COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 106 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Teledyne Continental Motors Piston Engines
AD/CON/74 Turbocharger Oil Output Check Valve 7/95 DM
Applicability: All Teledyne Continental Motors (TCM) model TSIO-360-E, EB, F, FB, G, GB, KB, LB, MB and model LTSIO-360-E, EB and KB engines which have had a Dukes Incorporated turbocharger oil outlet check valve P/N 367-00 (TCM P/N 641068) installed or repaired on or after 1 August 1994.
Requirement: 1. Inspect the turbocharger oil outlet check valve (TCM P/N 641068) in accordance with Section B of TCM Critical Service Bulletin (CSB) 95-1, Revision A.
2. Replace valves which are identified with an ink stamp date code of A3Q94, A4Q94, A1Q95 or the date code is not readable, before further flight.
Note: FAA Airworthiness Directive 95-08-10 refers.
Compliance: Effective 10 May 1995; prior to further flight.
Background: This Directive has been issued to require an inspection of certain turbocharger oil outlet check valves. The requirement follows advice that certain oil outlet check valves were manufactured by Dukes Incorporated contrary to manufacturing specifications. Failure of affected valves could result in damage to the engine oil scavenge pump, internal engine damage and subsequent loss of engine power.
Overview
The Civil Aviation Regulations 1998, amended by F2006B08650, specifically address issues related to the airworthiness of Teledyne Continental Motors piston engines. This legislative instrument was enacted to address potential safety concerns associated with the turbocharger oil output check valve in certain TCM engines. The problem it targets is the risk of engine damage due to the failure of oil outlet check valves that were manufactured contrary to specifications, which could lead to severe consequences such as loss of engine power during flight. The Australian Government, through the relevant legislature, established this directive to ensure compliance with safety standards, thereby protecting public safety in aviation. The policy objective is to mandate the inspection and, if necessary, the replacement of the specified turbocharger oil outlet check valves to prevent potential engine failures.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 106, applies to all Teledyne Continental Motors (TCM) piston engines that have had a particular turbocharger oil outlet check valve installed or repaired since 1 August 1994. This regulation encompasses TCM model TSIO-360-E, EB, F, FB, G, GB, KB, LB, MB, and LTSIO-360-E, EB, and KB engines fitted with a Dukes Incorporated turbocharger oil outlet check valve P/N 367-00 (TCM P/N 641068). The regulation is enforced by the Civil Aviation Safety Authority and applies across the Commonwealth of Australia. The requirement for compliance is effective from 10 May 1995 and mandates that the specified valves be inspected and, if necessary, replaced before any further flight operations to prevent potential engine damage and loss of power. This regulation may be extended or restricted through subordinate instruments as required by the Civil Aviation Safety Authority.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 106 (Civil Aviation Safety Authority Schedule of Airworthiness Directives), mandate certain procedures for the inspection and replacement of turbocharger oil outlet check valves for specific Teledyne Continental Motors (TCM) engines. According to AD/CON/74 (7/95 DM), all TCM model TSIO-360-E, EB, F, FB, G, GB, KB, LB, MB and LTSIO-360-E, EB, and KB engines that have had a Dukes Incorporated turbocharger oil outlet check valve P/N 367-00 installed or repaired on or after 1 August 1994 must comply with certain requirements (Section 1). The primary requirement is to inspect the turbocharger oil outlet check valve (TCM P/N 641068) in accordance with Section B of TCM Critical Service Bulletin (CSB) 95-1, Revision A (Section 1). Furthermore, any valves identified with an ink stamp date code of A3Q94, A4Q94, A1Q95 or those with an illegible date code must be replaced before any further flight (Section 2). This directive is particularly important as it references FAA Airworthiness Directive 95-08-10 and is designed to prevent potential damage to the engine oil scavenge pump and internal engine damage, which could lead to loss of engine power.
The obligations imposed by the regulations on the parties governed by this Act are quite clear. Engine operators, owners, and maintenance personnel must ensure that the inspection and replacement requirements are strictly adhered to. This includes conducting a thorough inspection of the specified turbocharger oil outlet check valves in line with the TCM Critical Service Bulletin 95-1, Revision A. Should any valves be identified as needing replacement due to their date codes or illegibility, these must be replaced before the engine is operated again. Failure to comply with these requirements could result in significant safety risks, including potential engine failure mid-flight.
The Civil Aviation Regulations 1998 do not explicitly outline specific offences, penalties, or consequences for non-compliance with these airworthiness directives. However, non-compliance with airworthiness directives issued by the Civil Aviation Safety Authority (CASA) can lead to severe repercussions under broader aviation safety legislation. Non-compliance could result in the grounding of aircraft, fines, and even criminal charges if the non-compliance leads to accidents or incidents. The exact penalties and consequences would be determined by CASA and could potentially include hefty fines, suspension or revocation of airworthiness certificates, and criminal charges for those responsible, depending on the severity of the breach and its impact on aviation safety.
