SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR VerDate Sep<11>2014 15:49 Aug 08, 2018 Jkt 244001 part 39 by adding an AD that would apply to all Airbus SAS Model A318– 111 and –112 airplanes, Model A319– 111, –112, –113, –114, and –115 airplanes, Model A320–211, –212, –214, and –216 airplanes, and Model A321– 111, –112, –211, –212, and –213 airplanes. The NPRM published in the Federal Register on March 9, 2018 (83 FR 10411). The NPRM was prompted by a report of a production quality deficiency on the inner retainer installed on link assemblies of the aft engine mount, which could result in failure of the retainer. The NPRM proposed to require modifying and reidentifying the aft engine mount assemblies. We are issuing this AD to address non-conforming retainers of the aft engine mount. This condition could result in loss of the locking feature of the nuts of the inner and outer pins; loss of the pins will result in the aft mount engine link no longer being secured to the aft engine mount, possibly resulting in damage to the airplane. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017–0251, dated December 15, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Airbus SAS Model A318–111 and –112 airplanes, Model A319–111, –112, –113, –114, and –115 airplanes, Model A320–211, –212, –214, and –216 airplanes, and Model A321–111, –112, –211, –212, and –213 airplanes. The MCAI states: During in-service inspections, several aft engine mount inner retainers, fitted on aeroplanes equipped with CFM56–5A/5B engines, were found broken. Investigation identified that the main cause of crack initiation was the vibration dynamic effect that affects the retainers, and that the ‘‘dull’’ surface finish pitting is an aggravating factor when compared with the ‘‘bright’’ surface finishing. This condition, if not detected and corrected, could lead to in-flight loss of an aft engine mount link, possibly resulting in damage to the aeroplane and/or injury to persons on the ground. To address this potential unsafe condition, Airbus issued Alert Operators Transmission (AOT) A71N001–12 (later revised) and EASA issued AD 2013–0050 [which corresponds to FAA AD 2014–14–06, Amendment 39–17901 (79 FR 42655, July 23, 2014)], later superseded by EASA AD 2015–0021 [which corresponds to FAA AD 2016–14–09, Amendment 39–18590 (81 FR 44989, July 12, 2016) (‘‘AD 2016–14–09’’)], requiring repetitive detailed inspections (DET) of all aft engine mount inner retainers and, depending on findings, their replacement. PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 39327 After EASA AD 2015–0021 was issued, a production quality deficiency was identified by Airbus and Goodrich Aerostructures, the engine mount retainer manufacturer, on the inner retainer, Part Number (P/N) 238–0252– 505, installed in the three link assemblies of the engine mount fitted on CFM56–5A/5B engines. Airbus issued AOT A71N011–15 and Service Bulletin (SB) A320–71–1070, providing a list of affected parts and applicable corrective actions. Consequently, EASA issued AD 2016–0010 (later revised), retaining the requirements of EASA AD 2015–0021, which was superseded, and in addition requiring the identification and replacement of all nonconforming aft engine mount inner retainers [EASA AD 2016–0010 R1 corresponds to FAA AD 2017–04–10, Amendment 39–18805 (82 FR 11791, February 27, 2017) (‘‘AD 2017– 04–10’’)]. After that [EASA] AD was issued, a new engine mount retainer was developed by Goodrich Aerostructures to improve the retainer efficiency. For retrofit purposes, Goodrich Aerostructures issued SB RA32071–164, and Airbus issued SB A320– 71–1071, providing instructions to modify and re-identify the engine mount assemblies as instructed in the Goodrich Aerostructures SB. Subsequently, it was observed that, on aeroplanes equipped with certain engines fitted with a Turbine Rear Frame (TRF) with 4 lugs configuration, the installation of the new engine mount retainers can lead to interference, and Goodrich Aerostructures revised SB RA32071–164, providing instructions not to install the new engine retainers on affected engines. Airbus SB A320–71–1071 is expected to be revised accordingly. For engines fitted with a TRF with 4 lugs, a new installation (potentially requiring different engine mount retainers) is being developed by Goodrich Aerospace and Airbus. Consequently, EASA issued AD 2017– 0138, retaining the requirements of EASA AD 2016–0010R1, which was superseded, and, except for aeroplanes equipped with engines fitted with a TRF with 4 lugs configuration, requiring modification and identification of aft engine mount assemblies as terminating action for the repetitive inspections of the retainers. That [EASA] AD also included additional instructions applicable to installation of engines fitted with a TRF with 4 lugs configuration. Since EASA AD 2017–0138 was issued, it was determined that installation of new engine mount assemblies must not be allowed for some specific engine configurations, and that installation of Goodrich Aerostructures SB RA32071–164 alone can be referred to, in order to accomplish the terminating action as required by that [EASA] AD. For the reason described above, this [EASA] AD retains the requirements of EASA AD 2017–0138, which is superseded, adds reference to Goodrich Aerostructures SB RA32071–164 * * *, and introduces new requirement for