AD/CESSNA 310/8 - Main Landing Gear Side Brace Link - Inspection

Overview

The Civil Aviation Regulations 1998, under Part 39 – 105, is an integral part of the Australian legislative framework designed to ensure the safety and airworthiness of aircraft. This particular legislative instrument, F2006B08187, was enacted to address the specific safety concerns related to the main landing gear side NKBrace link of Cessna 310 series aeroplanes, particularly those prior to serial number 35550. The Act was introduced to ensure that these aircraft meet stringent safety standards, thereby preventing potential mechanical failures and ensuring the safety of passengers and crew. This legislative instrument is overseen by the Civil Aviation Safety Authority, with a clear policy objective of maintaining the highest possible safety standards in civil aviation. The enactment by the Commonwealth Parliament underscores the importance of this regulation in the national aviation safety regime.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Civil Aviation Safety Authority’s (CASA) schedule of airworthiness directives which are imperative for maintaining the safety standards of aircraft operating in Australia. The directive AD/CESSNA 310/8 pertains to all Cessna 310 and 310B series aeroplanes that are prior to serial number 35550 and are fitted with an early style link for the main landing gear side NKBrace. This regulation applies to all aircraft operators who must adhere to the compliance requirement of inspecting the main landing gear side NKBrace link at intervals not exceeding 100 hours of time in service. The directive applies across the Commonwealth of Australia, ensuring that all aircraft within its jurisdiction maintain these safety standards. There are no stated exclusions or exemptions within the scope of this directive, and it is enforceable through the regulatory framework established by CASA. Additionally, the Civil Aviation Regulations 1998 allow for the extension or restriction of application of such directives through subordinate instruments. This means that CASA may issue further detailed instructions or modifications to the original directive to better address specific safety concerns or to adapt to technological advancements and operational changes. The overarching objective of these regulations is to maintain the highest standards of aviation safety in Australia, thereby protecting the public and ensuring the integrity of civil aviation operations.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, details the Civil Aviation Safety Authority’s (CASA) schedule of airworthiness directives, which mandate specific actions to ensure the continued airworthiness of aircraft. In the case of Cessna 310 Series Aeroplanes, AD/CESSNA 310/8 pertains to the main landing gear side NKBrace Link. This directive applies to all model 310 and 310B prior to Serial Number 35550 that are fitted with the early style link. The compliance requirement is that inspections of the main landing gear side NKBrace Link must be conducted at intervals not exceeding 100 hours of time in service (Regulation 39.105(1)(a)). The obligations imposed by this directive on the aircraft owners or operators include ensuring that the specified inspections are performed by appropriately qualified personnel in accordance with the outlined intervals. This involves adhering to the procedures set forth in Cessna Service Letter No. 310-34, which provides detailed guidance on how to conduct the inspections. It is imperative that these inspections are logged in the aircraft's maintenance records to demonstrate compliance with the regulatory requirements (Regulation 39.105(2)). Failure to comply with the airworthiness directive can result in significant consequences. CASA may take enforcement action against the aircraft owner or operator, including the potential grounding of the aircraft until the required inspections are completed and certified. In terms of penalties, non-compliance can lead to substantial fines. Under the Civil Aviation Act 1988, the maximum penalty for contravening an airworthiness directive can include fines of up to $222,200 for individual offenders and $1,111,100 for corporate offenders, along with other potential civil or criminal sanctions as deemed appropriate by the court (Civil Aviation Act 1988, Section 90). These measures underscore the importance of strict adherence to CASA’s airworthiness directives to ensure the safety and continued airworthiness of the aircraft.
