AD/BEECH 90/29
Amdt 3
Applicability: All models.
Wing Front Spar 11/2000
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, Chapters 57-13-01 Figure 209, 57-13-02 Figure 204, 57-13-03 Figure 201, or 57-14-01 Figure 201, as applicable to individual aeroplanes.
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, comply with the initial inspection requirement of this issue.
This Amendment becomes effective on 2 November 2000.
Background: The original of this Airworthiness Directive was issued in October 1973 and required inspection for corrosion in accordance with Beechcraft SI 0514-035.
Amendment 1 was issued in June 1973 and reflected Revision 1 to the SI.
Amendment 2 was issued in August 1990. It incorporated the use of the inspection method outlined in the Beechcraft Structural Inspection and Repair Manual, which superseded Beechcraft SI 0514-035.
COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
This Amendment results from a review of airframe ADs for the Beech heavy twin engine models. The SIRM reference has been updated to the current revision status, and references to specific SIRM chapter and figure numbers have been added to correctly identify the intended corrosion inspection requirement. The inspections are ongoing but no additional work is required over and above the previous issue.

Delegate of the Civil Aviation Safety Authority 22 September 2000
The above AD is notified in the Commonwealth of Australia Gazette on 4 October 2000.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, is a comprehensive framework designed to ensure the safety and efficiency of civil aviation within Australia. One of the critical components of this regulatory body is the Civil Aviation Safety Authority (CASA), which is responsible for overseeing the safety standards and compliance of aircraft operations. The problem this legislation addresses is the need for stringent and updated safety protocols to mitigate risks associated with aircraft operations. The objective is to ensure that aircraft maintain an acceptable level of safety through continuous oversight and the issuance of specific directives, as evidenced by the Airworthiness Directive (AD) for Beechcraft 90 and 65-90 (King Air) aeroplanes. This AD, issued under the authority of CASA, aims to mandate specific inspection requirements to address structural integrity issues, thereby enhancing overall aviation safety.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105 within the Civil Aviation Safety Authority Schedule of Airworthiness Directives, addresses safety standards and requirements for the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. This Airworthiness Directive (AD) applies to all models of the specified aircraft and mandates specific actions to rectify identified unsafe conditions. The directive necessitates inspections for corrosion and cracks in the wing front spar, with detailed instructions provided in the Beechcraft Structural Inspection and Repair Manual 98-39006B3. The inspections must be conducted before the aircraft exceeds five years from its date of manufacture and at intervals not exceeding one year thereafter. The directive does not exclude any aircraft from its scope, but it does provide that those already inspected in line with previous directives comply with the initial inspection requirements of the new issue. The AD is applicable across the Commonwealth of Australia, aligning with national aviation safety standards set by the Civil Aviation Safety Authority. Any further specifications or modifications to the AD can be made through subordinate instruments, ensuring that safety protocols remain current and effective.
Key Provisions
The Civil Aviation Regulations 1998, under Part 39 - 105, establish the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives (AD) for specific aircraft models, including the Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. Section 39.105 (1) of the CAR 1998 provides the authority for issuing such ADs to ensure that the aircraft maintain a high standard of airworthiness. The AD in question, AD/BEECH 90/29 Amdt 3, pertains to all models of the Beechcraft 90 and 65-90 series aeroplanes. Specifically, it mandates inspections for corrosion and cracks on the wing front spar. The requirement for these inspections is outlined in "Outboard Wing Main Spar Crack and Corrosion Inspection" in the Beechcraft Structural Inspection and Repair Manual 98-39006B3, as revised on 28 May 1999. The inspection must be conducted before the aircraft exceeds five years from the date of manufacture and then at intervals not exceeding one year thereafter.
The AD imposes several obligations on the operators and maintainers of the affected aircraft. Firstly, they must ensure that the specified inspections are carried out in accordance with the detailed instructions provided in the referenced Beechcraft Structural Inspection and Repair Manual. This includes following the correct procedures for identifying and addressing any corrosion or cracks on the wing front spar. The manual provides specific figures and chapters, such as 57-13-01 Figure 209, 57-13-02 Figure 204, 57-13-03 Figure 201, and 57-14-01 Figure 201, which should be used to guide the inspection process. Additionally, operators must maintain records of all inspections and any corrective actions taken, ensuring compliance with the regulatory requirements.
Failure to comply with the AD can lead to serious consequences. The Civil Aviation Regulations 1998 provide for both civil and criminal penalties for non-compliance with ADs. Civil penalties may include fines up to the maximum prescribed by the regulations, while criminal penalties may result in imprisonment, depending on the severity and frequency of the non-compliance. The exact penalties can vary based on the specific circumstances of the breach but are designed to enforce strict adherence to airworthiness standards. Non-compliance not only poses a risk to the safety of the aircraft and its occupants but also to the broader aviation community. Therefore, operators must take the AD seriously and ensure that all required inspections and corrective actions are performed in a timely and effective manner.
