OCTOBER'6, 1921 Licensed Civil Aerodromes.—The following should be added :—King's Lynn, Sayers Marsh. The following should be deleted :—Bembridge (Isle ofWight), Bembridge Farm. (No. 75 of 1921.) NOTICE TO GROUND ENGINEERS Napier " Lion " Engines : Precautions 1. Type Engines : Compression Ratio.—Both the Series I and the Series II high and low compression Napier " Lion " engines are approved as airworthy, but special precautions are required to be observed with high compression engines, in accordance with Notice to Ground Engineers No. 6 of 1921! The actual compression ratio of an engine is usually stamped on the name plate and is also noted in the Log Book. (a) High Compression.—5-8 to 1 is the standard high com- pression, and this type of engine is rated at 450 b.h.p. at normal r.p.m. (b) Low Compression.—5 to'i is the standard low compres- sion, and this type of engine is rated at 420 b.h.p. at normal r.p.m. 2. Fuel.—It is essential that the fuel used should contain at least 30 per cent, of aromatic hydro-carbons, viz. :— (a) If an Eastern or Borneo spirit is used, it is necessary that 15 per cent, of benzole be added. (6) If an American spirit is used, it is necessary that 25 per cent, of benzole be added. 3. Connecting Rods.—Three types of connecting rods havebeen fitted, viz. :—" Light " type : Assembly No. 10307. " Medium " type ; Parts Nos. 29881 (Master rod), 25639 (Cap)and 29882 (Auxiliary rod). " Heavy " type : Assembly No. 10823. Attention is drawn to the fact that cracking and breaking up of the white metalling in the big ends has occurred with the " Light " type and " Medium " type connecting rods, and it is, therefore, recommended that" such rods be replaced, within a period of running not exceeding 50 hours from last overhaul, by the latest strengthened " Heavy " type assembly. It is further recommended that oil filters be opened up, cleaned and carefully examined after each flight. Should particles of white metalling be found, the engine should be dismantled for thorough examination and overhaul, and, .f rods of the " Light " or " Medium " type are found to be fitted, they should be immediately replaced by " Heavy " type rods. Note.—Where " Light " type rods have to be replaced, new pistons and gudgeon pins will also have to be provided, owing to variation in the diameter of the gudgeon pin. (No. 10 of 1921.)
