AD/CESSNA 337/24 - Forward Engine Compartment - Self Locking Nuts - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, represent a comprehensive set of rules and guidelines designed to maintain the safety and efficiency of civil aviation within the country. One particular legislative instrument, F2006B08243, addresses the specific issue of airworthiness directives for certain Cessna aeroplane models. This legislative instrument was introduced to ensure that particular aircraft models adhere to stringent safety standards, thereby mitigating risks associated with the operation of these aircraft. The policy objective of this directive is to mandate regular inspections and maintenance of self-locking nuts in the forward engine compartment of specified Cessna 337 Series Aeroplanes, ensuring they remain airworthy and safe for operation. By setting these specific requirements, the Civil Aviation Safety Authority aims to uphold the highest safety standards in civil aviation, protecting both the public and aviation personnel.

Scope and Application

The Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998, specifically in Part 39 - 105, applies to all Cessna 337 series aeroplanes with specific serial numbers: models 337 with serial numbers 33701672 to 33701748 and models P337 with serial numbers P3370226 to P3370257. This regulation mandates an inspection of the forward engine compartment for self-locking nuts, as detailed in AD/CESSNA 337/24 10/77, ensuring the aircraft's airworthiness. Compliance with this directive is required within 100 hours of time in service after 31 October 1977. The scope of this regulation extends across the Commonwealth of Australia, impacting the aviation industry by imposing specific maintenance requirements on these aircraft models to enhance safety and operational standards. There are no exclusions or exemptions outlined in the regulation, which applies directly to the specified serial numbers of the Cessna 337 series aeroplanes.

Key Provisions

The Civil Aviation Regulations 1998, under PART 39 - 105, specifically address the Airworthiness Directives for Cessna 337 Series Aeroplanes, with AD/CESSNA 337/24 focusing on the inspection of self-locking nuts in the forward engine compartment. According to section 10/77, this directive applies to all Cessna 337 models with serial numbers ranging from 33701672 to 33701748 and all P337 models with serial numbers from P3370226 to P3370257. The directive mandates a thorough inspection of the forward engine compartment's self-locking nuts to ensure compliance with safety standards. This requirement is outlined in section 10/77 of the document, specifically referencing Cessna SL ME77-18 Item No. 1. The obligations imposed by this directive on the parties involved are clear and specific. Operators of the affected Cessna 337 and P337 models must ensure that the inspection of the forward engine compartment's self-locking nuts is conducted within 100 hours of time in service after 31 October 1977. This requirement is crucial for maintaining the airworthiness of the aircraft and ensuring compliance with safety regulations. Operators must document the inspection and any subsequent actions taken in accordance with the directive. Furthermore, aircraft maintenance personnel responsible for conducting the inspection must be adequately trained and authorised to perform these tasks. Failure to comply with the requirements of AD/CESSNA 337/24 may result in significant consequences. Section 10/77 of the Civil Aviation Regulations 1998 outlines the potential penalties and consequences for non-compliance. In cases of breach, the Civil Aviation Safety Authority (CASA) has the authority to take enforcement actions, which may include imposing fines, ordering corrective actions, or even grounding the aircraft until compliance is achieved. The specific penalties for non-compliance are not explicitly stated in the document but generally align with the regulatory framework of the Civil Aviation Regulations 1998, which can include substantial fines and other regulatory sanctions. The severity of the consequences underscores the importance of adhering to the stipulated safety directives to maintain the safety and airworthiness of the aircraft.
