The FAA is proposing to adopt a new airworthiness directive (AD) for certain Pratt & Whitney Canada PT6A engines. The proposed AD was prompted by in-service events involving the perforation of engine cases as a result of the liberation of power-turbine blades and the fracture/displacement of the power-turbine containment ring.

The KA90 engine update kit is an engine alternative to improve King Air 90 performance. It allows the option of installing either a set of PWC PT6A-21, -28, or -34 engines to replace the original PT6A-20 engines. According to Greg Barnes, president of CenTex Aerospace, of Waco Regional Airport in Waco, Texas, “The KA90 engine update kit allows the flexibility to choose new, overhauled or engines with time remaining as replacements. Any of the three engine models will improve takeoff, climb and cruise performance.”

Brazil’s civil aviation authority, Agência Nacional de Aviação Civil (ANAC), approved Blackhawk’s XP42A performance upgrade for the Cessna 208A Caravan. ANAC’s certification follows similar approval from the FAA in June that permits the engine upgrade on the Cessna 208A in the U.S. The XP42A mod includes a new 850-shp Pratt & Whitney Canada PT6A-42A; Hartzell four-blade propeller; composite cowling; high-efficiency inlet duct; larger oil cooler; and two new exhaust stacks. Blackhawk claims the package increases climb rate by 24 percent and cruise speed by 9 percent.
Both Tawazun and Mubadala are displaying models of the new maritime patrol aircraft (MPA) version of the Piaggio Avanti that is under development for Adasi, a Tawazun subsidiary. Piaggio Aero, in which Mubadala has a large stake, is developing the aircraft platform with a long-span wing and increased foreplane and tailplane area, among other changes. Sweden’s Saab has been employed to provide the mission system. The MPA will be operated by a crew of four, comprising a pilot, two sensor/system operators and a mission commander.

There were two major developments in the business turboprop sector this year and neither involved new aircraft. However, they did show where potentially the next growth area is for the turboprop market: downstream. Turboprops historically have been a useful vehicle for introducing new customers into the corporate aircraft market, provided operators can maintain price discipline. If not, bad things can happen. Case in point: after several years of public struggle, Piaggio Avanti fractional provider Avantair ceased operations in June.
Pratt & Whitney Canada (P&WC) has committed to a new agreement with Hawker Beechcraft Services to support its engines on both Beechcraft King Air twin turboprops and Hawker business jets.
