Download as PDF 38052 Federal Register / Vol. 85, No. 123 / Thursday, June 25, 2020 / Rules and Regulations at the time the mortgage was originated. To determine whether mortgages may be counted under a particular family income level (e.g., low- or very lowincome), the income of the mortgagor is compared to the median income for the area at the time the mortgage was originated, using the appropriate percentage factor provided under § 1281.1. (b) No double-counting. A mortgage may be counted only once toward the achievement of the prospective mortgage purchase housing goal, even if it satisfies multiple criteria for the prospective mortgage purchase housing goal. (c) Application of median income. For purposes of determining an area’s median income under § 1281.1, the area is: (1) The metropolitan area, if the residence that secures the mortgage is in a metropolitan area; and (2) In all other areas, the county in which the property is located, except that where the State non-metropolitan median income is higher than the county’s median income, the area is the State non-metropolitan area. (d) Sampling not permitted. Performance under the housing goals for each year shall be based on a tabulation of each mortgage during that year; a sampling of such purchases is not acceptable. ■ 6. Amend § 1282.13 by: ■ a. Revising paragraph (b)introductory text, (b)(1) and (8); ■ b. Adding paragraph (c)(4); ■ c. Removing paragraph (d); ■ d. Redesignating paragraph (e) as paragraph (d); and ■ e. Adding new paragraph (e). The revisions and additions read as follows: § 1281.13 Special counting requirements. jbell on DSKJLSW7X2PROD with RULES * * * * * (b) Not counted. The following transactions or activities shall not be counted for purposes of the housing goals, meaning that in calculating the applicable percentage target level, they shall be excluded from both the numerator (i.e., AMA mortgages acquired during the calendar year that are for very low-income families, lowincome families, or families in lowincome areas) and the denominator (i.e., total AMA mortgages acquired during the calendar year), even if the transaction or activity would otherwise be counted under paragraph (c) of this section: (1) Purchases of participation interests in AMA mortgages from another Bank, VerDate Sep<11>2014 16:57 Jun 24, 2020 Jkt 250001 except as provided in paragraph (e) of this section; * * * * * (8) Purchases of subordinate lien mortgages; * * * * * (c) * * * (4) Non-conventional mortgages. The purchase of a non-conventional singlefamily mortgage shall be treated as a mortgage purchase for purposes of the housing goals only if the mortgage was acquired from a community-based AMA user. * * * * * (e) Mortgage participation transactions. Where two or more Banks acquire a participation interest in the same mortgage simultaneously, the mortgage will be counted on a pro rata basis for the prospective mortgage purchase housing goal for each Bank with a participation interest. ■ 7. Amend § 1281.14 by revising paragraph (a) to read as follows: § 1281.14 Determination of compliance with housing goals; notice of determination. (a) Determination of compliance with housing goals. On an annual basis, FHFA will determine each Bank’s performance under each housing goal and will publish the final determinations. FHFA will publish its final determination including the numbers and percentages for each Bank’s AMA purchases that meet each of the housing goals criteria, including loans to low-income families, loans to very low-income families, and loans to families in low-income areas, including by each of the defined categories. FHFA’s determination will include these numbers in total and separated into purchase money mortgages, refinancing mortgages, conventional mortgages, and non-conventional mortgages. * * * * * ■ 8. Amend § 1281.15 by revising paragraphs (a) and (b) to read as follows: § 1281.15 Housing plans. (a) Housing plan requirement. For any year after 2023, if the Director determines that a Bank has failed to meet any housing goal and that the achievement of the housing goal was feasible, the Director may require the Bank to submit a housing plan for approval by the Director. (b) Nature of plan. If the Director requires a housing plan, the housing plan shall: (1) Be feasible; (2) Be sufficiently specific to enable the Director to monitor compliance periodically; PO 00000 Frm 00022 Fmt 4700 Sfmt 4700 (3) Describe the specific actions that the Bank will take to achieve the housing goal for the next calendar year; (4) Address any additional matters relevant to the housing plan as required, in writing, by the Director; and (5) Address any alternative target levels for which the Bank has submitted a request under § 1281.11(c)(1). * * * * * ■ 9. Revise Subpart C to read as follows: Subpart C—Reporting Requirements § 1281.20 Reporting requirements. (a) General. Each Bank must collect and submit to FHFA any data that FHFA determines to be necessary for FHFA to evaluate transactions and activities under the Bank housing goals. (b) Reporting for prospective mortgage purchase housing goal. Each Bank must collect data on each AMA mortgage purchased by the Bank. The data must include any data elements specified by FHFA. On no less frequent than an annual basis, each Bank must submit such data to FHFA in accordance with the Data Reporting Manual. (c) Reporting for small member participation housing goal. Each Bank must collect data on AMA user asset size. On no less frequent than an annual basis, each Bank must submit such data to FHFA in accordance with the Data Reporting Manual. (d) Other reporting. Each Bank must provide to FHFA such additional reports, information, and data as FHFA may request from time to time. Mark A. Calabria, Director, Federal Housing Finance Agency.

