COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below revokes Airworthiness Directive (AD) AD/CESSNA 207/36 and issues the following AD under subregulation 39.1 (1) of CASR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Cessna 207 Series Aeroplanes
AD/CESSNA 207/36
Amdt 1
Brackett Engine Air Filters 5/2003
Applicability: Cessna T207 series aircraft incorporating a Brackett Aero Filters Inc. engine air inlet filter Part Number (P/N) BA-2410.
Note 1: Brackett air filters are an approved alternative to the original Cessna air filter. This Directive is only applicable to aircraft that have had the original Cessna air filter replaced by a Brackett air filter.
Requirement: Inspect the engine air filter element for correct installation. If the filter has only one grill screen, install an additional grill screen P/N 2404-00.
Note 2: The BA-2410 filter element was revised in 1993 to have a screen on both faces of the filter.
Note 3: FAA AD 2002-26-03 refers.
Compliance: Effective 15 May 2003; unless previously accomplished; at next access to the engine air filter or next scheduled aircraft periodic inspection, whichever occurs first.
This amendment becomes effective on 15 May 2003.
Background: This Directive was originally issued to require an inspection of Brackett engine air inlet filters to ensure the filter has been installed correctly. The requirement reflects the NTSB investigation of a fatal Cessna T210 accident disclosed the single grill screen had been installed incorrectly allowing the filter element to be ingested. This amendment requires a second screen to be installed on all applicable Brackett air filter installations.
The original issue of this Airworthiness Directive became effective on 11 July 2002.

Overview
The Civil Aviation Safety Regulations 1998 (CASR) represent a key legislative instrument enacted by the Parliament of the Commonwealth of Australia to ensure the safety of civil aviation. Among its provisions, Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, provides a mechanism for the Civil Aviation Safety Authority (CASA) to issue Airworthiness Directives (AD) to address safety concerns. These directives are designed to rectify any unsafe conditions identified in aircraft or aeronautical products. The policy objective of these regulations is to maintain the highest standards of aviation safety, thereby protecting the public and contributing to the efficient and orderly development of civil aviation. The specific Airworthiness Directive AD/CESSNA 207/36 Amendment 1, issued on 3 April 2003 and effective from 15 May 2003, was introduced to address the identified risk associated with the incorrect installation of Brackett engine air filters on Cessna 207 series aircraft, following an investigation into a fatal accident that highlighted the potential for the filter element to be ingested by the engine if improperly installed.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39-105, govern airworthiness directives in the Commonwealth of Australia, with the Civil Aviation Safety Authority (CASA) as the regulatory body. The scope of this particular Airworthiness Directive (AD) pertains to the Cessna 207 series aeroplanes that have had their original Cessna air filters replaced with Brackett Aero Filters Inc. engine air inlet filters, specifically Part Number (P/N) BA-2410. This directive is crucial for ensuring the correct installation of engine air filters to prevent unsafe conditions that could lead to accidents. The AD mandates an inspection of the engine air filter element and the installation of an additional grill screen P/N 2404-00 if the filter only has one grill screen, reflecting findings from an investigation into a fatal accident involving a Cessna T210. Compliance with this AD is mandatory and must be carried out by 15 May 2003, or at the next access to the engine air filter or next scheduled aircraft periodic inspection, whichever occurs first. This directive extends across the Commonwealth of Australia and is applicable to all operators of the specified Cessna aircraft that have installed the Brackett air filters.
Key Provisions
The main operative sections of this Civil Aviation Safety Regulation (CASR) are sections 39.1(1), which allows the delegate of the Civil Aviation Safety Authority (CASA) to issue an Airworthiness Directive (AD) to correct unsafe conditions in aircraft or aeronautical products. The AD requires specific actions to be taken on particular aircraft types in specific circumstances, as detailed in the requirement section. The AD in question is AD/CESSNA 207/36, which applies to Cessna T207 series aircraft that have had the original Cessna air filter replaced by a Brackett air filter.
This AD imposes obligations on the parties governed by it, including operators and owners of the specified Cessna aircraft models. Specifically, these parties must ensure that the engine air filter element is inspected for correct installation. If the filter only has one grill screen, they must install an additional grill screen P/N 2404-00 to meet the AD requirements. Compliance with the AD is mandatory and must be achieved by the next access to the engine air filter or the next scheduled aircraft periodic inspection, whichever comes first.
The AD also includes potential consequences for non-compliance. While the AD itself does not explicitly outline penalties, the overarching CASR 1998 may include provisions for civil or criminal penalties for failing to comply with an AD. Non-compliance could lead to enforcement actions under the Civil Aviation Act 1988, which may include fines, imprisonment, or other legal consequences. The exact penalties would depend on the specific breach and the relevant provisions of the Civil Aviation Act 1988.
