AD/CESSNA 310/2 - Outboard Aileron Hinge - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, address the overarching safety and regulatory framework for civil aviation in Australia, including the oversight of airworthiness directives. Within this framework, the Civil Aviation Safety Authority (CASA) issues specific directives to ensure the safe operation of aircraft. One such directive is AD/CESSNA 310/2, which pertains to the inspection of outboard aileron hinges on Cessna 310 Series aeroplanes. This directive was introduced to mitigate risks associated with the structural integrity of the aileron hinges, particularly in older models of the aircraft, thereby enhancing flight safety and compliance with international standards. The policy objective of this directive is to ensure that the aircraft maintain their airworthiness and adhere to the stringent safety standards set forth by CASA, reflecting a commitment to the highest levels of aviation safety within Australia.

Scope and Application

The Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998, specifically within Part 39, has issued Airworthiness Directives concerning the Cessna 310 series aeroplanes. These directives are designed to ensure the safety and airworthiness of the aircraft, specifically targeting model 310 aircraft with serial numbers prior to 35392, with the exception of those equipped with certain outboard aileron hinges. The inspection requirements outlined in Airworthiness Directive AD/CESSNA 310/2 mandate that these aircraft undergo inspections at intervals not exceeding 100 hours of time in service to maintain compliance. The directive references Cessna Service Letter No. 310-7 and FAA AD 57-4-1 as the basis for these inspection protocols. This legislation applies to all relevant aircraft operators and maintenance personnel within Australia, ensuring adherence to safety standards set by both Australian and international aviation authorities. The applicability of this directive extends to any person or entity operating the specified Cessna 310 series aeroplanes within Australian airspace, thereby ensuring uniform safety standards across the industry. The regulatory reach is national, overseen by CASA, which is the Commonwealth authority responsible for enforcing these regulations. There are no explicit exclusions or exemptions mentioned in the directive itself, though the specified exclusion of aircraft with certain hinge parts implies a limited scope of application. The application of these regulations may be further detailed or extended through subordinate instruments or notices issued by CASA, which may provide additional guidance or clarification on compliance and enforcement.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39, which deals with the Civil Aviation Safety Authority’s (CASA) schedule of airworthiness directives, includes specific regulations for certain aircraft models. Section 39-105 focuses on the Cessna 310 series aeroplanes and mandates the inspection of outboard aileron hinges, as outlined in AD/CESSNA 310/2. This directive applies to all model 310 Cessna aeroplanes prior to serial number 35392, except for those models that already have hinges with part numbers 0824006-1 and -2 installed. This requirement is to ensure the continued airworthiness and safety of these aircraft. Under these regulations, the specific obligations for aircraft operators and maintenance personnel include conducting inspections of the outboard aileron hinges as detailed in either Cessna Service Letter No. 310-7 or the Federal Aviation Administration’s (FAA) AD 57-4-1. Operators must ensure these inspections are carried out at intervals not exceeding 100 hours of time in service, which translates to regular and frequent checks to maintain the structural integrity of the ailerons. This regular inspection schedule is crucial to prevent potential failure of the aileron hinges, which could lead to significant safety risks during flight. Failure to comply with these airworthiness directives and the prescribed inspection intervals can result in serious consequences. Non-compliance may lead to enforcement actions under the Civil Aviation Act 1988 and the Civil Aviation Regulations 1998. The potential penalties for not adhering to these safety directives include substantial fines and, in severe cases, the grounding of the aircraft until the required inspections and necessary repairs are completed. The exact penalties can vary based on the severity of the breach and the impact on aviation safety, but they are designed to enforce strict adherence to safety standards.
