The Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by: 0 a. Removing Airworthiness Directive (AD) 2019-03-12, Amendment 39-19564 (84 FR 8250, March 7, 2019); and 0 b. Adding the following new AD: \n\n2021-10-03 Airbus Helicopters: Amendment 39-21536; Docket No. FAA- 2021-0020; Project Identifier MCAI-2020-01639-R. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) is effective June 22, 2021. \n\n(b) Affected ADs \n\n\n\tThis AD replaces AD 2019-03-12, Amendment 39-19564 (84 FR 8250, March 7, 2019) (AD 2019-03-12). \n\n(c) Applicability \n\n\n\tThis AD applies to Airbus Helicopters Model EC225LP helicopters, all manufacturer serial numbers, certificated in any category, equipped with emergency life rafts installed in the multi-purpose sponsons. \n\n(d) Subject \n\n\n\tJoint Aircraft System Component (JASC) Code 2564, Life Raft. \n\n(e) Reason \n\n\n\tThis AD was prompted by reports of jammed bellcranks in the life raft inflation cylinder percussion system. The FAA is issuing this AD to address jammed bellcranks in the life raft jettison inflation cylinder percussion system. This condition could result in failure of a life raft to release in an emergency and subsequent injury to occupants. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Definitions \n\n\n\tFor the purposes of this AD, the definitions specified in paragraphs (g)(1) through (4) of this AD apply. \n\t(1) Group 1: Helicopters that have an affected part installed. \n\n((Page 26833)) \n\n\n\t(2) Group 2: Helicopters that do not have an affected part installed. A helicopter that embodies Airbus Helicopters Modification 07 28457 inproduction is a Group 2 helicopter, provided the helicopter remains in that configuration. \n\t(3) Affected part: Life raft release bell cranks part number (P/ N) 332A41-4396-20 (left-hand (LH) side) and P/N 332A41-4396-21 (right-hand (RH) side). \n\t(4) Serviceable part: Life raft release bell cranks P/N 332A41- 4396-22 (LH) and P/N 332A41-4396-23 (RH). \n\n(h) Retained Repetitive Actions, With Specified Helicopter Group and New Note \n\n\n\tThis paragraph restates the requirements of paragraph (e) of AD 2019-03-12, with a specified helicopter group and new Note 1. For Group 1: Before further flight, and thereafter at intervals not to exceed 6 months: \n\t(1) Clean each bellcrank and pivot link and inspect each bellcrank hole for corrosion. If there is any corrosion in a bellcrank hole: \n\t(i) Remove the corrosion without exceeding a maximum depth of 0.1 millimeter (0.004 inch). \n\t(ii) Clean each pivot link using 400-grain abrasive paper. \n\t(iii) Apply corrosion protectant (Alodine 1200 or equivalent) to each bellcrank hole. \n\t(2) Lubricate each bellcrank hole with grease before assembling the bellcrank. \n\n\n\tNote 1 to paragraph (h): Airbus Helicopters Emergency Alert Service Bulletin No. 05A050, Revision 0, dated July 22, 2016; and Airbus Helicopters Emergency Alert Service Bulletin No. 05A050, Revision 1, dated April 3, 2019; specify procedures for cleaning and lubricating each bellcrank and pivot link of the life raft inflation cylinder percussion system and removing any corrosion. \n\n(i) New Requirement of This AD: Bellcrank Replacement \n\n\n\tFor Group 1: Within 6 months after the effective date of this AD, or before the next operation over water, whichever occurs first, replace each affected bellcrank with a serviceable part, as defined in paragraph (g)(4) of this AD, in accordance with Paragraph 3.B.2. of the Accomplishment Instructions of Airbus Helicopters Alert Service Bulletin EC225-25A211, Revision 1, dated October 23, 2019; except where the serviceinformation specifies to remove and scrap certain parts, this AD requires removing those parts from service instead. \n\n(j) Terminating Action for Repetitive Actions Required by Paragraph (h) of This AD \n\n\n\tAccomplishment of the bellcrank replacement required by paragraph (i) of this AD is terminating action for the repetitive actions required by paragraph (h) of this AD for that helicopter only. \n\n(k) Parts Installation Limitation \n\n\n\t(1) For Group 1: After the replacement required by paragraph (i) of this AD is done, only a serviceable part, as defined in paragraph (g)(4) of this AD, is allowed to be installed on that helicopter. \n\t(2) For Group 2: As of the effective date of this AD, only a serviceable part, as defined in paragraph (g)(4) of this AD, is allowed to be installed on any helicopter. \n\n(l) Special Flight Permit \n\n\n\tSpecial flight permits, as described in 14 CFR 21.197 and 21.199, are not allowed. \n\n(m) Alternative Methods of Compliance (AMOCs) \n\n\n\t(1)The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
