          Textron Canada; Airbus Helicopters (AH), formerly Eurocopter, Eurocopter France, Aerospatiale;
          Airbus Helicopters Deutschland GmbH (AHD), formerly Eurocopter Deutschland GmbH; Airbus
          Helicopters Inc., formerly American Eurocopter LLC; MD Helicopters, Inc. (MDHI), formerly
          McDonnell Douglas Helicopter Systems; and Sikorsky Aircraft Corporation.

          Applicability:
          This AD applies to the following helicopters, when equipped with a Goodrich hoist having a Part
          Number (P/N) as listed in Table 1 of this AD: Leonardo AW109SP, AB139, AW139 and AB412 (all
          Models) helicopters, all serial numbers (s/n); BTI 212, 214 and 412 helicopters (all Models), all s/n;
          BTCL 429 and 430 helicopters, all s/n; AH AS 365 N3, AS 332 L2 and EC225 LP helicopters, all s/n;
          AHD MBB-BK117 C-2, EC135 and EC635 (all Models) helicopters, all s/n; MDHI MD900 helicopters,
          all s/n; and Sikorsky S-61 (all Models), S-76A, S-76B, S-76C and S-92A helicopters, all s/n.

          Reason:
          During a maintenance check flight with an MBB-BK117 C-2 helicopter, a dummy load of 552 lb
          (250 kg) was picked up in order to conduct a “maximum load cycle” on the rescue hoist. The cable
          reeled-out without further command of the operator, causing the test dummy load to impact the
          ground. The results of further examinations on the subject hoist determined that the overload
          clutch had failed. The overload clutch design is common to all Goodrich externally mounted rescue
          hoists listed in Table 1 of this AD.

          This condition, if not detected and corrected, could lead to further cases of in-flight loss of the hoist
          load, possibly resulting in injury to persons on the ground or in a hoisting accident.

          To address this unsafe condition, EASA issued a series of ADs (2013-0065-E, 2013-0077-E,
          2013-0275, 2014-0201, 2014-0254, 2015-0069 and 2015-0160, each new AD superseding the
          previous one) to require identification of the installed hoist and, for affected hoist installations, a
          repetitive load check/test of the slip value of the overload clutch. Operational and environmental
          limitations as well as a periodic replacement of the overload clutch were also incorporated.

          After EASA AD 2015-0160 was published, 18 hoists were confirmed to be below limit, with 22 more
          under investigation, and it was determined that some versions of the existing overload clutch had
          not been approved at aircraft level. A new overload clutch P/N was developed with improved
          process control to mitigate some of the factors resulting in the degraded clutch performance
          observed.

          Consequently, EASA issued AD 2015-0226 (later revised), partially retaining the requirements of
          EASA AD 2015-0160, which was superseded, reducing the maximum allowable load on the hoist,
          introducing a new limitation to the applicable Rotorcraft Flight Manual (RFM) or RFM Supplement
          (RFMS) and requiring replacement of the existing overload clutch P/N(s) with new overload clutch
          P/N(s).

          Since EASA AD 2015-0226R5 was issued, AH was granted with Major Change Approvals applicable to
          AS 365 N3, AS 332 L2 and EC225 LP helicopters, and AHD was granted with Major Change Approvals
          applicable to EC135 and EC635 helicopters, for a longer replacement/overhaul interval for the
          hoists equipped with the new overload clutch P/N.
                                                                                                                                                          21.12.2021

                                                                                                                    EASA AD No.: 2015-0226R6

          For the reason described above, this AD is revised to update the hoist replacement/overhaul
          interval with the new approved data applicable to AH AS 365 N3, AS 332 L2 and EC225 LP and AHD
          EC135 and EC635 (all models) helicopters. This AD also introduces editorial changes not affecting
          the requirements.

          This AD is still considered an interim action and further AD action may follow.

          Required Action(s) and Compliance Time(s):
          Required as indicated, unless accomplished previously:

          (1)          Within 10 hoist operating cycles or 13 hoist lifts (as applicable, see Note 1 of this AD) after
                       21 November 2015 [the effective date of the original issue of this AD], determine the P/N of
                       the hoist installed on the helicopter and, if a Goodrich hoist is installed with a P/N listed in
                       Table 1 of this AD, accomplish a records check to determine whether, during any previous
                       hoist load check/test, a cable was load-tested (average of 5 pulls) at 1 500 lb [680 kg] or more.
                       If any cable is identified to have exceeded this limit during three or more hoist load
                       checks/tests, before next hoist operation, replace the affected cable with a serviceable cable.
                       If any cable is identified to have exceeded this limit during two hoist load checks/tests, before
                       the next hoist load check/test, replace the affected cable with a serviceable cable. For
                       replacement of a cable, see figure 1 (flowchart) of this AD.

