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 EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD No. 2016– 0200, dated October 11, 2016 (AD 2016– 0200), to correct an unsafe condition for Airbus Helicopters Model EC 225 LP helicopters. EASA advises of a report of the left-hand and right-hand bellcranks becoming jammed. EASA states an investigation determined the bellcranks were jammed by the accumulation of a foreign coating material in the bellcrank hole. EASA further states that investigation of an additional incident of a jammed bellcrank determined that corrosion in the bellcrank hole caused the jam. This condition, according to EASA, could result in failure of the life rafts to release in an emergency and subsequent injury to occupants during an otherwise survivable accident. To address this, EASA AD 2016–0200 requires repetitive cleaning and lubrication of each bellcrank and pivot link. sradovich on DSK3GMQ082PROD with PROPOSALS FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, its technical representative, has notified us of the unsafe condition described in its AD. We are proposing this AD because we evaluated all known relevant information and determined that an unsafe condition is likely to exist or develop on other helicopters of the same type design. Related Service Information We reviewed Airbus Helicopters Emergency Alert Service Bulletin No. 05A050, Revision 0, dated July 22, 2016, which contains procedures for cleaning and lubricating each bellcrank and pivot link of the life raft inflation cylinder percussion system and removing any corrosion if necessary. VerDate Sep<11>2014 16:04 Aug 08, 2018 Jkt 244001 Proposed AD Requirements This proposed AD would require, before further flight and thereafter at intervals not exceeding 6 months, cleaning and lubricating each bellcrank and pivot link. Costs of Compliance We estimate that this proposed AD would affect 5 helicopters of U.S. Registry. At an average labor rate of $85 per work-hour, we estimate that operators may incur the following costs in order to comply with this AD. Cleaning and lubricating both bellcranks and pivot links would require about 16 workhours, and required materials costs would be minimal, for a cost of $1,360 per helicopter and $6,800 for the U.S. fleet per inspection cycle. 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 PO 00000 Frm 00008 Fmt 4702 Sfmt 4702 39383 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

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2016-0200, dated October 11, 
2016 (AD 2016-0200), to correct an unsafe condition for Airbus 
Helicopters Model EC 225 LP helicopters. EASA advises of a report of 
the left-hand and right-hand bellcranks becoming jammed. EASA states an 
investigation determined the bellcranks were jammed by the accumulation 
of a foreign coating material in the bellcrank hole. EASA further 
states that investigation of an additional incident of a jammed 
bellcrank determined that corrosion in the bellcrank hole caused the 
jam. This condition, according to EASA, could result in failure of the 
life rafts to release in an emergency and subsequent injury to 
occupants during an otherwise survivable accident. To address this, 
EASA AD 2016-0200 requires repetitive cleaning and lubrication of each 
bellcrank and pivot link.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
its AD. We are proposing this AD because we evaluated all known 
relevant information and determined that an unsafe condition is likely 
to exist or develop on other helicopters of the same type design.

Related Service Information

    We reviewed Airbus Helicopters Emergency Alert Service Bulletin No. 
05A050, Revision 0, dated July 22, 2016, which contains procedures for 
cleaning and lubricating each bellcrank and pivot link of the life raft 
inflation cylinder percussion system and removing any corrosion if 
necessary.

Proposed AD Requirements

    This proposed AD would require, before further flight and 
thereafter at intervals not exceeding 6 months, cleaning and 
lubricating each bellcrank and pivot link.

Costs of Compliance

    We estimate that this proposed AD would affect 5 helicopters of 
U.S. Registry.
    At an average labor rate of $85 per work-hour, we estimate that 
operators may incur the following costs in order to comply with this 
AD. Cleaning and lubricating both bellcranks and pivot links would 
require about 16 work-hours, and required materials costs would be 
minimal, for a cost of $1,360 per helicopter and $6,800 for the U.S. 
fleet per inspection cycle.

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
