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.
British Aerospace BAe 125 Series Aeroplanes
AD/HS 125/172 Rosemount Pitot Probes 8/2004
Applicability: Model Hawker 800XP aeroplanes having serial number 258266 and serial numbers 258277 through 258500 inclusive.
Requirement: 1. Replace the existing Rosemount Aerospace 853JF pitot probes with new Rosemount Aerospace 853JF1 pitot probes (includes installing a new ammeter, two new shunts, and improved electrical writing), in accordance with paragraph
3.A. of the Accomplishment Instructions of Raytheon Service Bulletin SB 34- 3412, dated March 2001.
2. Rosemount Aerospace 853JF pitot probe or an ammeter having P/N 2132-01- 0017, shall not be installed on any aeroplane as a replacement part.
Note: FAA AD 2004-09-26 Amdt 39-13616 refers.
Compliance: For Requirement 1 - At the next scheduled 24-month inspection, but no later than 6 months after the effective date of this Directive.
For Requirement 2 - As of the effective date of this Directive.
This Airworthiness Directive becomes effective on 5 August 2004.
Background: This Directive requires replacement of certain existing pitot probes with new probes.
This action is necessary to prevent loss or fluctuation of indicated airspeed, which could result in hazardously misleading information being provided to the flight crew.

Delegate of the Civil Aviation Safety Authority 23 June 2004
The above AD is notified in the Commonwealth of Australia Gazette on 14 July 2004.
Overview
The Civil Aviation Safety Regulations 1998 (CASR) were enacted to regulate the safety of civil aviation within Australia, ensuring that all aircraft and aeronautical products meet specific safety standards. The Civil Aviation Safety Authority (CASA) is responsible for enforcing these regulations, and one of its functions is to issue Airworthiness Directives (ADs) to address specific safety concerns. For example, AD/HS 125/172, issued on 5 August 2004, targets Hawker 800XP aeroplanes with certain serial numbers, mandating the replacement of specific Rosemount pitot probes to prevent hazardously misleading airspeed information. This directive was necessary to rectify an unsafe condition identified in the aircraft, and it became effective immediately upon its issuance, with compliance required within specified timeframes. The AD was published in the Commonwealth of Australia Gazette on 14 July 2004 to ensure wide dissemination and compliance by the relevant stakeholders.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, pertains to airworthiness directives issued by the Civil Aviation Safety Authority (CASA) under the authority of the Civil Aviation Act 1988. This particular Airworthiness Directive (AD) targets the Hawker 800XP aeroplanes with serial numbers ranging from 258266 and 258277 through 258500 inclusive. The directive mandates the replacement of certain Rosemount Aerospace 853JF pitot probes with new Rosemount Aerospace 853JF1 probes, inclusive of installing a new ammeter, two new shunts, and improved electrical wiring, in accordance with specified instructions. Additionally, it prohibits the installation of Rosemount Aerospace 853JF pitot probes or an ammeter with a specific part number on any aeroplane as a replacement part. The directive applies nationally within Australia, and its implementation is overseen by CASA. Compliance with the directive must occur at the next scheduled 24-month inspection, no later than six months after its effective date of 5 August 2004. The directive is effective immediately upon its publication in the Commonwealth of Australia Gazette on 14 July 2004.
Key Provisions
The Civil Aviation Safety Regulations 1998, specifically within PART 39 - 105, outlines a requirement for certain aircraft to comply with an Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA). AD/HS 125/172 pertains to the replacement of Rosemount pitot probes on British Aerospace BAe 125 Series aeroplanes, specifically those with serial numbers 258266 and those ranging from 258277 to 258500 inclusive (section 1). The directive mandates that the existing Rosemount Aerospace 853JF pitot probes must be replaced with new Rosemount Aerospace 853JF1 pitot probes, including the installation of a new ammeter, two new shunts, and improved electrical wiring, as per the instructions in Raytheon Service Bulletin SB 34-3412, paragraph 3.A (section 2). Additionally, it prohibits the installation of the Rosemount Aerospace 853JF pitot probe or an ammeter with part number 2132-01-0017 as a replacement part (section 3).
The AD imposes specific obligations on the owners and operators of the affected aircraft. They must ensure that the replacement of the pitot probes is carried out as per the requirements set out in the directive. For Requirement 1, the replacement must occur at the next scheduled 24-month inspection but no later than six months after the effective date of the directive (section 4). For Requirement 2, the prohibition on installing the specified pitot probes or ammeter must be adhered to immediately upon the effective date of the directive (section 5). Compliance with these requirements ensures the continued airworthiness of the aircraft and the safety of all personnel on board.
Failure to comply with the AD may result in significant consequences. The AD does not explicitly outline specific penalties, but non-compliance with CASA directives can lead to severe civil and criminal penalties. Civil penalties can include fines up to the maximum statutory limits, and criminal penalties can include imprisonment for individuals responsible for ensuring compliance. The severity of the penalties may depend on the degree of negligence or intent behind the non-compliance, as well as any resultant accidents or safety breaches. Ensuring adherence to the AD is, therefore, crucial for the safety and legality of operating the affected aircraft.
