AD/FU24/42 - Installation of No Step Placard

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, serve as a comprehensive regulatory framework governing all aspects of civil aviation within the country. One particular legislative instrument under this Act is F2006B09989, which pertains to the airworthiness directives. This instrument was introduced to address specific safety concerns related to aircraft maintenance and operation. In this context, AD/FU24/42 is an airworthiness directive specifically targeting the FU 24 Series Aeroplanes manufactured by Airparts (NZ) Ltd. The directive mandates the installation of a "No Step" placard on each side of the fuselage above the aft half of the canopy rails. This requirement aims to enhance safety by preventing potential hazards associated with stepping on those areas of the aircraft. Compliance with this directive is necessary within 100 hours of time in service after 30 September 1971, ensuring that all relevant aircraft are promptly updated to meet the specified safety standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, apply to all airworthy aircraft operating within the Commonwealth of Australia. This includes aircraft registered in Australia, foreign aircraft registered in another country but operating within Australia, and Australian-registered aircraft operating overseas. The scope of this particular regulation pertains to Airparts (NZ) Ltd. FU 24 Series Aeroplanes, focusing on the installation of a “No Step” placard. This requirement applies to all models in the agricultural category. The directive mandates that a placard reading “NO STEP” with a minimum letter size of 1 inch must be installed on each side of the fuselage immediately above the aft half of the canopy rails. The compliance timeline necessitates that this installation be completed within 100 hours of time in service after 30 September 1971. This regulation does not extend its application through subordinate instruments and is specific to the mentioned aircraft models and the stated placard installation requirement.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives. One such directive, AD/FU24/42, pertains to the installation of a "No Step" placard on all models in the agricultural category of FU 24 Series Aeroplanes manufactured by Airparts (NZ) Ltd. (s. 1). According to this directive, the placard must be installed on each side of the fuselage, immediately above the aft half of the canopy rails, with the text "NO STEP" displayed in a minimum letter size of 1 inch (s. 2). The obligation imposed by this regulation is for the relevant entities, primarily Airparts (NZ) Ltd., to ensure that the specified placard is installed on the designated aircraft models. The directive mandates compliance within 100 hours of time in service after 30 September 1971 (s. 3). Failure to adhere to this requirement could potentially compromise safety standards, as the "No Step" placard serves to warn against stepping on the canopy rails, a critical safety measure in the operation of these aircraft. In terms of consequences for non-compliance, the Civil Aviation Regulations 1998 do not explicitly state offences, penalties, or civil/criminal consequences for breaching this specific directive. However, CASA has the authority to enforce compliance through various means, including issuing further directives, imposing fines, or even grounding the aircraft until the necessary modifications are made. The overarching aim is to maintain the highest safety standards in civil aviation, and thus, adherence to such directives is crucial to avoid any legal repercussions or safety risks.
