Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) 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. This proposed AD was prompted by a report of 
incidents involving fatigue cracking in transport category airplanes 
that are approaching or have exceeded their design service objective 
and a structural reevaluation by the manufacturer that identified 
additional structural elements that qualify as structural significant 
items (SSIs). This proposed AD would require revising the maintenance 
or inspection program, as applicable, to include inspections that will 
give no less than the required damage tolerance rating (DTR) for 
certain SSIs, and repairing any cracked structure. This proposed AD 
would also require inspections to detect cracks of all SSI structure, 
and repair if necessary. We are proposing this AD to ensure the 
continued structural integrity of 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.

Discussion

    On December 26, 2007, we issued AD 2004-07-22 R1, Amendment 39-
15326 (73 FR 1052, January 7, 2008); corrected February 14, 2008 (73 FR 
8589) (``AD 2004-07-22 R1''); 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 2004-07-22 R1 
requires that the maintenance inspection program be revised to include 
inspections that will give no less than the required DTR for each SSI, 
and repair of cracked structure. AD 2004-07-22 R1 was prompted by a 
report of incidents involving fatigue cracking in transport category 
airplanes that are approaching or have exceeded their design service 
objective. We issued AD 2004-07-22 R1 to ensure the continued 
structural integrity of all Boeing 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.

Actions Since AD 2004-07-22 R1 Was Issued

    Since we issued AD 2004-07-22 R1, a structural reevaluation by the 
manufacturer identified additional structural elements that qualify as 
SSIs. We have determined that supplemental inspections are required for 
timely detection of fatigue cracking for these additional structural 
elements.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Document No. D6-35022, ``Supplemental Structural 
Inspection Document for Model 747 Airplanes,'' Revision H, dated 
September 2013. The service information describes procedures for 
inspections to detect cracks of all structure identified as SSIs and 
includes six new SSIs since the last revision.
    We also reviewed Boeing Document No. D6-35022-1, ``747-400 LCF 
Supplemental Structural Inspection Document--Appendix A,'' dated 
November 2015. The service information describes procedures for 
inspections of wing, fuselage, and empennage SSIs for Model 747-400 LCF 
airplanes.
    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.

FAA's Determination

    We are proposing this AD 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.

Proposed AD Requirements

    This proposed AD would require revising the maintenance or 
inspection program, as applicable, to include inspections that will 
give no less than the required DTR for certain SSIs, and repairing any 
cracked structure. This proposed AD would also require inspections to 
detect cracks of all SSI structure, and repair if necessary.
    This proposed AD does not supersede 2004-07-22 R1. However, 
accomplishing the revision specified in paragraph (h) of this proposed 
AD would terminate the requirements of paragraphs (f), (g), and (h) of 
AD 2004-07-22 R1. Also, doing an inspection specified in paragraph (i) 
of this proposed AD would terminate the corresponding inspection 
required by paragraph (i) of AD 2004-07-22 R1.

Costs of Compliance

    We estimate that this proposed AD affects 118 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per      Cost on  U.S.
               Action                        Labor cost           Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
Revision of maintenance or            1 work-hour x $85 per                $0              $85          $10,030
 inspection program.                   hour = $85.
----------------------------------------------------------------------------------------------------------------

    We have not specified cost estimates for the inspection and repair 
specified in this proposed AD. Compliance with this proposed AD 
constitutes a method of compliance with the FAA aging airplane safety 
final rule (AASFR) (70 FR 5518, February 2, 2005) for certain baseline 
structure of 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 AASFR requires certain operators to incorporate damage 
tolerance inspections into their maintenance inspection programs. These 
requirements are described in 14 CFR 121.1109(c)(1) and 14 CFR 
129.109(b)(1). Accomplishment of the actions specified in this proposed 
AD will meet the requirements of these regulations for certain baseline 
structure. The costs for accomplishing the inspection portion of this 
proposed AD were accounted for in the regulatory evaluation of the 
AASFR.

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.

[[Page 62033]]

    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.

(k) Repair

    If any cracked structure is found during any inspection required 
by paragraph (i) or (j) of this AD, repair before further flight 
using a method approved in accordance with the procedures specified 
in paragraph (m) of this AD.

(l) Inspection Program for Transferred Airplanes

    Before any airplane that is subject to this AD and that has 
exceeded the applicable compliance times specified in paragraph (i) 
or (j) of this AD can be added to an air carrier's operations 
specifications, a program for the accomplishment of the inspections 
required by this AD must be established in accordance with paragraph 
(l)(1) or (l)(2) of this AD, as applicable.
    (1) For airplanes that have been inspected as specified in this 
AD, the inspection of each SSI must be accomplished by the new 
operator using the previous operator's schedule and inspection 
method, or the new operator's schedule and inspection method, at 
whichever time would result in the earlier accomplishment for that 
SSI inspection. The compliance time for accomplishment of this 
inspection must be measured from the last inspection accomplished by 
the previous operator. After each inspection has been performed 
once, each subsequent inspection must be performed using the new 
operator's schedule and inspection method.
    (2) For airplanes that have not been inspected as specified in 
this AD, the inspection of each SSI required by this AD must be 
accomplished either prior to adding the airplane to the air 
carrier's operations specification, or using a schedule and an 
inspection method approved by the Manager, Seattle Aircraft 
Certification Office (ACO). After each inspection has been performed 
once, each subsequent inspection must be performed using the new 
operator's schedule and inspection method.

(m) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle 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 CFR 39.19, send your request to your 
principal inspector or local Flight Standards District Office, as 
appropriate. If sending information directly to the manager of the 
ACO, send it to the attention of the person identified in paragraph 
(n)(1) of this AD. Information may be emailed to: 9-ANM-Seattle-ACO-
AMOC-Requests@faa.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding
