ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to supersede airworthiness directive (AD) 89–12–10, which applies to certain The Boeing Company Model 747 series airplanes. SUMMARY: E:\FR\FM\25SEP1.SGM 25SEP1 TKELLEY on DSK3SPTVN1PROD with PROPOSALS Federal Register / Vol. 78, No. 186 / Wednesday, September 25, 2013 / Proposed Rules AD 89–12–10 currently requires replacement of certain underwing fuel tank access doors with stronger, fireresistant doors. Since we issued AD 89– 12–10, we have received reports indicating that a standard access door was located where an impact-resistant access door was required, and stencils were missing from some impactresistant access doors. Stencils are required to indicate that the door is impact-resistant and to indicate the correct location for installation of the impact-resistant door. This proposed AD would require an inspection of the left- and right-hand wing fuel tank access doors to determine whether impact-resistant access doors are installed in the correct locations, and replacement of any door with an impact-resistant access door if necessary. This proposed AD would also require an inspection for the presence of stencils and index markers on impact-resistant access doors, and application of new stencils or index markers if necessary. This proposed AD would also require revising the maintenance program to incorporate changes to the airworthiness limitations section. This proposed AD would also add airplanes to the applicability. We are proposing this AD to prevent foreign object penetration of the fuel tank, which could cause a fuel leak near an ignition source (e.g., hot brakes or engine exhaust nozzle), consequently leading to a fuel-fed fire. DATES: We must receive comments on this proposed AD by November 12, 2013. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to http://www.regulations.gov.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. 58963 AD 89–12–10 to prevent a fire in the wing fuel tank. Actions Since AD 89–12–10 Was Issued Since we issued AD 89–12–10, additional access doors, that may be installed on additional airplanes that were not identified in AD 89–12–10, have been identified that may be subject to the unsafe condition. Certain doors are addressed in other service bulletins. Additionally, due to repainting of the lower wing skin, stencils that identify the access door may no longer be in place to provide a visual confirmation that the correct door is installed. Relevant Service Information We reviewed the following service information. For information on the procedures and compliance times, see this service information at http:// www.regulations.gov by searching for Docket No. FAA–2013–0790. • Boeing Service Bulletin 747–28– 2315, dated January 11, 2012. • CDCCL Task 57–AWL–01, ‘‘ImpactResistant Fuel Tank Access Doors,’’ of Sub-section B, Airworthiness Limitations (AWLs)—Fuel Systems, of Section 9, Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs) of Boeing 747– 400 Maintenance Planning Data (MPD) Document D621U400, Revision August 2012. • CDCCL Task 57–AWL–01, ‘‘ImpactResistant Fuel Tank Access Doors,’’ of Sub-section C, Airworthiness Limitations—Fuel Systems, of the Boeing 747–100/200/300/SP Airworthiness Limitations (AWLs) and Certification Maintenance Requirements (CMRs) Document D6–13747–CMR, Revision August 2012. FAA’s Determination We are proposing this AD because we evaluated all the relevant information and determined the unsafe condition identified previously is likely to exist or develop in other products of these same type designs. Discussion Proposed AD Requirements On May 22, 1989, we issued AD 89– 12–10, Amendment 39–6230 (54 FR 23643, June 2, 1989) (‘‘AD 89–12–10’’), for certain The Boeing Company Model 747–100, 747–200, 747–300, and 747– SP series airplanes. AD 89–12–10 requires replacement of certain underwing fuel tank access doors with stronger, fire-resistant doors. AD 89–12– 10 resulted from several incidents of door penetration by tire and engine debris, which resulted in spillage of significant quantities of fuel. We issued This proposed AD would retain none of the requirements of AD 89–12–10. Since that AD was issued, the FAA issued section 121.316 of the Federal Aviation Regulations (14 CFR 121.316) requiring that each turbine-powered transport category airplane meet the requirements of section 25.963(e) of the Federal Aviation Regulations (14 CFR 25.963(e)). Section 25.963(e) outlines the certification requirements for fuel tank access covers on turbine powered transport category airplanes. PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 E:\FR\FM\25SEP1.SGM 25SEP1 58964 Federal Register / Vol. 78, No. 186 / Wednesday, September 25, 2013 / Proposed Rules This proposed AD would require accomplishing the actions specified in the service information described previously. This proposed AD would add Models 747–400, 747–400D, 747– 400F, and 747SR series airplanes to the applicability, and clarify the applicability of AD 89–12–10, Amendment 39–6230 (54 FR 23643, June 2, 1989) to identify models listed in the current type certification data sheets (TCDS). This proposed AD would also require inspecting fuel tank access doors to determine that impact-resistant access doors are installed in the correct locations and replacing any door with an impact-resistant access door if necessary; inspecting application of stencils and index markers of impact- resistant access doors and application of new stencils or index markers if necessary; and revising the maintenance program. This proposed AD requires revisions to certain operator maintenance documents to include a new CDCCL. Compliance with CDCCLs is required by section 91.403(c) of the Federal Aviation Regulations (14 CFR 91.403(c)). For airplanes that have been previously modified, altered, or repaired in the areas addressed by this proposed AD, the operator might not be able to accomplish the actions described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to the procedures specified in paragraph (j) of this proposed AD. The request should include a description of changes to the required actions that will ensure the continued damage tolerance of the affected structure. After accomplishment of the revision required by paragraph (h) of this AD, no alternative actions (e.g., inspections), intervals, and/or CDCCLs may be used unless the actions, intervals, and/or CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j) of this AD. Costs of Compliance We estimate that this proposed AD affects 189 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Inspection .................................................. Up to 13 work-hours × $85 per hour = $1,105. 1 work-hour × $85 per hour = $85. Maintenance program revision .................. We estimate the following costs to do any necessary replacements that would Parts cost Cost per product Cost on U.S. operators $0 Up to $1,105 ........... Up to $208,845. 0 85 ............................ 16,065. 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: ON-CONDITION COSTS Action Labor cost Replacement per door ........................................................................ Stencil and index marker (14 doors) .................................................. 3 work-hours × $85 per hour = $255 ..... 17 work-hours × $85 per hour = $1,445 According to the manufacturer, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all costs in our cost estimate. TKELLEY on DSK3SPTVN1PROD with PROPOSALS 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 VerDate Mar<15>2010 16:14 Sep 24, 2013 Jkt 229001 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 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 that the 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), PO 00000 Frm 00009 Fmt 4702 Sfmt 4702 Parts cost Cost per product $8,000 0 $8,255 1,445 (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.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to supersede airworthiness directive (AD) 89-12-10, 
which applies to certain The Boeing Company Model 747 series airplanes.

