We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 737-400 series airplanes, as modified by a certain supplemental type certificate. This proposed AD was prompted by the discovery of a design drawing error regarding placards that identified incorrect squibs and pressure switches for certain fire extinguisher bottles. This proposed AD would require a detailed inspection of certain cargo placards to determine if they are the correct placards and in the correct location, a detailed inspection of the harnesses to verify that they are marked and installed correctly, and corrective action if necessary. We are proposing this AD to detect and correct incorrectly installed harnesses for the cargo fire suppression system bottles, which could result in an incorrect activation sequence of the bottles, the inability to suppress a cargo fire quickly, and a possible uncontrollable fire.

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 737-400 series airplanes, as modified 
by a certain supplemental type certificate. This proposed AD was 
prompted by the discovery of a design drawing error regarding placards 
that identified incorrect squibs and pressure switches for certain fire 
extinguisher bottles. This proposed AD would require a detailed 
inspection of certain cargo placards to determine if they are the 
correct placards and in the correct location, a detailed inspection of 
the harnesses to verify that they are marked and installed correctly, 
and corrective action if necessary. We are proposing this AD to detect 
and correct incorrectly installed harnesses for the cargo fire 
suppression system bottles, which could result in an incorrect 
activation sequence of the bottles, the inability to suppress a cargo 
fire quickly, and a possible uncontrollable fire.

Discussion

    We have received a report of a design drawing error regarding the 
placement of placards that identify the squibs and pressure switches 
for halon fire extinguisher bottles Number 1 and Number 2. Electrical 
harnesses for the cargo fire suppression system bottles may 
consequently be reversed, which would cause an incorrect activation 
sequence of the bottles, i.e., the initial high-rate ``knockdown'' 
agent discharge will not be released until after a 5-minute time delay 
rather than immediately as intended. This condition, if not corrected, 
could result in an incorrect activation sequence of the bottles, the 
inability to suppress a cargo fire quickly, and a possible 
uncontrollable fire.

Related Service Information Under 1 CFR Part 51

    We reviewed Advanced Aircraft Extinguishers Service Bulletin TFA10-
26-0020, Revision IR, dated January 12, 2015. The service information 
describes procedures for a detailed inspection of Advanced Aircraft 
Extinguishers (AAE) cargo fire protection system (FPS) placards to 
determine if they are the correct placards and in the correct location, 
and a detailed inspection of

[[Page 38034]]

the harnesses to verify that they are marked and installed correctly. 
The service information also describes corrective actions such as 
removing the existing AAE cargo FPS placards, destroying/discarding 
them, and installing AAE-provided cargo FPS placards on the mounting 
plate. 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 of this 
NPRM.

Clarification of Service Information Procedures

    Step C.(3) of the ``SERVICE BULLETIN INSTRUCTIONS'' of Advanced 
Aircraft Extinguishers Service Bulletin TFA10-26-0020, Revision IR, 
dated January 12, 2015, does not clearly state the corrective action 
for the inspection of the harnesses. Therefore, paragraph (h) of this 
proposed AD specifies the steps in the service information that would 
be required if any harness is not marked correctly or not installed 
correctly.

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.''

Differences Between This Proposed AD and the Service Information

    While Advanced Aircraft Extinguishers Service Bulletin TFA10-26-
0020, Revision IR, dated January 12, 2015, specifies a compliance time 
of 30 days, this proposed AD would require a compliance time of 6 
months. In developing an appropriate compliance time for this AD, we 
considered the degree of urgency associated with the subject unsafe 
condition, the average utilization of the affected fleet, and the time 
necessary to perform the inspection. In light of all of these factors, 
we find that 6 months represents an appropriate interval of time for 
affected airplanes to continue to operate without compromising safety. 
This difference has been coordinated with Boeing and AAE.
    The ``EFFECTIVITY'' section of Advanced Aircraft Extinguishers 
Service Bulletin TFA10-26-0020, Revision IR, dated January 12, 2015, 
lists serial number (S/N) 24132 in the ``Purchased for Installation on 
Aircraft Serial Number'' column. This is a typographical error in the 
service information. The Applicability section of this proposed AD 
correctly identifies S/N 24231.

Explanation of ``RC'' Steps in Service Information

    The FAA worked in conjunction with industry, under the 
Airworthiness Directive 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.
    For service information that contains steps that are labeled as 
Required for Compliance (RC), the following provisions apply: (1) 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, 
and an AMOC is required for any deviations to RC steps, including 
substeps and identified figures; and (2) 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.

Costs of Compliance

    We estimate that this proposed AD affects 3 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                       Cost on
               Action                        Labor cost               Parts cost          Cost per       U.S.
                                                                                          product     operators
----------------------------------------------------------------------------------------------------------------
Detailed inspection.................  2 work-hours x $85 per   N/A....................         $170         $510
                                       hour = $170.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary corrective 
actions 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 corrective actions:

                           On-Condition Costs
------------------------------------------------------------------------
                                                     Parts     Cost per
             Action                  Labor cost       cost     product
------------------------------------------------------------------------
Corrective actions.............  2 work-hours x        $900       $1,070
                                  $85 per hour =
                                  $170.
------------------------------------------------------------------------

    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue rules on aviation safety. Subtitle I,

[[Page 38035]]

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.
