AD/BEECH 90/32 - Elevator Stop Bolts - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, govern a multitude of facets related to civil aviation safety and operations. Specifically, Part 39 - 105 of these regulations addresses Airworthiness Directives (ADs), which are legally enforceable rules that aim to ensure the continued airworthiness of aircraft. The introduction of these regulations was crucial in establishing a comprehensive framework to address potential safety risks and to maintain the highest safety standards in Australian airspace. One such Airworthiness Directive, AD/BEECH 90/32, pertains to the modification of elevator stop bolts in Beechcraft 90 and 65-90 (King Air) series aeroplanes to ensure continued safety and compliance with airworthiness standards. The policy objective of these regulations is to mandate that all applicable aircraft meet specific safety requirements, thereby mitigating risks and ensuring the safety of passengers and crew.

Scope and Application

The Civil Aviation Safety Authority (CASA) Regulations 1998, specifically Part 39 - 105, encompasses the Schedule of Airworthiness Directives for various aircraft types, including the Beechcraft 90 and 65-90 (King Air) series aeroplanes. This particular legislative instrument, AD/BEECH 90/32, pertains to the modification of elevator stop bolts for specific models of the King Air series. The directive applies to all C90 models with serial numbers ranging from LJ-552 to LJ-588 and all E90 models with serial numbers from LW-1 to LW-56. This regulation aims to ensure the airworthiness of these aeroplanes by mandating compliance with the specified modifications within 100 hours’ time in service following the directive's effective date of 30 September 1974. The directive is referenced in Beechcraft Service Instruction No. 0618-152, which provides further details on the required modifications to ensure adherence to safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, detail a series of Airworthiness Directives (AD) aimed at ensuring the safety of aviation operations within Australia. One such directive, AD/BEECH 90/32, focuses on Beechcraft 90 and 65-90 (King Air) series aeroplanes, particularly addressing elevator stop bolts (Section 105). This directive mandates modifications to the elevator stop bolts on specific models to ensure their safe operation. The directive applies to all models C90 with serial numbers (S/Nos.) ranging from LJ-552 to LJ-588 and all models E90 with S/Nos. from LW-1 to LW-56. Compliance with this directive is required within 100 hours of time in service after 30 September 1974, as specified in Beechcraft SI No. 0618-152. The obligations imposed by AD/BEECH 90/32 require the operators of affected aircraft to ensure that the specified modifications to the elevator stop bolts are carried out by authorised personnel. This involves a thorough inspection and, if necessary, the replacement or adjustment of the elevator stop bolts to meet the safety standards set forth in the directive. Operators must also maintain records of the modifications and inspections to demonstrate compliance with the regulations. Failure to adhere to these requirements can result in the aircraft being deemed non-airworthy, thereby prohibiting its operation until the necessary modifications are completed. Breaching the requirements set out in AD/BEECH 90/32 can lead to significant legal consequences. Under the Civil Aviation Regulations 1998, non-compliance can result in both civil and criminal penalties. Civil penalties may include fines and the potential grounding of the affected aircraft. Criminal penalties can be imposed if the non-compliance is deemed to have caused a risk to safety, potentially leading to imprisonment for the responsible individuals or entities. The exact penalties depend on the severity of the breach and the specific circumstances, but they are designed to enforce strict adherence to safety regulations to protect public safety.
