The TBO is a hard number for a Commercial operator. The Private operator can exceed it, and a Commercial operator can apply to the respective government for extensions. In Canada we can get a 10% extension, and Lycoming will allow another 10% if the engine is operated at least 40 hours per month. Or the engine can be operated "On Condition" for periods far longer than that but the maintenance and monitoring requirements go up. I think the FAA in the US will permit similar stuff.I must be rather ignorant on this subject,,, but...
I thought a "TBO" was just a suggestion from the manufacturer and not a "set" number mandated by the FAA to rebuild a motor
Who does one go to the "apply" for a TBO extension ? and
Who actually grants that extension ?
