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 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.
Boeing 717 Series Aeroplanes
AD/B717/10 Main Spoiler Actuators Support Fitting
Assemblies
10/2003
Applicability: All Model 717-200 series aircraft.
Requirement: Inspect in accordance with the technical requirements of FAA AD 2003-14-05 Amdt 39-13224.
Note: Boeing Alert Service Bulletin 717-57A0016 refers.
Compliance: As specified in the Requirement document, with a revised effective date of 2 October 2003.
This Airworthiness Directive becomes effective on 2 October 2003.
Background: Since the issue of FAA AD 2003-04-24 (AD/B717/7), the FAA has received new reports indicating cracking in one of the four spoiler main actuator support fitting assemblies. At least one cracked support fitting has been reported at each of the four locations. Boeing is still investigating the cause(s) of the cracking. This Directive requires repetitive inspections for cracking of the support fitting assemblies and stop pads of the main spoiler actuators, and follow-up actions.

Overview
The Civil Aviation Safety Regulations 1998, established by the Australian Parliament, are a comprehensive set of rules aimed at ensuring the safety of civil aviation within Australia. One particular aspect of these regulations is detailed in the Airworthiness Directives, which are legislative instruments issued under the authority of the Civil Aviation Safety Authority (CASA). For instance, AD/B717/10, issued in 2003, targets a specific issue with Boeing 717 series aeroplanes, requiring inspections for cracking in the main spoiler actuator support fitting assemblies. This directive was prompted by new reports of cracking, a safety concern that needed to be addressed to prevent potential failures mid-flight. The policy objective of such directives is to ensure that all aircraft operating within Australia meet the necessary safety standards, thereby protecting passengers, crew, and the general public from aviation-related risks.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, mandate the applicability of Airworthiness Directives (AD) issued by the Civil Aviation Safety Authority (CASA) for the maintenance of aircraft safety standards. The AD in question pertains to Boeing 717 series aeroplanes, requiring mandatory inspection of the main spoiler actuator support fitting assemblies to prevent cracking, as outlined in FAA AD 2003-14-05. This AD applies universally to all Model 717-200 series aircraft and mandates adherence to the inspection protocols detailed in the FAA directive, with compliance required by the specified date. This regulatory framework is enforced across the Commonwealth of Australia, ensuring that all aircraft operating within its jurisdiction meet the prescribed safety standards. The AD is effective from the revised date of 2 October 2003, as published in the Commonwealth of Australia Gazette on 10 September 2003, and any failure to comply with the directive may result in legal repercussions under the Civil Aviation Act 1988.
Key Provisions
The Airworthiness Directive (AD/B717/10) issued by the Civil Aviation Safety Authority (CASA) under subregulation 39.1 (1) of the Civil Aviation Safety Regulations 1998, mandates that inspections be conducted on all Model 717-200 series aircraft. This directive, effective from 2 October 2003, applies specifically to the main spoiler actuator support fitting assemblies. The inspections must comply with the technical requirements outlined in the Federal Aviation Administration (FAA) AD 2003-14-05 Amendment 39-13224, with reference to Boeing Alert Service Bulletin 717-57A0016. The AD was necessitated by reports of cracking in the spoiler main actuator support fitting assemblies, which have been identified at all four locations on the aircraft.
Operators and owners of Boeing 717-200 series aircraft are required to conduct these inspections as specified in the directive. This entails following the detailed instructions provided in the FAA AD and Boeing's service bulletin, which include the procedures for identifying and addressing any cracking in the support fitting assemblies and stop pads of the main spoiler actuators. Compliance with these inspection requirements must be achieved by the specified date, 2 October 2003. Failure to adhere to these inspection mandates could result in the aircraft being deemed unairworthy, leading to potential operational restrictions or grounding of the aircraft until the necessary inspections and repairs are completed.
The AD carries significant consequences for non-compliance. Operators who fail to comply with the inspection requirements outlined in the AD may face enforcement actions by CASA. Potential penalties can include fines, operational restrictions, or even the revocation of the aircraft’s certificate of airworthiness. These measures are intended to ensure that the safety risks associated with the identified cracking are mitigated. The maximum penalties for non-compliance are not explicitly stated in the AD but are governed by the broader regulatory framework under which CASA operates, which could include substantial financial penalties and legal ramifications.
In summary, the AD/B717/10 is a critical safety measure aimed at addressing the identified risk of cracking in the main spoiler actuator support fitting assemblies of Boeing 717-200 series aircraft. Operators must meticulously follow the specified inspection protocols to ensure compliance and maintain the airworthiness of their aircraft, avoiding the severe consequences associated with non-compliance.
