FLIGHT, JULY 24, 1931 WELL AWAY: A good picture of the giant Junkers "G.38" commercial monoplane taking off during its recent tour of Europe. South African Airways THE Senate of the Union of South Africa has given asecond reading to a Bill empowering the railways to operate air services. The Minister of Railways and Harbours, Mr.C. W. Malan, speaking in support of the Bill, foresaw that within ten years there would not be a single business manwho would not make use of an aeroplane in the course of his business journeys between Johannesburg, Durban andCapetown. Night Flying in U.S. SEVEN and a-half million miles were flown at night bymail and passenger lines in the United States last year. On the 2,700-mile coast-to-coast flight of United Air Linesbetween New York and San Francisco, pilots have the advantage of 111 lighted emergency fields in addition to themany lighted municipal and private airports. There are 16 ports of call for the night air mail-passenger transportsbetween New York and the Pacific Coast. It is claimed that the total night flying in Europe during 1930 was onlyone-third of that flown by United Air Lines. A Colombian Air Concession Modern Transport reports that the Colombian Govern-ment has consented to the sale of the " Scatda " (German system of air lines) to the Pan-American Airways, which will <$> <§> take over and largely extend the whole of their air servicesin tnc interior of Colombia. A new long-term concession has been granted, in return for which the Pan-American Air-ways undertake to inaugurate before the end of the year another air mail service between Bogota and New York,the journey not to take more than three and a-half days. It is also proposed to establish an air service betweenMedellin (the second largest town in Colombia) and the Gulf of Uraba, where important harbour works are con-templated. Meanwhile the Government has prolonged the contract with the British member of the Consejo Nacionalde Vias for a further period of six months. An Air Service in Nyasaland Ax air service is to be established in Nyasaland, andthe first aeroplane for the service left Johannesburg on July 17 for Blantyre, with Mr. Christowitz, the founder ofthe service, as passenger. The machine will be christened " Miss Nyasa " by the Governor of Nyasaland. Its chiefroute will be between Blantyre and Salisbury. A New Dutch Indies Service K.N.I.L.M., the Dutch-Indian air line, will start anew weekly service between Singapore and Medan, and vice versa, on August 6, as an extension to their presentweekly service between Batavia and Singapore. <§><•> •- AIR MINISTRY NOTICES IT will be seen from the following notice that the AirMinistry Notices to Airmen have been sub-divided in a new manner, and are to be distributed in a different way thanhitherto. In view of this distribution and of the increasing size of these notices, as well as those to Ground Engineersand to the increasing pressure on our space, we shall in future not publish these notices in full, but will summariseeach notice as it appears. We feel that by so doing we shall be enabled to keep up to date with these, as issued,and readers will, from these summaries, immediately be able to see which notices interest them particularly, and if desiredmake application for copies to the Air Ministry. NOTICES TO AIRMEN, SERIES A No. 37 of 1931. Dropping of cables used for the towing of gliders(117,151/31) A NOTIFICATION that cables used for towing gliders may be droppedat a height not exceeding 300 ft. and only over a licensed aerodrome, so that the cable falls entirely within the boundaries of the aerodrome and only ifthe written consent of the controlling authority of the aerodrome has been obtained. No. 39 of 1931. Examination for Civil Air Navigators' Licences.(110146/31) NOTIFICATION that an examination for first-class air navigators' licenceswill be held in London on October 5, 6, 7 and 8, 1931, while an examination for second-class air navigators' licences will be held on October 5, 6 and 7in Londo n, Heliopolis, and Baghdad. A further examination for second- class air navigators' licences will be held on or about the end of March, 1932. No. 40 of 1931. Reporting of Aircraft Flying on the Regular Routes.(113151/31) THE departure and arrival of aircraft operating on regular services inGreat Britain, Belgium, France, Germany, Holland, and Switzerland is reported from aerodrome to aerodrome by wireless telegraphy, and otheraircraft when flying over a regular route may similarly be reported at the request of the pilot. These should invariably report by telephone to theaerodrome of original destination or to the nearest aerodrome open to public air traffic the news of a forced landing or change of destination. No. 41 of 1931. Salt End Chemical Works, Hull : Danger Area.(64664/30) FLIGHT over the works of the Salt End Chemical Works, Hull, at analtitude of less than 1,000 ft., should be avoided. These work* are situated *i miles E. by S. of the centre of Hull and one mile S.W. by S. of HedonAerodrome. NOTICES TO GROUND ENGINEERS No. 33 of 1931. Engines: Locking Wire for Carburettor FloatMechanism. (99303/31.) As engine failures have been caused by the breakage of the locking wireIn the needle toggle pins of carburettor floats, these locking wires are to De replaced by new material after dismantling. No. 34 of 1931. Napier " Lion " Engines : Tightening of Nuts onMaster Connection Rods. (17765/30.) Attention is drawn to the special care required when tightening the nutson master connecting rods studs on " Lion " engines. The makers employ a spring-loaded spanner set to give a maximum of 945 in.-lb. (135 lb. at7-in. radijs). This is to ensure that the bearing cap is securely held with the studs under running conditions without stretching. When such a spannerIs not available, a box spanner and tommy bar can be used, the bar not exceeding 7$ in. from the centre of the spanner. In order to secure align-ment of the split-pin hole in the stud and the castellation of the nut, the bottom of the nut should be faced off (0010 in. removed from the face ofthe nut will allow it to be tightened down ~th of a turn). A special tool, part No. 48263 is to be used for such an operation. Nuts must on no accountbe slackened back, but further faced down until the next slot comes into correct position. Split pins must not be more than i in. long in the parallelportion, and be correctly opened out so that no movement of the pin can occur. Studs for the master connecting rod are made from steel to B.E.S.A..Specification S. 65. Directions are also given for removing old studs and replacing new ones, which directions must be very carefully followed. Noticeto Ground Engineers 28 of 1930 is hereby cancelled.

It has been found that the aileron controls occasionally foul the bent downbracing lugs at the inner ends of the rear spar on the underside of the lower planes. These bracing lugs are therefore to be removed, since they areredundant. The ball joint, aileron lever and connecting rod have been replaced by new parts obtainable from Spartan Aircraft, Ltd., and mustbe incorporated in all the aircraft concerned before August 9, in order that certificates of airworthiness may remain valid or may be renewed. No. 38 of 1931. A Series of Modifications to the Mk. 1 Cirrus-HermesEngines. (95422 31.) The first referred to auxliary cylinder lubrication and a jVin. diameterhole has now been drilled in the four plugs in the crank webs.
