14 CFR Part 39
[Docket No. FAA-2019-0525; Product Identifier 2019-NM-076-AD]
RIN 2120-AA64
Airworthiness Directives; The Boeing Company Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD)
2006-11-11, which applies to all The Boeing Company Model 757
airplanes. AD 2006-11-11 requires incorporating a new revision to the
Airworthiness Limitations section of the Instructions of Continued
Airworthiness to mandate certain repetitive inspections for fatigue
cracking of principal structural elements (PSEs). Since AD 2006-11-11
was issued, the FAA has determined that new or more restrictive
airworthiness limitations are necessary. This proposed AD would require
revising the existing maintenance or inspection program, as applicable,
to incorporate new or more restrictive airworthiness limitations. The
FAA is proposing this AD to address the unsafe condition on these
products.
DATES: The FAA must receive comments on this proposed AD by September
9, 2019.

Discussion
The FAA issued AD 2006-11-11, Amendment 39-14615 (71 FR 30278, May
26, 2006) (``AD 2006-11-11''), for all The Boeing Company Model 757
airplanes. AD 2006-11-11 requires incorporating a new revision to the
Airworthiness Limitations section of the Instructions of Continued
Airworthiness to mandate certain repetitive inspections for fatigue
cracking of PSEs. AD 2006-11-11 resulted from a new revision to the
Airworthiness Limitations Instructions (ALI). The FAA issued AD 2006-
11-11 to address fatigue cracking of various PSEs; such fatigue
cracking could adversely affect the structural integrity of these
airplanes.
Actions Since AD 2006-11-11 Was Issued
Since AD 2006-11-11 was issued, the FAA has determined that new or
more restrictive airworthiness limitations are necessary.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Boeing 757 Maintenance Planning Data (MPD)
Document, Section 9, Airworthiness Limitations (AWLs) and Certification
Maintenance Requirements (CMRs), D622N001-9, Revision October 2018.
This service information describes procedures for airworthiness
limitations for structural inspections, fuel tank systems, safe life
limits, and certification maintenance requirements.
This proposed AD would also require the following service
information, which the Director of the Federal Register approved for
incorporation by reference as of June 30, 2006 (71 FR 30278, May 26,
2006).
Boeing 757 Maintenance Planning Data (MPD) Document,
Section 9, ``Airworthiness Limitations and Certification Maintenance
Requirements,'' Subsection B. of Boeing Document D622N001-9, Revision
``May 2003.''
[[Page 35841]]
Boeing 757 Maintenance Planning Data (MPD) Document,
Section 9, ``Airworthiness Limitations and Certification Maintenance
Requirements,'' Subsection B. of Boeing Document D622N001-9, Revision
``June 2005.''
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
The FAA is 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 retain all requirements of AD 2006-11-11.
This proposed AD would require revising the existing maintenance or
inspection program, as applicable, to incorporate new or more
restrictive airworthiness limitations, which would then terminate all
of the retained requirements of AD 2006-11-11.
This proposed AD would require revisions to certain operator
maintenance or inspection documents, as applicable, to include new
actions (e.g., inspections) and Critical Design Configuration Control
Limitations (CDCCLs). Compliance with these actions and CDCCLs is
required by 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 may 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 paragraph (l) of this proposed AD.
Costs of Compliance
The FAA estimates that this proposed AD affects 561 airplanes of
U.S. registry. The FAA estimates the following costs to comply with
this proposed AD.
The retained and new actions specified in this proposed AD have the
same cost for revising the existing maintenance or inspection program.
The FAA has determined that revising the existing maintenance or
inspection program takes an average of 90 work-hours per operator,
although the agency recognizes that this number may vary from operator
to operator. In the past, the FAA has estimated that this action takes
1 work-hour per airplane. Since operators incorporate maintenance or
inspection program changes for their affected fleet(s), the FAA has
determined that a per-operator estimate is more accurate than a per-
airplane estimate. Therefore, the FAA estimates the total cost per
operator to be $7,650 (90 work-hours x $85 per work-hour).
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.
The FAA is 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.
This proposed AD is issued in accordance with authority delegated
by the Executive Director, Aircraft Certification Service, as
authorized by FAA Order 8000.51C. In accordance with that order,
issuance of ADs is normally a function of the Compliance and
Airworthiness Division, but during this transition period, the
Executive Director has delegated the authority to issue ADs applicable
to transport category airplanes and associated appliances to the
Director of the System Oversight Division.
Regulatory Findings
The FAA has 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) Will not affect intrastate aviation in Alaska, and
(3) 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:
