SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (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.
Rotax Piston Engines
AD/ROTAX/13 Mixture Enrichment Jet 12/2003
Applicability: Rotax 914 F series engines. Serial Numbers 4.420.002 up to 4.420.029 and 4.420.032 up to 4.420.044.
Requirement: Verify the calibration of the mixture enrichment jet in accordance with Bombardier Technical Bulletin Number 914-03.
Note: Austrian Airworthiness Directive Number 88 refers.
Compliance: No later than 30 November 2003.
This Airworthiness Directive becomes effective on 27 November 2003.
Background: This directive has been issued in response to advice from the engine manufacturer that applicable engines may have had the pressure control bore of the mixture enrichment jet incorrectly installed.

Overview
The Civil Aviation Safety Regulations 1998, under the Civil Aviation Act 1988, were enacted to address the need for stringent safety standards in the aviation industry, aiming to ensure that all aircraft and aeronautical products meet the necessary safety requirements to protect the public and aviation personnel. The Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (ADs) to mandate specific safety actions when an unsafe condition is identified. For example, AD/ROTAX/13, issued on 12 December 2003, targets certain Rotax 914 F series engines with specific serial numbers, requiring the calibration of the mixture enrichment jet to be verified in accordance with Bombardier Technical Bulletin Number 914-03. This directive was introduced in response to the manufacturer’s advice that the pressure control bore of the mixture enrichment jet might have been incorrectly installed, thereby necessitating corrective action to ensure airworthiness. The policy objective is to mitigate safety risks associated with such discrepancies, ensuring continued compliance with safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically under Part 39 - 106, outline Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft and aeronautical products. The particular Airworthiness Directive AD/ROTAX/13 pertains to the calibration of the mixture enrichment jet for the Rotax 914 F series engines, addressing a potential safety issue related to the incorrect installation of the pressure control bore in the mixture enrichment jet. The directive applies to engines with serial numbers ranging from 4.420.002 to 4.420.029 and 4.420.032 to 4.420.044. Compliance with this directive is mandatory, requiring the calibration verification to be conducted in accordance with Bombardier Technical Bulletin Number 914-03, with the directive becoming effective on 27 November 2003 and requiring completion by 30 November 2003. This directive, issued under the authority of the CASA delegate, is applicable nationally and aims to rectify the identified unsafe condition in the specified engines to maintain compliance with civil aviation safety standards.
Key Provisions
The Airworthiness Directive (AD) in question (AD/ROTAX/13), issued under subregulation 39.1(1) of the Civil Aviation Safety Regulations 1998, pertains specifically to the Rotax 914 F series engines, with serial numbers ranging from 4.420.002 to 4.420.029 and from 4.420.032 to 4.420.044. The directive mandates that the calibration of the mixture enrichment jet must be verified in accordance with Bombardier Technical Bulletin Number 914-03. This requirement is to address an issue where the pressure control bore of the mixture enrichment jet may have been incorrectly installed, as indicated by the engine manufacturer. The directive stipulates that this verification must be completed by 30 November 2003.
The AD imposes clear obligations on the holders or operators of the specified Rotax 914 F series engines. They must ensure that the mixture enrichment jet calibration is verified as per the Bombardier Technical Bulletin Number 914-03. This involves conducting a thorough inspection and potentially making necessary adjustments to correct any discrepancies in the jet's pressure control bore installation. The verification must be completed by the specified compliance date to ensure that the engines meet the required airworthiness standards.
Failure to comply with the requirements outlined in the AD may result in significant consequences. Although the specific penalties or consequences for non-compliance are not detailed in the AD itself, the overarching Civil Aviation Safety Regulations 1998 provide a framework for potential civil or criminal penalties. Non-compliance with an Airworthiness Directive can lead to enforcement actions by the Civil Aviation Safety Authority, including fines, legal proceedings, and potential grounding of the affected aircraft. The seriousness of the potential consequences underscores the importance of adhering to the directive to ensure continued compliance with aviation safety standards.
