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 CAR 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.
AD/BAe 146/87 Pitot Static System 5/2001
Applicability: All Avro 146-RJ70, RJ85 and RJ100 series aeroplanes with modification HCM01080W embodied.
Requirement: 1. Operators who have not inspected their aircraft as a result of BAe Systems All Operator Message (AOM) 00/029V – Action in accordance with BAe Systems Inspection Service Bulletin ISB.34-338 dated 14 February 2001.
2. Operators who have inspected their aircraft as a result of AOM 00/029V and can confirm that chafing was not present but cannot demonstrate full compliance with of ISB.34-338 – Complete the outstanding ISB.34-338 actions in accordance with the ISB.
3. Operators who have inspected their aircraft as a result of AOM 00/029V and can demonstrate full compliance with the contents of ISB.34-338 – No further action is necessary.
Note: These actions have been classified as Mandatory by the CAA(UK).
Compliance: For Requirement 1 – Within three months after the effective date of this Directive.
For Requirement 2 – Within two years after the effective date of this Directive. This Airworthiness Directive becomes effective on 17 May 2001.
Background: Operators have reported chafing of the S4 and S5 static pipes against the avionics rack frame 18 starboard outboard pipe clamp position. Loss of integrity of both the S4 and S5 static pipes could result in loss of maximum differential pressure protection for the aircraft.
COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
This Directive requires inspection of pipes for chafing and to ensure adequate clearance. If necessary, the Directive also provides for repositioning of pipes and/or repair of any chafed areas.

Delegate of the Civil Aviation Safety Authority 6 April 2001
The above AD is notified in the Commonwealth of Australia Gazette on 18 April 2001.
Overview
The Civil Aviation Regulations 1998, as amended, include a schedule of Airworthiness Directives aimed at maintaining the safety and airworthiness of aircraft. Enacted by the Parliament of the Commonwealth of Australia, this legislation plays a crucial role in ensuring that civil aviation operations within Australia adhere to stringent safety standards. Specifically, the Airworthiness Directive issued under this regulation addresses the problem of chafing in the S4 and S5 static pipes of Avro 146-RJ70, RJ85, and RJ100 series aeroplanes, which could compromise the structural integrity necessary for safe flight operations. The policy objective of this directive is to mandate specific inspections and corrective actions to mitigate potential safety hazards, thereby enhancing overall aviation safety.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate Airworthiness Directives (ADs) to ensure the safety and airworthiness of aircraft operating within Australia. The AD/BAe 146/87 issued on 5 May 2001 pertains to all Avro 146-RJ70, RJ85, and RJ100 series aeroplanes that have incorporated modification HCM01080W. The directive applies to operators of these aircraft, requiring them to inspect and address any chafing of the S4 and S5 static pipes against the avionics rack frame at the specified 18 starboard outboard pipe clamp position. Failure to comply with these inspections and necessary actions could result in loss of maximum differential pressure protection, posing a significant safety risk. The AD outlines specific compliance timelines and actions, including mandatory inspections within three months for those who have not yet inspected their aircraft, and within two years for those who have identified but not fully resolved the chafing issue. This AD is enforced under the authority of the Civil Aviation Safety Authority, with the directive becoming effective from 17 May 2001.
Key Provisions
The Civil Aviation Regulations 1998, particularly in Part 39 - 105, outlines an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) concerning the British Aerospace BAe 146 Series Aeroplanes. Specifically, AD/BAe 146/87 mandates actions to address an issue related to the Pitot Static System (section 1). This AD applies to all Avro 146-RJ70, RJ85, and RJ100 series aeroplanes that have the modification HCM01080W incorporated (section 2). The requirement section outlines three distinct actions based on the current status of the aircraft inspection and compliance with previous directives. For operators who have not yet inspected their aircraft in response to BAe Systems All Operator Message (AOM) 00/029V, they must inspect and act in accordance with BAe Systems Inspection Service Bulletin ISB.34-338 dated 14 February 2001 (section 3(1)). For operators who have inspected their aircraft as per AOM 00/029V but have not fully complied with ISB.34-338, they are required to complete the outstanding actions specified in ISB.34-338 (section 3(2)). Operators who have inspected their aircraft and can demonstrate full compliance with ISB.34-338 are not required to take any further action (section 3(3)).
The AD imposes several obligations on the operators of the specified aircraft. Firstly, operators must ensure that the inspections and any necessary actions are carried out within the stipulated timeframes. For operators who have not yet inspected their aircraft, the inspection and subsequent actions must be completed within three months of the AD's effective date (section 4(1)). Operators who have inspected their aircraft but have not fully complied with ISB.34-338 must complete the remaining actions within two years of the AD's effective date (section 4(2)). Compliance with these obligations is critical to maintaining the airworthiness of the aircraft and ensuring the safety of all persons on board.
Failure to comply with the provisions of this Airworthiness Directive can result in severe consequences. While the specific penalties are not detailed in the text, non-compliance with CASA directives generally can lead to significant civil or criminal penalties. These can include fines, suspension or revocation of operating certificates, and potential criminal charges for individuals responsible for the non-compliance. The seriousness of these consequences underscores the importance of adhering to the AD's requirements to ensure the safety and airworthiness of the aircraft.
