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 210/71 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 210 Series Aeroplanes
AD/CESSNA 210/71
Amdt 1
Brackett Engine Air Filters 5/2003
Applicability: Cessna 210 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, administered by the Civil Aviation Safety Authority (CASA), address the need to ensure the safety of civil aviation in Australia. Enacted by the Parliament of Australia, these regulations provide a comprehensive framework for maintaining airworthiness standards, safety oversight, and the implementation of airworthiness directives to address safety issues as they arise. The problem this legislation seeks to mitigate includes ensuring that all aircraft meet stringent safety standards and that any identified unsafe conditions are promptly addressed through regulatory mandates. The policy objective is to protect public safety and enhance the overall safety of civil aviation in Australia by ensuring that aircraft and aeronautical products comply with airworthiness standards. This is achieved through the issuance of airworthiness directives that mandate specific actions to rectify identified safety concerns, as exemplified by the recent amendment to Airworthiness Directive AD/CESSNA 210/71 concerning Brackett engine air filters in Cessna 210 series aircraft.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directives (AD) that apply to the aviation industry, focusing on the safety of aircraft operations. This particular AD pertains to the Cessna 210 series aeroplanes equipped with a Brackett Aero Filters Inc. engine air inlet filter part number BA-2410, which must be inspected for correct installation and may require the installation of an additional grill screen part number 2404-00 if it has only one grill screen. The directive applies to all Cessna 210 series aircraft that have had the original Cessna air filter replaced by a Brackett air filter, and the compliance is required to be met by 15 May 2003, either at the next access to the engine air filter or next scheduled aircraft periodic inspection, whichever comes first. This directive is a response to safety concerns identified by the National Transportation Safety Board (NTSB) following a fatal accident, and it mandates that operators take necessary corrective actions to prevent similar incidents. The AD is a legislative instrument issued under the authority of the Civil Aviation Safety Authority (CASA) and is applicable throughout the Commonwealth of Australia.
Key Provisions
The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 105, includes a provision for issuing Airworthiness Directives (AD) to ensure the safety of aircraft. The Airworthiness Directive AD/CESSNA 210/71, Amendment 1, issued on 5 May 2003, pertains to the Brackett Engine Air Filters for Cessna 210 series aircraft. This AD applies to any Cessna 210 series aircraft that have installed Brackett Aero Filters Inc. engine air inlet filters, specifically P/N BA-2410 (section 5). The directive requires an inspection of the engine air filter element to ensure correct installation. If the aircraft has only one grill screen, an additional grill screen P/N 2404-00 must be installed (section 5). The AD references FAA AD 2002-26-03 and notes that the BA-2410 filter element was revised in 1993 to include screens on both faces of the filter (section 5, Note 2 and 3).
The AD imposes an obligation on the owners and operators of Cessna 210 series aircraft to inspect the Brackett engine air filters as specified in the directive. The compliance section mandates that the inspection and necessary installation of an additional screen must be completed by the next access to the engine air filter or next scheduled aircraft periodic inspection, whichever occurs first (section 5, Compliance). The directive became effective on 15 May 2003, unless the inspection and installation have already been carried out (section 5, Compliance). This requirement ensures that the air filters are correctly installed to prevent any unsafe conditions that could potentially lead to accidents, such as the ingestion of the filter element.
Failure to comply with the AD AD/CESSNA 210/71, Amendment 1, may result in legal consequences. While the specific penalties are not outlined in the text, non-compliance with Airworthiness Directives generally may lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions could include fines, grounding of the aircraft, or other regulatory measures to ensure compliance with aviation safety standards. The seriousness of the potential consequences underscores the importance of adhering to the directive to maintain the airworthiness of the aircraft and ensure the safety of all persons onboard.
