Certification at 35,700 1b weight was obtained on October 29, 1957. Three versions are offered by the U.S. manufacturer: a local serviceairliner with up to 44 seats, an executive aircraft with provision for 1,380 Imp. gal fuel, and a cargo aircraft (the F-27B) with a strengthenedfloor and a larger forward door. Most of Fail-child's airline customers— which now total 12—have specified the higher-powered Rolls-RoyceDarts, but both RDa.6 and RDa.7 versions are on offer. U.S.-built air- craft include some American equipment and provision is made for noseradar.

F.27 Friendship Conceived early in 1951 as a faster, greater-capacityfeederliner replacement for the Douglas DC-3, the Friendship met with a ready response and has so far been the most successful of the com-peting aircraft in this category. An early order for two was placed by K.L.M. (delivery: April andMay, 1960). The first of four prototypes—it was 36in shorter than the second and all subsequent aircraft—flew initially on November 24, 1955.First flight of the first production aircraft was made in March 1958 and this was delivered to Aer Lingus on November 19, 1958, who became thefirst operator of Fokker-built Friendships when they inaugurated services between Dublin and Liverpool /Glasgow on December 15, 1958.Services to Paris began two days later. In September approval was given for an increase in maximum take-off weight from 35,700 1b to 37,500 lb and in maximum landing weight from 34,000 lb to 35,700 lb. A freighter with large loading doors—theFreightship—can also be supplied, and ten have been ordered. Full order book : see Flight, November 13, adding N.Z. National Airways (4). It is reported that I.A.C. may buy five Friendships until their turboprop plans are firm. The basic price of the Friendship is £218,000 less radio. References in Flight: July 25, 1958; April 3, 1959.

Grumman Amphibians The Grumman G-21 Goose six-seater airlineand executive amphibian first flew in June, 1937, powered by two 450 h.p. Pratt & Whitney R-985 Wasp Juniors, and a total of 345 werebuilt, many for the U.S.A.A.F., U.S. Navy and Coast Guard. There are 39 still in service with 12 operators, mostly in Alaska, Canada and theCaribbean. The Goose was followed by the smaller, five-seater G-44 Widgeon (first flown in July, 1940, and powered by two 200 h.p. Ranger6-440-C5 engines. About half a dozen of the 286 Widgeons built remain in airline service. The G-73 Mallard, first flown in 1946, is rather largerthan the Goose or Widgeon; it seats up to 10 passengers and is powered by two 600 b.h.p. Pratt & Whitney R-1340-S3H-1 Wasps. Only two ofthe 61 Mallards built are in airline service, with Pacific Western Airlines. The SA-16A-GR Albatross, although very similar externally to theMallard, is much larger, having over twice the gross weight and engine power and a 13ft 4in greater wing span. Albatross production (over 300have been built) has been entirely for military use, but three ex-U.S.A.F. SA-16As are used by Transocean Airlines.The following figures apply to the G-21 Goose: Powerplants: Two 450 b.h.p. (max. take-off) Pratt & Whitney R-985Wasp Juniors. Dimensions: Span, 49ft; length, 38ft 4in; height, 15ft; wing area, 375 sq ft. Weights: Loaded, 8,000 1b; disposable load, 2,575 lb; empty, 5,425 lb. Performance: Cruising speed, 191 m.p.h. at 5,000ft; max. range, 640miles.

The prototype made its firstflight on August 14, 1958, and the company has now received orders for some 40 aircraft. Up to 12 passengers can be accommodated, or 19in a high-density layout. Current basic price is about $lm. Flight reference : April 3, 1959. Powerplant: Two Rolls-Royce RDa.7/2 Dart 529 turboprops of 2,105e.h.p. each driving lift 6in diameter Rotol four-bladed propellers.

Described in Flight, July 19, 1957, page 93, it is believed that the project has been shelved. The company has since beenstudying other civil transport designs, including:— H.F.B.314 This is an 80-seat short-range jet project, presumably in Handley Page Dart Herald for B.E.A.
