The Citation Mustang PW615F engine has successfully completed its maiden flight. The 1.9 hour flight was flown on a CitationJet test bed from Cessna's Wichita, Kansas, facility. Cessna received the Citation Mustang PW615F engine from Pratt & Whitney Canada (P&WC) on April 1, 2004, and the first ground run test occurred on April 9. Since being delivered to Cessna, the PW615F engine has undergone approximately three hours of engine ground run evaluations. Prior to arriving at Cessna, it completed over 70 hours of testing at P&WC's engine test facilities. Cessna anticipates Mustang certification and first delivery in late 2006.
