AD/INST/11 - Automatic Pilot Servo Actuators - Inspection

Overview

The Civil Aviation Regulations 1998, as amended by the Civil Aviation (Automatic Pilot Servo Actuators - Inspection) Instrument 2006 (F2006B10812), aim to enhance the safety of civil aviation by mandating regular inspections of specific automatic pilot servo actuators. This legislative instrument was enacted to address the problem of potential failures in certain automatic pilot servo actuators, which could lead to significant safety risks. The policy objective behind these regulations is to ensure the continued airworthiness of aircraft by identifying and rectifying potential issues with the specified components. Enacted by the Commonwealth of Australia, this regulation falls under the purview of the Civil Aviation Safety Authority, which oversees the implementation and enforcement of these safety measures to protect passengers and crew in the national airspace.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 107, pertains to the safety directives issued by the Civil Aviation Safety Authority concerning airworthiness. The regulation in question, AD/INST/11, mandates the inspection of automatic pilot servo actuators of certain types and serial numbers, namely Type PA500A below S/No. 3000, Type PA520A below S/No. 2800, and Type PA520B below S/No. 1500, if they do not feature a white dot painted adjacent to or on the actuator nameplate. This directive applies to all aircraft operators who possess or operate such specified automatic pilot servo actuators, ensuring compliance to maintain the safety standards required by the Civil Aviation Safety Authority. The geographic reach of this regulation is national, applying across the Commonwealth of Australia and enforced under the purview of federal civil aviation laws. Compliance must be achieved within 100 hours of the aircraft's time in service after the directive's effective date of 28 June 1974, as referenced in documents such as Cessna Avionics SL AV 74-3 and ARC SB No. 171, or FAA AD 74-08-01. This regulation is a pivotal component in the broader framework of civil aviation safety, ensuring that automatic pilot systems adhere to specified standards to prevent malfunctions and ensure the safety of flights within Australian airspace.

Key Provisions

The Civil Aviation Regulations 1998, particularly under Part 39 - 107 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives, have specific requirements concerning automatic pilot servo actuators. Section AD/INST/11 addresses these, focusing on the inspection of certain automatic pilot servo actuators. Specifically, it applies to Automatic Pilot Servo Actuators Type PA500A below serial number 3000, Type PA520A below serial number 2800, and Type PA520B below serial number 1500, unless they have a white dot painted adjacent to or on the actuator nameplate. The directive requires compliance with either document 1, Cessna Avionics SL AV 74-3 and ARC SB No. 171, or document 2, FAA AD 74-08-01. Compliance is mandatory within 100 hours of time in service after 28 June 1974. Under these regulations, the key obligations for the parties involved include ensuring that the specified automatic pilot servo actuators are inspected according to the outlined directives. Owners and operators of aircraft equipped with these actuators must ensure that the inspections are carried out as stipulated within the timeframes specified, which is within 100 hours of time in service following the date of the directive. Compliance with either Cessna Avionics SL AV 74-3 and ARC SB No. 171, or FAA AD 74-08-01, is mandatory, and failure to adhere to these directives could result in non-compliance with the Civil Aviation Regulations. Failure to comply with these airworthiness directives can lead to significant consequences. The legislation does not explicitly state the exact penalties or consequences for non-compliance, but non-compliance with Civil Aviation Regulations generally can result in severe penalties. These may include fines, enforcement actions, or even the grounding of aircraft until the necessary inspections are performed and compliance is achieved. The severity of the penalties can depend on the specific circumstances of the non-compliance, but the overarching principle is that adherence to these directives is crucial to maintaining airworthiness and safety standards.
