AD/BEECH 77/5 - Control Column Installation

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, are a comprehensive set of rules that govern civil aviation safety. Part 39 of these regulations includes Airworthiness Directives, which are legally enforceable rules related to the design, construction, maintenance, and operation of aircraft. One such directive, AD/BEECH 77/5, addresses the installation of control columns in Beechcraft 77 (Skipper) Series aeroplanes. This directive was introduced to address the specific problem of the pilot's or co-pilot's foot being caught forward of the control column floor console, which could potentially lead to safety issues during flight. The policy objective of this directive is to ensure that all affected aircraft are modified in accordance with the specified requirements to eliminate this hazard. Compliance with this directive is mandatory for all model 77 aircraft with serial numbers ranging from WA-2 to WA-80, and must be completed before 1 November 1980.

Scope and Application

The Civil Aviation Regulations 1998, as amended, apply comprehensively to the operation and maintenance of aircraft within Australia, including the issuance of specific Airworthiness Directives (ADs) such as AD/BEECH 77/5. This particular directive pertains to all Beechcraft 77 (Skipper) Series Aeroplanes with serial numbers WA-2 to WA-80. The directive is issued under the authority of the Civil Aviation Safety Authority (CASA) and aims to address safety concerns related to the control column installation, particularly the risk of a pilot's or co-pilot's foot becoming entrapped forward of the control column floor console. Compliance with this directive is mandatory for the specified aircraft, requiring adherence to the action outlined in Beechcraft Service Information (SI) No. 1124 before 1 November 1980. This regulatory requirement is integral to ensuring the safety standards of aviation operations within Australia's jurisdiction.

Key Provisions

The main operative sections of AD/BEECH 77/5 pertain to the installation of control columns in Beechcraft 77 (Skipper) Series Aeroplanes with serial numbers WA-2 to WA-80. This directive, outlined in section 105 of the Civil Aviation Regulations 1998, requires that all applicable aircraft must comply with the action specified in Beechcraft Service Instruction (SI) No. 1124. The directive necessitates that these actions be completed before 1 November 1980 to ensure safety and compliance with civil aviation standards. The obligations imposed by this Airworthiness Directive are specific to the aircraft model and serial number range mentioned. Owners or operators of these Beechcraft 77 (Skipper) Series Aeroplanes must adhere to the instructions provided in Beechcraft SI No. 1124. This typically involves inspecting and potentially modifying the control column installation to prevent any risk of a pilot's or co-pilot's foot being caught forward of the control column floor console. Ensuring compliance with these directives is critical for maintaining the airworthiness of the aircraft and the safety of all onboard personnel. Failure to comply with the provisions of AD/BEECH 77/5 can result in serious consequences. The Civil Aviation Safety Authority (CASA) enforces these directives, and non-compliance can lead to enforcement actions. While the specific penalties are not detailed within the directive itself, the broader regulations under the Civil Aviation Act 1988 and associated regulations can impose significant civil or criminal penalties. These may include fines, suspension or revocation of the aircraft's certificate of airworthiness, and potential criminal charges if the non-compliance leads to accidents or fatalities. The exact penalties will depend on the severity of the non-compliance and any resultant harm.
