Bulletin 777–27A0059, Revision 1, dated 

August 18, 2005; are considered acceptable 

for compliance with the corresponding 

actions specified in paragraphs (g), (h), and 

(i) of this AD. 

Credit for Hard-Time Replacement of HSTA 

(k) Any HSTA overhauled within the 

compliance times specified in paragraphs (g), 

(h), and (i) of this AD or before the effective 

date of this AD—as part of a ‘‘hard-time’’ 

replacement program that includes removal 

of the HSTA from the airplane and overhaul 

of the stabilizer ballscrew in accordance with 

original equipment manufacturer component 

maintenance manual instructions—meets the 

intent of one detailed inspection, one 

freeplay inspection, and one lubrication of 

the HSTA. Therefore, any such HSTA is 

considered acceptable for compliance with 

the initial accomplishment of the actions 

specified in paragraphs (g), (h), and (i) of this 

AD, and repetitions of those actions may be 

determined from the performance date of that 

overhaul. 

Parts Installation 

(l) As of the effective date of this AD, no 

person may install, on any airplane, a 

horizontal stabilizer trim actuator that is not 

in a ‘‘known serviceable condition’’ as 

defined in Note 6, section 3.A., of Boeing 

Alert Service Bulletin 777–27A0059, 

Revision 2, dated January 15, 2009; unless a 

detailed inspection, freeplay measurement, 

and lubrication of that actuator are performed 

in accordance with paragraphs (g), (h), and (i) 

of this AD, as applicable.

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: 

An internal review of design data has 

shown that the web of the left hand side (LH) 

stringer 13 near frame 8 might have been 

improperly trimmed on a few aircraft. 

If not corrected, possible crack initiations 

could occur in the upper stringer web, and 

therefore could impair the structural strength 

of the adjacent door stop. This latent failure 

could ultimately lead to the loss of 

redundancy of the door stops, thereby 

affecting the structural integrity of the 

fuselage. 

* * * * * * * 

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 April 27, 2009 (74 FR 

19027). That NPRM proposed to correct 

an unsafe condition for the specified 

products. The MCAI states: 

An internal review of design data has 

shown that the web of the left hand side (LH) 

stringer 13 near frame 8 might have been 

improperly trimmed on a few aircraft. 

If not corrected, possible crack initiations 

could occur in the upper stringer web, and 

therefore could impair the structural strength 

of the adjacent door stop. This latent failure 

could ultimately lead to the loss of 

redundancy of the door stops, thereby 

affecting the structural integrity of the 

fuselage. 

Computational analysis has revealed a 

substantial reduced fatigue life for the 

stringer abutting onto the improperly 

trimmed web and has determined the need 

for an inspection and repair action no later 

than the first ‘‘C’’ check. 

To address this unsafe condition, the 

present Airworthiness Directive (AD) 

mandates an inspection and a conditional 

rework or replacement of the web of the LH 

stringer 13 between frames 7 and 8. 

Required actions include measuring the 

trimmed length of the web, inspecting 

for any sharp and unprotected edges of 

the web, and doing corrective actions if 

necessary. Corrective actions include 

reworking the web and applying 

protection to the web, or replacing the 

web, if improperly trimmed. 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 or 


sroberts on DSKD5P82C1PROD with RULES
32418 Federal Register / Vol. 74, No. 129 / Wednesday, July 8, 2009 / Rules and Regulations 

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. 

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 

12 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 $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.

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: 

2009–14–09 Dassault Aviation: 

Amendment 39–15959. Docket No. 

FAA–2009–0380; Directorate Identifier 

2008–NM–153–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective August 12, 2009. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Dassault Model 

Falcon 2000EX airplanes, certificated in any 

category, serial numbers 102 through 124 

inclusive. 

Subject 

(d) Air Transport Association (ATA) of 

America Code 53: Fuselage. 

Reason 

(e) The mandatory continuing 

airworthiness information (MCAI) states: 

An internal review of design data has 

shown that the web of the left hand side (LH) 

stringer 13 near frame 8 might have been 

improperly trimmed on a few aircraft. 

If not corrected, possible crack initiations 

could occur in the upper stringer web, and 

therefore could impair the structural strength 

of the adjacent door stop. This latent failure 

could ultimately lead to the loss of 

redundancy of the door stops, thereby 

affecting the structural integrity of the 

fuselage. 

Computational analysis has revealed a 

substantial reduced fatigue life for the 

stringer abutting onto the improperly 

trimmed web and has determined the need 

for an inspection and repair action no later 

than the first ‘‘C’’ check. 

To address this unsafe condition, the 

present Airworthiness Directive (AD) 

mandates an inspection and a conditional 

rework or replacement of the web of the LH 

stringer 13 between frames 7 and 8. 

Required actions include measuring the 

trimmed length of the web, inspecting for any 

sharp and unprotected edges of the web, and 

doing corrective actions if necessary. 

Corrective actions include reworking the web 

and applying protection to the web, or 

replacing the web, if improperly trimmed. 

Actions and Compliance 

(f) Unless already done, do the following 

actions. 

(1) At the later of the times in paragraphs 

(f)(1)(i) and (f)(1)(ii) of this AD: Perform a 

detailed visual inspection to detect any sharp

stringer 13 between frames 7 and 8, and 

measure the trimmed length of the web, in 

accordance with the Accomplishment 

Instructions of Dassault Mandatory Service 

Bulletin F2000EX–178, dated July 1, 2008. 

(i) Before the accumulation of 3,750 total 

flight cycles, or within 74 months since the 

date of issuance of the original French 

airworthiness certificate or the date of 

issuance of the original French export 

certificate of airworthiness, whichever occurs 

first. 

(ii) Within 6 months after the effective date 

of this AD. 

(2) If, during the inspection and 

measurement required by paragraph (f)(1) of 

this AD, any sharp or unprotected edge is 

found, or if the trimmed length is 1.57 inches 

(40 mm) or greater, before further flight, do 

all applicable corrective actions, in 

accordance with the Accomplishment 

Instructions of Dassault Mandatory Service 

Bulletin F2000EX–178, dated July 1, 2008.

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
