AD/BEECH 33/6 - Fuel System - Placards

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, were introduced to establish comprehensive safety regulations in the aviation industry, addressing gaps in ensuring the airworthiness of aircraft and the safety of passengers, crew, and the public. One specific legislative instrument under this Act is the AD/BEECH 33/6, which pertains to the Beechcraft 33 and 35-33 (Debonair/Bonanza) series aeroplanes. This directive aims to enhance flight safety by mandating specific placards in the aircraft's fuel system. The policy objective is to ensure that pilots are clearly informed about operational restrictions related to take-offs and prolonged slips to prevent potential fuel system issues, thereby reducing the risk of accidents. Compliance with these airworthiness directives is mandatory, with a requirement to implement the changes within 100 hours of the aircraft being in service after the directive's effective date of 29 April 1970.

Scope and Application

The Civil Aviation Regulations 1998, as detailed in Part 39 - 105, govern the safety standards for civil aviation in Australia, with specific airworthiness directives addressing particular aircraft types and issues. One such directive, AD/BEECH 33/6, pertains to the Beechcraft 33 and 35-33 (Debonair/Bonanza) series aeroplanes, specifically targeting models 35-33, 35-A33, 35-B33, 35-C33, E33 and F33 with specified serial numbers, along with certain other models and serial numbers, unless retrofitted with anti-slosh main fuel tanks. This directive applies to both the owner and operator of these aircraft, mandating compliance within 100 hours of time in service after 29 April 1970. The directive requires the installation of a specific placard on the instrument panel, readable by the pilot, prohibiting certain types of manoeuvres to prevent fuel system issues. Additionally, it necessitates the removal of an existing placard that may conflict with the new safety instructions. The regulations are administered under the Commonwealth of Australia and are enforceable across the nation, with compliance monitored by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, detail the safety directives for the Beechcraft 33 and 35-33 (Debonair/Bonanza) series aeroplanes, focusing on fuel system placards as outlined in AD/BEECH 33/6 (4/70). The regulations mandate that a specific placard must be installed on the instrument panel in a location clearly visible to the pilot. This placard must include the text: "TURNING TYPE TAKE-OFFS AND TAKE-OFF IMMEDIATELY FOLLOWING FAST TAXI TURN PROHIBITED. AVOID PROLONGED SLIPS (20 SECONDS OR MORE) WITH FUEL TANKS LESS THAN HALF FULL." The owner or operator is permitted to manufacture and certify this placard for installation, ensuring that the letters are at least one eighth inch in height. The regulations impose certain obligations on the parties involved. The owner or operator of the affected aircraft must ensure that the specified placard is installed within 100 hours of the aircraft's time in service after April 29, 1970. Additionally, if the aircraft is equipped with another placard stating: "CAUTION - to prevent fuel flow interruption due to gravity or centrifugal force, select the high-wing tank in slips and inside tank during turning take-offs," it must be removed. These steps are crucial to maintaining compliance with the safety directives set forth by the Civil Aviation Safety Authority. Failure to comply with these requirements can result in various consequences. While the specific legal penalties are not detailed within the text, non-compliance with Civil Aviation Regulations can lead to enforcement actions by the Civil Aviation Safety Authority, including fines, sanctions, and potential grounding of the aircraft. Such actions are intended to ensure the safety of the aircraft and its passengers, underscoring the importance of adhering to the specified safety directives.
