Airworthiness Directive · Amendment 39-23036 · Electrical connectors
Airbus Helicopters
This AD applies to Airbus Helicopters Model EC225LP helicopters, certificated in any category, as identified in European Union Aviation Safety Agency AD 2023-0030, dated February 2, 2023 (EASA AD 2023-0030).
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model EC225LP helicopters. This AD was prompted by the identification of missing electrical bonding on a certain part-numbered additional and optional search light (search light). This AD requires installing an electrical bonding braid modification. These actions are specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2023-0030.
Note 1 to paragraph (g): Appendix 4 of Airbus Helicopters Alert Service Bulletin No. EC225-33A018, dated December 15, 2023, which is referenced in EASA AD 2023-0030, identifies helicopter configurations (right-hand column of the table) by helicopter serial number (left-hand column of the table).
(1) Where EASA AD 2023-0030 requires compliance in terms of flight hours, this AD requires using hours time-in-service.
(2) Where EASA AD 2023-0030 refers to its effective date, this AD requires using the effective date of this AD.
(3) Where Note 1 of EASA AD 2023-0030 specifies that a tolerance of +10% may be applied to the calendar compliance time specified in paragraph (1) of EASA AD 2023-0030, this AD does not allow that tolerance.
(4) Where the material referenced in EASA AD 2023-0030 specifies discarding parts, this AD requires removing those parts from service.
(5) This AD requires replacing text as specified in paragraphs (h)(5)(i) though (v) of this AD.
(i) Where the material referenced in EASA AD 2023-0030 specifies to “do the electrical bonding”, this AD requires replacing that text with “install the electrical bonding braid”.
(ii) Where the material referenced in EASA AD 2023-0030 specifies to “bond the labels `741VN' and `742VN' of the set of labels (8) as close as possible from the equipment (SECTION A-A and B-B)”, this AD requires replacing that text with “apply labels `741VN' and `742VN' of the set of labels (8) directly adjacent to the grounding point as depicted in Figure 6, Section A-A and Section B-B”.
(iii) Where the material referenced in EASA AD 2023-0030 specifies to “remove and keep” this AD requires replacing that text with “remove”.
(iv) Where the material referenced in EASA AD 2023-0030 specifies to “locate the hole (A) in accordance to the position”, this AD requires replacing that text with “determine the position of hole (A) in Figure 4, Detail B”.
(v) Where the material referenced in EASA AD 2023-0030 specifies to paint strip the hole on “the both face”, this AD requires replacing that text with “each side”.
(6) Where the material referenced in EASA AD 2023-0030 specifies to do a continuity test, if the insulation resistance value is 8 or more ohms as a result of the continuity test, this AD requires, before further flight, accomplishing corrective action in accordance with a method approved by the Manager, International Validation Branch, FAA; or EASA; or Airbus Helicopters' EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
(7) This AD does not adopt the “Remarks” section of EASA AD 2023-0030.
Although the material referenced in EASA AD 2023-0030 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
