Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Supplemental notice of proposed rulemaking (NPRM); reopening of 
comment period.

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) for certain The Boeing Company Model 767 airplanes. The NPRM 
proposed to supersede AD 2003-13-01, which currently requires 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 also requires inspecting to determine if a tool runout option has 
been performed in the area. The NPRM proposed to reduce a certain 
compliance time and adds airplanes to the applicability. The NPRM also 
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. This action revises 
the NPRM by reducing repetitive inspection intervals for certain 
airplanes and limiting the inspection area. We are proposing this 
supplemental NPRM (SNPRM) 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. Since these actions impose an additional burden over 
that proposed in the NPRM, we are reopening the comment period to allow 
the public the chance to comment on these proposed changes.

DATES: We must receive comments on this SNPRM by November 13, 2014.

Discussion

    We issued an NPRM to amend 14 CFR part 39 by adding an AD that 
would apply to certain The Boeing Company Model 767-200, -300, and -
300F, and -400ER series airplanes. The NPRM published in the Federal 
Register on February 9, 2012 (77 FR 6685). The NPRM proposed to 
supersede AD 2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 
2003). 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; and, for certain airplanes, a one-time inspection 
to determine if a tool runout option has been performed in the area. 
The NPRM also reduced compliance times on certain airplanes (Model 767-
400ER series airplanes), revised the applicability, and added an 
optional terminating action.

Actions Since Previous NPRM (77 FR 6685, February 9, 2012) Was Issued

    Since we issued the NPRM (77 FR 6685, February 9, 2012), we have 
received reports of hinge assembly fractures found before the current 
inspection interval on Model 767-200, -300, and -300F series airplanes.

Comments

    We gave the public the opportunity to comment on the NPRM (77 FR 
6685, February 9, 2012). The following presents the comments received 
on the NPRM and the FAA's response to each comment.

Support for the NPRM (77 FR 6685, February 9, 2012)

    An anonymous commenter supported the NPRM (77 FR 6685, February 9, 
2012).

Request To Revise Applicability

    American Airlines requested that we revise the applicability of the 
NPRM (77 FR 6685, February 9, 2012) to identify specific flap serial 
numbers instead of airplane line numbers. The commenter stated that a 
flap removed from the hinge assembly could then be installed on a 
different airplane.
    We partially agree. We agree that the subject flaps are rotable 
parts that may be removed and reinstalled on different

[[Page 58295]]

airplanes after compliance with the AD. We have therefore added new 
paragraph (q) in this SNPRM (and redesignated subsequent paragraphs) to 
prohibit installation of an inboard main flap unless it has been 
inspected and repaired in accordance with the requirements of this 
SNPRM. But we do not agree to change the applicability as requested 
because this AD action applies to the airplane, not a component.
    Since the flight cycles on the flaps may not be tracked by some 
operators, we mandated a compliance time tied to the total flight 
cycles of the airplane. Operators may request approval of an 
alternative compliance time, however, if the actual accumulated flight 
cycles on reinstalled flaps are known.

Request To Specify Additional Airplanes Subject to Repetitive 
Inspection Requirement

