AD/SEATS/2 - Enviroform Fibreglass/Kevlar Reinforced Seats

Overview

The Civil Aviation Regulations 1998, as amended, are a comprehensive set of rules governing civil aviation in Australia. Part 39, in particular, addresses the maintenance and airworthiness of aircraft, including the issuance of airworthiness directives. One such directive, AD/SEATS/2, pertains to Enviroform Fibreglass/Kevlar Reinforced Seats, particularly those used in certain Cessna aircraft models. Enacted to address safety concerns and ensure the continued airworthiness of these specific seats, the directive was introduced by the Civil Aviation Safety Authority, the body responsible for overseeing aviation safety in Australia. The overarching policy objective is to mitigate risks associated with the use of these seats, thereby enhancing the safety of air travel. Compliance with this directive is mandatory, requiring actions to be taken within a specified timeframe to ensure that the seats meet the required safety standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 – 107, apply to the maintenance and safety of aircraft seats within Australia's jurisdiction. This regulation encompasses all Enviroform fibreglass/Kevlar reinforced seats, which are predominantly installed in certain Cessna aircraft models, including the C.402B and C, C.404, C.421C, C.F406, and C.441, within specified serial numbers. The requirement outlined in AD/SEATS/2 mandates compliance with actions detailed in Cessna MEB 87-9, CAB 87-16, or CQB 87-5. Compliance must be achieved within 100 hours of time in service following 24 March 1988. These seats, initially subject to AD/CESSNA 400/50 in 1977, have since been retrofitted to other aircraft, and the scope of applicability has expanded as Cessna continues to modify these seats. The regulation applies to these specific seats and aircraft within the Australian jurisdiction, ensuring that the airworthiness directives are adhered to for safety purposes.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 107, detail the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives which mandate that certain aircraft seats meet particular safety standards. The relevant section, AD/SEATS/2, addresses Enviroform fibreglass/Kevlar reinforced seats. This directive applies to all Enviroform seats, which are normally fitted to specific Cessna aircraft models as outlined in the document (s. 3). These aircraft include the C.402B and C.402C (s. 3), C.404 (s. 3), C.421C (s. 3), C.F406 (s. 3), and C.441 (s. 3), each with specific serial number ranges. The directive requires that action be taken in accordance with Cessna Maintenance Engineering Bulletin (MEB) 87-9, Cessna Airworthiness Bulletin (CAB) 87-16, or Cessna Quality Bulletin (CQB) 87-5 (s. 3). The primary obligation imposed by this regulation is that the specified seats must comply with the action items detailed in the referenced bulletins within 100 hours of time in service after 24 March 1988 (s. 3). This timeframe is critical for ensuring that any potential safety issues are addressed promptly to maintain the airworthiness of the aircraft. The regulation underscores the importance of adherence to these directives to ensure the structural integrity and safety of the seats in question. Failure to comply with these airworthiness directives can result in significant consequences. The Civil Aviation Regulations do not explicitly state the penalties for non-compliance in this particular section; however, non-compliance with CASA directives generally can lead to severe repercussions. This may include civil penalties, enforcement actions, and potentially criminal charges if the non-compliance results in a safety incident. The penalties for such breaches could range from substantial fines to imprisonment, depending on the severity and impact of the non-compliance. It is essential for operators and maintainers to ensure strict adherence to these directives to avoid these severe consequences.
