We are revising an earlier proposed airworthiness directive (AD) that proposed to supersede AD 2006-22-15 for all The Boeing Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747- 200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series airplanes. AD 2006-22-15 requires repetitive inspections for cracking of certain panel webs and stiffeners of the nose wheel well (NWW), and corrective actions if necessary; and replacement of certain panels with new panels, which terminates the repetitive inspections. The notice of proposed rulemaking (NPRM) proposed to reduce a compliance time and add certain inspections and applicable repair. The NPRM was prompted by reports of fatigue cracking in the panel webs and stiffeners of the NWW found prior to the inspection threshold of AD 2006-22-15. This action revises the NPRM by specifying a repetitive inspection interval for a certain NWW area inspection. We are proposing this SNPRM to prevent fatigue cracking of the NWW side and top panels, which could result in a NWW depressurization event severe enough to reduce the structural integrity of the fuselage. 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.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

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

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

SUMMARY: We are revising an earlier proposed airworthiness directive 
(AD) that proposed to supersede AD 2006-22-15 for all The Boeing 
Company Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-200C, 747-
200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP series 
airplanes. AD 2006-22-15 requires repetitive inspections for cracking 
of certain panel webs and stiffeners of the nose wheel well (NWW), and 
corrective actions if necessary; and replacement of certain panels with 
new panels, which terminates the repetitive inspections. The notice of 
proposed rulemaking (NPRM) proposed to reduce a compliance time and add 
certain inspections and applicable repair. The NPRM was prompted by 
reports of fatigue cracking in the panel webs and stiffeners of the NWW 
found prior to the inspection threshold of AD 2006-22-15. This action 
revises the NPRM by specifying a repetitive inspection interval for a 
certain NWW area inspection. We are proposing this SNPRM to prevent 
fatigue cracking of the NWW side and top panels, which could result in 
a NWW depressurization event severe enough to reduce the structural 
integrity of the fuselage. 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.

Discussion

    We issued an NPRM to amend 14 CFR part 39 to supersede AD 2006-22-
15, Amendment 39-14812 (71 FR 64884, November 6, 2006). AD 2006-22-15 
applies to all Model 747-100, 747-100B, 747-100B SUD, 747-200B, 747-
200C, 747-200F, 747-300, 747-400, 747-400D, 747-400F, 747SR, and 747SP 
series airplanes. The NPRM published in the Federal Register on 
November 17, 2014 (79 FR 68388). The NPRM was prompted by reports of 
fatigue cracking in the panel webs and stiffeners of the NWW found 
prior to the inspection threshold of AD 2006-22-15. The NPRM proposed 
to continue to require repetitive inspections for cracking of certain 
panel webs and stiffeners of the NWW, and corrective actions if 
necessary. The NPRM also proposed to continue to require replacing 
certain panels with new panels, which would terminate the repetitive 
inspections. The NPRM proposed to reduce a compliance time and add 
certain inspections and applicable repair.

Actions Since Previous NPRM (79 FR 68388, November 17, 2014) Was Issued

    Since we issued the NPRM (79 FR 68388, November 17, 2014), we have 
determined that it is necessary to revise the NPRM by specifying a 
certain repetitive inspection interval for Area 2 for airplanes with 
less than 15,000 total flight cycles. This interval is not clearly 
indicated in table 1 of paragraph 1.E., ``Compliance,'' of Boeing 
Service Bulletin 747-53A2465, Revision 5, dated July 11, 2013, and was 
not specifically stated in the NPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed the following Boeing service information. Refer to this 
service information for information on the procedures and compliance 
times.
     Boeing Service Bulletin 747-53A2465, Revision 5, dated 
July 11, 2013, which describes procedures for inspections for cracks of 
certain top and sidewall panel webs and stiffeners of the NWW; and 
repairs.
     Boeing Service Bulletin 747-53A2562, Revision 3, dated 
July 11, 2013. This service bulletin describes procedures for 
replacement of the side and top panel webs and certain stiffeners of 
the NWW; an inspection for cracks in attaching structural elements that 
are common to the removed top panel and side panels; repetitive post-
modification inspections for cracks in the top and side panel webs and 
stiffeners; and contacting Boeing for repairs.
     Boeing Alert Service Bulletin 747-53A2808, dated November 
30, 2012. This service bulletin describes procedures for replacement of 
the side and top panel webs, support beams, and stiffeners of the NWW; 
an inspection for cracks of the attaching structural elements that are 
common to the removed top and side panels of the NWW; repetitive post-
modification inspections for cracks in the top and side panel webs and 
stiffeners; and contacting Boeing for repairs.
    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 
AD.

