TBO increased to 3,600 hours or 6 years

After reaching another milestone with 130 flying Silent-7 propellers, several propellers were inspected based on the certification requirements after 2,000 hours in service. The propellers showed basically no wear or abnormalities. Due to these excellent inspection results, the engineering team at MT-Propeller was able to increase the TBO for the 7-bladed propellers - presently installed on the Pilatus PC-12 series, the King Air 350 series and the Short Skyvan - to 3,600 hours or 6 years, whichever comes first.





The TBO for MT-Propeller’s 7-bladed Silent-7 props, which are currently used on aircraft such as the Pilatus PC-12 and the King Air 350 series, has now been increased to 3,600 hours or six years.
