Discussion

    On April 13, 2016, EASA, which is the Technical Agent for the 
Member States of the European Union, issued EASA Emergency AD No. 2016-
0073-E (AD 2016-0073-E) to correct an unsafe condition for Airbus 
Helicopters Model SA341G and SA342J helicopters with a crosstube part 
number (P/N) 341A415201.00 or P/N 341A415201.01. EASA advises that two 
reported failures of a crosstube have occurred during maintenance and 
towing operations, resulting in the helicopters dropping or tipping 
over. EASA further states that excessive hardness of the crosstube 
material, combined with inter-granular corrosion initiation, may have 
affected the structural integrity of the crosstube. EASA advises that 
this condition could lead to failure of the crosstube and dropping or 
tipping over of the helicopter. To address this unsafe condition, EASA 
AD 2016-0073-E requires identifying the affected crosstubes, 
implementing a temporary prohibition of autorotation training flights 
on affected helicopters by amending the RFM and installing a placard, 
inspecting the hardness of each affected crosstube, and replacing any 
crosstubes that do not meet the hardness criteria.

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 
the EASA AD. We are issuing this AD because we evaluated all 
information provided by EASA and determined the unsafe condition exists 
and is likely to

[[Page 67905]]

exist or develop on other helicopters of these same type designs.

Related Service Information Under 1 CFR Part 51

    Airbus Helicopters has issued Alert Service Bulletin (ASB) No. 
SA341/2-32.08, Revision 0, dated March 24, 2016 (ASB 32.08), which 
specifies removing the crosstube, checking its hardness, and replacing 
the crosstube if it fails the hardness test. ASB 32.08 also specifies 
prohibiting autorotation training flights by installing a placard on 
the instrument panel.
    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 Aerospatiale (now Airbus Helicopters) Flight 
Manuals SA 341G, Issue 2, dated December 1974, and SA 342J, Issue 1, 
dated April 27, 1976. These manuals provide various procedures, 
limitations, and performance and loading information.

AD Requirements

    This AD requires, before further flight, prohibiting autorotation 
training flights by amending the RFM and installing a limitation 
placard on the instrument panel.
    This AD also requires, within 25 hours time-in-service (TIS), 
applying a solution to the crosstube to determine whether the metal is 
coated and removing all coating within a specific area. Once there is 
no coating, this AD requires inspecting the hardness of the crosstube 
and replacing the crosstube if it does not meet the hardness criteria. 
After determining the crosstube meets the hardness criteria, the 
placard and RFM amendment prohibiting autorotation training flights may 
be removed.

Differences Between This AD and the EASA AD

    EASA requires the hardness inspection to be completed within six 
months, while we require the hardness inspection to be completed within 
25 hours TIS.

Costs of Compliance

    We estimate that this AD affects 17 helicopters of U.S. Registry.
    We estimate that operators may incur the following costs in order 
to comply with this AD. At an average labor rate of $85 per hour, 
amending the RFM and installing a placard will require about 0.5 work-
hour, for a cost per helicopter of $43, and a total cost of $731 to the 
U.S. fleet. Inspecting a crosstube will require about 8 work-hours, and 
the required materials cost is minimal, for a cost per helicopter of 
$680 and a total cost of $11,560 to the U.S. fleet.
    If required, replacing a crosstube will require 8 work-hours, and 
required parts will cost $11,952, for a total cost of $12,632 per 
helicopter.

FAA's Justification and Determination of the Effective Date

    Providing an opportunity for public comments prior to adopting 
these AD requirements would delay implementing the safety actions 
needed to correct this known unsafe condition. Therefore, we find that 
the risk to the flying public justifies waiving notice and comment 
prior to the adoption of this rule because certain operations must be 
prohibited before further flight until the required corrective actions 
are accomplished. Those corrective actions must then be accomplished 
within 25 hours TIS, a short time interval for these model helicopters.
    Since an unsafe condition exists that requires the immediate 
adoption of this AD, we determined that notice and opportunity for 
public comment before issuing this AD are impracticable and that good 
cause exists for making this amendment effective in less than 30 days.

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 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, 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.
