Key Takeaways:
- Cessna 210 nose gear torque links are failing (bending or cracking), potentially due to excessive strut extension during landing.
- Diamond DA42 main landing gear downlock pins are repeatedly becoming unsecured due to failing circlips, causing aircraft damage, with a more permanent securing method suggested.
- ECI cylinders are exhibiting severe cracking, as seen in a Beech A36, underscoring the necessity of adhering to ECI's service bulletin for crack inspection.
- Champion Oil Filter CH48110-1 filters from a specific batch had manufacturing defects (element separation, debris) causing critical oil pressure and temperature issues shortly after installation.
