Hi everyone. In a Rotax powered acft., if an owner has installed a Hobbs meter and changed the logged hours from Total time to Hobbs / Tach, and started using the new Tach / Hobbs with a difference of about 100Hrs between them: 1-Is there a way to legally / properly correct it? 2-How does that affect the Airworthiness of the acft.? 3-Will that force a conversion of that acft. from SLSA to ELSA? 4-What are the consequences of doing that? Thank you.
