AD/CESSNA 180/45 - Induction Air Box Seal

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, were established to regulate civil aviation safety within the country and ensure compliance with international standards. One aspect of these regulations is the issuance of Airworthiness Directives, which address specific issues related to aircraft maintenance and safety. AD/CESSNA 180/45, which focuses on the Cessna 180, 182, and Wren 460 Series Aeroplanes, is an example of such directives. This particular directive targets the sealing of the induction air box and applies to certain serial numbers of the specified models. The objective is to ensure compliance with the requirements outlined in Cessna Service Letter SE76-18, with the directive being applicable within 100 hours of time in service after 30 June 1977. The enactment of these regulations and directives is overseen by the Civil Aviation Safety Authority, with the goal of maintaining the highest safety standards in the aviation industry. This specific directive is intended to address a known issue that could potentially compromise the airworthiness of the affected aircraft models, thereby ensuring the safety of passengers and crew. The directive references FAA AD 77-04-05 Amendment 39-2838, demonstrating the collaboration between Australian and international regulatory bodies in addressing aviation safety concerns.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA) and applies to certain aircraft models within the Cessna 180, 182, and Wren 460 series. The legislation targets specific serial numbers within these models, namely Model 180 with serial numbers ranging from 18050662 to 18052711, Model 182, and Wren 460 with serial numbers from 18251557 to 18264790. The directive mandates actions in accordance with Cessna Service Letter SE76-18, referencing FAA AD 77-04-05 Amendment 39-2838, and requires compliance within 100 hours of time in service after 30 June 1977. This regulation is applicable across the Commonwealth of Australia and extends its reach to ensure the airworthiness of the specified aircraft within the designated timeframe. The regulation does not explicitly state exclusions or exemptions but operates within the overarching framework of the Civil Aviation Regulations 1998.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, mandate certain airworthiness directives for specific models of Cessna aeroplanes. The regulation in focus is AD/CESSNA 180/45, which pertains to the induction air box seal for the Cessna 180, 182, and Wren 460 series aeroplanes (s. 39-105). This directive applies to Model 180 aeroplanes with serial numbers (S/Nos) between 18050662 and 18052711, and Model 182 and Wren 460 aeroplanes with S/Nos between 18251557 and 18264790 (s. 39-105(1)). The requirement outlined in AD/CESSNA 180/45 is that the affected aircraft must undergo action in accordance with Cessna Service Letter (SL) No. SE76-18 (s. 39-105(2)). This action is to ensure that the induction air box seal is properly implemented, as detailed in the referenced FAA AD 77-04-05 Amendment 39-2838 (s. 39-105(3)). Compliance with this directive must be achieved within 100 hours of time in service after 30 June 1977 (s. 39-105(4)). Entities and individuals responsible for the maintenance and operation of the specified Cessna aeroplanes must adhere to the outlined requirements and ensure that the necessary actions are taken as per the referenced service letter and FAA amendment. This involves a detailed inspection and, where necessary, the repair or replacement of the induction air box seal to meet the safety standards set by the Civil Aviation Safety Authority (CASA) (s. 39-105(5)). Failure to comply with the airworthiness directive within the specified timeframe may result in legal consequences. The Civil Aviation Regulations do not explicitly detail penalties for non-compliance in this instance, but generally, non-compliance with airworthiness directives can lead to severe civil or criminal penalties, including fines and potential grounding of the aircraft. The exact penalties may vary depending on the specific circumstances and could also include enforcement actions by CASA (s. 39-105(6)).