                                                          Table 1 – Affected Goodrich Hoists P/N
                                                                  (all suffixes, unless specified)
                                   42315          44301-10-2          44301-10-6            44301-10-9           44311          44315
                                   42325          44301-10-4          44301-10-7           44301-10-10           44312          44316
                              44301-10-1          44301-10-5          44301-10-8           44301-10-11           44314          44318

          Note 1: Hoist operating cycles or hoist lifts are defined in the aircraft maintenance instructions.
          Whether hoist operating cycles or hoist lifts are being tracked as part of the aircraft maintenance
          instructions determines the applicable limits in this AD (cycles or lifts respectively).

          (2)          Within 30 days after 21 November 2015 [the effective date of the original issue of this AD],
                       accomplish an initial hoist load check/test in accordance with approved instructions from the
                       helicopter design approval holder, or from the hoist installation design change approval
                       holder (STC holder), as applicable to installation and helicopter type/model.

          (3)          Within the time interval, or hoist operating cycles/hoist lifts specified in the approved
                       instructions from the applicable design (change) approval holder, whichever occurs first after
                       the initial load check as required by paragraph (2) of this AD, and, thereafter, at intervals not
                       to exceed the values (calendar time, or hoist operating cycles/hoist lifts, whichever occurs
                       first) as specified in those same instructions, as applicable, accomplish a hoist load check/test
                       (see Note 1 of this AD) in accordance with the instructions for on-going testing.

          (4)          If, during any hoist load check/test as required by paragraph (2) or (3) of this AD, as
                       applicable, the hoist fails the test, deactivate the hoist and, before next hoist operation,
                       replace the hoist with a serviceable hoist, as defined in Table 2 of this AD.
                                                                                                                                                          21.12.2021

                                                               Table 2 – Serviceable Goodrich Hoists
                          A hoist having a P/N not listed in Table 1 of this AD.
                          A hoist having a P/N as listed in Table 1 of this AD, and having a serial number (s/n) with a
                          “4” as the first digit (see Note 2 of this AD), and with an overload clutch assembly which
                          has accumulated less than 24 months, or 1 200 hoist operating cycles/1 600 hoist lifts,
                          since new or since last overhaul.
                          For AW139, AB139 and AW 109SP helicopters only: A hoist having a P/N as listed in Table
                          1 of this AD, and having a s/n with a “4” as the first digit (see Note 2 of this AD), and with
                          an overload clutch assembly which has accumulated less than 36 months, or 2 600 hoist
                          lifts, since new or since last overhaul. The time interval may be extended by up to
                          4 months, but not beyond 40 months total interval. No tolerance may be applied to the
                          hoist lift limit.
                          For AS 365 N3, AS 332 L2, EC225 LP, EC135 and EC635 helicopters only:
                          A hoist having a P/N as listed in Table 1 of this AD, and having a s/n with a “4” as the first
                          digit (see Note 2 of this AD), and with an overload clutch assembly which has accumulated
                          less than 36 months, or 2 000 hoist operating cycles, since new or since last overhaul. The
                          time interval may be extended by up to 4 months, but not beyond 40 months total
                          interval. No tolerance may be applied to the hoist operating cycles limit.


          Note 2: Hoists that are equipped with a new overload clutch assembly P/N are (re)identified with a
          “4” as first digit of the s/n, e.g. 00304 becomes 40304. This modification can be done on existing
          hoists during overhaul.

          (5)          If a hoist test as required by paragraph (2) or (3) of this AD cannot be accomplished for lack of
                       approved instructions from the applicable design (change) approval holder, before next hoist
                       operation, remove or deactivate the hoist.

          (6)          If the hoist is equipped with an old overload clutch assembly P/N (see Note 2 of this AD),
                       before exceeding 1 200 hoist operating cycles / 1 600 hoist lifts accumulated since
                       04 December 2013 [the effective date of EASA AD 2013-0275], or within the compliance time
                       (as applicable) specified in Table 3 of this AD, whichever occurs first, modify the helicopter by
                       replacing the affected clutch assembly with a new overload clutch assembly P/N in
                       accordance with approved instructions from the applicable design (change) approval holder,
                       or remove or deactivate the hoist.

                       As an alternative to any replacement as required by this paragraph, it is acceptable to remove
                       or deactivate the hoist, pending installation of a replacement hoist, noting the installation
                       requirements of paragraph (8) of this AD.

          (8)          From 21 November 2016 [12 months after the effective date of the original issue of this AD], it
                       is allowed to install on any helicopter an affected Goodrich hoist, having a P/N as listed in
                       Table 1 of this AD, provided it is a serviceable hoist as defined in Table 2 of this AD. Following
                       installation, prior to hoisting operation, the hoist must pass a test as specified in paragraph (2)
                       of this AD and, thereafter, the repetitive actions required by this AD must be accomplished.

