AD/CESSNA 188/25 Amdt 1 - Engine Air Inlet Duct

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form a comprehensive framework designed to ensure the safety and efficiency of civil aviation within the nation. Within this extensive regulation, Part 39 - 105 specifically addresses the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, which aims to maintain the airworthiness of aircraft by issuing mandatory safety directives. The policy objective is to ensure that all aircraft meet stringent safety standards, thereby protecting passengers, crew, and the public. One such directive, AD/CESSNA 188/25 Amendment 1, pertains to Cessna 188 (Agwagon) Series Aeroplanes, focusing on the engine air inlet duct. This directive was introduced to address a specific safety concern related to the engine air inlet duct of certain model A188 and A188B aircraft, mandating compliance within 50 hours of time in service after 12 May 1975 to rectify identified safety issues.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, issued under the authority of the Civil Aviation Safety Authority, outlines the airworthiness directives applicable to the Cessna 188 (Agwagon) Series Aeroplanes. This legislation applies to all model A188 and A188B aeroplanes with serial numbers ranging from 18800833 to 18801824, inclusive of those with a suffix "T". The directive mandates that these aircraft must comply with either Cessna Service Letter SE75-5 or SE74-23, referencing FAA Airworthiness Directives 74-23-07 and 75-09-06. Compliance with these directives is required within 50 hours of time in service after 12 May 1975. This regulation ensures that the specified aircraft maintain the required safety standards, thus protecting both the operators and passengers. The scope of the directive is clearly defined, ensuring that the affected entities adhere to the specified safety measures within the designated timeframe.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, include detailed directives aimed at ensuring the airworthiness of certain aircraft models. One such directive, AD/CESSNA 188/25 Amendment 1, pertains to the engine air inlet duct of all model A188 and A188B Cessna Agwagon series aeroplanes with serial numbers (S/Nos.) ranging from 18800833 to 18801824, inclusive of those with a "T" suffix. The directive requires compliance with either Cessna Service Letters (SL) SE75-5 or SE74-23, referencing FAA Airworthiness Directives (AD) 74-23-07 and 75-09-06. This compliance must be achieved within 50 hours of the aeroplane's time in service after 12 May 1975. The obligations imposed by this directive are specific and clear. Owners and operators of the affected Cessna 188 series aeroplanes must ensure that the engine air inlet duct modifications are carried out as specified in the referenced Cessna Service Letters or FAA Airworthiness Directives. This involves inspecting the air inlet duct for any signs of damage or wear and making necessary repairs or replacements to ensure that the duct maintains its structural integrity and functionality. The directive mandates that these actions be completed within the stipulated timeframe to maintain the aircraft's airworthiness certification. Failure to comply with the requirements outlined in AD/CESSNA 188/25 Amendment 1 can have significant legal and operational consequences. Civil penalties may be imposed for non-compliance, including fines and potential grounding of the aircraft until the necessary actions are taken. Furthermore, continued operation of a non-compliant aircraft can result in criminal charges, with severe penalties including substantial fines and imprisonment. These measures are in place to ensure that the safety and operational standards set by the Civil Aviation Safety Authority (CASA) are rigorously upheld.
