AD/CESSNA 320/10 Amdt 3 - Fuel System - Placards

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve to regulate various aspects of civil aviation operations within the country. One specific legislative instrument, F2006B08189, pertains to Airworthiness Directives for the Cessna 320 Series Aeroplanes, particularly focusing on fuel system placards. This directive was introduced to address safety concerns by ensuring that pilots are clearly informed about the minimum fuel requirements and operational parameters. The policy objective here is to enhance flight safety by providing clear and prominent warnings regarding fuel levels and power settings during descent, thereby reducing the risk of accidents due to fuel mismanagement. The Civil Aviation Safety Authority has established this directive to mandate the installation of specific placards within the aircraft to ensure pilots are constantly aware of critical fuel thresholds and operational limits. The requirement stipulates that a placard must be placed near the main fuel quantity indicator, prohibiting operation with less than five gallons of fuel in each main tank, and another near the manifold pressure gauge, advising to maintain power within green arcs during descent. This proactive measure aims to mitigate risks associated with inadequate fuel awareness and improper power settings, ultimately contributing to overall aviation safety.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives for Cessna 320 Series Aeroplanes, applies to all model 320 and 320-1 aircraft with serial numbers ranging from 320-0001 to 320-0110. This regulation is enforced at the national level under the Commonwealth of Australia and is applicable across all states and territories within Australia. The regulation mandates the placement of specific placards to ensure the safe operation of these aircraft, detailing the operational restrictions and requirements for maintaining power within designated green arcs during descent. The regulation permits operators to create and certify the installation of these placards, provided they adhere to the stipulated letter size of a minimum height of one eighth inch. The regulation does not explicitly mention any exclusions or exemptions, but it does include a compliance date, specifying that the requirements must be met before 1 September 1971. The scope of the regulation may be further refined or expanded through subordinate instruments, but the primary directive remains the installation and visibility of the specified placards for the safety of pilots and passengers.

Key Provisions

The key operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, include requirements for the installation of placards on Cessna 320 series aeroplanes (sections 39-105 and AD/CESSNA 320/10). These placards are intended to provide critical operational information to pilots, enhancing safety during flight. Section 39-105 mandates that a placard stating "Operation With Less Than Five (5) Gallons of Fuel In Each Main Tank is Prohibited. Usable Fuel In Each Tank Is 45 Gallons" must be placed in full view of the pilot and as close as possible to the main fuel quantity indicator. Additionally, another placard stating "Maintain Power Within Green Arcs During Descent" must be positioned in full view of the pilot and near the manifold pressure gauge. Operators have the flexibility to produce and certify these placards themselves, with a requirement for the letters to be a minimum of one-eighth inch in height. The Civil Aviation Regulations impose several obligations on the parties governed by these provisions. Operators of Cessna 320 series aeroplanes must ensure that the specified placards are installed according to the outlined requirements. This includes positioning the placards in locations that are easily visible to the pilot and close to relevant gauges. Furthermore, operators are responsible for ensuring that the placards meet the specified height requirement for the letters, ensuring that the information is legible and clear. Compliance with these obligations is crucial for maintaining the safety standards set forth by the Civil Aviation Safety Authority. Failure to comply with the placarding requirements stipulated in the Civil Aviation Regulations can result in various consequences. While the specific legal text does not detail penalties, non-compliance with regulations enforced by the Civil Aviation Safety Authority can lead to enforcement actions. These actions may include fines, sanctions, or other regulatory measures to ensure compliance. In serious cases of non-compliance, there could be additional civil or criminal consequences, depending on the severity and impact of the breach on aviation safety. It is therefore imperative for operators to adhere strictly to the placarding requirements to avoid any potential repercussions.
