We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 727 airplanes. This proposed AD was prompted by a report of cracking in the inboard lower flange and adjacent web near the forward attachment of the outboard flap track at a certain position on a Model 737-300 airplane. The flap tracks of Model 737-300 airplanes are similar to the flap tracks of Model 727 airplanes. This proposed AD would require repetitive detailed inspections and surface high frequency eddy current (HFEC) inspections of each outboard flap track at certain positions for any crack and discrepancy, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
The Boeing Company Model 727 airplanes. This proposed AD was prompted 
by a report of cracking in the inboard lower flange and adjacent web 
near the forward attachment of the outboard flap track at a certain 
position on a Model 737-300 airplane. The flap tracks of Model 737-300 
airplanes are similar to the flap tracks of Model 727 airplanes. This 
proposed AD would require repetitive detailed inspections and surface 
high frequency eddy current (HFEC) inspections of each outboard flap 
track at certain positions for any crack and discrepancy, and 
applicable on-condition actions. We are proposing this AD to address 
the unsafe condition on these products.

Discussion

    We have received a report indicating cracking in the inboard lower 
flange and adjacent web near the forward attachment of the outboard 
flap track at position 8, which was found during a tear down of a Model 
737-300 airplane. The flap tracks of Model 737-300 airplanes are 
similar to the flap tracks of Model 727 airplanes. This condition, if 
not addressed, could result in the inability of a principal structural 
element to sustain required flight load, which could result in loss of 
the outboard trailing edge flap and reduced controllability of the 
airplane.

Related Rulemaking

    We have issued AD 2018-18-13, Amendment 39-19392 (83 FR 46380, 
September 13, 2018) (``AD 2018-18-13''), for The Boeing Company Model 
737-100, -200, -200C, -300, -400, -500 series airplanes. AD 2018-18-13 
requires an inspection to determine the part number of the wing 
outboard flap track assembly; repetitive inspections of each affected 
wing outboard flap track for discrepancies, and applicable on-condition 
actions; and repetitive overhaul of each wing outboard flap track. AD 
2018-18-13 addresses cracking of the rear spar attachment, and cracking 
of the wing outboard flap tracks. Cracking in the area between the 
forward and rear spar attachments of the wing outboard flap tracks 
could lead to the inability of a principal structural element to 
sustain required flight load, and result in loss of the outboard 
trailing edge flap and consequent reduced controllability of the 
airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Requirements Bulletin 727-57A0188 RB, 
dated May 31, 2018. The service information describes procedures for 
repetitive detailed inspections for discrepancies and surface HFEC 
inspections for cracks of each outboard flap track at positions 1, 2, 
7, and 8, and applicable on-condition actions. On-condition actions 
include repairs and installation of a new or serviceable flap track. 
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 accomplishment of the actions 
identified in Boeing Alert Requirements Bulletin 727-57A0188 RB, dated 
May 31, 2018, described previously, except for any differences 
identified as exceptions in the regulatory text of this proposed AD.
    For information on the procedures and compliance times, see this 
service information at http://www.regulations.gov by searching for and 
locating Docket No. FAA-2018-0803.

Explanation of Requirements Bulletin

    The FAA worked in conjunction with industry, under the 
Airworthiness Directives Implementation Aviation Rulemaking Committee 
(AD ARC), to enhance the AD system. One enhancement is a process for 
annotating which steps in the service information are ``required for 
compliance'' (RC) with

[[Page 49019]]

an AD. Boeing has implemented this RC concept into Boeing service 
bulletins.
    In an effort to further improve the quality of ADs and AD-related 
Boeing service information, a joint process improvement initiative was 
worked between the FAA and Boeing. The initiative resulted in the 
development of a new process in which the service information more 
clearly identifies the actions needed to address the unsafe condition 
in the ``Accomplishment Instructions.'' The new process results in a 
Boeing Requirements Bulletin, which contains only the actions needed to 
address the unsafe condition (i.e., only the RC actions).

Costs of Compliance

    We estimate that this proposed AD affects 16 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

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

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in 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, 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

    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

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

The Boeing Company: Docket No. FAA-2018-0803; Product Identifier 
2018-NM-098-AD.

(a) Comments Due Date

    We must receive comments by November 13, 2018.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to all The Boeing Company Model 727, 727-100,

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Required Actions

    Except as required by paragraph (h) of this AD: At the 
applicable times specified in the ``Compliance'' paragraph of Boeing 
Alert Requirements Bulletin 727-57A0188 RB, dated May 31, 2018, do 
all applicable actions identified in, and in accordance with, the 
Accomplishment Instructions of Boeing Alert Requirements Bulletin 
727-57A0188 RB, dated May 31, 2018.

    Note 1 to paragraph (g) of this AD:  Guidance for accomplishing 
the actions required by this AD can be found in Boeing Alert Service 
Bulletin 727-57A0188, dated May 31, 2018, which is referred to in 
Boeing Alert Requirements Bulletin 727-57A0188 RB, dated May 31, 
2018.

(h) Exceptions to Service Information Specifications

    (1) For purposes of determining compliance with the requirements 
of this AD: Where Boeing Alert Requirements Bulletin 727-57A0188 RB, 
dated May 31, 2018, uses the phrase ``the original issue date of 
Requirements Bulletin 727-57A0188 RB,'' this AD requires using ``the 
effective date of this AD.''

[[Page 49020]]

    (2) Where Boeing Requirements Bulletin 727-57A0188 RB, dated May 
31, 2018, specifies contacting Boeing for repair instructions, this 
AD requires repair before further flight using a method approved in 
accordance with the procedures specified in paragraph (j) of this 
AD.

(i) Parts Installation Limitation

    As of the effective date of this AD, no person may install, on 
any airplane, a wing outboard flap track having a part number listed 
in paragraph 1.B. of Boeing Alert Requirements Bulletin 727-57A0188 
RB, dated May 31, 2018, unless the inspections and applicable on-
condition actions specified in the Accomplishment Instructions of 
Boeing Alert Requirements Bulletin 727-57A0188 RB, dated May 31, 
2018, are accomplished concurrently with the installation of the 
part on the airplane.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles ACO Branch, 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 certification office, send it to the attention of 
the person identified in paragraph (k)(1) of this AD. Information 
may be emailed to: [email protected].
    (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 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair, modification, or alteration required by this AD 
if it is approved by the Boeing Commercial Airplanes Organization 
Designation Authorization (ODA) that has been authorized by the 
Manager, Los Angeles ACO Branch, FAA, to make those findings. To be 
approved, the repair method, modification deviation, or alteration 
deviation must meet the certification basis of the airplane, and the
