We are superseding Airworthiness Directive (AD) 2003-13-01 for certain The Boeing Company Model 767 airplanes. AD 2003-13-01 required an inspection to detect cracks and fractures of the outboard hinge fitting assemblies on the trailing edge of the inboard main flap, and follow-on and corrective actions if necessary. For certain airplanes, AD 2003-13-01 required an inspection to determine if a tool runout option has been performed in the area. This new AD reduces certain compliance times, adds airplanes to the applicability, and provides optional terminating action for certain inspections. This AD was prompted by reports of hinge assembly fractures found before certain required compliance times in AD 2003-13-01. We are issuing this AD to prevent the inboard aft flap from separating from the wing and potentially striking the airplane, which could result in damage to the surrounding structure and potential personal injury.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are superseding Airworthiness Directive (AD) 2003-13-01 for 
certain The Boeing Company Model 767 airplanes. AD 2003-13-01 required 
an inspection to detect cracks and fractures of the outboard hinge 
fitting assemblies on the trailing edge of the inboard main flap, and 
follow-on and corrective actions if necessary. For certain airplanes, 
AD 2003-13-01 required an inspection to determine if a tool runout 
option has been performed in the area. This new AD reduces certain 
compliance times, adds airplanes to the applicability, and provides 
optional terminating action for certain inspections. This AD was 
prompted by reports of hinge assembly fractures found before certain 
required compliance times in AD 2003-13-01. We are issuing this AD to 
prevent the inboard aft flap from separating from the wing and 
potentially striking the airplane, which could result in damage to the 
surrounding structure and potential personal injury.

DATES: This AD is effective November 13, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of November 13, 
2015.
    The Director of the Federal Register approved the incorporation by

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to supersede AD 2003-13-01, Amendment 39-13201 (68 
FR 37402, June 24, 2003). AD 2003-13-01 applied to certain The Boeing 
Company Model 767 airplanes. The SNPRM published in the Federal 
Register on September 29, 2014 (79 FR 58294). We preceded the SNPRM 
with a notice of proposed rulemaking (NPRM) that published in the 
Federal Register on February 9, 2012 (77 FR 6685). The NPRM proposed to 
continue to require an inspection to detect cracks and fractures of the 
outboard hinge fitting assemblies on the trailing edge of the inboard 
main flap, and follow-on and corrective actions if necessary. For 
certain airplanes, the NPRM proposed to continue to require inspecting 
to determine if a tool runout option has been performed in the area. 
The NPRM also proposed to reduce a certain compliance time and add 
airplanes to the applicability. The NPRM provided optional terminating 
action for certain inspections. The NPRM was prompted by reports of 
hinge assembly fractures found before certain required compliance times 
in AD 2003-13-01. The SNPRM revised the NPRM by reducing repetitive 
inspection intervals for certain airplanes and limiting the inspection 
area. We are issuing this AD to prevent the inboard aft flap from 
separating from the wing and potentially striking the airplane, which 
could result in damage to the surrounding structure and potential 
personal injury.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the SNPRM (79 
FR 58294, September 29, 2014) and the FAA's response to each comment.

Support for the SNPRM (79 FR 58294, September 29, 2014)

    Boeing concurred with the contents of the SNPRM (79 FR 58294, 
September 29, 2014).

Requests To Remove Certain Provisions for Spare Parts

    American Airlines and UPS requested that we revise the SNPRM (79 FR 
58294, September 29, 2014) by removing paragraph (q), because its 
provisions are redundant with the requirements of paragraph (k) of the 
SNPRM.
    We agree with the requests, for the reason provided by the 
commenters. We have removed the referenced paragraph and redesignated 
subsequent paragraphs accordingly.

Request To Clarify Replacement Requirements

    American Airlines requested that we revise the SNPRM (79 FR 58294, 
September 29, 2014) to identify the part numbers for fittings that are 
acceptable for terminating action, but to not require specific removal 
and reinstallation procedures. The commenter added that the design 
change of the fitting--not the installation method--corrects the unsafe 
condition.
    We partially agree with the request. Although we did not identify 
the part numbers, we revised paragraph (o) in this AD to specify only 
the specific step that provides the replacement instructions and 
identifies the part number of the new fittings. Other removal and 
reinstallation actions related to the fitting replacement may be done 
using accepted methods in accordance with the operator's maintenance or 
inspection program.
    We disagree with American Airlines' assertion that only the fitting 
design ``corrects the unsafe condition.'' ADs contain requirements that 
are related to addressing the unsafe condition, as determined by the 
FAA and the design approval holder that developed the service 
information. Therefore, many provisions of ADs address aspects of 
accomplishing the required maintenance that are necessary to prevent 
operators from inadvertently aggravating the unsafe condition or 
introducing new unsafe conditions. As in this case, the replacement 
instructions provided in the referenced service information are 
reasonably related to addressing the unsafe condition.
    As always, operators preferring to use a method other than that 
specified in the referenced service information may request approval 
for an alternative method of compliance and, if approved, may use it 
instead of the procedures specified in the service information.
    We further clarified this action throughout this AD by revising the 
description of the replacement part by specifying ``the inboard main 
flap outboard hinge fittings.''

Effect of Winglets on AD

    Aviation Partners Boeing, United Airlines, Delta Air Lines, and UPS 
requested that the SNPRM (79 FR 58294, September 29, 2014) specify that 
accomplishment of supplemental type certificate (STC) ST01920SE (http:/
/rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/
59027f43b9a7486e86257b1d006591ee/$FILE/ST01920SE.pdf) does not affect 
the actions in the SNPRM.
    We concur with the request. We have redesignated the introductory 
text of paragraph (c) of the SNPRM (79 FR 58294, September 29, 2014) as 
paragraph (c)(1), and subparagraphs (c)(1) and (c)(2) as (c)(1)(i) and 
(c)(1)(ii), and added new paragraph (c)(2) to this AD to state that 
installation of STC ST01920SE (http://rgl.faa.gov/
Regulatory_and_Guidance_Library/rgstc.nsf/0/
59027f43b9a7486e86257b1d006591ee/$FILE/ST01920SE.pdf) does not affect 
the ability to accomplish the actions required by this final rule. 
Therefore, for airplanes on which STC ST01920SE is installed, a 
``change in product'' alternative method of compliance (AMOC) approval 
request is not necessary to comply with the requirements of 14 CFR 
39.17.

Change of Location for Certain Credit Service Information

    We have removed Boeing Alert Service Bulletin 767-57A0079, Revision 
1, dated May 6, 2010, which is referred to for credit for certain 
actions, from paragraph (g)(2) of the proposed AD. Instead, we have 
revised paragraph (p)(1) of this AD to specifically provide credit for 
actions required by paragraph (g)(2) of this AD, if those actions were 
performed before the effective date of this AD using Boeing Alert 
Service Bulletin 767-57A0079, Revision 1, dated May 6, 2010. We have 
redesignated subsequent paragraphs (including the addition of new 
paragraph (p)(3)) accordingly. This change does not affect the intent 
of paragraph (g)(2) of this AD.

[[Page 61095]]

Change to Retained Credit for Previous Actions Language

    We have revised the wording in paragraph (l) of this AD; this 
change has not changed the intent of that paragraph.

Change to Previous AMOCs Paragraph

    We have added a reference to paragraph (j) of this AD in paragraph 
(q)(4) of this AD to account for any AMOCs that might have been 
approved for the optional action specified in paragraph (j) of this AD.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this 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 
SNPRM (79 FR 58294, September 29, 2014) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM (79 FR 58294, September 29, 2014).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 767-57A0079, Revision 2, 
dated March 23, 2012; and Boeing Alert Service Bulletin 767-57A0076, 
Revision 3, dated April 4, 2012. The service information describes 
procedures for repetitive eddy current inspections for cracks or 
fractures of the outboard hinge fitting assemblies on the trailing edge 
of the inboard main flap. The service information also describes 
procedures for replacing the fittings, which would eliminate the need 
for the repetitive inspections. This service information is reasonably 
available because the interested parties have access to it through 
their normal course of business or by the means identified in the 
ADDRESSES section of this final rule.

