Abstract
The FAA is superseding Airworthiness Directive (AD) 2021-22-20 which applied to certain Austro Engine GmbH E4 and E4P model diesel piston engines. AD 2021-22-20 required, for engines with an affected cylinder head, inspection of the high pressure pump (HPP) driving gear and, depending on the results of the inspection, replacement of the HPP driving gear with a part eligible for installation. AD 2021-22-20 also required, for engines with an affected HPP driving gear, replacement of the HPP driving gear before further flight or within a certain number of flight hours, depending on the engine configuration and number of affected engines installed. This AD requires, for engines equipped with a certain cylinder head and HPP driving gear combination, removal, inspection, and replacement of the HPP driving gear before further flight and, depending on the inspection findings, replacement of the HPP shaft, cylinder head, camshaft gear, or inlet/outlet camshaft bushing. This AD also requires, for engines with an affected HPP driving gear, replacement of the HPP driving gear before further flight or within a certain number of flight hours, depending on the engine configuration and number of affected engines installed. This AD was prompted by reports of failure of the HPP driving gear and a subsequent determination that a batch of HPP driving gears may have been damaged during assembly. This AD was also prompted by an investigation which found that certain cylinder heads installed in combination with certain HPP driving gear on the same engine may cause damage to the HPP driving gear. The FAA is issuing this AD to address the unsafe condition on these products.

-----------------------------------------------------------------------
SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2021-22-20
which applied to certain Austro Engine GmbH E4 and E4P model diesel
piston engines. AD 2021-22-20 required, for engines with an affected
cylinder head, inspection of the high pressure pump (HPP) driving gear
and, depending on the results of the inspection, replacement of the HPP
driving gear with a part eligible for installation. AD 2021-22-20 also
required, for engines with an affected HPP driving gear, replacement of
the HPP driving gear before further flight or within a certain number
of flight hours, depending on the engine configuration and number of
affected engines installed. This AD requires, for engines equipped with
a certain cylinder head and HPP driving gear combination, removal,
inspection, and replacement of the HPP driving gear before further
flight and, depending on the inspection findings, replacement of the
HPP shaft, cylinder head, camshaft gear, or inlet/outlet camshaft
bushing. This AD also requires, for engines with an affected HPP
driving gear, replacement of the HPP driving gear before further flight
or within a certain number of flight hours, depending on the engine
configuration and number of affected engines installed. This AD was
prompted by reports of failure of the HPP driving gear and a subsequent
determination that a batch of HPP driving gears may have been damaged
during assembly. This AD was also prompted by an investigation which
found that certain cylinder heads installed in combination with certain
HPP driving gear on the same engine may cause damage to the HPP driving
gear. The FAA is issuing this AD to address the unsafe condition on
these products.
DATES: This AD is effective February 14, 2022.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued AD 2021-22-20, Amendment 39-21793 (86 FR 60159,
November 1, 2021), (AD 2021-22-20), for Austro Engine GmbH E4 and E4P
model diesel piston engines with a certain cylinder head or HPP driving
gear installed.
AD 2021-22-20 required, for engines with an affected cylinder head,
inspection of the HPP driving gear and, depending on the results of the
inspection, replacement of the HPP driving gear with a part eligible
for installation. AD 2021-22-20 also required, for engines with an
affected HPP driving gear, replacement of the HPP driving gear either
before further flight or within a certain number of flight hours,
depending on the engine configuration and number of affected engines
installed. AD 2021-22-20 resulted from reports of failure of the HPP
driving gear and a subsequent investigation by the manufacturer, which
determined that a certain batch of HPP driving gears may have been
damaged during assembly. The investigation also determined that
affected engines equipped with an affected cylinder head were also
subject to premature failure of the HPP driving gear. The FAA issued AD
2021-22-20 to prevent the failure of the HPP driving gear.
Actions Since AD 2021-22-20 Was Issued
Since the FAA issued AD 2021-22-20, the European Union Aviation
Safety Agency (EASA), which is the Technical Agent for the Member
States of the European Community, has issued EASA AD 2021-0274-E, dated
December 9, 2021, to address an unsafe condition for the specified
products. The MCAI states:
Occurrences were reported of HPP driving gear failure.
