Fifty years after delivering its very first engine to Beechcraft, Pratt & Whitney Canada celebrated another milestone yesterday by delivering to Beechcraft at EAA AirVenture the 80,000th PT6 turboprop, in this case a -60A variant that powers the King Air 350i. “As we are celebrating the 50th anniversary of this iconic engine,” said P&WC president John Saabas, “we are proud to share this important moment with Beechcraft, which was the first customer to select the PT6.” The PT6 has since become the most popular engine in all aviation market segments.