[[Page 58963]]

AD 89-12-10 currently requires replacement of certain underwing fuel 
tank access doors with stronger, fire-resistant doors. Since we issued 
AD 89-12-10, we have received reports indicating that a standard access 
door was located where an impact-resistant access door was required, 
and stencils were missing from some impact-resistant access doors. 
Stencils are required to indicate that the door is impact-resistant and 
to indicate the correct location for installation of the impact-
resistant door. This proposed AD would require an inspection of the 
left- and right-hand wing fuel tank access doors to determine whether 
impact-resistant access doors are installed in the correct locations, 
and replacement of any door with an impact-resistant access door if 
necessary. This proposed AD would also require an inspection for the 
presence of stencils and index markers on impact-resistant access 
doors, and application of new stencils or index markers if necessary. 
This proposed AD would also require revising the maintenance program to 
incorporate changes to the airworthiness limitations section. This 
proposed AD would also add airplanes to the applicability. We are 
proposing this AD to prevent foreign object penetration of the fuel 
tank, which could cause a fuel leak near an ignition source (e.g., hot 
brakes or engine exhaust nozzle), consequently leading to a fuel-fed 
fire.

Discussion

    On May 22, 1989, we issued AD 89-12-10, Amendment 39-6230 (54 FR 
23643, June 2, 1989) (``AD 89-12-10''), for certain The Boeing Company 
Model 747-100, 747-200, 747-300, and 747-SP series airplanes. AD 89-12-
10 requires replacement of certain underwing fuel tank access doors 
with stronger, fire-resistant doors. AD 89-12-10 resulted from several 
incidents of door penetration by tire and engine debris, which resulted 
in spillage of significant quantities of fuel. We issued AD 89-12-10 to 
prevent a fire in the wing fuel tank.

Actions Since AD 89-12-10 Was Issued

    Since we issued AD 89-12-10, additional access doors, that may be 
installed on additional airplanes that were not identified in AD 89-12-
10, have been identified that may be subject to the unsafe condition. 
Certain doors are addressed in other service bulletins. Additionally, 
due to repainting of the lower wing skin, stencils that identify the 
access door may no longer be in place to provide a visual confirmation 
that the correct door is installed.

Relevant Service Information

    We reviewed the following service information. For information on 
the procedures and compliance times, see this service information at 
http://www.regulations.gov by searching for Docket No. FAA-2013-0790.

Doors,'' of Sub-section B, Airworthiness Limitations (AWLs)--Fuel 
Systems, of Section 9, Airworthiness Limitations (AWLs) and 
Certification Maintenance Requirements (CMRs) of Boeing 747-400 
Maintenance Planning Data (MPD) Document D621U400, Revision August

Certification Maintenance Requirements (CMRs) Document D6-13747-CMR, 
Revision August 2012.

