AD/AC/54 - Aileron Trim Tab - Inspection and Repair

Overview

The Civil Aviation Regulations 1998, as amended, is a crucial piece of legislation designed to regulate civil aviation within Australia, ensuring safety and efficiency across the industry. Enacted by the Parliament of Australia, these regulations are overseen by the Civil Aviation Safety Authority (CASA) and aim to address gaps in the oversight of civil aviation operations, including the maintenance and airworthiness of aircraft. The regulations are updated regularly to incorporate new technological advancements and address emerging safety concerns. One particular legislative instrument under this regulation, F2006B02114, pertains to the airworthiness directives for specific models of Twin Commander aeroplanes, requiring inspections and repairs to the aileron trim tabs to ensure ongoing compliance with safety standards. This legislative instrument, F2006B02114, specifically addresses the inspection and repair of aileron trim tabs on Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) series aeroplanes, particularly models 690, 690A, and 685 with certain serial numbers. The directive mandates that these inspections and repairs be carried out within 100 hours of time in service after 30 November 1973, ensuring that these aircraft meet the required safety standards and remain airworthy. This targeted approach under the broader Civil Aviation Regulations 1998 aims to enhance aircraft safety by addressing specific structural issues that could potentially compromise the aircraft's operational integrity.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to certain models of Twin Commander (Gulfstream/Rockwell/ Aerocommander 500, 600 and 700) series aeroplanes, as detailed in the Airworthiness Directives. The directive in question pertains to the inspection and repair of the aileron trim tab, as outlined in AD/AC/54 11/73. This regulation applies to all model 690 and 690A aircraft with serial numbers (S/Nos.) ranging from 11001 to 11127, and all model 685 aircraft with specific S/Nos. including 12002, 12003, 12009, 12011, 12018, 12019, 12021, and 12031. Compliance with these directives is mandated within 100 hours of time in service after 30 November 1973. The directive references Aero Commander Service Bulletin No. 127 for further guidance. This regulation falls under the jurisdiction of the Commonwealth of Australia, administered by the Civil Aviation Safety Authority (CASA). The scope of this legislation is precise, focusing on specific models and serial numbers of aircraft, ensuring adherence to safety standards set forth by CASA.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contains provisions related to airworthiness directives for certain aircraft models, including the Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) series aeroplanes. Section 39-105 details a specific airworthiness directive for the inspection and repair of aileron trim tabs on these aircraft models (AD/AC/54). This directive applies to all model 690 and 690A aircraft with serial numbers (S/Nos.) ranging from 11001 to 11127, and all model 685 aircraft with S/Nos. 12002, 12003, 12009, 12011, 12018, 12019, 12021, and 12031. The directive mandates that this inspection and repair must be carried out within 100 hours of time in service after 30 November 1973, as detailed in Aero Commander Service Bulletin No. 127. The obligations imposed by this airworthiness directive require aircraft operators and maintenance personnel to ensure that the specified aileron trim tab inspections and repairs are performed on the applicable aircraft models within the stipulated timeframe. Compliance with this directive is critical to maintaining the airworthiness of the aircraft, ensuring the safety of passengers and crew, and meeting regulatory standards set by the Civil Aviation Safety Authority (CASA). Failure to adhere to this directive could result in the aircraft being deemed unairworthy, leading to potential grounding and other regulatory actions. In terms of enforcement and consequences, non-compliance with the airworthiness directive can result in significant legal and financial repercussions. The Civil Aviation Regulations 1998 outline that violations of such directives may be subject to penalties under section 35 of the Civil Aviation Act 1988. The potential penalties for non-compliance with airworthiness directives can include substantial fines, both civil and criminal, depending on the severity and impact of the non-compliance. For instance, in civil proceedings, penalties can include fines up to a maximum of $210,000 for individuals and $1,050,000 for corporations, as stipulated in the applicable legislation. In criminal proceedings, the penalties can be even more severe, with potential imprisonment terms for those found guilty of serious non-compliance that endangers safety.
