14 CFR Part 39 

[Docket No. FAA–2010–1311; Directorate 

Identifier 2009–NM–229–AD; Amendment 

39–16938; AD 2012–02–15] 

RIN 2120–AA64 

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are superseding an 

existing airworthiness directive (AD) for 

certain Model 757–200, –200PF, 

–200CB, and –300 series airplanes. That 

AD currently requires inspecting certain 

power feeder wire bundles for damage, 

inspecting the support clamps for these 

wire bundles to determine whether the 

clamps are properly installed, and 

performing corrective actions if 

necessary. This new AD requires 

additional inspections for certain 

airplanes. This AD was prompted by a 

report that a power feeder wire bundle 

chafed against the number six auxiliary 

slat track, causing electrical wires in the 

bundle to arc, which damaged both the 

auxiliary slat track and power feeder 

wires. We are issuing this AD to prevent 

arcing that could be a possible ignition 

source for leaked flammable fluids, 

which could result in a fire. Arcing 

could also result in a loss of power from 

the generator connected to the power 

feeder wire bundle, and consequent loss 

of systems, which could reduce 

controllability of the airplane. 

DATES: This AD is effective April 4, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in the AD 

as of April 4, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2007–03–01, 

amendment 39–14912 (72 FR 3939, 

January 29, 2007). That AD applies to 

the specified products. The NPRM was 

published in the Federal Register on 

January 18, 2011 (76 FR 2848). That 

NPRM proposed to continue to require 

inspecting certain power feeder wire 

bundles for damage, inspecting the 

support clamps for those wire bundles 

to determine whether the clamps are 

properly installed, and performing 

corrective actions if necessary. That 

NPRM also proposed to require 

additional inspections for certain 

airplanes. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Requests To Correct Figure Reference 

in Paragraph (i) of the NPRM (76 FR 

2848, January 18, 2011) 

United Airlines and American 

Airlines requested that paragraph (i) of 

the NPRM (76 FR 2848, January 18, 

2011) be changed to reference Figure 1 

rather than Figure 3 of Boeing Special 

Attention Service Bulletin 757–24– 

0105, Revision 5, dated July 30, 2009. 

Boeing Special Attention Service 

Bulletin 757–24–0105, Revision 5, dated 

July 30, 2009, has a typographical error 

referencing the incorrect figure. United 

Airlines also requested that the NPRM 

refer to Boeing Information Notice 757– 

24–0105 IN 03, dated August 19, 2009. 

United Airlines stated that Boeing 

Information Notice 757–24–0105 IN 03, 

dated August 19, 2009, was issued to 

notify operators of this error. 

We agree to revise paragraph (i) of this 

AD to refer to Figure 1 of Boeing Special 

Attention Service Bulletin 757–24– 

0105, Revision 5, dated July 30, 2009. 

We have confirmed that the correct 

figure is Figure 1; therefore, we have 

revised paragraph (i) of this AD to refer 

to Figure 1 of Boeing Special Attention 

Service Bulletin 757–24–0105, Revision 

5, dated July 30, 2009. We have not 

revised paragraph (i) of this AD to refer 

to Boeing Information Notice 757–24– 

0105 IN 03, dated August 19, 2009, 

because we revised that paragraph to 

refer to the correct figure. 

Request To Add Inspection To 

Determine Airplane Configuration 

American Airlines requested that the 

NPRM (76 FR 2848, January 18, 2011) be 

revised to include an inspection to 

determine if the airplane has one or two 

attach brackets on the left wing prior to 

accomplishing the required rework. 

American Airlines stated that Group 2 

airplanes were moved to Group 1 in 

Boeing Special Attention Service 

Bulletin 757–24–0105, Revision 5, dated 

July 30, 2009, because some airplanes 

have two attach brackets on the left 

wing, similar to earlier Group 1 

airplanes identified in previous 

revisions of that service bulletin. 

American Airlines stated that the NPRM 

does not contain a step to determine the 

airplane configuration before the 

rework. 

We disagree with adding an 

inspection to determine the airplane 

configuration; however, we agree to 

clarify paragraph (i) of this AD. 

Therefore, we have revised paragraph (i) 

of this AD to specify the affected 

airplanes on which the actions are 

required by that paragraph. 

