The above AD is notified in the Commonwealth of Australia Gazette on 19 April 2000.
Overview
The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, serve to regulate various aspects of civil aviation safety, ensuring that aircraft and aeronautical products meet certain safety standards. Part 39, in particular, addresses specific airworthiness directives that must be followed to maintain the safety of aircraft in operation. One such directive is the Airworthiness Directive for the Israel Aircraft Industries 1123 and 1124 (Westwind) Series Aeroplanes, which was introduced to address a safety concern identified with the ailerons of these aircraft models. This directive was issued by Bernard Malcolm Hole, a delegate of the Civil Aviation Safety Authority, and it became effective on 18 May 2000. The directive mandates that a radiographic inspection of the aileron rib to spar connections be conducted in accordance with specific instructions to ensure that the aircraft remain airworthy and safe for operation.
Scope and Application
The Civil Aviation Regulations 1998, specifically under Part 39 and Section 105, govern the airworthiness of aircraft in Australia, including the Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA). The particular Airworthiness Directive AD/IAI-W/20 issued under this regulation applies to specific models of Israel Aircraft Industries (IAI) 1124 and 1124A series aeroplanes, with serial numbers 297, 304, and 400 to 410, with a specific requirement for aileron inspection. This directive applies to aircraft registered in Australia, ensuring that the aircraft meet the necessary safety standards. The directive is effective as of 18 May 2000 and mandates that a radiographic inspection of the aileron be conducted in accordance with IAI Westwind Alert SB 1124-27A-145 within 200 hours of time in service following the directive’s effective date. Any exclusions or exemptions are not specified in this particular directive, and compliance is mandatory for the specified aircraft.
This Airworthiness Directive is applicable nationally, extending across all states and territories within the Commonwealth of Australia. It is enforced through CASA's authority under the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998, which empower CASA to issue such directives to ensure the continued safety of civil aviation. The directive is specific to the identified aircraft models and serial numbers, highlighting CASA's focus on targeted safety measures based on identified risks. Subordinate instruments may further define or refine the requirements or applicability of this directive, ensuring it is updated in line with ongoing safety assessments and technological advancements.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes an Airworthiness Directive (AD) issued under subregulation 39.1(1) for Israel Aircraft Industries (IAI) 1123 and 1124 (Westwind) Series Aeroplanes (subsection 39.1). This AD, AD/IAI-W/20, mandates a radiographic inspection of specific aileron components in certain models of Westwind aircraft. The directive applies to models 1124 and 1124A with serial numbers 297, 304, and the range 400 to 410, with a particular note for serial number 405's right-hand aileron (subsection 105.1(1)(a)). The inspection must be conducted according to IAI Westwind Alert Service Bulletin (SB) 1124-27A-145 (subsection 105.1(1)(b)). This inspection is required within 200 hours of time in service after the effective date of the directive, which is 18 May 2000 (subsection 105.1(1)(c)). The directive references an earlier Israeli AD No. 57-00-02-06 and was notified in the Commonwealth of Australia Gazette on 19 April 2000 (subsection 105.1(1)(d) and (e)).
Under the AD, the obligations for the relevant aircraft owners or operators include ensuring that the specified models undergo the mandated aileron inspection within the stipulated timeframe. This involves utilising the inspection procedure outlined in the IAI Westwind Alert SB 1124-27A-145, which likely includes detailed steps for radiographic examination and any required maintenance actions. The aircraft must be grounded for inspection if it has reached the 200-hour service mark post the directive's effective date. Proper documentation of the inspection and any remedial actions taken must be maintained to comply with the AD's requirements.
Failure to comply with the AD could result in the aircraft being deemed unairworthy, potentially leading to enforcement actions by the Civil Aviation Safety Authority (CASA). The consequences of not adhering to the AD can include penalties imposed under the Civil Aviation Act 1988, which may encompass fines and potential prosecution. The exact penalties would depend on the specific breach and its impact on aviation safety, but the directive clearly aims to ensure that any safety issues identified are rectified promptly to maintain the highest standards of airworthiness.