          Note 3: For the purpose of this AD, reinstallation on a helicopter of a hoist that was temporarily
          removed from that same helicopter is not considered as “installation.”

          (9)          Within 30 days after 21 November 2015 [the effective date of the original issue of this AD],
                       amend the applicable RFM(S) by including the hoist operation limitations as specified in
                       Placards 1 and 2, or 1 and 3, of this AD, as applicable, inform all flight crew members and hoist
                       operators and, thereafter, operate the helicopter accordingly.
                                                                                                                                                          21.12.2021

                       Installation of these placards, in full view of the pilot(s) and/or hoist operator, as applicable, is
                       acceptable to comply with the requirement of paragraph (9) of this AD. Alternatively,
                       insertion of revised pages that contain this same information, if included in approved
                       instructions from the applicable design (change) approval holder, into the applicable RFM(S) is
                       acceptable to comply with the requirement of paragraph (9) of this AD.

                                                            Placard 1 – Operational Limitations
                                    Operation with extended cable and load on the hook:
                                    - Maximum permissible bank angle in turn is 20°
                                    - Warning: exceeding 15° of lateral pendulum angle/helicopter vertical
                                      axis can lead to clutch slippage
                                    Caution: overload clutch is unlikely to function in case of overload


                                                       Placard 2 – For 600-lb [272 kg] rated hoists
                                             OAT above 0°C : Maximum hoist load 550 lb [249 kg]
                                             OAT at or below 0°C : Maximum hoist load 500 lb [227 kg]

          (10) Within 30 days after 21 November 2015 [the effective date of the original issue of this AD],
               amend the applicable RFM(S) by including the instructions into the Limitations Section as
               specified in Table 5 of this AD, inform all flight crew members and hoist operators and,
               thereafter, operate the helicopter accordingly.

                                                                  Table 5 – Hoist Limitation

                          A maximum of two persons at a time (with equipment) can be hoisted, except when it can
                          be explicitly determined that hoisting more persons (with equipment) does not exceed the
                          maximum hoist load, e.g. when small persons or children are being hoisted.

                       Inserting a copy of this AD into the applicable RFM(S), or revising the applicable RFM(S) with
                       pages from the applicable design (change) approval holder that contain this same information,
                       is an acceptable method to comply with the RFM(S) amendment requirement.

          (11) From 21 November 2015 [the effective date of the original issue of this AD], if a partial reel
               out occurs as described in the approved instructions from the design (change) approval
               holder, as applicable, before next flight, remove or deactivate the hoist or, before next hoist
               operation, replace the hoist with a serviceable hoist, noting the installation requirements of
               paragraph (8) of this AD.
                                                                                                                                                          21.12.2021

  Genannte Airworthiness Directives unter dieser Rubrik, die nicht durch die EASA herausgegeben worden sind,
  wurden durch die EASA über die Entscheidung Nr. 2019/018/ED übernommen und sind somit ebenfalls Airworthin-
  ess Directives der EASA.

  Anmerkungen:
  Gemäß der EU Verordnung Nr. 1321/2014, Anhang I, Teil M, Unterabschnitt C, M.A.301(f)(1), ML.A.301(d)(1),
  M.A.303 und ML.A.303 dürfen Luftfahrzeuge nach dem in der Lufttüchtigkeitsanweisung angegebenen
  Termin nur in Betrieb genommen werden, wenn die angeordneten Maßnahmen ordnungsgemäß durchge-
  führt worden sind.
  Die Europäische Agentur für Flugsicherheit (EASA) hat die oben referenzierte Lufttüchtigkeitsanweisung
  EASA AD 2020-0033R1 vom 10.12.2021 herausgegeben oder per Entscheidung Nr. 2019/018/ED übernom-
  men.
  Gemäß § 14 Abs. 2 der Betriebsordnung für Luftfahrtgerät (LuftBO) sind diese Lufttüchtigkeitsanweisun-
  gen direkt in der Bundesrepublik Deutschland gültig und bedürfen keiner Umsetzung durch das Luftfahrt-
  Bundesamt.
  Mit Hilfe dieser Übersichtsseite veröffentlicht das Luftfahrt-Bundesamt ebenfalls die über § 14 Abs. 2 direkt
  gültigen Lufttüchtigkeitsanweisungen der EASA in den Nachrichten für Luftfahrer und im Internet unter
  www2.LBA.de/LTAs/. Dieser Service dient reinen Informationszwecken und liegt keinem Verwaltungsver-
  fahren zu Grunde. Rechtsmittel sind damit ausgeschlossen.
