COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Robin Aviation Series Aeroplanes
AD/ROBIN/30
Amdt 1
Engine Air Intake Inspection 1/2000
Applicability: Robin aircraft as detailed by model in Robin Aviation Service Bulletin No. 161 Revision 1.
Requirement: 1. As applicable by aircraft model, inspect the interior of the air intake box and carburettor heat deflector plate in accordance with the requirements of Process 1 of Robin Aviation Service Bulletin No. 161 Rev. 1.
2. As applicable by aircraft model, inspect the interior of the air intake laminated air ducting, including the area located downstream of the intake air filter, in accordance with the requirements of Process 2 of Robin Aviation Service Bulletin No. 161 Rev. 1.
Note: DGAC Airworthiness Directives 1999-053(A) and 1999-470(A) refer.
Compliance: Effective 31 December 1999: Unless previously accomplished; within 5 hours time in service and thereafter at intervals not to exceed 110 hours time in service.
This Amendment becomes effective on 31 December 1999.
Background: This directive was originally issued to require an inspection of the interior of the engine air intake box for evidence of paint detaching. Paint detaching from the interior of the air intake box and inlet duct may result in a loss of engine power or engine stoppage. This amendment reflects the manufacturer’s revision to the requirement document. The revision, in part, adds a requirement to inspect the ducting between the air filter and the air intake box.
Overview
The Civil Aviation Regulations 1998, as amended by the Legislative Instrument F2006B06629, specifically within Part 39 - 105, addresses the need for the inspection of the air intake systems of Robin Aviation Series Aeroplanes. This legislation was introduced to enhance safety within the aviation industry by ensuring that aircraft maintain their airworthiness through regular and specified inspections. The regulation is enforced by the Civil Aviation Safety Authority (CASA) and aims to mitigate the risk of engine power loss or stoppage due to paint detaching from the air intake box and inlet duct. The amendment, which became effective on 31 December 1999, reflects updates from the manufacturer's service bulletins, further detailing the inspection processes and intervals required to maintain compliance with airworthiness directives.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate the applicability and requirements for the airworthiness of Robin Aviation Series aeroplanes, as detailed in the Civil Aviation Safety Authority's schedule of airworthiness directives. This legislation applies to all Robin aircraft models as specified in Robin Aviation Service Bulletin No. 161 Revision 1, requiring specific inspections to ensure the continued airworthiness of these aircraft. The requirement mandates an inspection of the interior of the air intake box and carburettor heat deflector plate, as well as the laminated air ducting downstream of the intake air filter, following the outlined processes in the referenced service bulletin. These inspections are imperative to prevent potential engine performance issues such as loss of power or engine stoppage, which may arise from paint detaching within the air intake system. The directive applies nationally across Australia, governed under the Commonwealth of Australia's regulatory framework for civil aviation safety. Compliance with this airworthiness directive is mandatory, with inspections needing to be completed within five hours of time in service and thereafter at intervals not exceeding 110 hours of time in service, effective from 31 December 1999. This directive aligns with previous DGAC Airworthiness Directives 1999-053(A) and 1999-470(A).
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39 - 105, mandate specific airworthiness directives for certain aircraft types, including Robin Aviation Series Aeroplanes. This legislative instrument, AD/ROBIN/30 Amendment 1 from 2000, outlines the requirements for inspecting the engine air intake systems of these aircraft to ensure safety and performance standards are met (Section 1). The directive applies to the aircraft models detailed in Robin Aviation Service Bulletin No. 161 Revision 1 (Section 2). It requires inspections of the interior of the air intake box and the carburettor heat deflector plate, as well as the interior of the air intake laminated air ducting, including the area downstream of the intake air filter, in accordance with specific processes outlined in the service bulletin (Section 1).
The obligations imposed by this directive are clear and precise. Operators of Robin Aviation Series Aeroplanes must conduct the specified inspections to ensure that the air intake systems are free from issues such as paint detaching, which could compromise engine performance (Section 1). The inspections must be performed within 5 hours of the aircraft's time in service and thereafter at intervals not exceeding 110 hours of time in service. This requirement aims to maintain the airworthiness of the aircraft and prevent potential engine failures (Section 3). Compliance with these inspection schedules is mandatory to ensure continued airworthiness and adherence to safety standards.
Failure to comply with the inspection requirements set forth in this directive can lead to serious consequences. The regulations do not explicitly state the penalties for non-compliance in the excerpt provided, but non-compliance with airworthiness directives generally can result in enforcement actions by the Civil Aviation Safety Authority (CASA). Such actions could include fines, suspension of the aircraft's airworthiness certificate, or other regulatory measures that could affect the operational status of the aircraft (Section 4). Ensuring adherence to these directives is crucial to maintaining the safety and reliability of the aircraft in operation.
