Overview
The Civil Aviation Safety Regulations 1998, which were enacted to ensure the safety of civil aviation operations in Australia, have been amended through an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA). The AD in question, AD/CESSNA 400/52 Amdt 2, pertains to the inspection of trim control systems in all models of Cessna 401, 402, 404, 411, 414, and 421 series aircraft. This amendment was introduced to rectify an error in the previous AD, Amendment 1, which had inadvertently allowed the inspection interval to be extended beyond the intended timeframe. By issuing Amendment 2, CASA has re-established the inspection requirement to a maximum interval of 120 hours, ensuring that the safety checks are performed in a timely manner and aligning with the overall objective of maintaining airworthiness standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, apply to all aircraft and aeronautical products within the Commonwealth of Australia. This particular Airworthiness Directive (AD) AD/CESSNA 400/52 Amdt 2 pertains to all models of the Cessna 400 series aeroplanes, namely the Cessna 401, 402, 404, 411, 414, and 421. The directive mandates a specific inspection of the trim control systems as outlined in the Cessna SL ME77-34 Supplement 1, dated February 13, 1978. This inspection must be conducted at intervals not exceeding 120 hours of time in service, ensuring that the aircraft remains airworthy and compliant with safety regulations. The AD is effective from 8 July 2004, superseding Amendment 1 that was issued on 30 January 2004 and subsequently corrected by this amendment to ensure timely inspections. The AD is enforced by the Civil Aviation Safety Authority (CASA) and its delegate, with the intent to correct an unsafe condition identified in the trim control systems of the specified aircraft models.
Key Provisions
The Airworthiness Directive (AD) AD/CESSNA 400/52 Amdt 2 pertains to specific models of Cessna 400 series aeroplanes, including Cessna 401, 402, 404, 411, 414, and 421. This directive is issued under the authority of the Civil Aviation Safety Regulations 1998, specifically section 39.1(1) (section 39.1(1)). The AD mandates that the specified action, outlined in the requirement section, must be taken to address the identified unsafe condition. This requirement is applicable in the circumstances and according to the instructions detailed in the requirement section, and must be completed within the timeframe mentioned in the compliance section.
This AD imposes specific obligations on the operators of the affected Cessna 400 series aircraft. Primarily, it requires these operators to inspect the trim control systems of their aircraft at intervals not exceeding 120 hours of time in service. The inspection must adhere to the instructions provided in Cessna SL ME77-34 Supplement 1, dated February 13, 1978. This directive aims to ensure that the trim control systems are functioning correctly and safely, thereby maintaining the airworthiness of the aircraft.
The AD does not explicitly detail offences, penalties, or consequences for non-compliance within the text provided. However, it is implied that failure to adhere to the requirements of this Airworthiness Directive could result in the aircraft being deemed unairworthy. This non-compliance could lead to grounding of the aircraft, enforcement actions by the Civil Aviation Safety Authority, and potential legal ramifications for the operators. The specific penalties or civil/criminal consequences for breach would be governed by the broader provisions of the Civil Aviation Safety Regulations 1998 and any applicable aviation safety laws.