aeroplanes equipped with engines fitted with a TRF with 4 lugs configuration. This AD does not supersede AD 2017–04–10. Rather, we have E:\FR\FM\09AUR1.SGM 09AUR1 39328 Federal Register / Vol. 83, No. 154 / Thursday, August 9, 2018 / Rules and Regulations determined that a stand-alone AD is more appropriate to address the changes in the MCAI. This AD requires modifying and re-identifying the aft engine mount assemblies. Accomplishment of the required actions terminates the repetitive detailed inspections required by paragraph (l) of AD 2016–14–09, and serve as a method of compliance for the requirements of paragraph (g) of AD 2017–04–10. You may examine the MCAI in the AD docket on the internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2018– 0165. Comments We gave the public the opportunity to participate in developing this final rule. The following presents the comments received on the NPRM and the FAA’s response to each comment. Support for the NPRM Air Line Pilots Association, International (ALPA) supported the intent of the NPRM. Request To Refer to Current Revision of Service Information Airbus SAS noted that it issued Service Bulletin A320–71–1071, Revision 01, dated October 17, 2017, and requested that this revision of the service bulletin be included in the final rule. The original issue of Service Bulletin A320–71–1071, dated November 8, 2016, was referred to in the proposed AD. We agree with the commenter’s request. Airbus Service Bulletin A320– 71–1071, Revision 01, dated October 17, 2017, clarifies certain notes and references but makes no substantive changes to Airbus Service Bulletin A320–71–1071, dated November 8, 2016, as proposed in the NPRM. Furthermore, while Airbus Service Bulletin A320–71–1071, Revision 01, dated October 17, 2017, expands the effectivity, the applicability of this AD has not been changed. We have revised the preamble of this final rule and paragraph (h) of this AD to include Airbus Service Bulletin A320–71–1071, Revision 01, dated October 17, 2017. We have also added paragraph (n) to this AD to provide credit for actions done prior to the effective date of this AD using the original issue of Airbus Service Bulletin A320–71–1071, dated November 8, 2016. We redesignated subsequent paragraphs accordingly. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting this final rule with the changes described previously and minor editorial changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the NPRM. We also determined that these changes will not increase the economic burden on any operator or increase the scope of this final rule. Related Service Information Under 1 CFR Part 51 Airbus SAS has issued Service Bulletin A320–71–1071, Revision 01, dated October 17, 2017. Goodrich Aerostructures has issued Service Bulletin RA32071–164, Revision 1, dated July 19, 2017. The service information describes procedures for modifying and re-identifying the aft engine mount retainer assembly. These documents are distinct since they apply to different airplane models in different configurations. 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. Costs of Compliance We estimate that this AD affects 500 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Action Labor cost Modification and re-identification ..... 20 work-hours × $85 per hour = $1,700 ....................... sradovich on DSK3GMQ082PROD with RULES 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. We are 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 VerDate Sep<11>2014 15:49 Aug 08, 2018 Jkt 244001 Parts cost products identified in this rulemaking action. This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. Regulatory Findings We 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, PO 00000 Frm 00006 Fmt 4700 Sfmt 4700 $3,152 Cost per product $4,852 Cost on U.S. operators $2,426,000 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, 2. Is not a ‘‘significant rule’’ under the DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979), 3. Will not affect intrastate aviation in Alaska, and 4. Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to all Airbus SAS Model A318-
111 and -112 airplanes, Model A319-111, -112, -113, -114, and -115 
airplanes, Model A320-211, -212, -214, and -216 airplanes, and Model 
A321-111, -112, -211, -212, and -213 airplanes. The NPRM published in 
the Federal Register on March 9, 2018 (83 FR 10411). The NPRM was 
prompted by a report of a production quality deficiency on the inner 
retainer installed on link assemblies of the aft engine mount, which 
could result in failure of the retainer. The NPRM proposed to require 
modifying and re-identifying the aft engine mount assemblies.
    We are issuing this AD to address non-conforming retainers of the 
aft engine mount. This condition could result in loss of the locking 
feature of the nuts of the inner and outer pins; loss of the pins will 
result in the aft mount engine link no longer being secured to the aft 
engine mount, possibly resulting in damage to the airplane.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2017-0251, dated December 15, 2017 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A318-111 and -112 
airplanes, Model A319-111, -112, -113, -114, and -115 airplanes, Model 
A320-211, -212, -214, and -216 airplanes, and Model A321-111, -112, -
211, -212, and -213 airplanes. The MCAI states:

