Overview
The Airworthiness Directive (AD) AD/A330/12 Amendment 1, issued by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Safety Regulations 1998, was enacted to address an unsafe condition related to the Ram Air Turbine (RAT) rotary solenoids in certain Airbus A330 series aircraft. Specifically, this AD was introduced to ensure the proper deployment of the RAT in emergency situations, a critical safety measure for aircraft operation. This amendment to the original directive extends its applicability to include additional A330 models, namely the -302 and -303, thereby enhancing the overall safety of the affected aircraft fleet. The directive mandates that specific actions be taken, such as identifying the serial number of the RAT actuator and inspecting the position of the rotary solenoids if necessary, according to detailed instructions provided in Airbus Service Bulletin A330-29-3083 or later revisions approved by the French DGAC.
Scope and Application
The Airworthiness Directive (AD) AD/A330/12 Amdt 1 applies specifically to the Airbus Industrie A330 series aeroplanes, encompassing models -201, -202, -203, -223, -243, -301, -302, -303, -321, -322, -323, -341, -342 and -343, all serial numbers, that are fitted with a specific Ram Air Turbine (RAT) module, model ERPS06M, with part numbers 766351, 768084, 770379, 770952, or 770952A, and containing a RAT actuator with part numbers 5911905, 5911326, or 5913234, all serial numbers. The directive requires actions to be taken to ensure the safe operation of the aircraft, particularly focusing on the deployment of the RAT in emergency situations. The directive, issued under the authority of the Civil Aviation Safety Authority (CASA), is applicable throughout the Commonwealth of Australia and mandates inspections and corrective measures as specified, unless such actions have already been completed prior to the effective date of the directive, which is 30 September 2004.
Key Provisions
The Airworthiness Directive (AD) AD/A330/12 Amdt 1 pertains to the Airbus A330 series aeroplanes and mandates specific actions to address a potential unsafe condition related to the Ram Air Turbine (RAT) rotary solenoids. The AD requires that certain actions be taken in relation to the specified aircraft models and serial numbers, which are all Airbus A330 aircraft fitted with the RAT module and specific part numbers (sections 1 and 2). The actions include identifying the serial number of the affected actuator and inspecting the rotary solenoids if necessary (section 3).
This AD imposes obligations on the owners and operators of the specified Airbus A330 aircraft. They must identify the serial number of the affected actuator as per the instructions in AIRBUS Service Bulletin (SB) A330-29-3083 or later revisions approved by the French DGAC (section 1). If the actuator serial number is greater than 1286, no inspection is required (section 2). However, if the serial number is 1286 or less, the position of the rotary solenoids must be inspected, and corrective measures must be taken if necessary, following the instructions in the aforementioned AIRBUS SB (section 3).
Failure to comply with the requirements of this AD may result in serious safety implications. The AD specifies that any non-compliance must be addressed unless the required actions have already been completed prior to the compliance date of 30 September 2004 (section 4). The AD became effective on the same date, 30 September 2004, and its non-compliance could potentially lead to safety hazards or regulatory penalties, although specific penalties are not outlined in the AD itself.