Comments

    We gave the public the opportunity to comment on the NPRM (79 FR 
68388, November 17, 2014). The following presents the comments received 
on the NPRM and the FAA's response to each comment.

Requests To Specify Repetitive Inspection Interval for Area 2

    United Airlines (UAL) and United Parcel Service (UPS) requested 
that we specify the repetitive inspection interval for Area 2 for 
airplanes with less than 15,000 total flight cycles. The commenters 
point out that this is not clearly indicated in table 1 of paragraph 
1.E., ``Compliance,'' of Boeing Service Bulletin 747-53A2465, Revision 
5, dated July 11, 2013, and was not specifically stated in the NPRM (79 
FR 68388, November 17, 2014). The commenters stated that Boeing has 
issued a service bulletin information notice to inform operators that 
the repetitive inspection interval for Area 2 should be 1,000 flight 
cycles.
    We agree with the commenters' requests to specify the repeat 
interval for Area 2. We have revised paragraph (g) of this SNPRM to 
specify this interval.

Request To Specify Repair Procedures

    UAL asked whether paragraph (h)(3) of the proposed AD (79 FR 68388, 
November 17, 2014) should be revised to specify repair requirements for 
each area, instead of contacting the FAA or the Boeing Commercial 
Airplanes Organization Designation Authorization (ODA) for repair 
instructions for any cracking or damage found during the inspection 
specified in paragraph (g) of the proposed AD. UAL explained that 
Boeing Service Bulletin 747-53A2465, Revision 5, dated July 11, 2013, 
specifies repairing web cracks in Area 1 or 2 per the ``747 Structural 
Repair Manuals.''
    We agree to provide clarification. The intent of paragraph (h)(3) 
of this SNPRM is to make sure that for those conditions for which 
Boeing Service Bulletin 747-53A2465, Revision 5, dated July 11, 2013, 
specifies that the operator is to contact Boeing for repair data, the 
operator would be required to use a repair method approved by the FAA 
or Boeing Commercial Airplanes ODA. We have not changed this SNPRM in 
this regard.

[[Page 56409]]

Request To Clarify Certain Compliance Times

    UAL requested clarification of why the footnotes in table 2 of 
paragraph 1.E., ``Compliance,'' of Boeing Service Bulletin 747-53A2465, 
Revision 5, dated July 11, 2013, reverted back to 6,000 flight cycles 
for Area 3 inspections for cracks of the sidewall panel and top panel 
stiffeners. UAL also asked why the 6,000-flight-cycle time is just for 
the first repeat inspection and then Area 3 has to be reinspected every 
1,500 flight cycles thereafter.
    We agree that clarification is necessary. Paragraph (f)(2) of AD 
2006-22-15, Amendment 39-14812 (71 FR 64884, November 6, 2006), 
specifies the 6,000-flight-cycle and 1,500-flight-cycle inspection 
times. Boeing Service Bulletin 747-53A2465, Revision 5, dated July 11, 
2013, states that inspections and corrective actions defined therein 
are an alternative method of compliance (AMOC) to the requirements of 
paragraphs (f), (g), (h), (i), and (j) of AD 2006-22-15. In order to be 
approved as an AMOC to certain requirements of AD 2006-22-15, Boeing 
Service Bulletin 747-53A2465, Revision 5, dated July 11, 2013, must 
state the compliance times required by AD 2006-22-15 to address the 
identified unsafe condition. We have not changed this SNPRM in this 
regard.

Request To Revise Certain Headers To Clarify Intent of Requirements

    Boeing requested that we revise the heading of paragraph (g) of the 
proposed AD (79 FR 68388, November 17, 2014) to either change 
``Repetitive Inspections'' to ``Initial and Repetitive Inspections'' or 
delete ``Repetitive.'' Boeing stated that paragraph (g) of the proposed 
AD contains both initial and repetitive inspections.
    Boeing requested that we delete ``Repetitive'' from the headings of 
paragraphs (j) and (m) of the proposed AD (79 FR 68388, November 17, 
2014). Boeing stated that paragraphs (j) and (m) of the proposed AD 
specify not only repetitive inspections, but also the initial post-
modification inspections.
    We agree that clarification is necessary. We do not consider that 
the term ``repetitive'' necessarily excludes the initial action. An 
action cannot be repeated without accomplishment of the initial action. 
Many existing ADs refer to ``repetitive'' actions, which we intend as 
including the initial action. In addition, changing ``Repetitive 
Inspections'' to simply ``Inspections'' could result in the 
misinterpretation that multiple different inspections are required. We 
have not changed this SNPRM regarding this issue.

