JANUARY 10, 1929 The usual fireproof bulkhead is inserted between the cabin and engine compartments and the engine mounting is so designed as to afford easy access to the rear of the power plant when it is necessary to adjust or repair carburettor, magneto or starter. The exhaust ring is sunk into the cowling to reduce parasitic resistance, but an air channel is provided around it to prevent overheating. Fuel supply of 40 gallons is carried in the two wing tanks over the fuselage and accessible through cover plates. An emergency tank of 10 gallons capacity feeds directly to the carburettor eliminating the necessity of a forced landing if the fuel supply from the main tanks is stopped. The landing gear is of the split-axle type, built up of heat-treated chrome molybdenum steel tubing with Gruss shock absorbers inserted in the compression members. Bendix wheels and brake units are used and the brake control is so adjusted that either or both brakes may be applied at will. A leaf steel spring is used to absorb tail skid landing shock. The landing gear, tail skid, door handles and control horns are the only members protruding beyond the outline of the 'plane, all other units being streamlined into the structure. The specifications furnished by the manufacturer are as follow :— Span Length o.a. Height Chord (maximum) Wing area (including flaps and ailerons) Flap area Aileron area Elevator and stabiliser area Rudder and fin area Power plant Fuel capacity Oil capacity Speed, maximum Cruising Landing, flaps up Landing, flaps down Rate of climb, sea level Service.ceiling 39 ft. 25 ft. 7 ft. 9 in. 8 ft. 226 sq. ft. 21J sq. ft. 19 sq. ft. 30£ sq. ft. ll|sq. ft. 150 h.p.

SMART SERVICE THE private owner will rely at times upon skilled assistance during his tours whatever machine or engine he is flying: just as the motorist with the best car on the road cannot do without garages occasionally to avoid being stranded. At this stage in private flying the owner cannot expect help by air yet as a rule, but there are exceptions, of which we here give a topical instance. Tt should be remembered bv any air tourists in the south-west of England for guidance in a similar emergency. On Christmas Eve Flight-Lieut. Scholefield, test pilot to Vickers, Ltd., crashed in an Avro " Avian " at Whit- church. The Agra Engineering Co., Ltd., of Teignmouth, Devon, who have an aerodrome at Haldon, Teignmouth, were immediately asked to salve the machine by the British Aviation Insurance Group, and save it from further damage. On Christmas morning Flying Officer W. Parkhouse, the managing director, left Haldon aerodrome in his own Avro " Avian " with Mr. Lee, one of his pupils, and flew to Whitchurch, which is 6 miles east of Andover, in 1 hr. 5 mins. Flight-Lieut. Scholefield's machine was found to have crashed into the River Test and been hauled to the bank. It was dismantled and transported to Whit- church, then Flying Officer Parkhouse flew back to Haldon in 1 hr. 45 mins., to resume his interrupted holiday in North Devon. This is an example of the prompt service given by the Agra Engineering Co., Ltd. The Avro '' Avian '' light aeroplane salved from the River Test at Whitchurch after. a crash during theChristmas holidays. It was taken charge of and dismantled at quick notice by the Agra Engineering Co., Ltd., of Teignmouth, the managing director of whom flew to the scene in another Avro " Avian " 27
