AD/VW/1 - Assurance Inspection

Overview

The Civil Aviation Regulations 1998, as amended, contain a specific Airworthiness Directive aimed at enhancing the safety of Volkswagen derivative piston engines used in aviation. Known as AD/VW/1, this directive was enacted to address the issue of non-type certificated Volkswagen derivative engines exhibiting significant component and assembly defects, which had been discovered in engines submitted for approval for use in amateur-built aircraft. The objective of this legislation is to ensure that all such engines are inspected, assembled, and tested by an approved individual to mitigate safety risks. This directive is issued under the authority of the Civil Aviation Safety Authority and aims to maintain high safety standards in the aviation sector by ensuring that these engines meet stringent inspection and assembly requirements before being installed in aircraft.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives Volkswagen Derivative Piston Engines Assurance Inspection AD/VW/1 applies specifically to all non-type certificated Volkswagen derivative engines intended for use in aircraft. The directive mandates that before such engines can be assembled for installation in an aircraft, they must undergo a rigorous inspection process conducted by an individual approved by the Secretary. This requirement is underpinned by the need to ensure that all engine components are inspected in accordance with data approved by the Secretary, which includes a mandatory magnetic particle inspection on the crankshaft and connecting rod bolts. Additionally, the engines must be assembled and tested by an approved person, and permanently identified with a serial number that reflects the identity of the engine builder or manufacturer. The serial number and compliance with this directive must be endorsed in the engine log book. Compliance with these directives is mandatory for engines with zero time since new or overhaul, as well as those removed from an aircraft for major maintenance or for installation in another aircraft. This directive ensures that all VW derivative engines meet stringent safety standards before being used in aviation, thereby mitigating risks associated with component defects and assembly procedure errors.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 106, addresses the airworthiness directives for Volkswagen derivative piston engines through the Airworthiness Directive AD/VW/1. This directive outlines the requirements for ensuring the safety of these engines before they are installed in aircraft (AD/VW/1). The key requirement is that all non-type certificated Volkswagen derivative engines must undergo an assurance inspection before being assembled for installation (AD/VW/1(1)). This inspection must be carried out by a person approved by the Secretary, and all engine components must be inspected according to data approved by the Secretary (AD/VW/1(2)). Additionally, a magnetic particle inspection must be performed on the crankshaft and connecting rod bolts unless this has already been done (AD/VW/1(3)). The engine must be assembled and tested according to the approved data, by an approved person, and must be permanently identified with a serial number that includes the identity of the engine builder or manufacturer (AD/VW/1(4) and (5)). The engine's serial number and compliance with this directive must be endorsed in the engine logbook (AD/VW/1(6)). The directive imposes specific obligations on the parties involved. Owners or operators of non-type certificated Volkswagen derivative engines must ensure that the engines comply with the inspection, assembly, and testing requirements outlined in AD/VW/1. This includes ensuring that the engines are inspected by an approved person, that all components are inspected according to approved data, and that any necessary magnetic particle inspections are carried out. Furthermore, the engines must be assembled and tested by an approved person, and they must be permanently identified with a serial number that includes the identity of the engine builder or manufacturer. Additionally, the engine serial number and compliance with AD/VW/1 must be recorded in the engine logbook. There are no specific offences, penalties, or civil or criminal consequences mentioned for non-compliance with AD/VW/1 in the provided text. However, non-compliance with airworthiness directives can result in serious safety risks, potentially leading to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions may include grounding of the aircraft, fines, or other regulatory measures to ensure compliance and safety. The exact penalties would depend on the specific circumstances of the non-compliance and the regulatory framework in place at the time of the violation.
