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 all 
The Boeing Company Model DC-10-10 and DC-10-10F airplanes, Model DC-10-
15 airplanes, Model DC-10-30 and DC-10-30F (KC-10A and KDC-10) 
airplanes, Model DC-10-40 and DC-10-40F airplanes, Model MD-10-10F and 
MD-10-30F airplanes, and Model MD-11 and MD-11F airplanes. This 
proposed AD was prompted by results from fuel system reviews conducted 
by the manufacturer and multiple reports of fuel pump housing 
electrical connector failures related to ingress of airplane fluids. 
This proposed AD would require replacement of the fuel pump housing 
electrical connector or replacement of the fuel pump housing; 
repetitive inspections for proper operation and corrective actions if 
necessary; and revising the maintenance or inspection program to 
incorporate new airworthiness limitations. This proposed AD would also 
require, for certain airplanes, a general visual inspection of the 
protective cap and replacement if necessary. We are proposing this AD 
to prevent failure of the fuel pump housing electrical connector, which 
could result in a potential ignition source in a fuel tank and 
consequent fire or explosion.

DATES: We must receive comments on this proposed AD by June 24, 2016.

Discussion

    The FAA has examined the underlying safety issues involved in fuel 
tank explosions on several large transport airplanes, including the 
adequacy of existing regulations, the service history of airplanes 
subject to those regulations, and existing maintenance practices for 
fuel tank systems. As a result of those findings, we issued a 
regulation titled ``Transport Airplane Fuel Tank System Design Review, 
Flammability Reduction and Maintenance and Inspection Requirements'' 
(66 FR 23086, May 7, 2001). In addition to new airworthiness standards 
for transport airplanes and new maintenance requirements, this rule 
included Special Federal Aviation Regulation No. 88 (``SFAR 88,'' 
Amendment 21-78, and subsequent Amendments 21-82 and 21-83).
    Among other actions, SFAR 88 requires certain type design (i.e., 
type certificate (TC) and supplemental type certificate (STC)) holders 
to substantiate that their fuel tank systems can prevent ignition 
sources in the fuel tanks. This requirement applies to type design 
holders for large turbine-powered transport airplanes and for 
subsequent modifications to those airplanes. It requires them to 
perform design reviews and to develop design changes and maintenance 
procedures if their designs do not meet the new fuel tank safety 
standards. As explained in the preamble to the rule, we intended to 
adopt airworthiness directives to mandate any changes found necessary 
to address unsafe conditions identified as a result of these reviews.
    In evaluating these design reviews, we have established four 
criteria intended to define the unsafe conditions associated with fuel 
tank systems that require corrective actions. The percentage of 
operating time during which fuel tanks are exposed to flammable 
conditions is one of these criteria. The other three criteria address 
the failure types under evaluation: single failures, combination of 
failures, and unacceptable (failure) experience. For all three failure 
criteria, the evaluations included consideration of previous actions 
taken that may mitigate the need for further action.
    We have determined that the actions identified in this AD are 
necessary to reduce the potential of ignition sources inside fuel 
tanks, which, in combination with flammable fuel vapors, could result 
in fuel tank explosions and consequent loss of the airplane.
    We have received multiple reports of fuel pump housing electrical 
connector failures related to ingress of airplane fluids. Currently 
installed fuel pump housing electrical connectors have 18 month 
repetitive inspection requirements related to AD 2011-11-05, Amendment 
39-16704 (76 FR 31462, dated June 1, 2011) (``AD 2011-11-05''), and AD 
2002-13-10, Amendment 39-12798 (67 FR 45053, dated July 8, 2002) (``AD 
2002-13-10''). An improved fuel pump housing electrical connector has 
been developed to supersede the currently installed fuel pump housing 
electrical connector. Additionally, a secondary option has been 
developed that allows the operator to replace the fuel pump housing. In 
addition to the new fuel pump housing electrical connector, the use of 
environmentally sealed terminal lugs will help to prevent the wicking 
of airplane fluids into the fuel pump wires and the fuel pump housing 
electrical connector. This condition, if not corrected, could result in 
failure of the fuel pump housing electrical connector, causing a 
potential ignition source in a fuel tank and consequent fire or 
explosion.

