We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series airplanes. This AD was prompted by fuel system reviews conducted by the manufacturer. This AD requires installing an automatic shutoff system for the center and auxiliary tank fuel boost pumps, as applicable; installing a placard in the airplane flight deck if necessary; replacing the P5-2 fuel system module assembly; installing the ``uncommanded ON'' (UCO) protection system for the fuel boost pumps; revising the airplane flight manual (AFM) to advise the flight crew of certain operating restrictions for airplanes equipped with an automatic shutoff system; and revising the maintenance program by incorporating new airworthiness limitations for fuel tank systems to satisfy Special Federal Aviation Regulation No. 88 requirements. We are issuing this AD to prevent operation of the center and auxiliary tank fuel boost pumps with continuous low pressure, which could lead to friction sparks or overheating in the fuel pump inlet that could create a potential ignition source inside the center and auxiliary fuel tanks. These conditions, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane.

Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all The 
Boeing Company Model 737-100, -200, -200C, -300, -400, and -500 series 
airplanes. This AD was prompted by fuel system reviews conducted by the 
manufacturer. This AD requires installing an automatic shutoff system 
for the center and auxiliary tank fuel boost pumps, as applicable; 
installing a placard in the airplane flight deck if necessary; 
replacing the P5-2 fuel system module assembly; installing the 
``uncommanded ON'' (UCO) protection system for the fuel boost pumps; 
revising the airplane flight manual (AFM) to advise the flight crew of 
certain operating restrictions for airplanes equipped with an automatic 
shutoff system; and revising the maintenance program by incorporating 
new airworthiness limitations for fuel tank systems to satisfy Special 
Federal Aviation Regulation No. 88 requirements. We are issuing this AD 
to prevent operation of the center and auxiliary tank fuel boost pumps 
with continuous low pressure, which could lead to friction sparks or 
overheating in the fuel pump inlet that could create a potential 
ignition source inside the center and auxiliary fuel tanks. These 
conditions, in combination with flammable fuel vapors, could result in 
a fuel tank explosion and consequent loss of the airplane.

DATES: This AD is effective October 31, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of October 31, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 by adding an AD that would apply to all The Boeing 
Company Model 737-100, -200, -200C, -300, -400, and -500 series 
airplanes. The SNPRM published in the Federal Register on March 28, 
2016 (81 FR 17098) (``the SNPRM''). We preceded the SNPRM with a notice 
of proposed rulemaking (NPRM) that published in the Federal Register on 
October 12, 2011 (76 FR 63229) (``the NPRM''). The NPRM proposed to 
require installing an automatic shutoff system for the center and 
auxiliary tank fuel boost pumps, as applicable; installing a placard in 
the airplane flight deck if necessary; replacing the P5-2 fuel system 
module assembly; installing the UCO protection system for the fuel 
boost pumps; revising the airplane flight manual to advise the flight 
crew of certain operating restrictions for airplanes equipped with an 
automatic shutoff system; and revising the maintenance program by 
incorporating new airworthiness limitations for fuel tank systems to 
satisfy Special Federal Aviation Regulation No. 88 requirements. The 
NPRM was prompted by fuel system reviews conducted by the manufacturer. 
The SNPRM proposed to require updated or additional actions for certain 
airplane configurations. We are issuing this AD to prevent operation of 
the center and auxiliary tank fuel boost pumps with continuous low 
pressure, which could lead to friction sparks or overheating in the 
fuel pump inlet that could create a potential ignition source inside 
the center and auxiliary fuel tanks. These conditions, in combination 
with flammable fuel vapors, could result in a fuel tank explosion and 
consequent loss of the airplane.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments

[[Page 65865]]

received on the SNPRM and the FAA's response to each comment. Boeing 
concurred with the SNPRM.

Grouping Clarification for Airplanes With Removed Airstairs

    Phillippe Akot Azougo, ASLF, reported on a discussion with Boeing 
regarding the applicable airplane group for an airplane from which the 
airstair has been removed. Boeing indicated that if all of the support 
structure is not removed, the airplane is considered in the group with 
airstairs. Based on this comment, there is no need to change this final 
rule regarding this issue.

Effect of Winglets on Accomplishment of the Proposed Actions

    Aviation Partners Boeing stated that the installation of winglets 
per Supplemental Type Certificate (STC) ST01219SE does not affect the 
accomplishment of the manufacturer's service instructions.
    We agree with the commenter that STC ST01219SE does not affect the 
accomplishment of the manufacturer's service instructions. Therefore, 
the installation of STC ST01219SE does not affect the ability to 
accomplish the actions required by this AD. We have not changed this AD 
in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD as proposed, except for minor editorial changes. We have 
determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

We also determined that these changes will not increase the economic 
burden on any operator or increase the scope of this 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 AD will not have federalism implications under Executive Order 
13132. This AD will 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 that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under 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.

For ground operation, center tank fuel pump switches must not be positioned "ON" unless the center tank fuel quantity exceeds 1,000 pounds (453 kilograms), except when defueling or transferring fuel. Upon positioning the center tank fuel pump switches "ON," verify momentary illumination of each center tank fuel pump low pressure light. For ground and flight operations, the corresponding center tank fuel pump switch must be positioned "OFF" when a center tank fuel pump low pressure light illuminates [1]. Both center tank fuel pump switches must be positioned "OFF" when the first center tank fuel pump low pressure light illuminates ifthe center tank is empty. [1] When established in a level flight attitude, both center tank pump switches should be positioned "ON" again if the center tank contains usable fuel. DEFUELING AND FUEL TRANSFER When transferring fuel or defueling center or main tanks, the fuel pump low pressure lights must be monitored and the fuel pumps positioned to "OFF" at the first indication of the fuel pump low pressure [ 1]. Defueling the main tanks with passengers on board is prohibited ifthe main tank fuel pumps are powered [2]. Defueling the center tank with passengers on board is prohibited if the center tank fuel pumps are powered and the auto-shutoff system is inhibited [2]. [1] Prior to transferring fuel or defueling, conduct a lamp test of the respective fuel pump low pressure lights. [2] Fuel may be transferred from tank to tank or the aircraft may be defueled with passengers on board, provided fuel quantity in the tank from which fuel is being taken is maintained at or above 2,000 pounds (907 kilograms). mstockstill on DSK3G9T082PROD with RULES BILLING CODE 4910–13–C AD, do the actions specified in paragraphs When a statement identical to that in figure (k) AFM Revisions for Airplanes With (k)(1) and (k)(2) of this AD. 4 to paragraph (k)(1) of this AD has been Boeing Auxiliary Fuel Tanks (1) Revise Section 1 of the Limitations included in the general revisions of the section of the applicable Boeing 737 AFM to applicable Boeing 737 AFM, the general For airplanes with Boeing auxiliary fuel include the text specified in figure 4 to revisions may be inserted into the AFM, and tanks: Concurrently with accomplishment of paragraph (k)(1) of this AD.
