Abstract
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Helicopters Deutschland GmbH Model MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters. This proposed AD was prompted by report that a collective bellcrank-K was found incorrectly installed on a helicopter. This proposed AD would require inspecting the collective bellcrank-K to determine if it is correctly installed and has a correct position marking and, depending on the findings, applicable corrective actions, as specified in a European Union Aviation Safety Agency (EASA) AD, which is proposed for incorporation by reference (IBR). This proposed AD would also allow installation of an affected collective bellcrank-K, provided certain instructions are followed. The FAA is proposing this AD to address the unsafe condition on these products.

Background
EASA, which is the Technical Agent for the Member States of the
European Union, has issued EASA AD 2021-0074, dated March 15, 2021
(EASA AD 2021-0074), to correct an unsafe condition for all Airbus
Helicopters Deutschland GmbH (formerly Eurocopter Deutschland GmbH; and
Airbus Helicopters Inc., formerly American Eurocopter LLC) Model MBB-
BK117 C-2 and MBB-BK117 D-2 helicopters.
This proposed AD was prompted by a report that a collective
bellcrank-K (affected part) was found incorrectly installed on a
helicopter. Subsequent investigations revealed that the affected part
was an in-service replacement, and that the position marking on that
part was incorrect. The FAA is proposing this AD to address incorrect
installation of a collective bellcrank-K, which could lead to unwanted
collective input, resulting in reduced control of the helicopter. See
EASA AD 2021-0074 for additional background information.
Related Service Information Under 1 CFR Part 51
EASA AD 2021-0074 requires a one-time inspection of an affected
part for correct installation by measuring the distance between the
front edge of the bearing block and the front edge of the affected
part, and for correct application of position markings, and, depending
on the findings, accomplishment of applicable corrective actions. If an
affected part is incorrectly installed, the corrective actions include
inspecting for signs of chafing on the bearing block, the control
lever, the forked lever, the sliding sleeve, and the bearing ring,
replacing any parts that have signs of chafing, and installing a
serviceable bellcrank-K with an applied position marking. If an
affected part is correctly installed but the position marking is not
correct, the corrective actions include re-working the affected part or
replacing the affected part with a serviceable part that has an applied
position marking. EASA AD 2021-0074 also allows installation of an
affected part, provided certain instructions are followed.
This material 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.
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 about the
unsafe condition described in its AD. The FAA is proposing this AD
after evaluating all known relevant information and determining that
the unsafe condition described previously is likely to exist or develop
on other helicopters of these same type designs.
Proposed AD Requirements in This NPRM
This proposed AD would require accomplishing the actions specified
in EASA AD 2021-0074, described previously, as incorporated by
reference, except for any differences identified as exceptions in the
regulatory text of this proposed AD.
Explanation of Required Compliance Information
In the FAA's ongoing efforts to improve the efficiency of the AD
process, the FAA developed a process to use some civil aviation
authority (CAA) ADs as the primary source of information for compliance
with requirements for corresponding FAA ADs. The FAA has been
coordinating this process with manufacturers and CAAs. As a result, the
FAA proposes to incorporate EASA AD 2021-0074 by reference in the FAA
final rule. This proposed AD would, therefore, require compliance with
EASA AD 2021-0074 in its entirety through that incorporation, except
for any differences identified as exceptions in the regulatory text of
this proposed AD. Using common terms that are the same as the heading
of a particular section in EASA AD 2021-0074 does not mean that
operators need comply only with that section. For example, where the AD
requirement refers to ``all required actions and compliance times,''
compliance with this AD requirement is not limited to the section
titled ``Required Action(s) and Compliance Time(s)'' in EASA AD 2021-
0074. Service information required by EASA AD 2021-0074 for compliance
will be available at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and
locating Docket No. FAA-2021-1007 after the FAA final rule is
published.
