StandardAero has received supplemental type certification (STC) to remove Pratt & Whitney Canada PT6A-41 or -42 series engines on the Beechcraft King Air 200/200C/B200/B200C and replace them with PT6A-52 engines and four-blade Hartzell propellers. It is the same engine and propeller combination that is type certified on the new Beechcraft King Air B200GT. With this STC approval StandardAero becomes the third company in the world to hold an STC for the modification.
Manny Atwal, general manager of StandardAero’s turboprop business, said the company is also the only PT6A designated overhaul facility that can offer customers maintenance, repair and overhaul as well as PT6 engine upgrade options.
PT6A-41 and -42 engines have been in service for more than 35 years, and many of those engines are approaching their third and fourth overhaul, said Atwal. “Low cycle fatigue replacement, service bulletin requirements and customer build specifications are driving up the overhaul and maintenance costs. With the StandardAero engine-upgrade program, customers can get a new PT6A-52 engine for a slightly higher cost than overhauling their aging PT6A-41 or -42 engines, while increasing performance and aircraft value.”
Upgrading to the StandardAero PT6A-52 engine program provides Beechcraft King Air 200-series operators with the updated P&WC engine technology and increased performance with 300-plus knots true airspeed in cruise. StandardAero also offers extended warranty coverage to 10 years or base time before overhaul. StandardAero’s designated alternation station (DAS) in Springfield, Ill., was instrumental in receiving this approval.