Costs of Compliance

    We estimate that this AD affects 440 airplanes of U.S. registry. We 
estimate the following costs to comply with this AD:

that would be required based on the results of the inspection. We have 
no way of determining the number of airplanes that might need these 
replacements:

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,
    (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.

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

0
1. The authority citation for part 39 continues to read as follows:

    Authority:  49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing Airworthiness Directive (AD) 
2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003), and adding 
the following new AD:


[[Page 61096]]


2015-15-06 The Boeing Company: Amendment 39-18215; Docket No. FAA-
2012-0108; Directorate Identifier 2011-NM-049-AD.

(a) Effective Date

    This AD is effective November 13, 2015.

(b) Affected ADs

    This AD replaces AD 2003-13-01, Amendment 39-13201 (68 FR 37402, 
June 24, 2003).

(c) Applicability

    (1) This AD applies to The Boeing Company airplanes, 
certificated in any category, identified in paragraphs (c)(1)(i) and 
(c)(1)(ii) of this AD.
    (i) Model 767-200, -300, and -300F series airplanes, as 
specified in Boeing Alert Service Bulletin 767-57A0076, Revision 3, 
dated April 4, 2012.
    (ii) Model 767-400ER series airplanes, as specified in Boeing 
Alert Service Bulletin 767-57A0079, Revision 2, dated March 23, 
2012.
    (2) Installation of Supplemental Type Certificate (STC) 
ST01920SE (http://rgl.faa.gov/Regulatory_and_Guidance_Library/
rgstc.nsf/0/59027f43b9a7486e86257b1d006591ee/$FILE/ST01920SE.pdf) 
does not affect the ability to accomplish the actions required by 
this AD. Therefore, for airplanes on which STC ST01920SE is 
installed, a ``change in product'' alternative method of compliance 
(AMOC) approval request is not necessary to comply with the 
requirements of 14 CFR 39.17.

(d) Subject

    Air Transport Association (ATA) of America Code 57, Wings.

(e) Unsafe Condition

    This AD was prompted by reports of hinge assembly fractures 
found before certain required compliance times on airplanes subject 
to AD 2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003). 
We are issuing this AD to prevent the inboard aft flap from 
separating from the wing and potentially striking the airplane, 
which could result in damage to the surrounding structure and 
potential personal injury.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Retained Inspection, With Revised Service Information

    This paragraph restates the requirements of paragraph (a) of AD 
2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003), with 
revised service information. Perform either a detailed inspection, 
or a detailed inspection plus an eddy current inspection, of the 
outboard hinge fitting assemblies on the trailing edge of the 
inboard main flap to detect cracks and fractures and evidence of a 
tool runout option, as applicable. For the purposes of this AD, a 
detailed inspection is defined as an intensive visual examination of 
a specific structural area, system, installation, or assembly to 
detect damage, failure, or irregularity. Available lighting is 
normally supplemented with a direct source of good lighting at 
intensity deemed appropriate by the inspector. Inspection aids such 
as mirror, magnifying lenses, etc., may be used. Surface cleaning 
and elaborate access procedures may be required.
    (1) For Model 767-200, -300, and -300F series airplanes 
identified in Boeing Service Bulletin 767-57A0076, Revision 1, dated 
March 29, 2001: Inspect before the airplane accumulates 2,700 total 
flight cycles, or within 90 days after July 29, 2003 (the effective 
date of AD 2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 
2003)), whichever occurs later, in accordance with Boeing Service 
Bulletin 767-57A0076, Revision 1, dated March 29, 2001; or the 
Accomplishment Instructions of Boeing Alert Service Bulletin 767-
57A0076, Revision 3, dated April 4, 2012. As of the effective date 
of this AD, only Boeing Service Bulletin 767-57A0076, Revision 3, 
dated April 4, 2012, may be used for the inspection.
    (2) For Model 767-400ER series airplanes identified in Boeing 
Alert Service Bulletin 767-57A0079, dated June 20, 2002: Inspect 
before the airplane accumulates 12,000 total flight cycles, except 
as required by paragraph (m) of this AD, in accordance with Boeing 
Alert Service Bulletin 767-57A0079, dated June 20, 2002; or the 
Accomplishment Instructions of Boeing Alert Service Bulletin 767-
57A0079, Revision 2, dated March 23, 2012. As of the effective date 
of this AD, only Boeing Alert Service Bulletin 767-57A0079, Revision 
2, dated March 23, 2012, may be used for the inspection.

