Leonardo S.p.a Helicopters
This AD applies to Leonardo S.p.a. Model A109A, A109A II, A109C, A109E, A109K2, A109S, and AW109SP helicopters, certificated in any category, with a rotor brake kit identified in European Union Aviation Safety Agency (EASA) AD 2021-0067, dated March 9, 2021 (EASA AD 2021-0067).
The FAA is adopting a new airworthiness directive (AD) for certain Leonardo S.p.a. Model A109A, A109A II, A109C, A109E, A109K2, A109S, and AW109SP helicopters, having a certain rotor brake kit installed. This AD was prompted by a report of un-commanded activation of the rotor brake system before take-off due to a jammed rotor brake control cable and subsequent partially open brake control valve. This AD requires repetitive inspections of the rotor brake control cable and replacement of the rotor brake control cable, if necessary, as 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 paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, EASA AD 2021-0067.
(1) Where EASA AD 2021-0067 requires compliance from its effective date, this AD requires using the effective date of this AD.
(2) This AD does not require the “Remarks” section of EASA AD 2021-0067.
(3) Where EASA AD 2021-0067 requires compliance in terms of flight hours (FH), this AD requires using hours time-in-service.
(4) Where paragraph (2) of EASA AD 2021-0067 requires replacing the affected part if any defect is found, for purposes of this AD, a defect also includes compromised integrity of the control cable strands (e.g., fraying or a kink).
(5) Where the service information required by EASA AD 2021-0067 specifies replacing the affected part if any damage is found, for purposes of this AD, damage includes clicks or breakings when the rotor brake lever is moved forward and backward.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
