Airworthiness Directives; The Boeing Company Airplanes, 38982-38983 [2016-14111]

Download as PDF 38982 Federal Register / Vol. 81, No. 115 / Wednesday, June 15, 2016 / Proposed Rules period. A4A stated that the NPRMs are controversial and could drive substantial costs, especially for cargo airlines. To be able to prepare informed and meaningful comments with coordinated consensus among its members, A4A requested a longer comment period to understand a number of factors, including related service information, data and safety analysis of the unsafe condition, and potential costs. We agree with the request, and have determined that it is appropriate to extend the comment period for the NPRM to give all interested persons additional time to examine the proposed requirements and submit comments. We have determined that extending the comment period until September 19, 2016, will not compromise the safety of the affected airplanes. The comment period for Docket No. FAA–2016–6145 closes September 19, 2016. Because no other portion of the proposal or other regulatory information has been changed, the entire proposal is not being republished. Issued in Renton, Washington, on June 8, 2016.

We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion We issued an NPRM to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 767 airplanes. The NPRM published in the Federal Register on May 4, 2016 (81 FR 26747) (‘‘the NPRM’’). The NPRM proposed to require modifying the fuel quantity indicating system (FQIS) to prevent development of an ignition source inside the center fuel tank due to electrical fault conditions. The NPRM invited comments on regulatory, economic, environmental, and energy aspects of the proposal. The NPRM was prompted by fuel system reviews conducted by the manufacturer. The actions specified by the NPRM are intended to prevent ignition sources inside the center fuel tank, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. Related Rulemaking At the time we issued the NPRM, we issued five other NPRMs that also proposed to require modification of the FQIS: • Docket No. FAA–2016–6139, Directorate Identifier 2015–NM–061– AD, for certain The Boeing Company Model 737–600, –700, –700C, –800, –900, and –900ER series airplanes. • Docket No. FAA–2016–6140, Directorate Identifier 2015–NM–059– AD, for certain The Boeing Company Model 777 airplanes. • Docket No. FAA–2016–6143, Directorate Identifier 2015–NM–028– AD, for all Airbus Model A300 B4–600, B4–600R, and F4–600R series airplanes, and Model A300 C4–605R Variant F airplanes (collectively called Model A300–600 series airplanes), and Model A310 series airplanes. • Docket No. FAA–2016–6144, Directorate Identifier 2015–NM–088– AD, for Airbus Model A318, A319, A320, and A321 airplanes. • Docket No. FAA–2016–6145, Directorate Identifier 2015–NM–056– AD, for certain The Boeing Company Model 747 airplanes. Actions Since Previous NPRM Was Issued Since we issued the NPRM, we have received a request from Airlines for E:\FR\FM\15JNP1.SGM 15JNP1 Federal Register / Vol. 81, No. 115 / Wednesday, June 15, 2016 / Proposed Rules America (A4A) to withdraw the NPRM because of a specific concern regarding a yet-unpublished service bulletin. A4A stated that this service bulletin, which would add measures regarding removal of Kapton insulated wiring near the FQIS bundles, has been rejected by the FAA. A4A stated that there may be substantial changes to the proposed cost estimates that would influence the comments. A4A accordingly requested withdrawal of the NPRM until Boeing satisfies the FAA’s concerns, and the costs of compliance can be estimated. A4A asserted that any delay will not substantially affect safety given the previously instituted flammability reduction measures that are already in place. We disagree with the request to withdraw the NPRM. The FAA is currently reviewing service information related to Kapton wiring that may be installed near FQIS wires. The cost to remove existing Kapton wiring was not included in the NPRM for Model 767 airplanes; we do not anticipate that this cost will be significant. While we do not agree to withdraw the NPRM, we have determined that it is appropriate to extend the comment period for the NPRM to give all interested persons additional time to examine the proposed requirements and submit comments. We have determined that extending the comment period until September 19, 2016, will not compromise the safety of the affected airplanes.

Discussion

    We issued an NPRM to amend 14 CFR part 39 by adding an AD that 
would apply to certain The Boeing Company Model 767 airplanes. The NPRM 
published in the Federal Register on May 4, 2016 (81 FR 26747) (``the 
NPRM''). The NPRM proposed to require modifying the fuel quantity 
indicating system (FQIS) to prevent development of an ignition source 
inside the center fuel tank due to electrical fault conditions.
    The NPRM invited comments on regulatory, economic, environmental, 
and energy aspects of the proposal.
    The NPRM was prompted by fuel system reviews conducted by the 
manufacturer. The actions specified by the NPRM are intended to prevent 
ignition sources inside the center fuel tank, which, in combination 
with flammable fuel vapors, could result in a fuel tank explosion and 
consequent loss of the airplane.

Related Rulemaking

    At the time we issued the NPRM, we issued five other NPRMs that 
also proposed to require modification of the FQIS:
     Docket No. FAA-2016-6139, Directorate Identifier 2015-NM-
061-AD, for certain The Boeing Company Model 737-600, -700, -700C, -
800, -900, and -900ER series airplanes.
     Docket No. FAA-2016-6140, Directorate Identifier 2015-NM-
059-AD, for certain The Boeing Company Model 777 airplanes.
     Docket No. FAA-2016-6143, Directorate Identifier 2015-NM-
028-AD, for all Airbus Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model A300 C4-605R Variant F airplanes (collectively 
called Model A300-600 series airplanes), and Model A310 series 
airplanes.
     Docket No. FAA-2016-6144, Directorate Identifier 2015-NM-
088-AD, for Airbus Model A318, A319, A320, and A321 airplanes.
     Docket No. FAA-2016-6145, Directorate Identifier 2015-NM-
056-AD, for certain The Boeing Company Model 747 airplanes.

Actions Since Previous NPRM Was Issued

    Since we issued the NPRM, we have received a request from Airlines 
for

[[Page 38983]]

America (A4A) to withdraw the NPRM because of a specific concern 
regarding a yet-unpublished service bulletin. A4A stated that this 
service bulletin, which would add measures regarding removal of Kapton 
insulated wiring near the FQIS bundles, has been rejected by the FAA. 
A4A stated that there may be substantial changes to the proposed cost 
estimates that would influence the comments. A4A accordingly requested 
withdrawal of the NPRM until Boeing satisfies the FAA's concerns, and 
the costs of compliance can be estimated. A4A asserted that any delay 
will not substantially affect safety given the previously instituted 
flammability reduction measures that are already in place.
    We disagree with the request to withdraw the NPRM. The FAA is 
currently reviewing service information related to Kapton wiring that 
may be installed near FQIS wires. The cost to remove existing Kapton 
wiring was not included in the NPRM for Model 767 airplanes; we do not 
anticipate that this cost will be significant.
    While we do not agree to withdraw the NPRM, we have determined that 
it is appropriate to extend the comment period for the NPRM to give all 
interested persons additional time to examine the proposed requirements 
and submit comments. We have determined that extending the comment 
period until September 19, 2016, will not compromise the safety of the 
affected airplanes.
    The comment period for Docket No. FAA-2016-6141 closes September 
19, 2016.
    Because no other portion of the proposal or other regulatory 
information has been changed, the entire proposal is not being 
republished.
