AD/CESSNA 185/12 - Engine Mount

Overview

The Civil Aviation Regulations 1998, under Part 39, specifically address airworthiness directives to ensure the safety of aircraft in Australia. Enacted by the Commonwealth of Australia, these regulations aim to mitigate risks associated with the operation of aircraft by enforcing strict compliance with safety standards. This particular regulation, F2006B05102, targets Cessna 185 Series Aeroplanes by requiring visual inspections of the engine mount to detect any signs of cracking, particularly around the rear engine bearers and rear cross tube. The objective is to maintain the structural integrity of the aircraft and prevent potential failures that could compromise flight safety. The compliance requirement mandates that these inspections occur at intervals not exceeding 100 hours of service time, ensuring that the aircraft remains in a safe and airworthy condition.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's schedule of airworthiness directives, addressing the maintenance and safety standards for aircraft in Australian airspace. This legislation applies to all models of Cessna 185 Series aeroplanes registered within the Commonwealth of Australia, imposing mandatory safety requirements aimed at ensuring the continued airworthiness of these aircraft. The regulation mandates a visual inspection of the engine mount for signs of cracking, with a specific emphasis on the rear engine bearers and rear cross tube, to be conducted at intervals not exceeding 100 hours of time in service. This regulation's scope encompasses all entities operating Cessna 185 Series aeroplanes in Australia, ensuring compliance with the specified safety standards to maintain operational integrity and passenger safety. The legislation does not explicitly outline exclusions or exemptions, and compliance is enforced through the broader framework of the Civil Aviation Regulations 1998.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the requirements for maintaining airworthiness of various aircraft types, including the Cessna 185 Series Aeroplanes. Section AD/CESSNA 185/12 mandates that all Cessna 185 Series Aeroplanes must undergo a visual inspection of the engine mount for any signs of cracking, with a particular focus on the rear engine bearers and rear cross tube. This requirement applies universally across all models of the Cessna 185 Series (Section AD/CESSNA 185/12). The compliance interval is set at intervals not exceeding 100 hours of time in service, ensuring that the inspection is conducted regularly to maintain the integrity of the engine mount. The Act imposes specific obligations on the operators and owners of the Cessna 185 Series Aeroplanes to ensure that the engine mounts are inspected according to the outlined schedule. Operators must implement and adhere to a maintenance program that includes these inspections as a critical component. This ensures that the aircraft remains airworthy and compliant with the safety standards set forth by the Civil Aviation Safety Authority (CASA). The regulations require meticulous documentation of each inspection, including the findings and any corrective actions taken, if necessary. Breaching the requirements set forth in these regulations can lead to serious consequences. Non-compliance may result in the aircraft being grounded until the necessary inspections and repairs are completed. Additionally, the Act provides for enforcement actions by CASA, which may include fines or other penalties for repeated or severe breaches. The maximum penalties are not explicitly detailed in the provided text but are generally aligned with the severity of the non-compliance and its impact on aviation safety. Civil penalties may be imposed for less severe infractions, while more severe breaches may lead to criminal charges, particularly if they contribute to safety hazards or accidents.
