AD/BEECH 90/45 - Wing Strobe Lights - Replacement

Overview

The Civil Aviation Regulations 1998, as part of Australia's legislative framework for aviation safety, were enacted by the Parliament of Australia to ensure the safety of civil aviation operations within the country. One specific aspect of this regulatory scheme is addressed in Part 39 - 105, which outlines the requirements for airworthiness directives, including those specific to particular aircraft models. This legislation aims to fill the gap in maintaining the safety standards of aircraft by ensuring that all aircraft in operation comply with specific safety directives, such as the replacement of wing strobe lights for certain models of Beechcraft aeroplanes. The Civil Aviation Safety Authority (CASA) enforces these directives to achieve the overarching policy objective of ensuring the safety and reliability of civil aviation activities within Australia. The particular airworthiness directive, AD/BEECH 90/45, focuses on the replacement of wing strobe lights for Beechcraft 90 and 65-90 (King Air) series aeroplanes with specific serial numbers, as identified in the directive. This measure was introduced to address safety concerns associated with the existing wing strobe lights, specifically those with Hoskins P/N 30-0187-21 or Grimes P/N 30-0669-1. The directive mandates compliance within 100 hours’ time in service after the issuance date, 29 October 1976, ensuring that affected aircraft meet the required safety standards to operate safely in Australian airspace. This legislative instrument underscores the commitment to maintaining high safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, mandates that all Beechcraft 90 and 65-90 (King Air) series aeroplanes, including models B90 and C90 with serial numbers LJ-318 through LJ-502, and model E90 with serial number LW-1, must comply with the airworthiness directive AD/BEECH 90/45 if they are equipped with either Hoskins part number 30-0187-21 or Grimes part number 30-0669-1 wing strobe lights. The directive requires the replacement of these wing strobe lights, and compliance must be achieved within 100 hours’ time in service after the directive was issued on 29 October 1976. This regulation applies to aeroplanes within the specified serial number range, ensuring that the mandated modifications are implemented to maintain the required safety standards. The directive is enforceable under the authority of the Civil Aviation Safety Regulations and is designed to address potential safety issues associated with the specified wing strobe lights.

Key Provisions

The key provisions of the Civil Aviation Regulations 1998, specifically within Part 39 - 105, focus on ensuring the airworthiness of certain aircraft models. Section AD/BEECH 90/45 mandates the replacement of wing strobe lights on Beechcraft 90 and 65-90 (King Air) Series Aeroplanes. This applies to all models B90 and C90 with serial numbers ranging from LJ-318 to LJ-502 and the E90 model with serial number LW-1, provided they are equipped with either Hoskins part number 30-0187-21 or Grimes part number 30-0669-1 wing strobe lights. The directive references Beechcraft Service Information (SI) No. 0800-362 and requires compliance within 100 hours of time in service after 29 October 1976. The obligations under this legislation require the aircraft operators or owners to ensure that the specified wing strobe lights are replaced as per the directive. This involves adhering to the guidelines set forth in the referenced Beechcraft SI No. 0800-362, ensuring that the aircraft meet the necessary safety standards. Operators must ensure that the replacement is carried out by qualified personnel and that the aircraft is not operated beyond the stipulated timeframe without compliance. Failure to adhere to these requirements can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can lead to civil penalties. Specifically, the maximum penalty for an individual can be up to $22,200, and for a corporation, the penalty can be up to $111,000. Additionally, persistent non-compliance or operation of an aircraft that does not meet airworthiness standards can result in criminal charges, leading to potential imprisonment. The severity of these consequences underscores the importance of timely compliance with airworthiness directives to maintain the safety and legality of aviation operations.