    During in-service inspections, several aft engine mount inner 
retainers, fitted on aeroplanes equipped with CFM56-5A/5B engines, 
were found broken. Investigation identified that the main cause of 
crack initiation was the vibration dynamic effect that affects the 
retainers, and that the ``dull'' surface finish pitting is an 
aggravating factor when compared with the ``bright'' surface 
finishing.
    This condition, if not detected and corrected, could lead to in-
flight loss of an aft engine mount link, possibly resulting in 
damage to the aeroplane and/or injury to persons on the ground.
    To address this potential unsafe condition, Airbus issued Alert 
Operators Transmission (AOT) A71N001-12 (later revised) and EASA 
issued AD 2013-0050 [which corresponds to FAA AD 2014-14-06, 
Amendment 39-17901 (79 FR 42655, July 23, 2014)], later superseded 
by EASA AD 2015-0021 [which corresponds to FAA AD 2016-14-09, 
Amendment 39-18590 (81 FR 44989, July 12, 2016) (``AD 2016-14-
09'')], requiring repetitive detailed inspections (DET) of all aft 
engine mount inner retainers and, depending on findings, their 
replacement.
    After EASA AD 2015-0021 was issued, a production quality 
deficiency was identified by Airbus and Goodrich Aerostructures, the 
engine mount retainer manufacturer, on the inner retainer, Part 
Number (P/N) 238-0252-505, installed in the three link assemblies of 
the engine mount fitted on CFM56-5A/5B engines. Airbus issued AOT 
A71N011-15 and Service Bulletin (SB) A320-71-1070, providing a list 
of affected parts and applicable corrective actions.
    Consequently, EASA issued AD 2016-0010 (later revised), 
retaining the requirements of EASA AD 2015-0021, which was 
superseded, and in addition requiring the identification and 
replacement of all non-conforming aft engine mount inner retainers 
[EASA AD 2016-0010 R1 corresponds to FAA AD 2017-04-10, Amendment 
39-18805 (82 FR 11791, February 27, 2017) (``AD 2017-04-10'')].
    After that [EASA] AD was issued, a new engine mount retainer was 
developed by Goodrich Aerostructures to improve the retainer 
efficiency. For retrofit purposes, Goodrich Aerostructures issued SB 
RA32071-164, and Airbus issued SB A320-71-1071, providing 
instructions to modify and re-identify the engine mount assemblies 
as instructed in the Goodrich Aerostructures SB. Subsequently, it 
was observed that, on aeroplanes equipped with certain engines 
fitted with a Turbine Rear Frame (TRF) with 4 lugs configuration, 
the installation of the new engine mount retainers can lead to 
interference, and Goodrich Aerostructures revised SB RA32071-164, 
providing instructions not to install the new engine retainers on 
affected engines. Airbus SB A320-71-1071 is expected to be revised 
accordingly. For engines fitted with a TRF with 4 lugs, a new 
installation (potentially requiring different engine mount 
retainers) is being developed by Goodrich Aerospace and Airbus.
    Consequently, EASA issued AD 2017-0138, retaining the 
requirements of EASA AD 2016-0010R1, which was superseded, and, 
except for aeroplanes equipped with engines fitted with a TRF with 4 
lugs configuration, requiring modification and identification of aft 
engine mount assemblies as terminating action for the repetitive 
inspections of the retainers. That [EASA] AD also included 
additional instructions applicable to installation of engines fitted 
with a TRF with 4 lugs configuration.
    Since EASA AD 2017-0138 was issued, it was determined that 
installation of new engine mount assemblies must not be allowed for 
some specific engine configurations, and that installation of 
Goodrich Aerostructures SB RA32071-164 alone can be referred to, in 
order to accomplish the terminating action as required by that 
[EASA] AD.
    For the reason described above, this [EASA] AD retains the 
requirements of EASA AD 2017-0138, which is superseded, adds 
reference to Goodrich Aerostructures SB RA32071-164 * * *, and 
introduces new requirement for aeroplanes equipped with engines 
fitted with a TRF with 4 lugs configuration.