SUPPLEMENTARY INFORMATION: Since that AD was issued, the investigations were completed, and based on the outcome, XtremeAir revised the SB (now at revision B.00), providing instructions to accomplish the repetitive inspections at a different regime. For the reason described above, this AD is revised accordingly to update the inspection interval, and to allow the removal of the prohibition to accomplish aerobatic manoeuvers. This AD is still considered an interim action and further AD action may follow. Discussion You may examine the MCAI on the internet at https://www.regulations.gov by searching for and locating Docket No. FAA–2020–0568. The FAA issued AD 2018–07–15, Amendment 39–19246 (83 FR 15036; April 9, 2018) (‘‘AD 2018–07–15’’) to address an unsafe condition on XtremeAir GmbH Model XA42 airplanes equipped with an engine mount part number XA42–7120–151. AD 2018–07– 15 required repetitive inspections of the engine mount strut junction for cracks and was based on MCAI originated by an aviation authority of another country. The FAA issued AD 2018–07–15 to detect and address cracking of the engine mount frame, which could lead to detachment of the engine in-flight and result in loss of control. Actions Since AD 2018–07–15 Was Issued Since the FAA issued AD 2018–07– 15, during a scheduled maintenance inspection of a Model XA42 airplane, an occurrence was reported of separation of both left-hand and right-hand diagonal struts of the engine mount frame. The European Union Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Community, superseded its MCAI and issued EASA AD No. 2019– 0239R1, dated December 18, 2019 (referred to after this as ‘‘the MCAI’’), to correct this unsafe condition for XtremeAir GmbH Model XA42 airplanes. The MCAI states: After that AD [EASA Emergency AD 2018– 0050–E] was issued, during a scheduled maintenance inspection of an XA42 airplane, an occurrence was reported of separation of both left-hand and right-hand diagonal struts of the affected part. This condition, if not detected and corrected, could lead to in-flight detachment of the engine, possibly resulting in loss of control of the airplane. Prompted by this new finding, XtremeAir issued the SB [XtremeAir Service Bulletin SB–XA42–2019–008, Issue A.00] to provide limitations and inspection instructions. Consequently, EASA issued Emergency AD 2019–0239–E, retaining the requirements of EASA Emergency AD 2018–0050–E, which was superseded, reducing the inspection interval to each pre-flight check and requiring an Aircraft Flight Manual (AFM) limitation to prohibit aerobatic manoeuvers, and installation of a corresponding placard. PO 00000 Frm 00023 Fmt 4700 Sfmt 4700 Relative Service Information Under 1 CFR Part 51 The FAA reviewed XtremeAir GmbH Mandatory Service Bulletin SB–XA42– 2019–008, Issue B.00, dated December 4, 2019. The service information contains procedures for inspection of the area of the junction of the left-hand and right-hand diagonal struts of the engine mount, forward of the oil cooler, for cracks. 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. FAA’s Determination and Requirements of the AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with this State of Design Authority, it has notified the FAA of the unsafe condition described in the MCAI and service information referenced above. The FAA is issuing this AD because it evaluated all information provided by the State of Design Authority and determined the unsafe condition exists and is likely to exist or develop on other products of the same type design. FAA’s Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because cracking of the engine mount frame could lead to in-flight detachment of the engine and result in loss of control of the airplane. AD 2018– 07–15 only required an inspection of the left-hand diagonal strut. Since AD 2018–07–15 was issued, an occurrence was reported of separation of both the left-hand and right-hand diagonal struts of the engine mount frame. The E:\FR\FM\25JNR1.SGM 25JNR1 38054 Federal Register / Vol. 85, No. 123 / Thursday, June 25, 2020 / Rules and Regulations additional inspection required by this AD is necessary to detect cracks in the right-hand diagonal strut of the engine mount frame. Therefore, the FAA finds that notice and opportunity for public comment before issuing this AD are impracticable. In addition, for the reasons stated above, the FAA finds that good cause exists for making this amendment effective in fewer than 30 days. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and the FAA did not precede it by notice and opportunity for public comment. The FAA invites you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2020–0568; Project Identifier MCAI–2020–00505–A’’ at the beginning of your comments. The FAA specifically invites comments on the overall regulatory, economic, environmental, and energy aspects of this AD. The FAA will consider all comments received by the closing date and may amend this AD because of those comments. The FAA will post all comments we receive, without change, to https:// www.regulations.gov, including any personal information you provide. The FAA will also post a report summarizing each substantive verbal contact received about this AD. jbell on DSKJLSW7X2PROD with RULES Costs of Compliance The FAA estimates that this AD will affect 16 products of U.S. registry. The FAA also estimates that it will take 0.5 work-hour per product per inspection cycle to inspect the diagonal struts of the engine mount. The average labor rate is $85 per work-hour. Required parts would cost about $0 per product. Based on these figures, the FAA estimates the cost of the inspection on U.S. operators to be $680.00 or $42.50 per product per inspection cycle. In addition, the FAA estimates that replacing an engine mount, if necessary, will take 24 work-hours and require parts costing $5,000, for a cost of $7,040 per product. The FAA has no way of determining the number of products that may need this action. 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. VerDate Sep<11>2014 16:57 Jun 24, 2020 Jkt 250001 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 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 notice and comment, RFA analysis is not required. 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 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. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

