SUPPLEMENTARY INFORMATION: Discussion On January 26, 2018, at 83 FR 3630, the Federal Register published our notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to Bell Model 212, Model 412, and Model 412EP helicopters with a certain EFS tube assembly installed. The NPRM proposed to require, within 300 hours time-in-service (TIS), replacing any EFS tube assembly part number (P/N) 412– 073–820–101 with an unknown manufacture date or that was manufactured before July 28, 2016. The NPRM also proposed to prohibit installing on any helicopter an EFS tube assembly P/N 412–073–820–101 that was manufactured before July 28, 2016 or that has an unknown manufacture date. The NPRM was prompted by a report from Bell that an EFS tube assembly separated from the valve during a 2-year inflation test. A subsequent investigation found that excessive sleeve preset force during manufacturing caused cracks in the sleeve of the tube assembly, which may result in the EFS float failing to deploy. Bell determined that only those EFS tube assemblies with P/N 412–073–820– 101 that were shipped prior to July 28, 2016, were subject to this manufacturing defect. Bell states that because this manufacturing defect is difficult to detect, affected EFS tube assemblies in service must be replaced. The affected parts were associated with a single Bell supplier that is no longer manufacturing the tube assembly. Comments amozie on DSK3GDR082PROD with RULES We gave the public the opportunity to participate in developing this AD, but we did not receive any comments on the NPRM. FAA’s Determination We have reviewed the relevant information and determined that an unsafe condition exists and is likely to exist or develop on other products of these same type designs and that air safety and the public interest require VerDate Sep<11>2014 16:35 Aug 29, 2018 Jkt 244001 adopting the AD requirements as proposed. Related Service Information We reviewed Bell Alert Service Bulletin (ASB) 212–11–143 for Bell Model 212 helicopters, and ASB 412– 11–147 for Bell Model 412 and 412EP helicopters, both Revision C and dated December 22, 2016. Each ASB describes and illustrates procedures to replace the tube assembly within 600 flight hours or by March 31, 2017. Differences Between This AD and the Service Information The service information requires compliance within 600 flight hours or by March 31, 2017; this AD requires compliance within 300 hours TIS. Costs of Compliance We estimate that this AD will affect 250 helicopters of U.S. Registry. We estimate that operators will incur the following costs in order to comply with this AD. At an average labor rate of $85 per hour, replacing a tube assembly will require about 6 workhours and required parts will cost $4,902, for a total cost of $5,412 per helicopter and $1,353,000 for the U.S. fleet. According to Bell’s service information, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage by Bell. 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. PO 00000 Frm 00036 Fmt 4700 Sfmt 4700 Regulatory Findings 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 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 AD and placed it in the AD docket.

The NPRM published in the Federal Register on April 27, 2018 (83 FR 18485). The NPRM was prompted by a revision of an airworthiness limitations document that specifies more restrictive maintenance requirements and airworthiness limitations. The NPRM proposed to require revising the maintenance or inspection program, as applicable, to incorporate revised fuel airworthiness limitations. We are issuing this AD to address the potential of ignition sources inside fuel tanks, which, in combination with flammable fuel vapors, could result in a fuel tank explosion and consequent loss of the airplane. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017–0169, dated September 7, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus SAS Model A318, A319, and A320 series airplanes; and Model A321–111, –112, –131, –211, –212, –213, –231, –232, –251N, –253N, and –271N airplanes. The MCAI states: The Fuel Airworthiness Limitations (FAL) for Airbus A320 family aeroplanes, which are approved by EASA, are currently defined and published in the Airbus A318/A319/A320/ A321 Airworthiness Limitations Section (ALS) Part 5 document. These instructions have been identified as mandatory for continued airworthiness. Failure to accomplish these instructions could result in a fuel tank explosion and consequent loss of the aeroplane.

SUPPLEMENTARY INFORMATION:

Discussion

    On January 26, 2018, at 83 FR 3630, the Federal Register published 
our notice of proposed rulemaking (NPRM), which proposed to amend 14 
CFR part 39 by adding an AD that would apply to Bell Model 212, Model 
412, and Model 412EP helicopters with a certain EFS tube assembly 
installed. The NPRM proposed to require, within 300 hours time-in-
service (TIS), replacing any EFS tube assembly part number (P/N) 412-
073-820-101 with an unknown manufacture date or that was manufactured 
before July 28, 2016. The NPRM also proposed to prohibit installing on 
any helicopter an EFS tube assembly P/N 412-073-820-101 that was 
manufactured before July 28, 2016 or that has an unknown manufacture 
date.
    The NPRM was prompted by a report from Bell that an EFS tube 
assembly separated from the valve during a 2-year inflation test. A 
subsequent investigation found that excessive sleeve preset force 
during manufacturing caused cracks in the sleeve of the tube assembly, 
which may result in the EFS float failing to deploy. Bell determined 
that only those EFS tube assemblies with P/N 412-073-820-101 that were 
shipped prior to July 28, 2016, were subject to this manufacturing 
defect. Bell states that because this manufacturing defect is difficult 
to detect, affected EFS tube assemblies in service must be replaced. 
The affected parts were associated with a single Bell supplier that is 
no longer manufacturing the tube assembly.

Comments

    We gave the public the opportunity to participate in developing 
this AD, but we did not receive any comments on the NPRM.

FAA's Determination

    We have reviewed the relevant information and determined that an 
unsafe condition exists and is likely to exist or develop on other 
products of these same type designs and that air safety and the public 
interest require adopting the AD requirements as proposed.

Related Service Information

    We reviewed Bell Alert Service Bulletin (ASB) 212-11-143 for Bell 
Model 212 helicopters, and ASB 412-11-147 for Bell Model 412 and 412EP 
helicopters, both Revision C and dated December 22, 2016. Each ASB 
describes and illustrates procedures to replace the tube assembly 
within 600 flight hours or by March 31, 2017.

Differences Between This AD and the Service Information

    The service information requires compliance within 600 flight hours 
or by March 31, 2017; this AD requires compliance within 300 hours TIS.

Costs of Compliance

    We estimate that this AD will affect 250 helicopters of U.S. 
Registry.
    We estimate that operators will incur the following costs in order 
to comply with this AD. At an average labor rate of $85 per hour, 
replacing a tube assembly will require about 6 work-hours and required 
parts will cost $4,902, for a total cost of $5,412 per helicopter and 
$1,353,000 for the U.S. fleet.
    According to Bell's service information, some of the costs of this 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage by Bell. 
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

    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 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 AD and placed it in the AD docket.