Request To Clarify Inspection Location

    Boeing requested that, at the end of paragraph (g)(3) of the 
proposed AD (79 FR 68388, November 17, 2014), we add ``of the NWW 
(specified as Area 1 and Area 2 in Boeing Service Bulletin 747-53A2465, 
Revision 5, dated July 11, 2013)'' for the ultrasonic inspection.
    We agree with the commenter's request. This revision will make the 
wording in paragraph (g)(3) of this proposed AD consistent with the 
wording of each of the areas specified in paragraphs (g)(1) and (g)(2) 
of this proposed AD. We have revised paragraph (g)(3) of this proposed 
AD accordingly.

Request To Add New AMOC Limitation

    Boeing requested that we add a new paragraph (p)(6) to the NPRM (79 
FR 68388, November 17, 2014), which would state that ``New provisions 
(inspection threshold and interval) in this AD must be complied with as 
given in this AD.'' Boeing stated that this statement will make it 
clear that prior AMOCs do not exempt the operators from compliance with 
new requirements added by this new proposed AD. Boeing also stated that 
the wording of ``corresponding provisions'' in paragraph (p)(4) of the 
proposed AD (79 FR 68388, November 17, 2014) might not be precise 
enough, when ADs get superseded and paragraphs change. Boeing explained 
that adding this statement will reduce the ambiguity of paragraphs (o) 
and (p) of the proposed AD.
    We partially agree with the commenter's request. We have revised 
paragraph (p)(4) of this proposed AD to state that AMOC actions 
approved previously for AD 2006-22-15, Amendment 39-14812 (71 FR 64884, 
November 6, 2006), are approved as AMOCs for the corresponding actions 
of this AD. The compliance times in AMOCs approved previously for AD 
2006-22-15 are not approved for the corresponding actions and 
compliance times in this AD. We have removed paragraph (p)(5) of this 
proposed AD as it is no longer necessary. We consider this language to 
be sufficiently clear. Adding the commenter's requested language would 
be redundant to the language specified in revised paragraph (p)(4) of 
this proposed AD.

Requests for Certain Editorial Changes

    Boeing noted that paragraph (m) of the proposed AD (79 FR 68388, 
November 17, 2014) incorrectly referred to paragraphs ``(l)(1), (l)(2), 
and (l)(3).'' Boeing asked that we change these references to ``(m)(1), 
(m)(2), and (m)(3).''
    Boeing requested that we correct the AD citation in paragraph 
(o)(1)(i) of the proposed AD (79 FR 68388, November 17, 2014). Boeing 
stated that the identified effective date of January 27, 2005, is for 
AD 2004-25-23, Amendment 39-13911 (69 FR 76839, December 23, 2004); not 
AD 2005-09-02, Amendment 39-14070 (70 FR 21141, April 25, 2005; 
corrected May 25, 2005, 70 FR 29940)); as stated in the NPRM.
    Boeing requested that we correct the date of Boeing Service 
Bulletin 747-53A2465, Revision 4, from February 25, 2004, to February 
24, 2005, in paragraph (o)(2) of the proposed AD (79 FR 68388, November 
17, 2014).
    UPS requested that we revise paragraph (p)(1) of the proposed AD 
(79 FR 68388, November 17, 2014) to correct the paragraph identifier 
for the contact person, which should be paragraph ``(q)(1).''
    We agree with the requests and have revised this SNPRM accordingly.

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 this same type design. 
Certain changes described above expand the scope of the NPRM (79 FR 
68388, November 17, 2014). 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

    Although this proposed AD does not explicitly restate certain 
requirements of AD 2006-22-15, Amendment 39-14812 (71 FR 64884, 
November 6, 2006), this proposed AD would retain all of the 
requirements of AD 2006-22-15.
    The requirements specified in paragraphs (f), (g), (h), (i), (j), 
and (l) of AD 2006-22-15, Amendment 39-14812 (71 FR 64884, November 6, 
2006), are referenced in Boeing Service Bulletin 747-53A2465, Revision 
5, dated July 11, 2013, which, in turn, is referenced in paragraphs (g) 
and (h)(3) of this proposed AD.
    The requirement specified in paragraph (n) of AD 2006-22-15, 
Amendment 39-14812 (71 FR 64884, November 6, 2006), is referenced in 
Boeing Service Bulletin 747-53A2562, Revision 3, dated July 11, 2013, 
which, in turn, is referenced in paragraph (i) of this proposed AD.