(a) Effective Date This airworthiness directive (AD) becomes effective July 15, 2020. (b) Affected ADs This AD replaces AD 2018–07–15, Amendment 39–19246 (83 FR 15036, April 9, 2018). (c) Applicability This AD applies to XtremeAir GmbH Model XA42 airplanes, all serial numbers, certificated in any category. (d) Subject Air Transport Association of America (ATA) Code 71: Power Plant. (e) Reason This AD was prompted by mandatory continuing airworthiness information (MCAI) issued by the aviation authority of another country to identify and address an unsafe condition on an aviation product. The MCAI describes the unsafe condition as cracking of the diagonal struts of the engine mount frame. The FAA is issuing this AD to prevent the in-flight detachment of the engine, which could result in loss of control of the airplane. (f) Actions and Compliance For airplanes with an engine mount part number (P/N) XA42–7120–151 installed, unless already done, do the following actions in paragraphs (f)(1) and (2) of this AD. (1) Before the next acrobatic flight after July 15, 2020 (the effective date of this AD) or before the engine mount accumulates 50 hours time-in-service (TIS), whichever occurs later, and thereafter at intervals not to exceed 10 acrobatic flights, visually inspect the junction of the left-hand and right-hand diagonal struts of the engine mount, forward of the oil cooler, for cracks in the area shown in the photographs in XtremeAir GmbH Mandatory Service Bulletin SB–XA42–2019– 008, Issue B.00, dated December 4, 2019. For purposes of this AD, an acrobatic flight is counted for each flight during which a load factor of 6g is exceeded. (i) If there is a crack, before further flight, replace the engine mount with an airworthy engine mount with zero hours TIS, an engine mount that has passed the inspection required by this AD, or an engine mount that is not P/N XA42–7120–151. (ii) After completing the initial inspection, begin or continue to count the acrobatic flights and record in the maintenance records. (2) As of July 15, 2020 (the effective date of this AD), do not install on the airplane an engine mount P/N XA42–7120–151 unless it is an airworthy engine mount with zero hours TIS or is an engine mount that has passed the inspection required by this AD. (g) Installation Prohibition For airplanes without engine mount P/N XA42–7120–151 installed, as of July 15, 2020 (the effective date of this AD), do not install engine mount P/N XA42–7120–151.

