Service Life of MT Propellers
I am writing to correct a misapprehension that seems to be circulating about the TBO of MTV propellers used in aerobatics.
All these propellers have the service calendar life of six years between overhauls, and flying hours varying between 500 hours and 1,500 hours, depending on which prop and engine.
However if the aircraft is used only for "unlimited level competition flying" then the TBO is reduced to two years.
The practicality is this restriction will only apply to a small number of aircraft in the world.
For any other information about MT propellers do contact us.