Subsequent investigation determined that a certain batch of HPP
driving gears was produced with a worn out assembly tool P/N
AE300T012-1. Those HPP driving gears may have been damaged during
assembly. Concurrently, it was determined that, for engines equipped
with a certain cylinder head, a stack up of tolerances exists
between the cylinder head, cylinder head backside cover, camshaft
gear and HPP driving gear. Both scenarios could result in premature
HPP driving gear failure.
This condition, if not detected and corrected, could lead to
engine in-flight shut-down with consequent forced landing, possibly
resulting in damage to the aeroplane and injury to occupants.
To address this potential unsafe condition, Austro Engine
published MSB-E4-035 to provide instructions for HPP driving gear
inspection on engines equipped with a cylinder head P/N E4A-12-500-
000, and MSB-E4-034/1 to provide instructions for replacement of
affected HPP gears, as defined in this [EASA] AD. Consequently, EASA
issued Emergency AD 2021-0203-E (later revised) to require
inspection and/or replacement of HPP gears.
Since that [EASA] AD was issued, it has been determined that an
affected cylinder head/HPP driving gear combination, as defined in
this [EASA] AD, may cause damage to the HPP driving gears. Austro
Engine issued the SB, as defined in this [EASA] AD, incorporating
the requirements of MSB-E4-034/1 and MSB-E4-035, to provide
instructions for HPP driving gear inspection and replacement. The SB
also prohibits (re-)installation of a HPP driving gear E4A-30-000-
601 or P/N E4A-30-000-201 rev. AB.1 on engines having a cylinder
head P/N E4A-12-500-000 installed. The SB further removes from the
list of affected HPP driving gears certain engines and HPPs, which
were reworked by Austro Engine pending approval of MSB-E4-034.
For the reason described above, this [EASA] AD partially retains
the requirements of EASA AD 2021-0203R1, which is superseded, and
requires replacement of the HPP driving gear on engines with an
affected cylinder head/HPP driving gear combination installed. This
[EASA] AD also provides requirements for HPP driving gear
installation.
You may obtain further information by examining the MCAI in the AD
docket at <a href="https://www.regulations.gov">https://www.regulations.gov</a> by searching for and locating
Docket No. FAA-2022-0013.
The FAA is issuing this AD to address the unsafe condition on these
products.
FAA's Determination
This product has been approved by EASA and is approved for
operation in the United States. Pursuant to our bilateral agreement
with the European Community, EASA has notified the FAA of the unsafe
condition described in the MCAI. The FAA is issuing this AD because the
agency evaluated all the relevant information provided by EASA and has
determined that the unsafe condition described previously is likely to
exist or develop in other products of the same type design.
Related Service Information Under 1 CFR Part 51
The FAA reviewed Austro Engine Mandatory Service Bulletin No. MSB-
E4-036/1, Revision No. 1, dated December 14, 2021 (MSB-E4-036/1). This
service information specifies procedures for inspecting and replacing
HPP driving gears installed on E4 and E4P model diesel piston engines
equipped with an affected cylinder head. Austro Engine MSB-E4-036/1
also identifies the applicable part number and serial numbers of
affected HPP driving gears and affected cylinder head/HPP driving gear
combinations installed on Austro Engine GmbH E4 and E4P model diesel
piston engines. 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 ADDRESSES.
AD Requirements
This AD requires, for engines equipped with an affected cylinder
head and HPP driving gear combination,
[[Page 4473]]
removal, inspection, and replacement of the HPP driving gear before
further flight and, depending on the inspection findings, replacement
of the HPP shaft, cylinder head, camshaft gear, or inlet/outlet
camshaft bushing. This AD also requires, for engines with an affected
HPP driving gear, replacement of the HPP driving gear before further
flight or within a certain number of flight hours, depending on the
engine configuration and number of affected engines installed.
Differences Between This AD and the MCAI
The MCAI requires inspection and replacement of the HPP driving
gear using Austro Engine MSB-E4-036, Initial Issue, dated November 30,
2021, while this AD requires using Austro Engine MSB-E4-036/1 to
inspect and replace the HPP driving gear.
