COMMONWEALTH OF AUSTRALIA (Civil Aviation 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 revokes Airworthiness Directive (AD) AD/BEECH 50/23 Amdt 2 and issues the following 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.

 

Beechcraft 50 (Twin Bonanza) Series Aeroplanes

 

AD/BEECH 50/23

Amdt 3


Wing Front Spar 11/2000

 

 

Applicability: All models.

 

Requirement: Action in accordance with “Outboard Wing Main Spar Crack and Corrosion Inspection” in the Beechcraft Structural Inspection and Repair Manual 98-39006B3 as revised 28 May 1999, Chapter 57-10-00 Figure 208.

 

Compliance: Prior to exceeding 5 years from date of manufacture, and thereafter at intervals not exceeding 1 year.

 

Note: Aircraft already inspected in accordance with previous issues of this Directive, satisfy the initial inspection requirement of this issue.

 

This Amendment becomes effective on 2 November 2000.

 

Background: The original AD was issued in October 1973 and required inspection for corrosion in accordance with Beechcraft SI 0514-035. Amendment 1, issued in June 1973, reflected Revision 1 to the SI. Amendment 2 was raised in August 1990 to incorporate the use of the inspection method outlined in the Beechcraft Structural Inspection and Repair Manual, which supersedes Beechcraft SI 0514-035.

 

This Amendment results from a review of airframe ADs for the Beech heavy twin engine models, and updates the SIRM reference to reflect the current revision status. The inspections are ongoing but no additional work is required over and above the previous issue.


 

David Alan Villiers

Delegate of the Civil Aviation Safety Authority 21 September 2000


The above AD is notified in the Commonwealth of Australia Gazette on 4 October 2000.

Overview

The Civil Aviation Regulations 1998, as amended, are designed to ensure the safety and efficiency of civil aviation in Australia. One such legislative instrument, F2006B03947, pertains to the Civil Aviation Safety Authority (CASA) and the issuance of Airworthiness Directives (ADs). Specifically, AD/BEECH 50/23 Amdt 3 addresses safety concerns related to the Beechcraft 50 (Twin Bonanza) Series Aeroplanes, mandating inspections for wing front spar cracks and corrosion. This directive was enacted to rectify safety deficiencies identified through ongoing reviews and to ensure compliance with updated inspection methods. The objective is to maintain the airworthiness of these aircraft by mandating periodic inspections, thus reducing the risk of structural failure due to undetected cracks or corrosion.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39, outlines requirements for maintaining the airworthiness of aircraft within Australia. The legislation applies to all aircraft within the Commonwealth of Australia, encompassing both domestic and international flights, and mandates compliance with specific airworthiness directives (ADs) as issued by the Civil Aviation Safety Authority (CASA). In this instance, the AD/BEECH 50/23 Amdt 3 pertains to Beechcraft 50 (Twin Bonanza) Series aeroplanes, requiring all models to undergo specific inspections for wing front spar cracks and corrosion. The directive necessitates adherence to the inspection protocol outlined in the Beechcraft Structural Inspection and Repair Manual, ensuring that inspections occur before the aircraft exceeds five years from its date of manufacture and subsequently at intervals not exceeding one year. This regulatory framework is designed to maintain safety standards and ensure the operational integrity of the specified aircraft models.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39, Section 105, mandates the Civil Aviation Safety Authority (CASA) to issue Airworthiness Directives (AD) to ensure the safety of aircraft and aeronautical products. In this instance, AD/BEECH 50/23 Amdt 2 is revoked and replaced by AD/BEECH 50/23 Amdt 3, which pertains to the Beechcraft 50 (Twin Bonanza) Series Aeroplanes. This AD requires an inspection for cracks and corrosion in the outboard wing main spar, as detailed in the Beechcraft Structural Inspection and Repair Manual 98-39006B3, revised 28 May 1999. This inspection must be conducted before the aircraft exceeds five years from the date of manufacture and subsequently at intervals not exceeding one year. The obligations imposed by this AD are stringent and clear. Operators of Beechcraft 50 Series Aeroplanes must ensure that inspections are performed according to the specified instructions in the referenced manual. This includes detailed procedures outlined in Chapter 57-10-00, Figure 208 of the Beechcraft Structural Inspection and Repair Manual. For aircraft that have already undergone inspections in accordance with previous issues of this directive, the initial inspection requirement of the current directive is deemed satisfied. It is imperative that these inspections are meticulously carried out to maintain airworthiness standards and ensure the structural integrity of the aircraft. Failure to comply with the requirements of this Airworthiness Directive can lead to significant consequences. The Civil Aviation Regulations 1998 outline that non-compliance may result in the enforcement of penalties and sanctions. Although specific penalties are not detailed in the directive itself, under the broader regulatory framework, breaches of airworthiness directives can lead to civil penalties, including fines and potential criminal charges. The severity of these penalties can vary, but they are intended to enforce strict adherence to safety standards to protect public safety and maintain the integrity of the aviation system.