    Boeing noted that paragraph (n) of the NPRM (77 FR 6685, February 
9, 2012) specifies repetitive detailed and/or eddy current inspections 
for Model 767-400ER series airplanes. Boeing requested that we revise 
paragraph (n) of the NPRM to add the following revised service 
information: Boeing Alert Service Bulletin 767-57A0076, Revision 3, 
dated April 4, 2012 (for Models 767-200, -300, and -300F airplanes); 
and Boeing Alert Service Bulletin 767-57A0079, Revision 2, dated March 
23, 2012 (for Model 767-400ER series airplanes). Boeing noted that this 
revised service information improves crack detection by clarifying the 
HFEC inspection area, based on a recent finding of a crack located 
along the edge of the inspection area on a Model 767-300 series 
airplane. We infer that Boeing wants us to revise paragraph (n) of the 
NPRM to add Model 767-200, -300, and -300F series airplanes.
    In addition, paragraph (o) of the NPRM (77 FR 6685, February 9, 
2012) specifies a new optional terminating action. Boeing requested 
that we revise that paragraph to include terminating action for Model 
767-200, -300, and -300F series airplanes (in addition to Model 767-
400ER series airplanes), and to refer to Boeing Alert Service Bulletins 
767-57A0076, Revision 3, dated April 4, 2012; and 767-57A0079, Revision 
2, dated March 23, 2012.
    Further, Boeing requested that we revise paragraph (p) of the NPRM 
(77 FR 6685, February 9, 2012) to provide credit for previous actions 
done using Boeing Service Bulletin 767-57A0076, Revision 2, dated 
November 22, 2006; and Boeing Service Bulletin 767-57A0079, Revision 1, 
dated May 6, 2010.
    We agree with the requests, for the reasons provided by the 
commenter. We have revised paragraphs (n) and (o) in this SNPRM to add 
the referenced airplanes and service information. For information on 
the procedures and compliance times, see Boeing Alert Service Bulletin 
767-57A0076, Revision 3, dated April 4, 2012; and 767-57A0079, Revision 
2, dated March 23, 2012; at http://www.regulations.gov by searching for 
and locating Docket No. FAA-2012-0108.
    We also have revised paragraph (p) of this SNPRM to provide credit 
for Boeing Service Bulletin 767-57A0076, Revision 2, dated November 22, 
2006; and Boeing Service Bulletin 767-57A0079, Revision 1, dated May 6, 
2010. We have determined that accomplishment of the actions specified 
in this revised service information before the effective date of the AD 
would provide an adequate level of safety.

Request for Approval of AMOCs

    Boeing, American Airlines, and UPS requested that AMOCs previously 
approved for paragraph (i) of AD 2003-13-01, Amendment 39-13201 (68 FR 
37402, June 24, 2003), be considered acceptable for compliance with the 
requirements of paragraphs (g), (h), and (i) of the NPRM (77 FR 6685, 
February 9, 2012).
    We agree. We have determined that the referenced AMOCs would 
provide an adequate level of safety. We have included this provision in 
new paragraph (r)(4) of this SNPRM.

FAA's Determination

    We are proposing this SNPRM because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design. 
Certain changes described above expand the scope of the NPRM (77 FR 
6685, February 9, 2012). As a result, we have determined that it is 
necessary to reopen the comment period to provide additional 
opportunity for the public to comment on this SNPRM.

Proposed Requirements of This SNPRM

    This SNPRM would require accomplishing the actions specified in 
Boeing Alert Service Bulletin 767-57A0076, Revision 3, dated April 4, 
2012; and 767-57A0079, Revision 2, dated March 23, 2012.

Costs of Compliance

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

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------

                                     per inspection cycle.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary replacements 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of aircraft 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 determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 proposed 
regulation:
    (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),
    (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

(g) Retained Inspection

    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.

Alert Service Bulletin 767-57A0079, Revision 2, dated March 23, 
2012, may be used for the inspection.

(h) Retained Follow-On/Corrective Actions

    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 Service Bulletin 767-
57A0076, Revision 3, dated April 4, 2012 (for Model 767-200, -300,

series airplanes); 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 Boeing Alert Service Bulletin 767-
57A0079, Revision 2, dated March 23, 2012, may be used for Model 
767-400ER series airplanes; and only Boeing Alert Service Bulletin 
767-57A0076,

[[Page 58297]]

Revision 3, dated April 4, 2012, may be used for Model 767-200, -
300, and -300F airplanes.

(i) Retained Exceptions to Service Bulletin Procedures

    This paragraph restates the requirements of paragraph (c) of AD 
2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003). 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; Revision 1, dated May 6, 2010; 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 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 with the tool runout. However, this AD requires 
that any such crack or fracture on those airplanes be repaired in 
accordance with Part 3 of Boeing Service Bulletin 767-57A0076, 
Revision 1, dated March 29, 2001; or Revision 3, dated April 4, 
2012. This AD does not require a report.

(j) Retained Optional Terminating Action

    This paragraph restates the provisions of paragraph (f) of AD 
2003-13-01, Amendment 39-13201 (68 FR 37402, June 24, 2003), with 
revised service information. 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
