We will file in the docket all comments that we receive, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, we will consider all comments we receive on or before the closing date for comments. We will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. We may change this proposal in light of the comments we receive. Discussion On August 13, 2015, we issued SAIB SW–15–20 to alert owners and operators of Bell Helicopter Textron Canada Limited (Bell) Model 206, 407, and 427; Agusta S.p.A. Model A119; and Airbus Helicopters Model AS350, EC120, and EC130 helicopters of possible overheated and melted connectors in the wiring of certain Air Comm air conditioning system units. SAIB SW– 15–20 was prompted by a report of a melted and discolored aft evaporator assembly connector due to poor crimping during installation of the connector or during production. SAIB SW–15–20 recommends inspecting the connecters for evidence of overheating and loose contact by following the Air Comm service bulletins, and if there is evidence of overheating or loose contact, making the air conditioning system inoperable until those connectors are replaced. Since we issued SAIB SW–15–20, we received additional reports of melted and burned connectors. Further investigation revealed the connector design may be insufficient for some of these model helicopters because of electrical current load, installation location, vibration environment, and susceptibility to environmental factors. As a result, the connector may develop low pin tension between the socket and the pin, leading to high electrical resistance, subsequently resulting in excessive pin and socket temperatures. Overheating of the connector could result in a fire and subsequent loss of control of the helicopter. In July 2016, Air Comm introduced a newly designed connector that can withstand the demands and environment of the aft evaporator blower motor. Accordingly, we are proposing an AD for certain part-numbered Air Comm air conditioning systems installed on Airbus Helicopters Model AS350B, PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 AS350B1, AS350B2, AS350B3, AS350BA, AS350C, AS350D, AS350D1, and EC130B4, and Bell Model 206A, 206B, 206L, 206L–1, 206L–3, and 206L– 4, and 407 helicopters. This proposed AD would require replacing each aft evaporator blower motor connector with the newly designed connector and would prohibit installing certain parts in the aft evaporator assembly, aft evaporator blower assembly, and aft condenser blower. The actions specified in this proposed AD are intended to prevent overheating of a connector, which could result in a fire and subsequent loss of control of the helicopter. These Air Comm air conditioning systems may be installed on Airbus Helicopters Model AS350B, AS350B1, AS350B2, AS350B3, AS350BA, AS350C, AS350D, and AS350D1 helicopters per Supplemental Type Certificate (STC) SR00643DE; on Airbus Helicopters Model EC130B4 helicopters per STC SR00543DE; on Bell Model 206A, 206B, 206L, 206L–1, 206L–3, and 206L–4 helicopters per STC SH2750NM; and on Bell Model 407 helicopters per STC SR00222DE. Because field reports revealed that Agusta S.p.A. Model A119, Airbus Helicopters Model EC120, and Bell Model 427 helicopters are not affected by this unsafe condition, we are not including these models in this proposed AD. FAA’s Determination We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition exists and is likely to exist or develop on other products of these same type designs. Related Service Information Under 1 CFR Part 51 We reviewed Air Comm Corporation Service Bulletin (SB) SB AS350–111014 for Airbus Helicopters AS350 series helicopters and SB EC130–6204 for Airbus Helicopters EC130 series helicopters, both Revision B and dated January 10, 2017. We also reviewed SB 206–110414 for Bell 206 series helicopters, Revision C, and SB 407– 110414 for Bell Model 407 helicopters, Revision D, both dated January 13, 2017. This service information specifies inspecting certain aft evaporator blower motor and certain condenser blower electrical connectors for indications of overheating, discoloration, and plastic deformation and performing a pull test. This service information also specifies replacing connector housings and contacts that fail the inspection or the pull test. E:\FR\FM\11JAP1.SGM 11JAP1 Federal Register / Vol. 83, No. 8 / Thursday, January 11, 2018 / Proposed Rules 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. Other Related Service Information We also reviewed the following Air Comm Corporation service information: • SB AS350–111014 and SB EC130– 6204, both Revision A and both dated July 6, 2016; • SB 206–110414, Revision B, dated January 10, 2017 and Revision A dated June 3, 2016; and • SB 407–110414, Revision C, dated January 10, 2017, and Revision B, dated July 6, 2016. This service information contains the same procedures described above. However, SB AS350–111014 and SB EC130–6204, both Revision B and dated January 10, 2017, contain additional instructions and figures for the connectors. SB 206–110414, Revision C, and SB 407–110414, Revision D, both dated January 13, 2017, contain minor corrections. Proposed AD Requirements This proposed AD would require replacing certain connectors with Air Comm connectors and prohibit installing certain part-numbered plugs, sockets, receptacles, and pin in certain part-numbered aft evaporator assemblies, aft evaporator blower assemblies, and aft condenser blowers. Differences Between This Proposed AD and the Service Information The Air Comm service information specifies a compliance time of 20 flight hours. This proposed AD would require compliance within 90 hours time-inservice. The Air Comm service information specifies inspecting each connector and replacing the connector housings and contacts that have any signs of overheating or that fail a pull test. This proposed AD would require replacing each connector without an inspection. This proposed AD would also prohibit installing certain parts in certain part-numbered aft evaporator assemblies, aft evaporator blower assemblies, and aft condenser blowers. sradovich on DSK3GMQ082PROD with PROPOSALS Costs of Compliance We estimate that this proposed AD would affect 914 units installed on helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Replacing the connectors would take about 1 work-hour and parts would cost about $60 for a total cost of VerDate Sep<11>2014 17:00 Jan 10, 2018 Jkt 244001 1315 $145 per helicopter and $132,530 for the U.S. fleet. According to Air Comm’s service information, 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 by Air Comm. Accordingly, we have included all costs in our cost estimate. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Authority for This Rulemaking PART 39—AIRWORTHINESS DIRECTIVES 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, 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 to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Discussion

