originally to be mounted on the aft fuselage, however during the course of design work their location was moved to under the high-mounted wing. Early flights were to be undertaken with General Electric CJ610 engines fitted. Development continued after Fairchild acquired the company, but the project was shut down nine weeks from first flight. It was later cut up as scrap and the fuselage used as a Metro display at trade shows. At the 1987 Paris Air Show, Fairchild released details of proposed developments of the Metro designated the Metro V and Metro VI. These versions would have featured a longer fuselage with a taller "stand-up" cabin providing of interior height for passengers; a redesigned, longer wing; engines moved further out on the wing from the fuselage; a "T-tail" and various system improvements. A Merlin V corporate version of the Metro V was also planned. The Metro V was to be fitted with the same engines as the Metro 23 and the Metro VI was to be fitted with more powerful TPE331-14 engines. The Metro VI was shelved within months of being announced due to a lack of customer interest, but Fairchild did not proceed with the Metro V either. One version that did see the light of day was the Metro 25, which featured an increased passenger capacity of 25 at the expense of the baggage space found in earlier models; the deletion of the left rear cargo door, the addition of a passenger door on the right-hand rear fuselage, and a belly pod for baggage. A Metro III was converted as a Metro 25 demonstrator, it flew in this configuration in October 1989. Also mooted but not built was the Metro 25J, which would have been another jet-powered aircraft with TFE731s in over-wing pods. The type certificates for Metro and Merlin aircraft are currently held by M7 Aerospace. Operational history Two of the original Metro model were delivered in 1972 to Société Minière de Bakwanga (MIBA) in Kinshasa, Zaire, the first customer to put the Metro into service. The first airline to put them into service was Commuter Airlines in January 1973, followed shortly after by Air Wisconsin. At least one Metro IIA flies in Canada with Perimeter Aviation. Two SA227-CCs are today registered with Canadian operator Bearskin Lake Air Service Ltd., while another two are operating in New Zealand. A fifth also flew with Bearskin Airlines, but