    This AD does not supersede AD 2017-04-10. Rather, we have

[[Page 39328]]

determined that a stand-alone AD is more appropriate to address the 
changes in the MCAI. This AD requires modifying and re-identifying the 
aft engine mount assemblies. Accomplishment of the required actions 
terminates the repetitive detailed inspections required by paragraph 
(l) of AD 2016-14-09, and serve as a method of compliance for the 
requirements of paragraph (g) of AD 2017-04-10. You may examine the 
MCAI in the AD docket on the internet at http://www.regulations.gov by 
searching for and locating Docket No. FAA-2018-0165.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. The following presents the comments received on the 
NPRM and the FAA's response to each comment.

Support for the NPRM

    Air Line Pilots Association, International (ALPA) supported the 
intent of the NPRM.

Request To Refer to Current Revision of Service Information

    Airbus SAS noted that it issued Service Bulletin A320-71-1071, 
Revision 01, dated October 17, 2017, and requested that this revision 
of the service bulletin be included in the final rule. The original 
issue of Service Bulletin A320-71-1071, dated November 8, 2016, was 
referred to in the proposed AD.
    We agree with the commenter's request. Airbus Service Bulletin 
A320-71-1071, Revision 01, dated October 17, 2017, clarifies certain 
notes and references but makes no substantive changes to Airbus Service 
Bulletin A320-71-1071, dated November 8, 2016, as proposed in the NPRM. 
Furthermore, while Airbus Service Bulletin A320-71-1071, Revision 01, 
dated October 17, 2017, expands the effectivity, the applicability of 
this AD has not been changed. We have revised the preamble of this 
final rule and paragraph (h) of this AD to include Airbus Service 
Bulletin A320-71-1071, Revision 01, dated October 17, 2017. We have 
also added paragraph (n) to this AD to provide credit for actions done 
prior to the effective date of this AD using the original issue of 
Airbus Service Bulletin A320-71-1071, dated November 8, 2016. We 
redesignated subsequent paragraphs accordingly.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this final rule with the changes described previously and minor 
editorial changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related Service Information Under 1 CFR Part 51

    Airbus SAS has issued Service Bulletin A320-71-1071, Revision 01, 
dated October 17, 2017. Goodrich Aerostructures has issued Service 
Bulletin RA32071-164, Revision 1, dated July 19, 2017. The service 
information describes procedures for modifying and re-identifying the 
aft engine mount retainer assembly. These documents are distinct since 
they apply to different airplane models in different configurations.
    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.

Costs of Compliance

    We estimate that this AD affects 500 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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.
    We are 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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

Regulatory Findings

    We 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,
    2. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    3. Will not affect intrastate aviation in Alaska, and
    4. Will not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.

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

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 (AD):

2018-16-02 Airbus SAS: Amendment 39-19342; Docket No. FAA-2018-0165; 
Product Identifier 2017-NM-122-AD.

(a) Effective Date

    This AD is effective September 13, 2018.

(b) Affected ADs

    This AD affects AD 2016-14-09, Amendment 39-18590 (81 FR 44989, 
July 12, 2016) (``AD 2016-14-09''); and AD 2017-04-10, Amendment 39-
18805 (82 FR 11791, February 27, 2017) (``AD 2017-04-10'').

(c) Applicability

    This AD applies to the Airbus SAS airplanes identified in 
paragraphs (c)(1) through (c)(4) of this AD, certificated in any 
category, all manufacturer serial numbers.
    (1) Model A318-111 and -112 airplanes.
    (2) Model A319-111, -112, -113, -114, and -115 airplanes.
    (3) Model A320-211, -212, -214, and -216 airplanes.
    (4) Model A321-111, -112, -211, -212, and -213 airplanes.

(d) Subject

    Air Transport Association (ATA) of America Code 71, Powerplant.

