TBO Extension, which provides FAA-certified engine life extension solutions for business aircraft, is expecting FAA authorization to expand its engine-life extension supplemental type certificate (STC) to include the Pratt & Whitney Canada (P&WC) PW530A and PW535A engines, which power the Cessna Citation Bravo and Encore, respectively.

The Atlantic Jet Partners subsidiary’s STC modification for the P&WC JT15D—which powers several legacy Citations, along with the Beechjet 400A/Hawker 400XP—has been installed on more than 200 engines as a cost-effective alternative to OEM overhaul. It has added more than 2,000 hours of flight service life per engine and significantly reduced ownership costs.
