Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 106, includes an Airworthiness Directive concerning AlliedSignal (Lycoming) Turbine Engines of the LTS 101 series. Enacted to address potential safety issues stemming from manufacturing discrepancies, this directive was introduced to ensure the integrity and safety of aircraft engines by mandating the replacement of the number 2 bearing. The objective of this regulation is to prevent bearing failure and consequent engine failure, thereby enhancing aviation safety. The directive applies to LTS101 series engines that incorporate the specified number 2 bearing, as detailed in Textron Lycoming Alert Service Bulletin Number A-LT101-72-50-0163 Revision 1. The directive was made effective on 2 March 1995, aligning with the requirements outlined in the referenced alert service bulletin and the Federal Aviation Administration's Airworthiness Directive 94-18-06.
Scope and Application
The AlliedSignal (Lycoming) Turbine Engines - LTS 101 Series AD/LTS/10 applies specifically to LTS101 series engines that include the Number 2 Bearing with the part number 4-301-362-01, as identified by their serial numbers in Textron Lycoming Alert Service Bulletin Number A-LT101-72-50-0163 Revision 1. This regulation is issued under the Civil Aviation Regulations 1998, which are overseen by the Civil Aviation Safety Authority (CASA) in Australia, and thus apply throughout the Commonwealth. The directive mandates the replacement of the number 2 bearing in accordance with the aforementioned service bulletin. This requirement follows concerns about potential manufacturing discrepancies that could lead to bearing failure and, subsequently, engine failure. The directive is effective from 2 March 1995, aligning with the compliance details specified in the requirement document. While the directive itself sets out the mandatory replacement of bearings, further specifications and compliance details are available in the referenced Textron Lycoming Alert Service Bulletin and the FAA Airworthiness Directive 94-18-06.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 106, include a Schedule of Airworthiness Directives, which detail mandatory safety requirements for various aircraft components. Section AD/LTS/10 pertains to the AlliedSignal (Lycoming) Turbine Engines LTS 101 Series, focusing on the Number Two Bearing. The applicability of this directive is defined for LTS101 series engines that include the Number 2 Bearing P/N 4-301-362-01, as detailed by serial numbers in Textron Lycoming Alert Service Bulletin Number A-LT101-72-50-0163 Revision 1. The requirement is to replace the number 2 bearing in accordance with the referenced alert service bulletin. The directive also notes the relevance of the FAA Airworthiness Directive 94-18-06 for further context.
The obligations under this directive include ensuring that the number 2 bearing in the specified LTS101 series engines is replaced as per the instructions in Textron Lycoming Alert Service Bulletin No. A-LT101-72-50-0163 Revision 1. This involves identifying the affected engines, sourcing the correct replacement bearing, and performing the replacement in accordance with the detailed procedures outlined in the bulletin. The directive is effective from 2 March 1995, and compliance is mandatory for all affected aircraft operators and maintenance personnel.
Failure to comply with the requirements of this directive can result in significant legal and safety consequences. The main objective of issuing this directive is to mitigate the risk of bearing failure and subsequent engine failure, which could potentially lead to serious accidents. Civil Aviation Safety Authority (CASA) enforces these directives rigorously, and non-compliance can result in penalties. The specific penalties are not detailed in the text, but they typically include fines and possible grounding of non-compliant aircraft until the directive is met. The severity of the consequences reflects the importance of ensuring that all airworthiness directives are strictly adhered to for the safety of all passengers and crew on board.
