Canberra parts produced have included frames, bulk-heads and fuselage assemblies, ribs and details for the wings, tailplane, fin and rudder and also 250-gal wingtip drop-tanks. ForJindivik fuselage and wings, details and sub-assemblies have been manufactured.The company has also undertaken the manufacture of a varied range of volume-production supplies for the Department ofDefence Production, including projectile containers, flares, markers and rocket saddles. Manager of the aircraft division is G. V.Hemer. KINGSFORD SMITH AVIATION SERVICE PTY., LTD. P.O. Box 11, Bankstoum, New South Wales. OST outstanding development in the activities of this com-pany over the past twelve months has been the completion of the prototype PL-7 Tanker agricultural aircraft. This machinewas designed and built in only sixteen months, specifically for top-dressing, crop-spraying and other agricultural purposes.Designer of the Tanker is L. Pellarini. The unorthodox layout of the PL-7, which is powered by anArmstrong Siddeley Cheetah X engine of 400 h.p., is well illus- trated in the photograph on this page. The forward section ofthe fuselage consists of a welded mild-steel tank forming a hopper and carrying all main loads. To the forward face of the tank isattached the engine-mounting frame and nose-wheel boom; the rear face carries the rear-fuselage cone containing cockpit andfuel-tank. The fabric-covered steel-tube tail unit is carried on two tubular steel booms projecting rearwards from the centre-section spar and braced to the tank unit. Simplicity in design has been the aim throughout. Wheels, tyres and shock-absorber units of the non-retractabletricycle undercarriage are interchangable throughout. Hydraulic brakes are fitted to the mainwheels and are operated by meansof toe pedals. The nosewheel is directly steered by means of cables from the rudder pedals. All control cable-runs from cockpit totail are carried externally along the booms and boom supports. Dimensions and performance data for the PL-7 include: span40ft lOin (upper) 30ft (lower); length 24ft 6in; height 12ft; wing area 405 sq ft; gross weight 5,000 lb; cruising speed (75 per centpower) 112 m.pii.; operating speed (top-dressing and spraying) 70-90 m.p.h.The company's other activities at Bankstown include the manu- facture of aircraft components, the overhaul and repair of aircraft, engines and accessories, and the supply of spare parts, aircraftmaterials and products of the Auster and Blackburn companies. The expansion of the company's interest in agricultural aircrafthas been a notable feature of its development over the past two years.Managing director and general manager is J. T. Brown.
