AD/G73/22 - Elevator Control System

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, such as AD/G73/22, which pertains to Frakes (Grumman) G73 Series Aeroplanes. This legislative instrument was enacted to address the problem of elevator control system jamming in the full nose-up position during take-off, as reported overseas. The aim of this directive is to ensure the safety and airworthiness of the affected aircraft models by requiring compliance with Frakes Aviation S.B. G-73-FA26, with a noted reference to FAA AD 8-25-08. This regulation was introduced by the Commonwealth of Australia to mandate corrective actions prior to 30 March 1988 to mitigate safety risks associated with the identified issue.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, mandate the application of Airworthiness Directives (AD) which are crucial for maintaining the safety standards of aircraft operations within the Commonwealth of Australia. For the Frakes (Grumman) G73 Series Aeroplanes, AD/G73/22 pertains to the elevator control system and applies to all models of this aircraft series. This regulation requires compliance with Frakes Aviation S.B. G-73-FA26, referencing FAA AD 8-25-08, and mandates that corrective actions be taken prior to 30 March 1988 to address the reported issue of the elevator control system jamming in the full nose-up position during take-off. This directive ensures that all operators of these aircraft within Australian airspace adhere to the specified safety measures, thus upholding the stringent safety standards set forth by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, includes a directive pertaining to Frakes (Grumman) G73 Series Aeroplanes, designated as AD/G73/22 (1). This directive addresses the Elevator Control System, with a requirement that action must be taken in accordance with Frakes Aviation S.B. G-73-FA26 (2). This directive is also referenced in FAA AD 8-25-08 (3), highlighting its relevance and importance in ensuring aircraft safety. This legislation applies to all models of the Frakes (Grumman) G73 Series Aeroplanes (4). The directive mandates that the elevator control system must be addressed to prevent the occurrence of jamming in the full nose-up position, particularly during take-off, as reported overseas (5). Compliance with this directive is required prior to 30 March 1988 (6). The urgency of this directive underscores the necessity for immediate action to mitigate potential risks associated with the identified safety issue. Entities governed by this Act, including aircraft manufacturers, operators, and maintenance providers, must adhere to the outlined requirements (7). They are obligated to implement the specified actions in accordance with Frakes Aviation S.B. G-73-FA26 to ensure the elevator control system is safe and operational (8). This includes conducting necessary inspections, repairs, or modifications to prevent the aforementioned jamming issue, thereby maintaining the airworthiness of the aircraft. Failure to comply with the provisions of AD/G73/22 may result in serious safety hazards and could lead to civil or criminal consequences (9). While specific penalties are not detailed in the text, non-compliance with airworthiness directives can generally result in substantial fines, imprisonment, or both, depending on the severity of the breach and its impact on aviation safety (10). The overarching aim of these penalties is to enforce strict adherence to safety regulations and to protect the public from potential harm arising from non-compliance.
