AD/CESSNA 170/26 - Front Seat Restraint Installation

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, form a comprehensive regulatory framework governing civil aviation in Australia. One specific piece of legislation under this framework is the Airworthiness Directive AD/CESSNA 170/26, introduced to address safety concerns related to the front seat restraint installation in Cessna 170, 172, F172, FR172 and 175 series aeroplanes. This directive was established to ensure that all such aircraft models must modify their front seat restraint installations by fitting a safety harness in accordance with a scheme approved by the Secretary. The objective of this directive is to enhance the safety of pilots and passengers by mandating the installation of approved safety harnesses, with compliance required before 1 September 1972.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the safety directives for certain Cessna aeroplanes, including the 170, 172, F172, FR172, and 175 series. This legislation applies to all models within these series and mandates that each front seat restraint installation must be modified by fitting a safety harness approved by the Secretary. Compliance with this directive is required before 1 September 1972, ensuring that all affected aircraft meet the specified safety standards. This regulatory requirement underscores the Civil Aviation Safety Authority’s commitment to enhancing the safety of aviation operations through stringent maintenance and modification protocols for critical aircraft components. The scope of the Act is geographically broad, applying across the Commonwealth of Australia, thereby ensuring uniform safety standards are enforced nationally.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 105, include a directive concerning the airworthiness of certain Cessna aeroplanes. This directive, AD/CESSNA 170/26, pertains to the installation of safety harnesses in the front seats of Cessna 170, 172, F172, FR172, and 175 series aeroplanes. The requirement outlined in Section 105 is that each front seat restraint installation must be modified to fit a safety harness. This modification must adhere to a scheme approved by the Secretary. The directive applies to all models within the specified series, ensuring a standardised safety measure across the board. The obligations imposed by this Act are clear and direct. Operators of the aforementioned Cessna aeroplanes must ensure that the front seat restraints are modified in accordance with the approved safety harness scheme before 1 September 1972. This compliance date provides a clear timeline for operators to undertake the necessary modifications, ensuring that all aircraft meet the specified safety standards by the stipulated date. Failure to adhere to this requirement could potentially compromise the safety of the aircraft and its occupants, highlighting the importance of timely compliance. In terms of penalties and consequences, the Civil Aviation Regulations 1998 do not explicitly state penalties for non-compliance with this particular directive in the provided text. However, non-compliance with airworthiness directives generally can result in severe consequences. These may include grounding of the aircraft, fines, or other regulatory actions taken by the Civil Aviation Safety Authority (CASA). The exact penalties and consequences would be determined based on the severity and impact of the non-compliance, but it is clear that adherence to these safety standards is mandatory and non-compliance could lead to significant repercussions.
