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 
certain The Boeing Company Model 737-300, -400, and -500 series 
airplanes. This proposed AD was prompted by a report of fatigue 
cracking found in a certain fuselage frame common to the water tank 
support intercostal clip located between certain stringers. This 
proposed AD would require inspections for any cracking of a certain 
fuselage frame, and repair if necessary. We are proposing this AD to 
address the unsafe condition on these products.

Discussion

    We have received a report of fatigue cracking found in a certain 
fuselage frame, Station (STA) 947.5 on the right side, common to the 
water tank support intercostal clip located between certain stringers, 
S-24R and S-25R. Ten cracks were reported on airplanes having line

[[Page 14836]]

numbers 2566 through 3132. Those airplanes had accumulated between 
39,400 and 51,745 total flight cycles. The reported cracks were between 
0.184 and 1.125 inch long. These cracks were found to be caused by 
fatigue caused by cyclic loading of the fuselage, and out-of-plane 
bending of the frame caused by the water tank loads. Fatigue cracking, 
if not corrected, could grow in size and result in a severed frame. 
Multiple adjacent severed frames would result in reduced structural 
integrity of the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 737-53A1357, dated August 
9, 2016. The service information describes procedures for inspections 
for any cracking of a certain fuselage frame, and repair if necessary. 
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 accomplishing the actions specified 
in the service information described previously. 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-2017-
0131.

Costs of Compliance

    We estimate that this proposed AD affects 140 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

    We estimate the following costs to do any necessary repairs 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 this 
repair:

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 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.

[[Page 14837]]

(d) Subject

    Air Transport Association (ATA) of America Code 53; Fuselage.

(e) Unsafe Condition

    This AD was prompted by a report of fatigue cracking found in a 
certain fuselage frame common to the water tank support intercostal 
clip located between certain stringers. We are issuing this AD to 
detect and correct cracking, which could grow in size and result in 
a severed frame. Multiple adjacent severed frames would result in 
reduced structural integrity of the airplane.

(f) Compliance

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

(g) Inspection

    Before the accumulation of 34,000 total flight cycles or within 
6,000 flight cycles after the effective date of this AD, whichever 
occurs later, do a high frequency eddy current (HFEC) inspection for 
any cracking in the fuselage frame at station (STA) 947.5 common to 
the water tank support intercostal clip located between stringer S-
24R and S-25R, in accordance with the Accomplishment Instructions of 
Boeing Alert Service Bulletin 737-53A1357, dated August 9, 2016.
    (1) If no cracking is found, repeat the inspection thereafter at 
intervals not to exceed 12,000 flight cycles.
    (2) If any cracking is found: Before further flight, repair in 
accordance with the Accomplishment Instructions of Boeing Alert 
Service Bulletin 737-53A1357, dated August 9, 2016.

(h) Terminating Action

    Accomplishing the repair in accordance with the Accomplishment 
Instructions of Boeing Alert Service Bulletin 737-53A1357, dated 
August 9, 2016, terminates the inspection requirements of paragraph 
(g) of this AD.

(i) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Los Angeles 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 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 (j)(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, 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 approval 
must specifically refer to this AD.
    (4) For service information that contains steps that are labeled 
as Required for Compliance (RC), the provisions of paragraphs 
(i)(4)(i) and (i)(4)(ii) of this AD apply.
    (i) The steps labeled as RC, including substeps under an RC step 
and any figures identified in an RC step, must be done to comply 
with the AD. If a step or substep is labeled ``RC Exempt,'' then the 
RC requirement is removed from that step or substep. An AMOC is 
required for any deviations to RC steps, including substeps and 
identified figures.
    (ii) Steps not labeled as RC may be deviated from using accepted 
methods in accordance with the operator's maintenance or inspection 
program without obtaining approval of an AMOC, provided the RC 
steps, including substeps and identified figures, can still be done 
as specified, and the airplane can be put back in an airworthy 
condition.