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition identified previously 
is likely to exist or develop in other products of these same type 
designs.

Proposed AD Requirements

    This proposed AD would retain none of the requirements of AD 89-12-
10. Since that AD was issued, the FAA issued section 121.316 of the 
Federal Aviation Regulations (14 CFR 121.316) requiring that each 
turbine-powered transport category airplane meet the requirements of 
section 25.963(e) of the Federal Aviation Regulations (14 CFR 
25.963(e)). Section 25.963(e) outlines the certification requirements 
for fuel tank access covers on turbine powered transport category 
airplanes.

[[Page 58964]]

    This proposed AD would require accomplishing the actions specified 
in the service information described previously. This proposed AD would 
add Models 747-400, 747-400D, 747-400F, and 747SR series airplanes to 
the applicability, and clarify the applicability of AD 89-12-10, 
Amendment 39-6230 (54 FR 23643, June 2, 1989) to identify models listed 
in the current type certification data sheets (TCDS).
    This proposed AD would also require inspecting fuel tank access 
doors to determine that impact-resistant access doors are installed in 
the correct locations and replacing any door with an impact-resistant 
access door if necessary; inspecting application of stencils and index 
markers of impact-resistant access doors and application of new 
stencils or index markers if necessary; and revising the maintenance 
program.
    This proposed AD requires revisions to certain operator maintenance 
documents to include a new CDCCL. Compliance with CDCCLs is required by 
section 91.403(c) of the Federal Aviation Regulations (14 CFR 
91.403(c)). For airplanes that have been previously modified, altered, 
or repaired in the areas addressed by this proposed AD, the operator 
might not be able to accomplish the actions described in the revisions. 
In this situation, to comply with 14 CFR 91.403(c), the operator must 
request approval for an alternative method of compliance according to 
the procedures specified in paragraph (j) of this proposed AD. The 
request should include a description of changes to the required actions 
that will ensure the continued damage tolerance of the affected 
structure.
    After accomplishment of the revision required by paragraph (h) of 
this AD, no alternative actions (e.g., inspections), intervals, and/or 
CDCCLs may be used unless the actions, intervals, and/or CDCCLs are 
approved as an alternative method of compliance (AMOC) in accordance 
with the procedures specified in paragraph (j) of this AD.

Costs of Compliance

    We estimate that this proposed AD affects 189 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                 Cost on U.S.
             Action                    Labor cost         Parts cost      Cost per product        operators

                                   x $85 per hour =
                                   $1,105.
Maintenance program revision....  1 work-hour x $85                  0  85.................  16,065.
                                   per hour = $85.
----------------------------------------------------------------------------------------------------------------

    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:

                                               On-condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                 Labor cost               Parts cost        product

                                                 $255.
Stencil and index marker (14 doors)...........  17 work-hours x $85 per hour =                 0           1,445
                                                 $1,445.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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 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 that the 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.

[[Page 58965]]

Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by removing airworthiness directive (AD) 
89-12-10, Amendment 39-6230 (54 FR 23643, June 2, 1989), and adding the 
following new AD:

The Boeing Company: Docket No. FAA-2013-0790; Directorate Identifier 
2013-NM-061-AD.

(a) Comments Due Date

    The FAA must receive comments on this AD action by November 12, 
2013.

(b) Affected ADs

    This AD supersedes AD 89-12-10, Amendment 39-6230 (54 FR 23643, 
June 2, 1989).

(c) Applicability

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

actions specified in paragraphs (g)(1) and (g)(2) of this AD, in 
accordance with the Accomplishment Instructions of Boeing Service 
Bulletin 747-28-2315, dated January 11, 2012.
    (1) Do either a general visual inspection or ultrasonic non-
destructive test of the left- and right-hand wing fuel tank access 
doors to determine whether impact-resistant access doors are 
installed in the correct locations. If any standard access door is 
found, before further flight, replace with an impact-resistant 
access door, in accordance with the Accomplishment Instructions of 
Boeing Service Bulletin 747-28-2315, dated January 11, 2012.
    (2) Do a general visual inspection of the left- and right-hand 
wing fuel tank impact resistant access doors to verify stencils and

Maintenance Requirements (CMRs) Document D6-13747-CMR, Revision 
August 2012.

(i) No Alternative Actions, Intervals, and/or Critical Design 
Configuration Control Limitations (CDCCLs)

    After accomplishing the revision required by paragraph (h) of 
this AD, no alternative actions (e.g., inspections), intervals, and/
or CDCCLs may be used unless the actions, intervals, and/or CDCCLs 
are approved as an alternative method of compliance (AMOC) in 
accordance with the procedures specified in paragraph (j) of this 
AD.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14