[[Page 56410]]

    For Group 2 airplanes identified in Boeing Service Bulletin 747-
53A2562, Revision 1, dated July 28, 2005, and certain airplanes not 
identified in Boeing Service Bulletin 747-53A2562, Revision 1, dated 
July 28, 2005, the requirement specified in paragraph (o) of AD 2006-
22-15, Amendment 39-14812 (71 FR 64884, November 6, 2006), to 
accomplish a repair using a method approved by the FAA is now specified 
in paragraph (i) of this proposed AD. However, for these airplanes, one 
method of compliance for accomplishing the replacement is Boeing 
Service Bulletin 747-53A2562, Revision 3, dated July 11, 2013. 
Therefore, we have referred to Boeing Service Bulletin 747-53A2562, 
Revision 3, dated July 11, 2013, in paragraph (i) of this proposed AD. 
Operators may still request an alternative method of compliance (AMOC) 
using the procedures provided in paragraph (p) of this AD.
    For certain other airplanes not identified in Boeing Service 
Bulletin 747-53A2562, Revision 1, dated July 28, 2005, the requirement 
specified in paragraph (o) of AD 2006-22-15, Amendment 39-14812 (71 FR 
64884, November 6, 2006), to accomplish a repair using a method 
approved by the FAA is now specified in paragraph (l) of this proposed 
AD. However, for these airplanes, one method of compliance for 
accomplishing the replacement is Boeing Alert Service Bulletin 747-
53A2808, dated November 30, 2012. Therefore, we have referred to Boeing 
Alert Service Bulletin 747-53A2808, dated November 30, 2012, in 
paragraph (l) of this proposed AD. Operators may still request an AMOC 
using the procedures provided in paragraph (p) of this AD.
    This proposed AD would require accomplishing the actions specified 
in the service information identified previously, except as discussed 
under ``Differences Between the Proposed AD and the Service 
Information.'' Refer to this service information for information on the 
procedures and compliance times.
    The phrase ``related investigative actions'' is used in this 
proposed AD. ``Related investigative actions'' are follow-on actions 
that (1) are related to the primary actions, and (2) further 
investigate the nature of any condition found. Related investigative 
actions in an AD could include, for example, inspections.
    The phrase ``corrective actions'' is used in this proposed AD. 
``Corrective actions'' are actions that correct or address any 
condition found. Corrective actions in an AD could include, for 
example, repairs.

Differences Between the Proposed AD and the Service Information

    For airplanes with fewer than 15,000 total flight cycles, Boeing 
Service Bulletin 747-53A2465, Revision 5, dated July 11, 2013, 
recommends, in part, accomplishing a detailed inspection before the 
accumulation of 13,000 total flight cycles. However, we have determined 
that the 13,000-total-flight-cycle compliance time is insufficient to 
address the identified unsafe condition soon enough to ensure an 
adequate level of safety for the affected fleet. Instead, we are 
proposing a compliance time of 10,000 total flight cycles. In 
developing an appropriate compliance time for this detailed inspection, 
we considered the degree of urgency associated with the subject unsafe 
condition, and the fact that we have received a report of a 13-inch 
crack adjacent to a 2-inch crack in the NWW right-hand side panel on an 
airplane with 11,428 total flight cycles. This difference has been 
coordinated with The Boeing Company.
    Boeing Service Bulletin 747-53A2465, Revision 5, dated July 11, 
2013; Boeing Service Bulletin 747 53A2562, Revision 3, dated July 11, 
2013; and Boeing Alert Service Bulletin 747-53A2808, dated November 30, 
2012; specify to contact the manufacturer for instructions on how to 
repair certain conditions, but this proposed AD would require repairing 
those conditions in one of the following ways:
     In accordance with a method that we approve; or
     Using data that meet the certification basis of the 
airplane, and that have been approved by the Boeing Commercial 
Airplanes ODA whom we have authorized to make those findings.

Explanation of Compliance Time

    The compliance time for the modification specified in paragraphs 
(i) and (l) of this proposed AD for addressing widespread fatigue 
damage (WFD) was established to ensure that discrepant structure is 
modified before WFD develops in airplanes. Standard inspection 
techniques cannot be relied on to detect WFD before it becomes a hazard 
to flight. We will not grant any extensions of the compliance time to 
complete any AD-mandated service bulletin related to WFD without 
extensive new data that would substantiate and clearly warrant such an 
extension.

Costs of Compliance

    We estimate that this proposed AD affects 255 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed 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,

[[Page 56411]]

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

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 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 adding the following new airworthiness 
directive (AD):

The Boeing Company: Docket No. FAA-2014-0774; Directorate Identifier 
2013-NM-154-AD.

(a) Comments Due Date

    We must receive comments by November 2, 2015.

(b) Affected ADs

    This AD replaces AD 2006-22-15, Amendment 39-14812 (71 FR 64884, 
November 6, 2006).

(c) Applicability

    This AD applies to all Boeing Model 747-100, 747-100B, 747-100B 
SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400, 747-400D, 747-
