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.
Beechcraft 400 Series Aeroplanes
AD/BEECH 400/24 Low Pressure Oxygen Tubing 8/2003
Applicability: Model Beech 400A series aeroplanes, serial numbers RK-232 through RK-265 inclusive; and Model Beech 400T series aeroplane serial number TX-10.
Requirement: For Model 400A series aeroplanes - Replace the low-pressure oxygen tubing located in the forward fuselage (nose avionics bay), lower forward flight deck, and lower forward cabin areas, as applicable, with new low-pressure oxygen tubing, in accordance with Part I of the Accomplishment Instructions specified in Raytheon Service Bulletin SB 35-3406, dated March 2001.
For Model 400T series aeroplanes - Replace the low-pressure oxygen tubing located in the forward fuselage (nose avionics bay), lower forward flight deck, and lower forward cabin areas, as applicable, with new low-pressure oxygen tubing, in accordance with Part II of the Accomplishment Instructions specified in SB 35-3406.
Note: FAA AD 2003-10-13 Amdt 39-13158 refers.
Compliance: Within 200 hours time in service or one year, whichever occurs first, from the effective date of this Directive.
This Airworthiness Directive becomes effective on 7 August 2003.
Background: This Directive requires replacement of the low-pressure oxygen tubing located in the forward fuselage (nose avionics bay), lower forward flight deck and lower forward cabin areas, as applicable, with new low-pressure oxygen tubing. This action is necessary to prevent leakage of oxygen from scored low-pressure oxygen tubing, which could result in lack of available oxygen for the flight crew, or possible explosion or fire.

Overview
The Civil Aviation Safety Regulations 1998 (CASR 1998) were enacted to ensure the safety of civil aviation in Australia, addressing the need for a comprehensive regulatory framework governing airworthiness and operational safety. The specific Airworthiness Directive (AD) AD/BEECH 400/24, issued in 2003 by the Civil Aviation Safety Authority (CASA), targets the replacement of low-pressure oxygen tubing in certain Beechcraft 400 series aeroplanes. This directive was introduced to mitigate the risk of oxygen leaks, which could endanger the flight crew and potentially cause explosions or fires. The objective of this AD is to ensure that the specified aircraft models comply with safety standards by replacing the faulty oxygen tubing within a stipulated timeframe, thereby maintaining airworthiness and safeguarding the safety of those on board.
Scope and Application
The Civil Aviation Safety Regulations 1998, under subregulation 39.1 (1), mandates specific airworthiness directives to ensure the safety of aviation operations. One such directive, AD/BEECH 400/24 issued in August 2003, applies to the Beechcraft 400 Series aeroplanes, specifically to Model 400A series aeroplanes with serial numbers RK-232 through RK-265 inclusive, and the Model 400T series aeroplane with serial number TX-10. The directive requires the replacement of low-pressure oxygen tubing in designated areas to mitigate risks of oxygen leakage, which could compromise safety. This directive applies to all aircraft within the specified serial numbers and must be complied with within 200 hours of time in service or one year from the directive's effective date of 7 August 2003. The directive references FAA AD 2003-10-13 Amdt 39-13158 for further guidance and was published in the Commonwealth of Australia Gazette on 16 July 2003.
Key Provisions
The key operative sections of this Airworthiness Directive (AD) include the applicability, requirement, and compliance sections, each of which is explicitly stated in the document (sections 105, 106, and 107 respectively). The applicability section identifies the specific aircraft models affected by the directive: Model Beech 400A series aeroplanes with serial numbers RK-232 through RK-265 inclusive, and Model Beech 400T series aeroplane with serial number TX-10. The requirement section outlines the specific action that must be taken: replacing the low-pressure oxygen tubing in the forward fuselage, lower forward flight deck, and lower forward cabin areas with new tubing. This must be done in accordance with the Accomplishment Instructions specified in Raytheon Service Bulletin SB 35-3406, dated March 2001, with different instructions for Model 400A and 400T series aeroplanes. The compliance section specifies that this action must be completed within 200 hours of time in service or one year from the effective date of the directive, whichever occurs first.
The obligations imposed by this AD on the parties it governs, primarily aircraft operators and maintenance organisations, are clear and specific. They must ensure that the identified Beechcraft 400 Series aeroplanes undergo the necessary replacement of low-pressure oxygen tubing as outlined in the requirement section. This involves adhering to the detailed instructions provided in SB 35-3406 and ensuring the replacement is carried out within the stipulated timeframe. Failure to comply with these obligations could compromise the safety of the aircraft and its occupants by potentially leading to oxygen leaks, lack of available oxygen for the flight crew, or other hazardous conditions such as explosions or fires.
Breach of the obligations set out in this AD can result in serious consequences, including both civil and criminal penalties. While the specific civil or criminal penalties are not detailed within this AD, non-compliance with airworthiness directives issued by the Civil Aviation Safety Authority (CASA) can generally lead to enforcement actions by CASA. These actions may include fines, suspension or revocation of airworthiness certificates, and other administrative penalties. In severe cases, particularly if non-compliance results in accidents or incidents, criminal charges could be brought against individuals or entities responsible for the breach, potentially leading to imprisonment. The exact penalties would depend on the specific circumstances and any relevant legislation, but the potential for significant legal repercussions underscores the importance of strict compliance with CASA directives.
