We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 737-600, -700, -700C, -800, -900, and -900ER series airplanes. This proposed AD was prompted by a determination that a repetitive test is needed to inspect the components on airplanes equipped with a certain air distribution system configuration. This proposed AD would require doing repetitive testing for correct operation of the equipment cooling system and low pressure environmental control system, and corrective actions if necessary. We are proposing this AD to detect and correct latent failures of the equipment cooling system and low pressure environmental control system, which could result in smoke in the flight deck and possible loss of aircraft control.

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 737-600, -700, -700C, -800, -900, and -900ER 
series airplanes. This proposed AD was prompted by a determination that 
a repetitive test is needed to inspect the components on airplanes 
equipped with a certain air distribution system configuration. This 
proposed AD would require doing repetitive testing for correct 
operation of the equipment cooling system and low pressure 
environmental control system, and corrective actions if necessary. We 
are proposing this AD to detect and correct latent failures of the 
equipment cooling system and low pressure environmental control system, 
which could result in smoke in the flight deck and possible loss of 
aircraft control.

Discussion

    We received a report indicating that a repetitive test is needed 
for inspection of the components on airplanes equipped with an air 
distribution system that was reconfigured using Boeing Special 
Attention Service Bulletin 737-26-1122, Revision 1, dated August 13, 
2009. Boeing Special Attention Service Bulletin 737-26-1122, Revision 
1, dated August 13, 2009, provided procedures for installing relays and 
diodes to the J24 junction box assembly and making wiring changes to 
the environmental control system. Without the repetitive test, failures 
of components could possibly be latent for extended periods. A cargo 
fire event, in conjunction with a latent failure of the air 
distribution system, can possibly result in smoke penetration into 
occupied areas. This condition, if not corrected, could result in smoke 
in the flight deck and possible loss of aircraft control.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Alert Service Bulletin 737-26A1137, dated May 
22, 2014. The service information describes procedures for repetitive 
testing for correct operation of the reconfigured equipment cooling 
system and low pressure environmental control system. Refer to this 
service information for information on the procedures and compliance 
times.
    Boeing Alert Service Bulletin 737-26A1137, dated May 22, 2014, 
specifies, for certain airplanes, prior or concurrent accomplishment of 
Boeing Special Attention 737-26-1122, Revision 1, dated August 13, 
2009. Boeing Special Attention 737-26-1122, Revision 1, dated August 
13, 2009, describes procedures for installing relays and diodes to the 
J24 junction box assembly and making wiring changes to the 
environmental control system.
    This service information is reasonably available; see ADDRESSES for 
ways to access this service information.

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.
    The phrase ``corrective actions'' is used in this proposed AD. 
``Corrective actions'' are actions that correct or address any 
condition found. Corrective actions in an AD could include, for 
example, repairs.

Explanation of Required for Compliance (RC) Steps in Service 
Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directives Implementation Aviation Rulemaking Committee 
(ARC), to enhance the AD system. One enhancement was a new process for 
annotating which steps in the service information are required for 
compliance with an AD. Differentiating these steps from other tasks in 
the service information is expected to improve an owner's/operator's 
understanding of crucial AD requirements and help provide consistent 
judgment in AD compliance. The steps identified as RC (required for 
compliance) in any service information identified previously have a 
direct effect on detecting, preventing, resolving, or eliminating an 
identified unsafe condition.
    Steps that are identified as RC in any service information must be 
done to comply with the proposed AD. However, steps that are not 
identified as RC are recommended. Those steps that are not identified 
as RC may be deviated from using accepted methods in accordance with 
the operator's maintenance or inspection program without obtaining 
approval of an alternative method of compliance (AMOC), provided the 
steps identified as RC can be done and the airplane can be put back in 
a serviceable condition. Any substitutions or changes to steps 
identified as RC will require approval of an AMOC.

[[Page 17370]]

Costs of Compliance

    We estimate that this proposed AD affects 1,372 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs

                                    cycle.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary isolation 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 replacements:

                                               On-Condition Costs

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.
