Only one was found cracked. The submitter believes landing impact with more than the recommended strut extension (five inches maximum), according to the service manual. Strut extension is adjusted by adding shims (p/n 1243618-2.)

Assorted Failures

Key Takeaways:
- Cessna 210 nose gear torque links are experiencing bending and cracking, suspected to be caused by landing impacts with excessive strut extension.
- Diamond DA42 main landing gear downlock pins are repeatedly becoming unsecured due to circlip failures, leading to structural damage and suggesting a need for more permanent securing methods.
- A severe circumferential crack in an ECI cylinder head caused significant engine vibration and eventual cylinder separation in a Beech A36, underscoring the relevance of ECI's Mandatory Service Bulletin 06-2.
- A new Champion oil filter (CH48110-1) failed due to element separation, causing debris to enter the engine system, resulting in critically low oil pressure and high oil temperature.
