Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD No. 2019-0184, dated July 29, 2019, 
to correct an unsafe condition for Airbus Helicopters (AH), formerly 
Eurocopter, Eurocopter France, Aerospatiale, Sud Aviation, Model SA 365 
N, SA 365 N1, AS 365 N2, AS 365 N3, EC155 B and EC155 B1 helicopters, 
AS 350 B3 helicopters if equipped with dual hydraulic system (OP 3346 
or OP 3082), EC 130 B4 and EC 130 T2 helicopters, and AS355 F, AS355 
F1, AS355 F2, AS355 N and AS355 NP helicopters. EASA advises that a 
Model AS 365 N3 helicopter experienced a sudden, strong nose-up 
attitude followed by intense vibrations and increased loads on the 
flight controls during a cruise flight. Following an emergency landing, 
the post-flight visual inspection of the front left-hand M/R servo 
actuator showed that the threaded-shouldered bushing holding the lower 
end-fitting was uncoupled from the actuator body. EASA further advises 
that other helicopter models are affected due design similarity of the 
installed M/R servo actuators. EASA also advises that this condition, 
if not detected and corrected, could lead to loss of control of the 
helicopter.
    Accordingly, the EASA AD requires a one-time inspection of each M/R 
servo actuator for correct installation and, depending on the findings, 
replacing the affected part or applying a slippage mark. The EASA AD 
also requires inspecting the slippage mark for misalignment and, 
depending on the findings replacing the affected part. EASA considers 
its AD an interim action and states that further AD action may follow.

FAA's Determination

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's bilateral 
agreement with the European Union, EASA has notified the FAA of the 
unsafe condition described in its AD. The FAA is issuing this AD after 
evaluating all of the information provided by EASA and determining the 
unsafe condition exists and is likely to exist or develop on other 
helicopters of the same type designs.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed one document that co-publishes eight Airbus 
Helicopters Emergency Alert Service Bulletin (EASB) identification 
numbers: No. 67.00.17 for Model AS365 N, N1, N2, and N3 helicopters and 
non FAA-type certificated military Model AS365 F, Fs, Fi, K, and K2 
helicopters; No. 67.00.10 for non FAA-type certificated military Model 
AS565 MA, MB, MBe, SA, SB, and UB helicopters; No. 67.11 for non FAA-
type certificated military Model SA366 GA helicopters; No. 67A016 for 
Model EC155 B and B1 helicopters; No. 67.00.77 for Model AS350 B3 
helicopters; No. 67.00.48 for Model AS355 F, F1, F2, N, and NP 
helicopters; No. 67.00.33 for non FAA-type certificated military Model 
AS555 AF, AN, AP, SN, UF, and UN helicopters; and No. 67A021 for Model 
EC130 B4 and T2 helicopters, each Revision 0 and dated July 25, 2019. 
EASB Nos. 67.00.17, 67A016, 67.00.77, 67.00.48, and 67A021 are 
incorporated by reference in this AD. EASB Nos. 67.00.10, 67.11, and 
67.00.33 are not incorporated by reference in this AD.
    This service information specifies procedures for inspecting the 
links between the lower ball end fitting and the M/R actuator rods. 
This service information also specifies procedures for applying a 
slippage mark (red mark) and inspecting the slippage mark.
    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.

AD Requirements

    This AD requires, within 30 hours time-in-service (TIS), with any 
sealing compound on the lower ball end fitting link removed, inspecting 
each M/R servo actuator for correct installation by inspecting the link 
between the lower ball end fitting and the actuator rod for visible 
threads and play between the actuator rod and the punched lockwasher, 
inspecting for protrusion of the threaded shouldered bushing from the 
punched lockwasher, and inspecting the alignment between the punching 
of the punched lockwasher and the stud of the lower ball end fitting. 
Depending on the inspection results, this AD requires replacing the M/R 
servo actuator and reporting the inspection results to Airbus 
Helicopters if there is any visible thread or play between the actuator 
rod and the punched lockwasher, protrusion of the threaded shouldered 
bushing, or misalignment between the punching of the punched lockwasher 
and the stud of the lower ball end fitting. This AD also requires 
applying a slippage mark from the actuator rod (excluding the chamfered 
part of the rod) to the nut, including the punched lockwasher and the 
lockwasher.

Differences Between This AD and the EASA AD

    The EASA AD is applicable to affected M/R servo actuators that were 
supplied by Airbus Helicopters before August 12, 2019, whereas this AD 
applies to affected M/R servo actuators that were manufactured before 
July 25, 2019 or with an unknown date of manufacture, instead. The EASA 
AD requires the one-time inspection within 55 flight hours, whereas 
this AD requires the one-time inspection within 30 hours TIS instead. 
The EASA AD requires a longer-term inspection of the slippage mark for 
misalignment for affected M/R servo actuators regardless of when they 
were originally supplied, whereas this AD does not. The FAA plans to 
publish a notice of proposed rulemaking to give the public an 
opportunity to comment on this longer-term requirement.

Interim Action

    The FAA considers this AD to be an interim action. If final action 
is later identified, the FAA might consider further rulemaking then.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because the FAA has determined 
that it has good cause to adopt this rule without notice and comment, 
RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 1,270 helicopters of U.S. 
Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates that operators may incur the following 
costs in order to comply with this AD.
    Inspecting the M/R servo actuators takes about one work-hour for an 
estimated cost of $85 per helicopter and

[[Page 63433]]

$107,950 for the U.S. fleet. Applying a slippage mark takes a minimal 
amount of time at a nominal cost.
    If required, reporting information takes about 1 hour for an 
estimated cost of $85.
    Replacing an M/R actuator takes about 2 work-hours and parts cost 
up to $53,315 for an estimated cost of up to $53,485 per replacement.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to a penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to be 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden to: Information Collection 
Clearance Officer, Federal Aviation Administration, 10101 Hillwood 
Parkway, Fort Worth, TX 76177-1524.

FAA's Justification and Determination of the Effective Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (5 U.S.C.) 
authorizes agencies to dispense with notice and comment procedures for 
rules when the agency, for ``good cause'' finds that those procedures 
are ``impracticable, unnecessary, or contrary to the public interest.'' 
Under this section, an agency, upon finding good cause, may issue a 
final rule without seeking comment prior to the rulemaking.
    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because the required corrective action must be completed within 30 
hours TIS, a time period of up to one month based on the average 
flight-hour utilization rate of these helicopters. Therefore, the FAA 
finds good cause that notice and opportunity for prior public comment 
are impracticable. In addition, for the reason(s) stated above, the FAA 
finds 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.
    The FAA is 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

    The FAA 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, and
    2. Will not affect intrastate aviation in Alaska.
