AD/CESSNA 210/52 Amdt 2 - Engine Exhaust System - Inspection

Overview

The Civil Aviation Regulations 1998 (Cth) were enacted by the Parliament of Australia to regulate and ensure safety within the civil aviation sector. One specific aspect of these regulations is addressed in Part 39, which includes various airworthiness directives. The purpose of these directives is to ensure that aircraft meet the required safety standards, and one such directive pertains to the Cessna 210 Series aeroplanes. The Civil Aviation Safety Authority (CASA) issues these directives to mandate inspections and repairs that ensure aircraft remain airworthy and safe for operation. AD/CESSNA 210/52 Amendment 2, for example, pertains to the engine exhaust system and was introduced to mitigate risks associated with carbon monoxide entering the cabin and to prevent the loss of engine and electrical power. The policy objective here is to maintain and enhance the safety of aviation operations by enforcing regular inspections and timely repairs.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to airworthiness directives concerning aircraft, including the Cessna 210 Series Aeroplanes. This particular legislation, AD/CESSNA 210/52 Amendment 2, applies to the P210N model of Cessna aircraft with serial numbers ranging from P21000001 to P21000811 that are not equipped with the specified complete inconel exhaust systems. The directive mandates inspections of the engine exhaust system to mitigate the risk of carbon monoxide infiltration into the cabin and to prevent potential loss of engine and electrical power. Compliance with these directives is mandatory for the specified aircraft, with initial inspections required within 25 hours of operation post-31 December 1982, followed by inspections at intervals not exceeding 50 hours of service, except as detailed in the repair procedures outlined in Cessna SIL SE82-3. This legislation extends its reach to all applicable aircraft within the Commonwealth of Australia and may be subject to further specifications or modifications through subordinate instruments.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, mandate specific airworthiness directives for the Cessna 210 series aeroplanes, as detailed in AD/CESSNA 210/52 Amendment 2. This directive applies to Model P210N aircraft with serial numbers ranging from P21000001 to P21000811 that are not equipped with complete inconel exhaust systems. Specifically, these systems should consist of Cessna part numbers 2154000-53 for the left-hand assembly, 2154000-54 for the right-hand assembly, and 2154000-68 for the forward crossover assembly. This directive references Cessna SIL No. SE82-3 and its supplement to provide detailed repair and inspection procedures. This legislation imposes a critical obligation on the owners or operators of the specified Cessna 210 series aeroplanes to ensure compliance with the outlined inspection requirements. The initial inspection must be conducted within 25 hours of time in service after 31 December 1982, unless it has already been performed under previous directives. Subsequent inspections must occur at intervals not exceeding 50 hours of time in service, unless otherwise specified in the repair procedures outlined in Cessna SIL SE82-3. The purpose of these inspections is to mitigate the risk of carbon monoxide entering the cabin and to prevent potential loss of engine and electrical power. Failure to comply with the requirements set out in this airworthiness directive may result in serious safety implications, potentially leading to civil or criminal consequences. Although the specific penalties are not detailed in the text, it is implied that non-compliance with aviation safety directives can result in substantial fines, penalties, or even grounding of the aircraft. The exact penalties would be determined by the Civil Aviation Safety Authority (CASA) in accordance with the broader Civil Aviation Regulations 1998 and any other applicable legislation. Additionally, the directive notes that FAA AD 81-23-03 R2 also pertains to the issue, indicating that international regulatory standards are considered in this framework. The directive has been amended to exclude aircraft that are already fitted with the specified complete inconel exhaust systems, ensuring that only those aeroplanes at risk are subject to these inspections. This careful delineation aims to maintain the safety and airworthiness of the affected aircraft within the Australian aviation sector.