SUPPLEMENTARY INFORMATION: Discussion The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to certain The Boeing Company Model 737–8 and 737–9 airplanes. The NPRM published in the Federal Register on February 26, 2020 (85 FR 11000). The NPRM was prompted by a report that certain exterior fairing panels on the top of the engine nacelle and strut (the thumbnail fairing and mid strut fairing panels) may not have the quality of electrical bonding necessary to ensure adequate shielding of the underlying wiring from the electromagnetic effects of HIRF, which could potentially lead to a dual-engine power loss event and/or display of hazardously misleading primary propulsion parameters. The NPRM proposed to require a detailed inspection of the thumbnail fairing panels and mid strut fairing panels for excessive rework of the metallic (aluminum foil) inner surface layer, replacement of any excessively reworked panels, and modification of the thumbnail fairing assembly to ensure adequate bonding. The FAA is issuing this AD to address this condition, which could result in a forced off-airport landing or excessive flightcrew workload. Comments The FAA gave the public the opportunity to participate in developing this final rule. The FAA received comments from several organizations and individuals.

SUPPLEMENTARY INFORMATION:

Discussion

    The FAA issued AD 2018-07-15, Amendment 39-19246 (83 FR 15036; 
April 9, 2018) (``AD 2018-07-15'') to address an unsafe condition on 
XtremeAir GmbH Model XA42 airplanes equipped with an engine mount part 
number XA42-7120-151. AD 2018-07-15 required repetitive inspections of 
the engine mount strut junction for cracks and was based on MCAI 
originated by an aviation authority of another country. The FAA issued 
AD 2018-07-15 to detect and address cracking of the engine mount frame, 
which could lead to detachment of the engine in-flight and result in 
loss of control.

Actions Since AD 2018-07-15 Was Issued

    Since the FAA issued AD 2018-07-15, during a scheduled maintenance 
inspection of a Model XA42 airplane, an occurrence was reported of 
separation of both left-hand and right-hand diagonal struts of the 
engine mount frame.
    The European Union Aviation Safety Agency (EASA), which is the 
Technical Agent for the Member States of the European Community, 
superseded its MCAI and issued EASA AD No. 2019-0239R1, dated December 
18, 2019 (referred to after this as ``the MCAI''), to correct this 
unsafe condition for XtremeAir GmbH Model XA42 airplanes. The MCAI 
states:

    After that AD [EASA Emergency AD 2018-0050-E] was issued, during 
a scheduled maintenance inspection of an XA42 airplane, an 
occurrence was reported of separation of both left-hand and right-
hand diagonal struts of the affected part.
    This condition, if not detected and corrected, could lead to in-
flight detachment of the engine, possibly resulting in loss of 
control of the airplane.
    Prompted by this new finding, XtremeAir issued the SB [XtremeAir 
Service Bulletin SB-XA42-2019-008, Issue A.00] to provide 
limitations and inspection instructions. Consequently, EASA issued 
Emergency AD 2019-0239-E, retaining the requirements of EASA 
Emergency AD 2018-0050-E, which was superseded, reducing the 
inspection interval to each pre-flight check and requiring an 
Aircraft Flight Manual (AFM) limitation to prohibit aerobatic 
manoeuvers, and installation of a corresponding placard.
    Since that AD was issued, the investigations were completed, and 
based on the outcome, XtremeAir revised the SB (now at revision 
B.00), providing instructions to accomplish the repetitive 
inspections at a different regime.
    For the reason described above, this AD is revised accordingly 
to update the inspection interval, and to allow the removal of the 
prohibition to accomplish aerobatic manoeuvers.
    This AD is still considered an interim action and further AD 
action may follow.

0568.

Relative Service Information Under 1 CFR Part 51

    The FAA reviewed XtremeAir GmbH Mandatory Service Bulletin SB-XA42-
2019-008, Issue B.00, dated December 4, 2019. The service information 
contains procedures for inspection of the area of the junction of the 
left-hand and right-hand diagonal struts of the engine mount, forward 
of the oil cooler, for cracks. 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.

FAA's Determination and Requirements of the AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to the FAA's bilateral agreement with this State of Design Authority, 
it has notified the FAA of the unsafe condition described in the MCAI 
and service information referenced above. The FAA is issuing this AD 
because it evaluated all information provided by the State of Design 
Authority and determined the unsafe condition exists and is likely to 
exist or develop on other products of the same type design.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
cracking of the engine mount frame could lead to in-flight detachment 
of the engine and result in loss of control of the airplane. AD 2018-
07-15 only required an inspection of the left-hand diagonal strut. 
Since AD 2018-07-15 was issued, an occurrence was reported of 
separation of both the left-hand and right-hand diagonal struts of the 
engine mount frame. The

