Stay informed about the FAA Airworthiness Directive effective December 5, 2024
Learn how this directive impacts your Lycoming engines and how ALS aviation oil analysis can help you meet requirements
In light of the new FAA Airworthiness Directive (AD) effective December 5, 2024, we want to inform you of an important update to our ALS aviation oil analysis program. The FAA Airworthiness Directive (AD) addresses a safety concern involving Lycoming engines with specific connecting rod assemblies that could be prone to failure, which may result in in-flight shutdowns or uncontained engine failures. Download our technical summary.
As part of the FAA’s efforts to mitigate this risk, operators are required to perform repetitive oil inspections for bronze metal particulates, which can indicate degradation of the engine's connecting rod bushings. The FAA Airworthiness Directive (AD) mandates if bronze particulates are found, additional inspections must be carried out to assess the condition of the connecting rod bushings and, where necessary, replace the bushings.
To support our clients in meeting the requirements of this new directive, ALS is adding the following elemental tests to our AOA program regardless of engine type:
- Tin
- Molybdenum
- Lead
- Magnesium
- Chromium
These tests will help detect the presence of critical metal particulates that could signal potential issues with connecting rod bushings. By incorporating these elements into our program, we aim to ensure that you are able to comply with the new FAA AD if needed, while also supporting the safe operation and maintenance of your Lycoming engines.
We recommend that you begin scheduling oil inspections in preparation for the implementation of the FAA Airworthiness Directive (AD). We are committed to providing you with the tools and support necessary to help maintain the highest standards of airworthiness and safety.
