Mooney SIM20-92 Owner's manual

  • Hello! I've reviewed the service instruction regarding the replacement of the torsion spring in the drive clutch assembly of GEC (Plessey) landing gear actuators for specific Mooney aircraft models, including M20J, M20K, M20M, and M20L series. The document specifies compliance at 1000 flight hours and references GEC Service Instruction SI-11. I am ready to help you with any questions you might have about the document or the procedure.
  • What is the subject of this service instruction?
    What is the required time of compliance?
    Which models are affected by this instruction?
    Where can I find the detailed instructions?
