AD/LEARJET/7 - Emergency Exit Window, Seat-Back Operating Instruction Placard - Installation

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, were established to regulate civil aviation safety across the country, ensuring the safety and security of the nation's airspace. Among these regulations, Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives includes specific directives for maintaining the airworthiness of aircraft. The aim of these directives is to address identified safety issues and ensure that all aircraft meet the necessary safety standards to operate legally within Australian airspace. One such directive is AD/LEARJET/7, which pertains to Gates Learjet 24 & 25 Series Aeroplanes and requires the installation of a specific placard above the cabin emergency exit window. This directive was introduced to address the need for clear and unambiguous instructions for passengers in the event of an emergency exit operation. The requirement is for a placard stating “PUSH SEAT-BACK FORWARD TO CLEAR EXIT” in a minimum of 3/16" high red lettering on a white background. Compliance with this directive was mandated before 30 June 1975, underscoring the importance of timely implementation to enhance passenger safety during emergencies.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, which governs the safety standards and requirements for aircraft in Australia. This regulation applies to all Gates Learjet 24 & 25 Series Aeroplanes and mandates the installation of a specific placard above the cabin emergency exit window to ensure passengers are adequately informed about the emergency exit procedures. The requirement is that a placard stating "PUSH SEAT-BACK FORWARD TO CLEAR EXIT" in red on a white background, with a minimum lettering height of 3/16", must be installed by 30 June 1975. This regulation is applicable nationwide, ensuring a consistent safety standard across all states and territories. The directive is clear and specific, leaving little room for interpretation, and applies uniformly to all aircraft within the specified series without any exclusions or exemptions.

Key Provisions

The key provisions of AD/LEARJET/7 revolve around the installation of a specific placard for Gates Learjet 24 & 25 Series Aeroplanes. Section 3/75 of the Civil Aviation Regulations 1998 mandates that a placard be installed above the cabin emergency exit window, immediately below the existing window operating instruction placard. The placard must contain the instruction "PUSH SEAT-BACK FORWARD TO CLEAR EXIT". The regulation specifies that the lettering on this placard must be a minimum of 3/16 inches high, in red on a white background. This requirement applies to all models within the Gates Learjet 24 & 25 Series. The obligations imposed by this directive are straightforward. Operators and owners of Gates Learjet 24 & 25 Series Aeroplanes must ensure that the specified placard is installed correctly and complies with the detailed requirements. This includes adhering to the prescribed dimensions and colour specifications for the lettering and background. Failure to comply with these requirements could result in the aircraft not meeting the necessary safety standards and thus being deemed non-airworthy. Breaches of the Civil Aviation Regulations 1998, including failure to adhere to Airworthiness Directives such as AD/LEARJET/7, can lead to serious consequences. The Act imposes penalties for non-compliance, which may include fines and other civil penalties. Additionally, operating an aircraft that does not comply with airworthiness directives can result in criminal charges. The severity of the penalties depends on the nature and extent of the breach, but they can be significant, reflecting the importance of adhering to safety standards in civil aviation.
