Airbus Helicopters
This AD applies to Airbus Helicopters Model SA330J helicopters, certificated in any category, with a left-hand (LH) or a right-hand (RH) hydraulic pump part number FR65WEO2005-175A with a serial number 4108, 4141, 4177, 4227, 4241, 4284, 4377, 4422, 4570, 4573, 4574, 4641, 4649, 4668, 4766, 4802, 4821, 4831, 4837, 4888, 4896, 4946, 4985, 5023, 5071, 5304, 5366, 5376, 5409, 5442, 5486, 5599, 5630, 94075/01, or 94048/01 installed.
The FAA is superseding Airworthiness Directive (AD) 2017-14-05 for Airbus Helicopters Model SA330J helicopters. AD 2017-14-05 required replacing certain right-hand (RH) hydraulic pumps and was prompted by reports of broken screws that attach the cover of the hydraulic pump. This new AD requires replacing certain left-hand (LH) and RH hydraulic pumps. This AD was prompted by reports of broken bolts that attach the cover of the hydraulic pump. The actions of this AD are intended to address an unsafe condition on these products.
You are responsible for performing each action required by this AD within the specified compliance time unless it has already been accomplished prior to that time.

(ii) Within 110 hours TIS from the effective date of this AD, replace the LH hydraulic pump with an airworthy hydraulic pump that is not listed in paragraph (a) of this AD.
(2) For helicopters with either a LH or RH hydraulic pump that is listed in paragraph (a) of this AD installed, within 110 hours TIS from the effective date of this AD, replace the hydraulic pump with an airworthy hydraulic pump that is not listed in paragraph (a) of this AD.