(h) Retained Follow-On/Corrective Actions, With Revised Service 
Information

    This paragraph restates the requirements of paragraph (b) of AD 
2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003), with 
revised service information. Following the initial inspections 
required by paragraph (g) of this AD, perform applicable follow-on 
and corrective actions at the times specified in Figure 1 of Boeing 
Service Bulletin 767-57A0076, Revision 1, dated March 29, 2001 (for 
Model 767-200, -300, and -300F series airplanes); or Boeing Alert 
Service Bulletin 767-57A0079, dated June 20, 2002 (for Model 767-
400ER series airplanes); until the initial inspection required by 
paragraph (n) of this AD is accomplished, and repeat thereafter at 
the applicable times specified in paragraph (n) of this AD. Do the 
follow-on and corrective actions (including repetitive inspections 
and replacement of the fittings with new fittings) in accordance 
with Part 1 or Part 2 of Boeing Service Bulletin 767-57A0076, 
Revision 1, dated March 29, 2001; or Boeing Alert Service Bulletin 
767-57A0079, dated June 20, 2002; or in accordance with the 
Accomplishment Instructions of the service information identified in 
paragraph (h)(1) or (h)(2) of this AD; except as required by 
paragraph (i)(2) of this AD. For Model 767-200, -300, and -300F 
series airplanes: If the fitting has the tool runout, and no 
cracking or fracture is found during the inspection, this AD 
requires no further action for that hinge fitting. As of the 
effective date of this AD, for the actions required by this 
paragraph, only the service information identified in paragraph 
(h)(1) or (h)(2) of this AD, as applicable, may be used.
    (1) Boeing Service Bulletin 767-57A0076, Revision 3, dated April 
4, 2012 (for Model 767-200, -300, and -300F series airplanes).
    (2) Boeing Alert Service Bulletin 767-57A0079, Revision 2, dated 
March 23, 2012 (for Model 767-400ER series airplanes).

(i) Retained Exceptions to Service Bulletin Procedures, Without the 
Reporting Requirement and With Revised Service Information

    This paragraph restates the requirements of paragraphs (c) and 
(d) of AD 2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 
2003), without the reporting requirement and with revised service 
information. The following exceptions specified in paragraphs (i)(1) 
and (i)(2) of this AD apply.
    (1) Where the terminating action in Part 3 of Boeing Service 
Bulletin 767-57A0076, Revision 1, dated March 29, 2001, and Revision 
3, dated April 4, 2012; and Boeing Alert Service Bulletin 767-
57A0079, dated June 20, 2002, and Revision 2, dated March 23, 2012; 
as applicable; is specified as corrective action, this AD requires 
that the terminating action, if required, be accomplished before 
further flight.
    (2) Boeing Service Bulletin 767-57A0076, Revision 1, dated March 
29, 2001; and Boeing Alert Service Bulletin 767-57A0076, Revision 3, 
dated April 4, 2012; specify to contact Boeing before the 
terminating action is done as corrective action for any cracking or 
fracture found on a Model 767-200, -300, or -300F series airplane

    This paragraph restates the provisions of paragraph (f) of AD 
2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003). Unless 
required to do so by paragraph (h) of this AD, operators may choose 
to accomplish the terminating action (including replacement of the 
fittings with new fittings, and reinstallation of existing upper 
skin access panels and fairing midsections on the trailing edge of 
the main flap) in accordance with Part 3 of the Work Instructions of 
Boeing Service Bulletin 767-57A0076, Revision 1, dated March 29, 
2001; or Boeing Alert Service Bulletin 767-57A0079, dated June 20, 
2002; as applicable; or do the terminating actions specified in 
paragraph (o) of this AD. As of the effective date of this AD, use 
only the terminating action specified in paragraph (o) of this AD. 
Accomplishment of the terminating action terminates the repetitive 
inspection requirements of paragraph (h) of this AD.