Other Relevant Rulemaking

    AD 2000-22-21, Amendment 39-11969 (65 FR 69658, dated November 20, 
2000) (``AD 2000-22-21''), applies to all The Boeing Company Model DC-
10, Model MD-10, and Model MD-11 series airplanes. AD 2000-22-21 
requires revising the Airplane Flight Manual (AFM) to ensure that the 
flight crew is advised of appropriate procedures for disabling certain 
fuel pump electrical circuits following failure of a fuel pump 
electrical connector. For certain airplanes, AD 2000-22-21 also 
requires revising the AFM to prohibit resetting of tripped fuel pump 
circuit breakers. AD 2000-22-21 was prompted by reports of four 
incidents on McDonnell Douglas Model DC-10 and MD-11 series airplanes, 
in which a short circuit occurred in the electrical connector between 
the power lead and the housing of a fuel pump. The circuit breaker did 
not trip in any of these incidents because the electrical arcing that 
occurred was shorter in duration than necessary for the circuit breaker 
to detect the arcing and open the circuit. We issued AD 2000-22-21 to 
prevent continued arcing following a short circuit of the fuel pump 
electrical connector, which could damage the conduit that protects the 
power lead inside the fuel tank, and result in the creation of a 
potential ignition source in the fuel tank.
    AD 2002-13-10 applies to certain The Boeing Company Model DC-10-10, 
-10F, -15, -30, -30F, -30F (KC-10A and KDC-10), -40, and -40F 
airplanes; Model MD-10-10F and -30F airplanes; and Model MD-11 and -11F 
airplanes. AD 2002-13-10 requires repetitive tests for electrical 
continuity and resistance and repetitive inspections to detect 
discrepancies of the fuel boost/transfer pump connectors; and 
corrective actions, if necessary. AD 2002-13-10 was prompted by reports 
of five instances of failed connectors in the fuel boost/transfer pump 
circuit on The Boeing Company Model DC-10 and MD-11 series airplanes. 
We issued AD 2002-13-10 to prevent arcing of connectors in the fuel 
boost/transfer pump circuit, which could result in a fire or explosion 
of the fuel tank.
    AD 2003-07-14, Amendment 39-13110 (68 FR 17544, dated April 10, 
2003), applies to a single The Boeing Company Model DC-10-30 airplane. 
AD 2003-07-14 requires repetitive tests for electrical continuity and 
resistance and repetitive inspections to detect discrepancies of the 
fuel boost/transfer pump connectors; and corrective actions, if 
necessary. AD 2003-07-14 was prompted by reports of five instances of 
failed connectors in the fuel boost/transfer pump circuit on certain 
McDonnell Douglas Model DC-10 and MD-11 series airplanes. We issued AD 
2003-07-14 to prevent arcing of connectors in the fuel boost/transfer 
pump circuit, which could result in a fire or explosion of the fuel 
tank.
    AD 2008-06-21 R1, Amendment 39-16100 (74 FR 61504, November 25, 
2009), applies to all McDonnell Douglas Corporation Model DC-10-10 and 
DC-10-10F airplanes, Model DC-10-15 airplanes, Model DC-10-30 and DC-
10-30F (KC-10A and KDC-10) airplanes, Model DC-10-40 and DC-10-40F 
airplanes, Model MD-10-10F and MD-10-30F airplanes, and Model MD-11 and 
MD-11F airplanes. AD 2008-06-21 R1 requires revising the FAA-approved 
maintenance program, or the Airworthiness Limitations (AWLs) section of 
the Instructions for Continued Airworthiness, as applicable, to 
incorporate new AWLs for fuel tank systems to satisfy Special Federal 
Aviation Regulation No. 88 requirements. For certain airplanes, AD 
2008-06-21 R1 also requires the initial accomplishment of a certain 
repetitive AWL inspection to phase in that inspection, and repair if 
necessary. AD 2008-06-21 R1 clarifies the intended effect of the AD on 
spare and on-airplane fuel tank system components. AD 2008-06-21 R1 was 
prompted by a design review of the fuel tank system. We issued AD 2008-
06-21 R1 to prevent the potential for ignition sources inside fuel 
tanks caused by latent failures, alterations, repairs, or maintenance 
actions, which, in combination with flammable fuel vapors, could result 
in a fuel tank explosion and consequent loss of the airplane.
    AD 2011-11-05 applies to all The Boeing Company Model DC-10-10, DC-
10-10F, DC-10-15, DC-10-30, DC-10-30F (KC-10A and KDC-10), DC-10-40, 
DC-10-40F; Model MD-10-10F, MD-10-30F, MD-11, and MD-11F airplanes. AD 
2011-11-05 requires replacing the fuel pump housing electrical 
connector assembly with a new part and doing repetitive inspections for 
continuity, resistance, and insulation resistance, and doing corrective 
actions if necessary. AD 2011-11-05 was prompted by reports of failures 
of a certain fuel pump housing electrical connector. We issued AD 2011-
11-05 to detect and correct insulation resistance degradation and 
arcing in the potted backside of the electrical connector assembly of 
the fuel boost/transfer pump housing, which could compromise its 
performance and cause an ignition source in the fuel tank, resulting in 
a fuel tank explosion and consequent loss of the airplane.

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 these same type 
designs.

Proposed AD Requirements

    This proposed AD would require replacement of the fuel pump housing 
electrical connector or replacement of the fuel pump housing. This 
proposed AD would also require, for certain airplanes, a general visual 
inspection of the protective cap and replacement if necessary. This 
proposed AD would also require repetitive inspections for proper 
operation of the fuel pump and corrective actions if necessary. This 
proposed AD would also require revising the maintenance or inspection 
program to incorporate new airworthiness limitations.
    This proposed AD requires revisions to certain operator maintenance 
documents to include new actions (e.g., inspections) and CDCCLs. 
Compliance with these actions and CDCCLs is required by 14 CFR 
91.403(c). For airplanes that have been previously modified, altered, 
or repaired in the areas addressed by this AD, the operator may not be 
able to accomplish the actions described in the revisions. In this 
situation, to comply with 14 CFR 91.403(c), the operator must request 
approval for an alternative method of compliance according to paragraph 
(l) of this AD. The request should include a description of changes to 
the required inspections that will ensure the continued operational 
safety of the airplane.
    Notwithstanding any other maintenance or operational requirements, 
components that have been identified as airworthy or installed on the 
affected airplanes before accomplishing the revision of the airplane 
maintenance or inspection program specified in this proposed AD, do not 
need to be reworked in accordance with the CDCCLs. However, once the 
airplane maintenance or inspection program has been revised as required 
by this proposed AD, future maintenance actions on these components 
must be done in accordance with the CDCCLs.

[[Page 28773]]

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

Costs of Compliance

    We estimate that this proposed AD affects 246 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

cost estimates for the on-condition replacement and corrective actions 
specified in this proposed 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.

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.

    (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 (m)(1) of this AD. 
Information may be emailed to: 9-ANM-LAACO-AMOC-Requests@faa.gov.
    (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.

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.