    On August 13, 2015, we issued SAIB SW-15-20 to alert owners and 
operators of Bell Helicopter Textron Canada Limited (Bell) Model 206, 
407, and 427; Agusta S.p.A. Model A119; and Airbus Helicopters Model 
AS350, EC120, and EC130 helicopters of possible overheated and melted 
connectors in the wiring of certain Air Comm air conditioning system 
units. SAIB SW-15-20 was prompted by a report of a melted and 
discolored aft evaporator assembly connector due to poor crimping 
during installation of the connector or during production. SAIB SW-15-
20 recommends inspecting the connecters for evidence of overheating and 
loose contact by following the Air Comm service bulletins, and if there 
is evidence of overheating or loose contact, making the air 
conditioning system inoperable until those connectors are replaced.
    Since we issued SAIB SW-15-20, we received additional reports of 
melted and burned connectors. Further investigation revealed the 
connector design may be insufficient for some of these model 
helicopters because of electrical current load, installation location, 
vibration environment, and susceptibility to environmental factors. As 
a result, the connector may develop low pin tension between the socket 
and the pin, leading to high electrical resistance, subsequently 
resulting in excessive pin and socket temperatures. Overheating of the 
connector could result in a fire and subsequent loss of control of the 
helicopter. In July 2016, Air Comm introduced a newly designed 
connector that can withstand the demands and environment of the aft 
evaporator blower motor.
    Accordingly, we are proposing an AD for certain part-numbered Air 
Comm air conditioning systems installed on Airbus Helicopters Model 
AS350B, AS350B1, AS350B2, AS350B3, AS350BA, AS350C, AS350D, AS350D1, 
and EC130B4, and Bell Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-
4, and 407 helicopters. This proposed AD would require replacing each 
aft evaporator blower motor connector with the newly designed connector 
and would prohibit installing certain parts in the aft evaporator 
assembly, aft evaporator blower assembly, and aft condenser blower. The 
actions specified in this proposed AD are intended to prevent 
overheating of a connector, which could result in a fire and subsequent 
loss of control of the helicopter.
    These Air Comm air conditioning systems may be installed on Airbus 
Helicopters Model AS350B, AS350B1, AS350B2, AS350B3, AS350BA, AS350C, 
AS350D, and AS350D1 helicopters per Supplemental Type Certificate (STC) 
SR00643DE; on Airbus Helicopters Model EC130B4 helicopters per STC 
SR00543DE; on Bell Model 206A, 206B, 206L, 206L-1, 206L-3, and 206L-4 
helicopters per STC SH2750NM; and on Bell Model 407 helicopters per STC 
SR00222DE. Because field reports revealed that Agusta S.p.A. Model 
A119, Airbus Helicopters Model EC120, and Bell Model 427 helicopters 
are not affected by this unsafe condition, we are not including these 
models in this proposed AD.