[[Page 38054]]

additional inspection required by this AD is necessary to detect cracks 
in the right-hand diagonal strut of the engine mount frame. Therefore, 
the FAA finds that notice and opportunity for public comment before 
issuing this AD are impracticable. In addition, for the reasons stated 
above, the FAA finds that good cause exists for making this amendment 
effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and the FAA did not precede it by notice and opportunity for 
public comment. The FAA invites you to send any written relevant data, 
views, or arguments about this AD. Send your comments to an address 
listed under the ADDRESSES section. Include ``Docket No. FAA-2020-0568; 
Project Identifier MCAI-2020-00505-A'' at the beginning of your 
comments. The FAA specifically invites comments on the overall 
regulatory, economic, environmental, and energy aspects of this AD. The 
FAA will consider all comments received by the closing date and may 
amend this AD because of those comments.
    The FAA will post all comments we receive, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The FAA will also post a report summarizing each substantive 
verbal contact received about this AD.

Costs of Compliance

    The FAA estimates that this AD will affect 16 products of U.S. 
registry. The FAA also estimates that it will take 0.5 work-hour per 
product per inspection cycle to inspect the diagonal struts of the 
engine mount. The average labor rate is $85 per work-hour. Required 
parts would cost about $0 per product.
    Based on these figures, the FAA estimates the cost of the 
inspection on U.S. operators to be $680.00 or $42.50 per product per 
inspection cycle.
    In addition, the FAA estimates that replacing an engine mount, if 
necessary, will take 24 work-hours and require parts costing $5,000, 
for a cost of $7,040 per product. The FAA has no way of determining the 
number of products that may need this action.

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 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 notice and comment, 
RFA analysis is not required.

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 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.

a. Removing Airworthiness Directive 2018-07-15, Amendment 39-19246 (83 
FR 15036, April 9, 2018); and
0
b. Adding the following new AD:

2020-13-03 XtremeAir GmbH Airplanes: Amendment 39-21148; Docket No. 
FAA-2020-0568; Project Identifier MCAI-2020-00505-A.

(a) Effective Date

    This airworthiness directive (AD) becomes effective July 15, 
2020.

(b) Affected ADs

    This AD replaces AD 2018-07-15, Amendment 39-19246 (83 FR 15036, 
April 9, 2018).

(c) Applicability

    This AD applies to XtremeAir GmbH Model XA42 airplanes, all 
serial numbers, certificated in any category.

(d) Subject

    Air Transport Association of America (ATA) Code 71: Power Plant.

(e) Reason

    This AD was prompted by mandatory continuing airworthiness 
information (MCAI) issued by the aviation authority of another 
country to identify and address an unsafe condition on an aviation 
product. The MCAI describes the unsafe condition as cracking of the 
diagonal struts of the engine mount frame. The FAA is issuing this 
AD to prevent the in-flight detachment of the engine, which could 
result in loss of control of the airplane.

(f) Actions and Compliance

    For airplanes with an engine mount part number (P/N) XA42-7120-
151 installed, unless already done, do the following actions in 
paragraphs (f)(1) and (2) of this AD.
    (1) Before the next acrobatic flight after July 15, 2020 (the 
effective date of this AD) or before the engine mount accumulates 50 
hours time-in-service (TIS), whichever occurs later, and thereafter 
at intervals not to exceed 10 acrobatic flights, visually inspect 
the junction of the left-hand and right-hand diagonal struts of the 
engine mount, forward of the oil cooler, for cracks in the area 
shown in the photographs in XtremeAir GmbH Mandatory Service 
Bulletin SB-XA42-2019-008, Issue B.00, dated December 4, 2019. For 
purposes of this AD, an acrobatic flight is counted for each flight 
during which a load factor of 6g is exceeded.
    (i) If there is a crack, before further flight, replace the 
engine mount with an airworthy engine mount with zero hours TIS, an 
engine mount that has passed the inspection required by this AD, or 
an engine mount that is not P/N XA42-7120-151.
    (ii) After completing the initial inspection, begin or continue 
to count the acrobatic flights and record in the maintenance 
records.
    (2) As of July 15, 2020 (the effective date of this AD), do not 
install on the airplane an engine mount P/N XA42-7120-151 unless it 
is an airworthy engine mount with zero hours TIS or is an engine 
mount that has passed the inspection required by this AD.

(g) Installation Prohibition

    For airplanes without engine mount P/N XA42-7120-151 installed, 
as of July 15, 2020 (the effective date of this AD), do not install 
engine mount P/N XA42-7120-151.