Costs of Compliance
The FAA estimates that this AD, if adopted as proposed, would
affect 140 helicopters of U.S. Registry. The FAA estimates the
following costs to comply with this proposed AD.
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Inspection for correct installation 0.50 work-hour x $85 per $0 $42.50 $5,950
and position marking. hour = $42.50.
----------------------------------------------------------------------------------------------------------------
[[Page 67366]]
The FAA estimates the following costs to do any necessary
replacements or rework that would be required based on the results of
the proposed inspection. The agency has no way of determining the
number of helicopters that might need this replacement or rework:
On-Condition Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Replace collective bellcrank-K................ 8 work-hours x $85 per hour = $4,018 $4,698
$680.
Rework collective bellcrank-K................. 2 work-hours x $85 per hour = 0 170
$170.
----------------------------------------------------------------------------------------------------------------
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 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 above, I certify this proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Would not affect intrastate aviation in Alaska, and
(3) Would not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new airworthiness
directive:
Airbus Helicopters Deutschland GmbH: Docket No. FAA-2021-1007;
Project Identifier MCAI-2021-00324-R.
(a) Comments Due Date
The FAA must receive comments on this airworthiness directive
(AD) by January 10, 2022.
(b) Affected ADs
None.
(c) Applicability
This AD applies to all Airbus Helicopters Deutschland GmbH Model
MBB-BK 117 C-2 and MBB-BK 117 D-2 helicopters, certificated in any
category.
(d) Subject
Joint Aircraft Service Component (JASC) Code: 6230, Main Rotor
Mast/Swashplate.
(e) Unsafe Condition
This AD was prompted a report that a collective bellcrank-K
(affected part) was found incorrectly installed on a helicopter.
Subsequent investigations found that the affected part was an in-
service replacement, and that the position marking on that part was
incorrect. The FAA is issuing this AD to incorrect installation of a
collective bellcrank-K, which could lead to unwanted collective
input, resulting in reduced control of the helicopter.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Requirements
Except as specified in paragraph (h) of this AD: Comply with all
required actions and compliance times specified in, and in
accordance with, European Union Aviation Safety Agency (EASA) AD
2021-0074, dated March 15, 2021 (EASA AD 2021-0074).
(h) Exceptions to EASA AD 2021-0074
(1) Where EASA AD 2021-0074 requires compliance in terms of
flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2021-0074 refers to its effective date, this
AD requires using the effective date of this AD.
(3) Where the service information referenced in EASA AD 2021-
0074 specifies discarding a part, this AD requires removing that
part from service.
(4) Where the service information referenced in EASA AD 2021-
0074 specifies contacting Airbus Helicopters for instructions to
rework a bellcrank-K, the rework must be accomplished using a method
approved by the Manager, General Aviation & Rotorcraft Section,
International Validation Branch, FAA; or EASA; or Airbus
Helicopters' EASA Design Organization Approval (DOA). If approved by
the DOA, the approval must include the DOA-authorized signature.
(5) Where the service information referenced in EASA AD 2021-
0074 specifies to ``forecast the compliance time of Part IV and
schedule the accomplishment accordingly,'' for clarification, this
AD requires doing the correction of the position marking of the
bellcrank-K at the time specified in paragraph (3) of EASA AD 2021-
0074.
(6) Where the service information referenced in EASA AD 2021-
0074 specifies contacting Airbus Helicopters if there is mechanical
damage or corrosion on the bushings of the bellcrank assembly, this
AD does not require that action.
(7) This AD does not mandate compliance with the ``Remarks''
section of EASA AD 2021-0074.
(i) No Reporting Requirement
Although the service information referenced in EASA AD 2021-0074
specifies to submit certain information to the manufacturer, this AD
does not include that requirement.
(j) Alternative Methods of Compliance (AMOCs)
(1) The Manager, International Validation Branch, FAA, has the
authority to approve AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19,
send your request to your principal inspector or local Flight
Standards District Office, as appropriate. If sending information
