(e) UNSAFE CONDITION

    This AD was prompted by reports of incorrect installation of the motor
    (MTR) cables and the bonding braids  connected  to the engine fire ex-
    tinguisher bottles.  The FAA is issuing this AD  to detect and correct
    incorrect installation of the MTR cables and the bonding braids to the
    engine fire extinguisher bottles, which could lead to reduced perform-
    ance of the engine fire extinguishing system during an engine fire and
    consequent loss of control of the helicopter.

(f) COMPLIANCE

    Comply with this AD within the compliance times specified, unless al-
    ready done.

(g) REQUIREMENTS

    Except as specified in paragraphs (h) and (i) of this AD:  Comply with
    all required actions and compliance times specified in, and in accord-
    ance with,  European Union Aviation Safety Agency AD 2024-0193,  dated
    October 11, 2024 (EASA AD 2024-0193).

(h) EXCEPTIONS TO EASA AD 2024-0193

(1) Where EASA AD 2024-0193  requires compliance in terms of flight hours,
    this AD requires using hours time-in-service.

(2) Where EASA AD 2024-0193 refers to its effective date, this AD requires
    using the effective date of this AD.

(3) Where paragraph (2) of  EASA  AD 2024-0193  states  "any discrepancy,"
    this AD requires replacing that text with "an improper installation."

(4) This AD does not adopt the "Remarks" section of EASA AD 2024-0193.

(i) NO REPORTING REQUIREMENT

    Although the material referenced in  EASA  AD 2024-0193  specifies  to
    submit certain information  to the manufacturer,  this AD does not re-
    quire that action.

    to approve AMOCs for this AD,  if requested using the procedures found
