Overview

The Civil Aviation Safety Regulations 1998, specifically within Part 39, address various safety directives to ensure the airworthiness of aircraft in Australia. Enacted by the Commonwealth of Australia, these regulations were introduced to fill the gap in maintaining safety standards in the civil aviation sector. One such directive, AD/BEECH 300/17 from 2003, pertains to the Beechcraft 300 series aeroplanes, aiming to correct unsafe conditions identified in the exterior door operating procedures. The directive was issued by the Civil Aviation Safety Authority (CASA) delegate, David Alan Villiers, to ensure compliance with the improved operating instructions as recommended by the National Transportation Safety Board, thereby enhancing emergency response capabilities during critical situations.

Scope and Application

The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, outlines the scope and application of the Civil Aviation Safety Authority's (CASA) Airworthiness Directives, which mandate safety measures and procedures to ensure the safe operation of aircraft. This particular AD/BEECH 300/17 applies to specific Beechcraft 300 series aeroplanes, namely Model 300 aircraft with serial numbers ranging from FA-1 to FA-230, Model B300 aircraft from FL-1 to FL-252, and Model B300C aircraft from FM-1 to FM-9 and FN-1. The directive requires modification of the exterior door operating procedures to incorporate the applicable kit as specified in Raytheon Mandatory Service Bulletin SB 52-3096 Revision 1, which was issued in June 2002. The requirement must be met within 200 hours of time in service or within 12 calendar months from 17 April 2003, whichever is earlier, unless the modification has already been completed. The directive becomes effective on 17 April 2003 and is applicable across the Commonwealth of Australia, with the AD published in the Commonwealth of Australia Gazette on 26 March 2003.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CAR 1998) establish various rules and directives aimed at ensuring the safety of aircraft in Australian airspace. In particular, Part 39 of these regulations pertains to Airworthiness Directives, which are mandatory instructions issued to address safety issues identified in specific aircraft models. For instance, AD/BEECH 300/17 (Section 39.1(1)) specifically targets the Beechcraft 300 Series Aeroplanes, requiring modifications to the exterior door operating procedures. The directive applies to Model 300 aircraft, Model B300 aircraft, and Model B300C aircraft within specified serial number ranges (Section 39.1(2)). Under the AD/BEECH 300/17 directive, the requirement is to modify the exterior door operating procedures by incorporating an applicable kit in accordance with the instructions provided in Raytheon Mandatory Service Bulletin SB 52-3096 Revision 1, Revised: June 2002 (Section 39.1(3)). The Compliance section mandates that this action be taken within 200 hours of time in service or 12 calendar months after 17 April 2003, whichever occurs first, unless the modification has already been completed (Section 39.1(4)). This directive became effective on 17 April 2003. The obligations imposed by the AD/BEECH 300/17 on the parties involved include ensuring that the specified modifications are carried out by the deadline mentioned in the compliance section. Failure to comply with the Airworthiness Directive could result in significant safety risks, particularly in emergency situations where the door or emergency exits might not function as intended. The directive is a response to an accident investigation conducted by the National Transportation Safety Board, which recommended improved exterior operating instruction placards following an incident involving the Model 1900 airstair door. Breach of the requirements set out in the AD/BEECH 300/17 can lead to serious consequences. Non-compliance with Airworthiness Directives is generally considered a serious offence under the Civil Aviation Act 1988. Civil penalties for failing to adhere to these directives can be substantial, and in severe cases, criminal charges may be brought against the responsible parties. The maximum penalties for such breaches are not explicitly detailed in the AD itself but are governed by broader aviation safety legislation, which can include fines and imprisonment.
