approved the 

technical contents of Pratt & Whitney 

ASB No. PW2000 A72–736, dated 

January 5, 2009. That ASB describes 

procedures for having Pratt & Whitney 

perform the special eddy-current 

inspection performed on the 12th stage 

disks. 

Differences Between This AD and the 

Service Information 

The recommended compliance times 

in the Pratt & Whitney ASB are stated 

as calendar dates for each engine model. 

We specify cycles-in-service rather than 

calendar dates, because the risk of crack 

development is cycle, not time 

dependant.
