SIXTEEN EVENING TIMES, CUMBERLAND, MD., THURSDAY, FEBRUARY 28, 1952 Phone 4600 for a WANT AD Taker Aviation's Paradox: 4 Dry Ice, Ultra-Violet Light And Nail Polish Are Weapons As Airlines Work On Engine Maintenance EDITOR'?/ NOTE: Z»ch tueceedtng »Ir trigedy leave* aviation baifled. "It juit doMn't make tense," «avj a veteran pilot, who knows the pams taken on the (round and aloft to make air travel ai Jafe a> poa»lble. NBA Staff Writer Wade Jones wa« already at work, before the latest crash, on an exhauitlve report on what the alrlinei and government agencies are doing to cut the toll of air disasters. Here's the laft of four dispatches on aviation's paradox. By WADE JONES NBA Staff Correspondent MIAMI—It's a little surprising a first to see the burly aircraft me enanlcg daintily manipulating hot' ties of apple-red nail polish. But then, to the tot-time visitor «t the giant overhaul base of Pan American World Airways here «Verythlng Is a little surprising. About the nail polish. The mechanics are not, as you finally note with relief, putting the polish on their nails. They are daubing It on the electrical, gasoline, and oil line connections of newly overhaulec airplane engines. The idea Is that If a connection works loose in the future the bright daub of polish will break, which is a trouble sign plainly visible to any mechanic from here to Helsinki. * • * That one little trick is but a drop In an ocean of know-how applied dally here to the maintenance of the mighty engines which power our modern airliners—a phase of the total aircraft operation which as much as any other thing means safety in the ah- for you and me. Here, In Pan Am's BOO-foot-long Building 121, the world's biggest airplane engine overhaul shop under one roof, air safety is not a couple of words read In an editorial, heard on the radio, or spelled out in a CAB ruling. Air safety here is a thing you can touch with your own hands, see with your own eyes, smell with your own nose. In that space over there on the Bide, with the rubberized curtains •round it, 51-year-old Charles Russell holds forth with an ultra-violet light as inspector of all aluminum parts off the torn-down engines. * * * Working in darkness, behind dark goggles and a rubber apron, he looks for cracks and flaws in the parts, which have previously been dipped In a special chemical dye. The dye Works into the metal, and under the ultra-violet a crack ahows up as a vivid yellow streak often Invisible to the naked eye. If the flawed part can be re-machined to perfect condition, it is routed to Netv Panel-Front CRADLE FOR AN ENGINE helps remove the 3500 -horsepower, 7800-pound engine of a giant clipper plane at Miami, Fla., overhaul base.' Maintena nee of these engines is vital to safe airline operation. the proper station for the work. If not, it is thrown out. All steel engine parts go through a similar testing with a magnetic device.. At a long, high workbench three men in the almost standard uni- 'orm of white T-shirts and multihued sport caps are freezing valve seats and guides in dry ice to a .emperature of 20 below zero. * + * At the same time they are heat- ng the cylinder into which the valve seats will fit to a temperature of 400 degrees Fahrenheit. The ice- contracted valve seats will thus slip easily into the heat-expanded cylinder. And later when the two reach the same temperature they'll fit to- other like—well, like a valve in a cylinder. All Pan American airplane en- ;ines are completely overhauled after 800 to 1100 hours of use, de- jending on the type. The giant 1-4360 engine, four of which power he Boeing Stratocruiser, costs 113,600 to overhaul. Which is no surprising when you consider its 500 horsepower, 28 cylinders, seven mpgnetoes, and 56 sparkplugs. Each engine, traveling one of the bur 900-foot assembly lines in Building 121, is completely disassembled down to the last ,bolt cleaned, Inspected, unusable parts replaced or remachined, reassembled, and thoroughly tested in special cell. The complicated equipment, alone •equlred for the engine job is worth $2,500,000. * « * The entire aircraft gets a com- jlete overhaul every 8,000 hours o: ts operation. Besides engines this overhaul takes in wings, _ contro urfaces landing gear, instruments— verything. Each is sent to a par- icular shop specializing in its maintenance. Pete Parham, sprightly 58-year- ild foreman of the accessory overhaul shop, who flew the "Hump" 33 imes while on loan as a maintenance specialist to the China National Aviation Corp. during the war, pre- ides over much of this work. Pete is a great believer in the ense of touch and smell as indis- sensable aids to the complicated esting machines. "For Instance, the Vickers piston lydraulic pump works under very ligh pressure." Pete says. "When it's n the testing stand we lay a hand n it to see if we can feel any vibra- ion. If we get vibration that way, e will reject the pump whether thcr tests show anything or not.

A testing machine might have passed it as O.K." * * » As a further safety check, a complete biography is kept on every part of 'the plane that goes. through the shops showing its life v expectancy and what flaws, if any, it has developed. The Pan-Am maintenance and overhaul operation here can be considered fairly typical of the kind of care other airlines give their planes. Each believes it has the best system, but for the layman to compare them is a little too much. The work and planning and brains that go into maintenance and overhaul is impressive. Whether it is enough, only .an expert and the air accident figures can tell. Figures from the National Safety Council for 1950, the latest year for which the complete information is available, show that scheduled air transport planes had 1.1 passenger deaths per 100 million passenger miles that year, autos had 2.2, buses 0.17, and railroads 0.58. And how do the airlines of this country stack up from, a safety standpoint from those of other countries? The International Air Transport Association reports that figures based on the operations of 57 of its member airlines throughout the world, including several American, show 2.46 deaths per 100 million passenger miles in 1950. Generally speaking, this gives our airlines about a 2 to 1 per cent safety edge over those of other countries. (End of a Series) Heavy Snowfall On Eastern 'Sho SALISBURY-^) — The heaviest snowfall of the winter covered the Eastern Shore Tuesday night and yesterday with four tc- five inches of wet, clinging snow. The ground was covered from the upper shore area south to the Virginia Capes. The sun was out by midmorning, helping clear most roads of the slush. Telephone service was curtailed in several sections of the shore, but most was back in operation late in the day. About 450 phones were reported out In the Snow Hill area, 204 around 'Pocoaioke and another 80 near Berlin. The Deale Island area was without power an hour or so early yesterday after a snow-laden pine tree fell across power lines, snapping them. The State Roads Commission had 32 snow plows and 12 truck patrols working on the highways in the four Lower Maryland counties. Main roads were kept open. Worcester county- schools closed yesterday, partly because of the snow and partly because of the high rate of absenteeism caused by a mild epidemic of influenza-like j Bi< i g Qn Corriganville virus in the section. Other county 4 ° schools remained open. School Project Asked Win Margin TUSCALOOSA, Ala.—(INS)—The University of Alabama's largest margin of victory on the basketball court came in 1933 when the Crimson Tide routed a touring YMCA quintet from Dallas, Texas by 56 points, 70-14. Many householders buy commercial repellants to keep deer away from their shrubbery in areas where deer are protected closely. Sealed bids for construction of fe health room and toilet facilities at the Corriganville Elementary School will be received by the Allegany County Board of Education until 3 p. m. Tuesday, Mar^h 11. Copies of the plans and specifications for the project may be obtained from S. Russ Minter, architect, 307 South Centre Street. Electric razors are being installed in some British combat tanks. • Jonssen Pianos • Gibson Refrigerators • Gibson Electric Ranges • Detroit Jewel Gas Ranges For Cash the Cheapest t For Credit the Easiest PEOPLES FURNITURE STORE REINHARTS 17 Baltimore SI.
