AD/TBM 700/2 - Elevator Horn Anti-Icing

Overview

The Civil Aviation Regulations 1998, specifically within Part 39 - 105, contain the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. The legislative instrument F2006B07367 addresses the Aerospatiale (Socata) TBM 700 Series aeroplanes, particularly focusing on elevator horn anti-icing. Enacted by the Australian Parliament, this regulation was introduced to address the critical safety issue of ice accumulation on the elevator horns of the specified aircraft, which can compromise flight safety during low-speed operations and in icing conditions. The policy objective is to mandate the installation of pneumatic de-icing equipment, as outlined in Socata TBM SB 70-20-30, to ensure the airworthiness of these aircraft and protect against the risks posed by ice build-up on the elevator horns. Compliance with this directive is required prior to 30 June 1993, as referenced in GAC AD 93-041(B).

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to Aerospatiale (Socata) TBM 700 Series aeroplanes with serial numbers 1 to 49 inclusive, mandating the installation of pneumatic de-icing equipment to the elevator horns to prevent ice accumulation during low-speed flight and in icing conditions. The regulations are applicable nationally under the Commonwealth of Australia, ensuring that these aircraft meet specific safety standards. The compliance requirement was effective prior to 30 June 1993, and the action must be taken in accordance with Socata TBM Service Bulletin SB 70-20-30, with reference to GAC AD 93-041(B). This legislation extends its application through subordinate instruments, ensuring that all relevant aviation safety directives are adhered to for the specified aircraft series.

Key Provisions

The key sections of the Civil Aviation Regulations 1998, Part 39 - 105 (Civil Aviation Safety Authority Schedule of Airworthiness Directives), specifically concerning the Aerospatiale (Socata) TBM 700 Series Aeroplanes, are notably AD/TBM 700/2, which mandates elevator horn anti-icing measures (Section 6/93). This directive applies to all Aerospatiale TBM 700 Series aircraft with serial numbers ranging from 1 to 49 inclusive. The requirement is for the aircraft to be modified in accordance with the Socata TBM Service Bulletin SB 70-20-30, referencing the GAC AD 93-041(B). This regulation necessitates the installation of pneumatic de-icing equipment to the elevator horns to prevent ice accumulation, particularly at low speeds and in icing conditions. The obligations imposed by this legislation on the relevant parties are to ensure that the specified modifications are implemented on the Aerospatiale TBM 700 Series aircraft. Owners, operators, and maintenance providers must comply with the requirements outlined in the Socata TBM Service Bulletin SB 70-20-30 and the referenced GAC AD 93-041(B). Compliance must be achieved before the deadline of 30 June 1993. This involves the installation of the specified de-icing equipment to the elevator horns, which is essential for maintaining airworthiness and safety standards in the given operational conditions. Failure to comply with the requirements set out in AD/TBM 700/2 may result in various consequences. Civil Aviation Safety Authority (CASA) regulations outline potential penalties for non-compliance. While the specific penalties are not detailed within this directive, the general consequences for breaching Civil Aviation Regulations can include fines, suspension or revocation of airworthiness certificates, and potential criminal charges. The severity of the penalties may depend on the degree and impact of non-compliance, as well as any resulting safety risks. Operators and owners are, therefore, strongly advised to adhere to the prescribed modifications to avoid these repercussions.