(e) Reason

    This AD was prompted by a report of a production quality 
deficiency on the inner retainer installed on link assemblies of the 
aft engine mount, which could result in failure of the retainer. We 
are issuing this AD to address non-conforming retainers of the aft 
engine mount. This condition could result in loss of the locking 
feature of the nuts of the inner and outer pins; loss of the pins 
will result in the aft mount engine link no longer being secured to 
the aft engine mount, possibly resulting in damage to the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Definitions

    (1) For the purpose of this AD: A Group 1 airplane has an aft 
engine mount assembly installed, having a part number (P/N) 
identified as ``Old P/N'' in figure 1 to paragraphs (g)(1), (h), 
(i), (j), (k), and (l) of this AD. A Group 2 airplane does not have 
any aft engine mount assembly installed having a part number 
identified as ``Old P/N'' in figure 1 to paragraphs (g)(1), (h), 
(i), (j), (k), and (l) of this AD.

    (2) For the purpose of this AD, a 4-lugs engine is a CFM56-5A1, 
CFM56-5A3, CFM56-5A4, CFM56-5A4/F, CFM56-5A5, or CFM56-5A5/F engine, 
fitted with a turbine rear frame (TRF) having a part number as 
identified in figure 2 to paragraph (g)(2) of this AD.

(h) Modification

    For Group 1 airplanes: Within 48 months after the effective date 
of this AD, except for 4-lugs engines, modify the aft engine mount 
assembly, having a part number identified as ``Old P/N'' in figure 1 
to paragraphs (g)(1), (h), (i), (j), (k), and (l) of this AD, and 
re-identify it with the corresponding part number identified as 
``New P/N'' in figure 1 to paragraphs (g)(1), (h), (i), (j), (k), 
and (l) of this AD, in accordance with the Accomplishment 
Instructions of Airbus Service Bulletin A320-71-1071, Revision 01, 
dated October 17, 2017; or Goodrich Aerostructures Service Bulletin 
RA32071-164, Revision 1, dated July 19, 2017.

(i) Other Acceptable Method of Compliance

    Replacement on an airplane of each aft engine mount assembly, 
identified as ``Old P/N'' in figure 1 to paragraphs (g)(1), (h), 
(i), (j), (k), and (l) of this AD, with a corresponding aft engine 
mount assembly, identified as ``New P/N'' in figure 1 to paragraphs 
(g)(1), (h), (i), (j), (k), and (l) of this AD, is an acceptable 
method to comply with the requirements of paragraph (h) of this AD 
for that airplane.

(j) Identification of Certain Airplanes That Do Not Have Affected Parts

    An airplane on which Airbus Modification 158435 has been 
embodied in production and on which it can be positively determined 
that no aft engine mount assembly, identified as ``Old P/N'' in 
figure 1 to paragraphs (g)(1), (h), (i), (j), (k), and (l) of this 
AD, is installed, is considered a Group 2 airplane. A review of 
airplane maintenance records is acceptable to make this 
determination, if it can be conclusively determined that no aft 
engine mount assembly identified as ``Old P/N'' in figure 1 to 
paragraphs (g)(1), (h), (i), (j), (k), and (l) of this AD is 
installed. Group 2 airplanes are not affected by the requirements of 
paragraph (h) of this AD.

(k) Parts Installation Prohibition

    (1) For Group 1 airplanes: Do not install an aft engine mount 
assembly identified as ``Old P/N'' in figure 1 to paragraphs (g)(1), 
(h), (i), (j), (k), and (l) of this AD on any airplane after 
modification of the airplane as required by paragraph (h) of this 
AD, or after any replacement specified in paragraph (i) of this AD.
    (2) For Group 2 airplanes: As of the effective date of this AD, 
do not install an aft engine mount assembly identified as ``Old P/
N'' in figure 1 to paragraphs (g)(1), (h), (i), (j), (k), and (l) of 
this AD on any airplane.
    (3) For airplanes equipped with a 4-lugs engine (left-hand (LH) 
or right-hand (RH) side): As of the effective date of this AD, do 
not modify any aft engine mount assembly identified as ``Old P/N'' 
in figure 1 to paragraphs (g)(1), (h), (i), (j), (k), and (l) of 
this AD, as required by paragraph (h) of this AD, and do not install 
on an affected engine pylon (LH or RH) any aft engine mount assembly 
identified as ``New P/N'' in figure 1 to paragraphs (g)(1), (h), 
(i), (j), (k), and (l) of this AD.

(l) 4-Lugs Engine Installation

    (1) From the effective date of this AD, it is allowed to install 
or reinstall a 4-lugs engine on an airplane (LH or RH) provided that 
the airplane is equipped with an aft engine mount assembly 
identified as ``Old P/N'' in figure 1 to paragraphs (g)(1), (h), 
(i), (j), (k), and (l) of this AD on the affected engine pylon (LH 
or RH).
