Pratt & Whitney Canada (Booth No. 3718) announced that the time between overhaul (TBO) for PW206 and PW207 engines has been extended to 4,000 hours, from the original 3,500 hours. The TBO extension is applicable to engines incorporating certain service bulletins and to all new PW206 and PW207 engines. Alternatively, an engine upgrade is available to operators wanting to take advantage of the increased TBO interval. “This TBO extension will help operators derive more value from their engines,” said vice president of customer service Raffaele Virgili.
