SCHEDULE OF AIRWORTHINESS DIRECTIVES
Thereafter, repetitively inspect BFGoodrich P/N 2-1203, 2-1203-1, or 2-1203-3 brakes:
- If the clearance is .200 inches or more, but is less than .250 inches: inspect at intervals not to exceed 75 hours time in service until clearance is .250 inches or more, at which time replacement is required.
b. If the clearance is less than .200 inches, inspect at intervals not to exceed 250 hours time in service, until the clearance is .200 inches or more.
Note: These wear and clearance limits differ from, and take precedence over, the limits contained in the service information.
2. Before 6 June 1992.
The compliance times remain unchanged for the Requirement 1 P/N 2-1203-3 brake initial inspection, and the Requirement 2 modification.
This Airworthiness Directive becomes effective on 28 December 2000.
Background: Wheel brake system malfunctions have occurred on several of the affected aircraft where regular brake system maintenance had been performed. The actions specified by this Directive are intended to prevent wheel brake system malfunctions that could result in a fire in the brake area.
Amendment 1 is issued in response to a new FAA AD which incorporates inspection and replacement requirements for additional landing gear brake assemblies. The FAA AD specifies wear and maximum clearance limits which take precedence over those specified in the service information.
The original issue of this Airworthiness Directive became effective on 6 March 1992.

Delegate of the Civil Aviation Safety Authority 8 November 2000
The above AD is notified in the Commonwealth of Australia Gazette on 22 November 2000.
Overview
The Civil Aviation Regulations 1998 (CAR 1998) were enacted to regulate civil aviation operations and ensure the safety of aircraft and personnel in Australia. The Civil Aviation Safety Authority (CASA), as a delegate of the Commonwealth of Australia, issues Airworthiness Directives under subregulation 39.1 (1) of CAR 1998 to address specific safety concerns. The problem or gap addressed by this particular Airworthiness Directive (AD/SWSA226/65 Amendment 1) concerns the prevention of wheel brake system malfunctions on Fairchild (Swearingen) SA226 and SA227 series aeroplanes, which could potentially lead to fires in the brake area. The policy objective is to mandate specific inspection and modification procedures to ensure the safe operation of these aircraft. This amendment responds to a new Federal Aviation Administration (FAA) AD that includes additional inspection and replacement requirements for landing gear brake assemblies, taking precedence over existing service information limits.
Scope and Application
The Airworthiness Directive (AD) AD/SWSA226/65, issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998, applies specifically to Fairchild (Swearingen) SA226 and SA227 series aeroplanes. The directive mandates inspections and modifications to the brake systems of certain models of these aircraft, with serial numbers falling within the specified ranges for each model. The requirement to inspect and measure brake wear and clearance limits must be performed according to procedures outlined in BFGoodrich Service Letter No. 1498. Additionally, the parking brake system must be modified as per Fairchild Service Bulletin (SB) 227-32-017 or SB 226-32-049, depending on the model. Compliance deadlines are set based on the brake part numbers and the time in service, with repetitive inspections required at specified intervals if the clearance limits are exceeded. This AD is effective from 28 December 2000 and supersedes previous directives to ensure that the safety concerns identified, particularly the risk of wheel brake system malfunctions leading to fires, are addressed effectively.
Key Provisions
The Civil Aviation Regulations 1998, Part 39 - 105, establishes the schedule of airworthiness directives (ADs) for specific aircraft, such as the Fairchild (Swearingen) SA226 and SA227 series aeroplanes. In particular, the AD in question addresses issues with the brake systems of these aircraft models, aiming to prevent malfunctions that could lead to fires. The AD, identified as AD/SWSA226/65 Amendment 1, was issued by a delegate of the Civil Aviation Safety Authority (CASA) under subregulation 39.1(1) of the Civil Aviation Regulations 1998. The directive applies to certain serial numbers of the SA226 and SA227 models, as detailed in the applicability section of the AD (sections 1-2).
The AD mandates two key actions to address the identified safety concerns. Firstly, it requires an inspection and measurement of the brake wear and clearance limits according to procedures specified in BFGoodrich Service Letter No. 1498 (section 1). Secondly, it mandates a modification of the parking brake system in accordance with Fairchild Service Bulletins 227-32-017 or 226-32-049, as applicable (section 2). These requirements must be fulfilled under specific conditions, as outlined in the compliance section of the AD, which includes time limits based on the aircraft's service hours and the installation date of certain brake parts.
The AD imposes specific obligations on the parties governed by it. Owners and operators of the affected aircraft must ensure that the required inspections and modifications are performed by qualified personnel within the stipulated time frames. The AD also references FAA AD 2000-17-01 Amendment 39-11874, indicating that the Australian directive is in alignment with international safety standards. Compliance with the AD is critical to maintaining the airworthiness of the affected aircraft and ensuring the safety of passengers and crew.
Failure to comply with the AD may result in significant consequences. The AD does not explicitly state penalties or consequences for non-compliance, but under the Civil Aviation Regulations 1998, non-compliance with airworthiness directives can lead to serious ramifications. This may include the grounding of the aircraft, enforcement actions by CASA, and potential civil or criminal penalties. The specific penalties would depend on the nature and severity of the non-compliance, but they could include fines and imprisonment for individuals found guilty of breaches that result in harm or endanger safety.