Justification for Immediate Adoption and Determination of the Effective
Date
Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5
U.S.C. 551 et seq.) 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 providing notice and seeking
comment prior to issuance. Further, section 553(d) of the APA
authorizes agencies to make rules effective in less than thirty days,
upon a finding of good cause.
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 foregoing notice and comment prior to adoption of this rule.
The FAA received a report of occurrences of failure of the HPP driving
gear. The manufacturer subsequently determined that a certain batch of
HPP driving gears was produced with a worn out assembly tool, and may
have been damaged during assembly. The manufacturer determined that,
for engines equipped with a certain cylinder head, a stack up of
tolerances exists between the cylinder head, cylinder head cover,
camshaft gear and HPP driving gear. Since the FAA issued AD 2021-22-20
the manufacturer determined that the combination of a certain affected
cylinder head installed with a certain affected HPP driving gear on the
same engine may cause damage to the HPP driving gear. These conditions
could result in failure of the HPP driving gear. Austro Engine
subsequently published Austro Engine MSB-E4-036/1, Revision No. 1,
dated December 14, 2021, providing instructions for inspection and
replacement of certain HPP driving gears installed on Austro Engine E4
and E4P model diesel piston engines. In response, EASA issued EASA
Emergency AD 2021-0274-E, dated December 9, 2021, to require inspection
and replacement of the HPP driving gear on engines with an affected
cylinder head and HPP driving gear combination before next flight.
Failure of the HPP driving gear can result in in-flight engine
shut-down, forced landing, and damage to the airplane. The FAA
considers failure of the HPP driving gear to be an urgent safety issue
that requires immediate action to avoid damage to the airplane. For
engines with an affected cylinder head, if the HPP driving gear does
not pass the inspection required by this AD, this AD requires
inspection and possible replacement of the HPP shaft, cylinder head,
camshaft gear, and inlet/outlet camshaft bushing before further flight.
In addition, for engines with an affected HPP driving gear with a
certain number of flight hours accumulated on the HPP driving gear,
this AD requires replacement of the HPP driving gear before further
flight.
Accordingly, notice and opportunity for prior public comment are
impracticable and contrary to the public interest pursuant to 5 U.S.C.
553(b)(3)(B). In addition, the FAA finds that good cause exists
pursuant to 5 U.S.C. 553(d) for making this amendment effective in less
than 30 days, for the same reasons the FAA found good cause to forgo
notice and comment.
Comments Invited
The FAA invites you to send any written data, views, or arguments
about this final rule. Send your comments to an address listed under
ADDRESSES. Include ``Docket No. FAA-2022-0013 and Project Identifier
MCAI-2021-01371-E'' at the beginning of your comments. The most helpful
comments reference a specific portion of the proposal, explain the
reason for any recommended change, and include supporting data. The FAA
will consider all comments received by the closing date and may amend
this final rule because of those comments.
Except for Confidential Business Information (CBI) as described in
the following paragraph, and other information as described in 14 CFR
11.35, the FAA will post all comments received, without change, to
<a href="https://www.regulations.gov">https://www.regulations.gov</a>, including any personal information you
provide. The agency will also post a report summarizing each
substantive verbal contact received about this final rule.
Confidential Business Information
CBI is commercial or financial information that is both customarily
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 AD 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 AD, 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 AD. Submissions containing CBI should be sent to Wego
Wang, Aviation Safety Engineer, ECO Branch, FAA, 1200 District Avenue,
Burlington, MA 01803. Any commentary that the FAA receives which is not
specifically designated as CBI will be placed in the public docket for
this rulemaking.
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 FAA has determined
that it has good cause to adopt this rule without prior notice and
comment, RFA analysis is not required.
Costs of Compliance
The FAA estimates that this AD affects 418 engines installed on
airplanes of U.S. registry.
The FAA estimates the following costs to comply with this AD:
[[Page 4474]]
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------

----------------------------------------------------------------------------------------------------------------
The FAA estimates the following costs to do any necessary
replacements that would be required based on the results of the
inspection. The agency has no way of determining the number of aircraft
that might need this replacement:
On-Condition Costs

----------------------------------------------------------------------------------------------------------------
The FAA has included all known costs in its cost estimate.
According to the manufacturer, however, some of the costs of this AD
may be covered under warranty, thereby reducing the cost impact on
affected operators.
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
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 above, 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.
