XAC MA60

TYPE: Twin-turboprop airliner.

PROGRAMME: Model of MA60 as proposed Y7-200A (PW127 turboprop) variant first shown at Asian Aerospace, Singapore, February 2000. First flight (prototype B-995L) reportedly 12 March 2000; CAAC type certificate issued 22 June 2000; revenue service began August 2000; public debut (Airshow China) November 2000; production certificate issued 12 December 2000.
Designation indicates Modern Ark, 60 (high density) seats. To replace earlier Y-7 variants, which from 2001 no longer meet amended Chinese airworthiness requirements. XAC production capacity 12 to 15 a year; domestic operators will lease from central leasing agency SFLC, which will be responsible for sole-source marketing (first arrangement of this kind in China).

CURRENT VERSIONS: MA60: Initial production passenger version; as described. Current life-cycle of 25,000 landings and 30,000 flight hours.
MA60-100: Improvements planned for introduction in 2002 included reduction in empty weight by about 400 kg (882 lb); increase in 'hot-and-high' MTOW of about 900 kg (1,984 lb); increase in OEI ceiling; 162 n mile (300 km; 186 mile) increase in range; airframe drag reduction; Rockwell Collins Pro Line 21 avionics upgrade.
MA60H-500: Updated MA60 equivalent of former Y7H, with rear-loading ramp/door inherited from An-26. Fully pressurised cargo compartment, with electric winch and hydraulic conveyor; cargo door can be retracted under belly to permit direct loading from truck or ground. Available from 2004. Demonstrator bears CFTE serial number 073.
MA60-MPA (Fearless Albatross): Projected maritime patrol version (previously Y7-200BF); nose-mounted search radar; raked wingtips; auxiliary fuel tanks scabbed to fuselage sides to extend range to estimated 1,350 n miles (2,500 km; 1,553 miles); four underwing stations for air-to-air and anti-ship missiles. Shown as model at Airshow China, November 2000.
MA40: Shortened (40-passenger) version; under consideration in 2002.

CUSTOMERS: Sole-source domestic marketing by newly formed Shenzhen Finance Leasing Corporation which, on 7 November 2000, signed contract for delivery of 60 MA60s over five-year period. Launch operator Sichuan Airlines (five ordered, plus five on option) introduced first leased example (B-3426) into revenue service August 2000. Other reported orders by March 2003 from Changan Airlines (two), China Northern (five), Wuhan Airlines (three) and Lao Aviation (three). Of these 18, six said to be in airline operation at that time. Most of first 60 expected to be of improved MA60-100 standard.

COSTS: Approximately US$11 million (2002).

DESIGN FEATURES: Further upgrade of Y-7 series, mainly through Western engines and avionics and improved passenger comfort; incorporates best features of earlier Y7-200A and B programmes. Airframe life 40,000 hours, 25,000 cycles or 25 years.
