Airworthiness Directives; Airbus Helicopters Deutschland GmbH 
(AHD) Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: The FAA proposes to adopt a new airworthiness directive (AD) 
for all Airbus Helicopters Deutschland GmbH (AHD) Model EC135P1, 
EC135P2, EC135P2+, EC135P3, EC135T1, EC135T2, EC135T2+, EC135T3, MBB-BK 
117 C-2, MBB-BK 117 D-2, and MBB-BK 117 D-3 helicopters. This proposed 
AD was prompted by the determination that Instrument Flight Rules (IFR) 
screens obstruct the pilot's view. This proposed AD would require 
removing certain part-numbered IFR screens, as specified in a European 
Union Aviation Safety Agency (EASA) AD, which is proposed for 
incorporation by reference. This proposed AD would also prohibit 
installing those IFR screens on any helicopter. The FAA is proposing 
this AD to address the unsafe condition on these products.

and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this NPRM contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this NPRM, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this NPRM. Submissions containing CBI should be sent to Dan 
McCully, Aviation Safety Engineer, FAA, 1600 Stewart Avenue, Suite 410,

for this rulemaking.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2022-0097, dated June 1, 2022 (EASA 
AD 2022-0097), to correct an unsafe condition on Airbus Helicopters 
Deutschland GmbH Model EC135 P1, EC135 P2, EC135 P2+, EC135 P3, EC135 
T1, EC135 T2, EC135 T2+, EC135 T3, EC635 P2+, EC635 P3, EC635 T1, EC635 
T2+, EC635 T3, MBB-BK117 C-2, MBB-BK117 D-2, MBB-

[[Page 77537]]

BK117 D-3, and MBB-BK117 D-3m helicopters.
    This proposed AD was prompted by the determination that IFR screens 
obstruct the pilot's views. These IFR screens may be used for IFR 
training. According to Airbus Helicopters, the IFR screens obstruct the 
pilot's view to the front and to the right. The FAA is proposing this 
AD to address the obstructed views, which could lead to reduced 
situational awareness of the pilot and subsequent mid-air collision.
    You may examine EASA AD 2022-0097 in the AD docket at 
regulations.gov under Docket No. FAA-2023-2148.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0097 requires removing certain part-numbered IFR 
screens and prohibits installing them on any helicopter.
    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.

Other Related Service Information

    The FAA also reviewed Airbus Helicopters Alert Service Bulletin 
(ASB) EC135-25A-033, ASB EC135H-25A-007, ASB MBB-BK117 C-2-25A-022, and 
ASB MBB-BK117 D-2-25A-023, each Revision 0 and dated May 23, 2022, 
which specify procedures for removing the lower, pilot door, and upper 
IFR screens from the helicopter. This service information also 
specifies that the lower, pilot door, and upper IFR screens must not be 
installed on a helicopter and the respective maintenance manual task is 
invalid and must no longer be used.

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 the same type designs.

Proposed AD Requirements in This NPRM

    This proposed AD would require accomplishing the actions specified 
in EASA AD 2022-0097, described previously, as incorporated by 
reference, except for any differences identified as exceptions in the 
regulatory text of this proposed AD and except as discussed under 
``Differences Between this Proposed AD and the EASA 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 2022-0097 by reference in the FAA 
final rule. This proposed AD would, therefore, require compliance with 
EASA AD 2022-0097 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 2022-0097 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 2022-
0097. Service information referenced in EASA AD 2022-0097 for 
compliance will be available at regulations.gov under Docket No. FAA-
2023-2148 after the FAA final rule is published.

Differences Between This Proposed AD and the EASA AD

    EASA AD 2022-0097 applies to Model EC635 P2+, EC635 P3, EC635 T1, 
EC635 T2+, EC635 T3, and MBB-BK117 D-3m helicopters, whereas this 
proposed AD would not because those model helicopters are not FAA type-
certificated and are not included on the U.S. type certificate data 
sheet except where the U.S. type certificate data sheet explains that 
the Model EC635T2+ helicopter having serial number 0858 was converted 
from Model EC635T2+ to Model EC135T2+.

Costs of Compliance

    The FAA estimates that this AD, if adopted as proposed, would 
affect 573 helicopters of U.S. Registry. Labor rates are estimated at 
$85 per work-hour. Based on these numbers, the FAA estimates the 
following costs to comply with this proposed AD.
    Removing the IFR screens would take about 0.5 work-hour for an 
estimated cost of $43 per helicopter and up to $24,639 for the U.S. 
fleet.

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.