FAA's Determination

    We are proposing this AD because we evaluated all known relevant 
information and determined that an unsafe condition exists and is 
likely to exist or develop on other products of these same type 
designs.

Related Service Information Under 1 CFR Part 51

    We reviewed Air Comm Corporation Service Bulletin (SB) SB AS350-
111014 for Airbus Helicopters AS350 series helicopters and SB EC130-
6204 for Airbus Helicopters EC130 series helicopters, both Revision B 
and dated January 10, 2017. We also reviewed SB 206-110414 for Bell 206 
series helicopters, Revision C, and SB 407-110414 for Bell Model 407 
helicopters, Revision D, both dated January 13, 2017. This service 
information specifies inspecting certain aft evaporator blower motor 
and certain condenser blower electrical connectors for indications of 
overheating, discoloration, and plastic deformation and performing a 
pull test. This service information also specifies replacing connector 
housings and contacts that fail the inspection or the pull test.

[[Page 1315]]

    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.

Other Related Service Information

    We also reviewed the following Air Comm Corporation service 
information:
     SB AS350-111014 and SB EC130-6204, both Revision A and 
both dated July 6, 2016;
     SB 206-110414, Revision B, dated January 10, 2017 and 
Revision A dated June 3, 2016; and
     SB 407-110414, Revision C, dated January 10, 2017, and 
Revision B, dated July 6, 2016.
    This service information contains the same procedures described 
above. However, SB AS350-111014 and SB EC130-6204, both Revision B and 
dated January 10, 2017, contain additional instructions and figures for 
the connectors. SB 206-110414, Revision C, and SB 407-110414, Revision 
D, both dated January 13, 2017, contain minor corrections.

Proposed AD Requirements

    This proposed AD would require replacing certain connectors with 
Air Comm connectors and prohibit installing certain part-numbered 
plugs, sockets, receptacles, and pin in certain part-numbered aft 
evaporator assemblies, aft evaporator blower assemblies, and aft 
condenser blowers.

Differences Between This Proposed AD and the Service Information

    The Air Comm service information specifies a compliance time of 20 
flight hours. This proposed AD would require compliance within 90 hours 
time-in-service. The Air Comm service information specifies inspecting 
each connector and replacing the connector housings and contacts that 
have any signs of overheating or that fail a pull test. This proposed 
AD would require replacing each connector without an inspection. This 
proposed AD would also prohibit installing certain parts in certain 
part-numbered aft evaporator assemblies, aft evaporator blower 
assemblies, and aft condenser blowers.

Costs of Compliance

    We estimate that this proposed AD would affect 914 units installed 
on helicopters of U.S. Registry. We estimate that operators may incur 
the following costs in order to comply with this AD. Labor costs are 
estimated at $85 per work-hour. Replacing the connectors would take 
about 1 work-hour and parts would cost about $60 for a total cost of 
$145 per helicopter and $132,530 for the U.S. fleet.
    According to Air Comm's service information, 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 by Air Comm. Accordingly, 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, 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, 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 to the extent that 
it justifies making a regulatory distinction; 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this proposed AD and placed it in the AD docket.
