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 737-100, -200, and -200C series 
airplanes. This proposed AD is intended to complete certain mandated 
programs intended to support the airplane reaching its limit of 
validity (LOV) of the engineering data that support the established 
structural maintenance program. This proposed AD would require 
repetitive detailed, high frequency eddy current (HFEC), and ultrasonic 
inspections of the center section rear spar upper clevis lugs and 
horizontal stabilizer rear spar upper lugs, as applicable, for any 
cracking, and related investigative and corrective actions if 
necessary. For certain airplanes, this proposed AD would require 
replacement of the center section rear spar upper chord with a new part 
and a serviceable center section assembly. This proposed AD would also 
require repetitive HFEC and fluorescent dye penetrant inspections of 
the center section for cracking of the front and rear spar upper clevis 
lugs or horizontal stabilizer front and rear spar upper lugs, and 
related investigative and corrective actions if necessary. We are 
proposing this AD to detect and correct cracking in the rear spar upper 
clevis lugs of the center section, and in the rear spar upper lugs of 
the horizontal stabilizer which could result in the loss of structural 
integrity and controllability of the airplane.

DATES: We must receive comments on this proposed AD by August 26, 2016.

Discussion

    As described in FAA Advisory Circular 120-104 (http://www.faa.gov/documentLibrary/media/Advisory_Circular/120-104.pdf), several programs 
have been developed to support initiatives that will ensure the 
continued airworthiness of aging airplane structure. The last element 
of those initiatives is the requirement to establish a LOV of the 
engineering data that support the structural maintenance program under 
14 CFR 26.21. This proposed AD is the result of an assessment of the 
previously established programs by the DAH during the process of 
establishing the LOV for the affected airplanes. The actions specified 
in this proposed AD are necessary to complete certain programs to 
ensure the continued airworthiness of aging airplane structure and to 
support an airplane reaching its LOV.
    This proposed AD is intended to complete certain mandated programs 
intended to support the airplane reaching its LOV of the engineering 
data that support the established structural maintenance program. An 
operator detected a cracked center section at the rear spar upper chord 
clevis lug. This condition, if not corrected, could result in cracking 
in the rear spar clevis lugs of the horizontal stabilizer center 
section, which could result in loss of structural integrity and 
controllability of the airplane.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 737-55A1033, Revision 2, 
dated August 7, 2015. The service information describes procedures for 
repetitive detailed, HFEC, and ultrasonic inspections of the center 
section rear spar upper clevis lugs and rear spar upper lugs of the 
horizontal stabilizer; HFEC and fluorescent dye penetrant inspections 
for cracking in the front and rear spar upper clevis lugs of the center 
section and the front and rear spar upper lugs of the horizontal 
stabilizer. For certain airplanes, the service information describes 
procedures for replacement of the center section rear spar upper chord 
with a new part and replacing the center section with a serviceable 
center section assembly, or installing bushings and sleeves as 
applicable. 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, except as discussed 
under ``Differences Between This Proposed AD and the Service 
Information.'' 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-2016-7426.
    The phrase ``related investigative actions'' is used in this NPRM. 
Related investigative actions are follow-on actions that (1) are 
related to the primary action, and (2) further investigate the nature 
of any condition found. Related investigative actions in an AD could 
include, for example, inspections.
    The phrase ``corrective actions'' is also used in this NPRM. 
Corrective actions are actions that correct or address any condition 
found. Corrective actions in an AD could include, for example, repairs.

Differences Between This Proposed AD and the Service Information

    Boeing Alert Service Bulletin 737-55A1033, Revision 2, dated August 
7, 2015, specifies to contact the manufacturer for certain 
instructions, but this proposed AD would require accomplishment of 
repair methods, modification deviations, and alteration deviations in 
one of the following ways:
     In accordance with a method that we approve; or
     Using data that meet the certification basis of the 
airplane, and that have been approved by the Boeing Commercial 
Airplanes Organization Designation Authorization (ODA) whom we have 
authorized to make those findings.
    Where Boeing Alert Service Bulletin 737-55A1033, Revision 2, dated 
August 7, 2015, specifies a compliance time or repeat interval as 
``Horizontal Stabilizer Center Section flight cycles'' or ``Horizontal 
Stabilizer flight cycles,'' this AD requires compliance for the 
corresponding time or repeat interval in airplane flight cycles.

Costs of Compliance

    We estimate that this proposed AD affects 84 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 inspections, 
repairs, and 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 inspections, repairs, and replacements:

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.