Request To Clarify Affected Airplanes 

in Paragraph (i) of the NPRM (76 FR 

2848, January 18, 2011) 

United Airlines requested that a 

statement be added to clarify that the 

new requirement specified in paragraph 

(i) of the NPRM (76 FR 2848, January 18, 

2011) is only applicable to airplanes 

with upper and lower brackets installed 

in the left wing (Group 1, Configuration 

1 airplanes), as defined in Boeing 

Special Attention Service Bulletin 757– 

24–0105, Revision 5, dated July 30, 

2009. United Airlines stated that the 

NPRM is unclear regarding which 


tkelley on DSK3SPTVN1PROD with RULES
Federal Register / Vol. 77, No. 40 / Wednesday, February 29, 2012 / Rules and Regulations 12167 

airplanes are affected by the new 

requirements. 

We agree that clarification is needed. 

Airplanes in Group 1, as specified in 

Boeing Special Attention Service 

Bulletin 757–24–0105, Revision 5, dated 

July 30, 2009, could be in the 

configuration shown in Figure 1 

(Configuration 1 with two attach 

brackets on the left wing) or Figure 3 

(Configuration 2 with one attach bracket 

on the left wing). Therefore, as stated 

previously, we have clarified paragraph 

(i) of this AD to specify the affected 

airplanes. 

Request To Provide Credit for Previous 

Work Done Using Boeing Special 

Attention Service Bulletin 757–24–0105, 

Revision 5, Dated July 30, 2009 

European Air Transport, a company of 

DHL, requested that we revise the 

NPRM (76 FR 2848, January 18, 2011) to 

provide credit to operators that have 

accomplished inspections and 

corrective actions prior to the effective 

date of this AD in accordance with 

Boeing Special Attention Service 

Bulletin 757–24–0105, Revision 5, dated 

July 30, 2009. European Air Transport 

pointed out that the NPRM provides 

credit for actions accomplished using 

previous revisions of Boeing Special 

Attention Service Bulletin 757–24– 

0106, which is applicable to Model 757– 

300 airplanes. 

We agree that inspections and 

corrective actions done before the 

effective date of this AD in accordance 

with Boeing Special Attention Service 

Bulletin 757–24–0105, Revision 5, dated 

July 30, 2009, are acceptable for 

accomplishing the applicable actions 

specified in this AD. However, operators 

may always accomplish the actions in 

an AD using the required service 

information at any time before the 

effective date of the AD, as allowed by 

the phrase ‘‘unless the actions have 

already been done.’’ Therefore, because 

these actions are not required to be 

repeated, it is unnecessary to provide 

specific credit for these actions. We 

have made no change to the AD in this 

regard. 

Additional Changes to Final Rule 

We have revised the headings of 

Tables 1, 2, 3, 4, and 5 of this AD to 

clarify the purpose of the content in 

those tables. 

We have included headings for 

paragraphs (i) and (j) of this AD to 

clarify the purpose of the content in 

those paragraphs. 

Boeing Special Attention Service 

Bulletin 757–24–0105, Revision 3, dated 

October 3, 2006; and Revision 4, dated 

January 4, 2008; have been added to 

Table 5, ‘‘Previous Service Information 

for Paragraph (g) of this AD,’’ of this AD. 

We have also revised the headings for 

and wording in paragraphs (h) and (k) 

of this AD; these changes have not 

changed the intent of these paragraphs. 

Conclusion 

We reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting the AD 

with the changes described previously 

and minor editorial changes. We have 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM (76 FR 2848, 

January 18, 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 2848, 

January 18, 2011). 

We also determined that these 

changes will not increase the economic 

burden on any operator or increase the 

scope of the AD. 

Costs of Compliance 

We estimate that this AD affects 683 

airplanes of U.S. registry. 

We estimate the following costs to 

comply with this AD: 

ESTIMATED COSTS

specified in 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 have 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 that this AD: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 


tkelley on DSK3SPTVN1PROD with RULES
12168 Federal Register / Vol. 77, No. 40 / Wednesday, February 29, 2012 / Rules and Regulations 

(2) Is not a ‘‘significant rule’’ under 

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. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

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 

removing airworthiness directive (AD) 

2007–03–01, Amendment 39–14912 (72 

FR 3939, January 29, 2007), and adding 

the following new AD: 

2012–02–15 The Boeing Company: 

Amendment 39–16938; Docket No. 

FAA–2010–1311; Directorate Identifier 

2009–NM–229–AD. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective April 4, 2012. 

