856 FLIGHT International, 23 November 1967 The long-bodied FH-227 COMMERCIAL AIRCRAFT SURVEY on the FH-227B transmit 5 per cent more thrust during take-off and climb, and lead to a 15 per cent greater useful load than the earlier model. Both of the stretched aircraft have provision for the later fitment of RDalO Darts. The FH-227B was certificated in mid-1966 and is in service with three American local-service airlines and one trunk-route carrier. FH-227B Orders: Mohawk, 13; Northeast, 7; Ozark, 12; Pied-mont, 4. Total, 36 (all delivered). , ..:-: F-228 On February 1 Fairchild Hiller announced its long-awaited plans to build a short-haul jet to suit the American regional airlines—an estimated market of 250 aircraft. Designated simply F-228, the aircraft is a 50-seat shorter-bodied version of the 60-seat Fokker F.28 Fellowship with the new-generation high-by-pass Rolls-Royce RB .203-01 Trent as the powerplant, in place of the Spey Junior in the F.28. The F-228 also differs in having triple-slottedflaps in an attempt to get an even higher Gr, max. West Coastwas the first airline to put the F-27 into service, and it is first again with an order for F-228s. The manufacturer has an initialbatch of 50 aircraft in hand. Production of the F-228 will be under a co-operative contract between Fairchild Hiller and Fokker acting together with Euro- pean partners HFB, VFW and Shorts. The F-228 will use the F-28 tailcone and empennage made by VFW, components of the fuselage built by Fokker and HFB, and a portion of the wing structure made by Shorts. Some of the same systems will be used. The first parts have already been shipped across the Atlantic, and the first F-228 is expected to fly on October 1 next year. The terms of the Fokker/Fairchild Hiller contract call for the F-228 and the F.28 to be sold in parallel—by the latter in the Western Hemisphere, and by Fokker in the rest of the world. The Rolls-Royce RB.203 Trent is being developed as a private venture, though it benefits from government-funded research into high-by-pass engines, and by being modelled on the gas-generator components of the RB.172 Adour turbojet for the Anglo-French Jaguar military strike aircraft. The Trent embodies the advanced philosophies for greater efficiency, reduced noise and low cost that have gone into the RB.207 (airbus powerplant) and RB.211 (pro- posed for L-1011 and DC-10). The first run is imminent and flight engines will be delivered to America next summer. No indication has been given of the selling price of the F-228, though this will obviously be a critical factor. The manufacturers say that on a 100-mile sector the aircraft will have a direct operating cost per mile of $1.34 compared with $1.1 of an FH-227B. The comparative seat-mile costs are: 2.66 cents (50-seat F-228) and 1.97 cents (56-seat FH-227B). To achieve such parity with advanced turboprop aircraft marks a notable advance in turbofan airliner technology and would suggest good prospects for sales of the F-228, which is roughly two-thirds the size of the One-Eleven/ DC-9/737 bracket yet is claimed to be able to offer direct operating costs per aircraft-mile some 25 per cent less than these aircraft.