(b) Affected ADs 

This AD supersedes AD 2007–03–01, 

Amendment 39–14912 (72 FR 3939, January 

29, 2007). 

(c) Applicability 

This AD applies to The Boeing Company 

Model 757–200, –200PF, –200CB, and –300 

series airplanes, certificated in any category, 

specified in paragraphs (c)(1) and (c)(2) of 

this AD. 

(1) Model 757–200, –200PF, and –200CB 

series airplanes, as identified in Boeing 

Special Attention Service Bulletin 757–24– 

0105, Revision 5, dated July 30, 2009. 

(2) Model 757–300 series airplanes, as 

identified in Boeing Special Attention 

Service Bulletin 757–24–0106, Revision 5, 

dated July 30, 2009. 

(d) Subject 

Air Transport Association (ATA) of 

America Code 24: Electrical power. 

(e) Unsafe Condition 

This AD results from a report that a power 

feeder wire bundle chafed against the 

number six auxiliary slat track, causing 

electrical wires in the bundle to arc, which 

damaged both the auxiliary slat track and 

power feeder wires. The Federal Aviation 

Administration is issuing this AD to prevent 

arcing that could be a possible ignition 

source for leaked flammable fluids, which 

could result in a fire. Arcing could also result 

in a loss of power from the generator 

connected to the power feeder wire bundle, 

and consequent loss of systems, which could 

reduce controllability of the airplane. 

(f) Compliance 

You are responsible for having the actions 

required by this AD performed within the 

compliance times specified, unless the 

actions have already been done. 

(g) Restatement of Requirements of AD 2007– 

03–01, Amendment 39–14912 (72 FR 3939,

Airworthiness Directives; The Boeing 

Company Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for all 

Model 757 airplanes. This AD was 

prompted reports that several operators 

have found cracking in the front spar 

lower chord at the fastener locations 

common to the side link support fitting 

at wing station (WS) 292. This AD 

requires repetitive inspections for 

corrosion and cracking in this area, and 

corrective actions if necessary. We are 

issuing this AD to detect and correct 

such corrosion and cracking, which, if 

not corrected, could grow and result in 

structural failure of the spar. 

DATES: This AD is effective April 4, 

2012. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in the AD 

as of April 4, 2012.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an airworthiness 

directive (AD) that would apply to the 

specified products. That NPRM 

published in the Federal Register on 

January 22, 2010 (75 FR 3660). That 

NPRM proposed to require repetitive 

inspections for corrosion and cracking 

in the front spar lower chord at the 

fastener locations common to the side 

link support fitting at wing station (WS) 

292, and corrective actions if necessary. 

Actions Since Issuance of NPRM (75 FR 

3660, January 22, 2010) 

The NPRM (75 FR 3660, January 22, 

2010) referred to Boeing Special 

Attention Service Bulletin 757–57– 

0065, dated May 14, 2009, as the 

appropriate source of service 

information for accomplishing the 

actions. Since issuance of the NPRM, 

Boeing has issued Special Attention 

Service Bulletin 757–57–0065, Revision 

1, dated August 1, 2011. No more work 

is necessary for airplanes on which the 

original issue was used to accomplish 

the actions. Certain procedures 

specified in Revision 1 of this service 

bulletin have been clarified to provide 

additional instructions. 

We have revised this AD to refer to 

Boeing Special Attention Service 

Bulletin 757–57–0065, Revision 1, dated 

August 1, 2011, as the appropriate 

source of service information for 

accomplishing the actions. In addition, 

we added a new paragraph (i) to this AD 

(and reidentified subsequent paragraphs 

accordingly) to give credit for using 

Boeing Special Attention Service 

Bulletin 757–57–0065, dated May 14, 

2009, for accomplishing the actions. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. The 

following presents the comments 

received on the proposal and the FAA’s 

response to each comment. 

Supportive Comment 

Boeing concurred with the content of 

the NPRM (75 FR 3660, January 22, 

2010). 

Request To Include Instructions for 

Airplanes With Unmodified 

Configurations at the Side Link Fitting 

FedEx stated that Figures 2 and 3 of 

the Boeing Special Attention Service 

Bulletin 757–57–0065, dated May 14, 

2009, show a configuration of the 

airplane with the modification of the 

side link fitting accomplished. FedEx 

added that the procedures in that 

service information replace the side link
