Beechcraft both in his frequent business travel necessary to his career and for personal transportation Kennedy became a pilot through his association with the Airport movies and the role he plays in them the tough cigar chewing Joe Patroni It was the real Joe Patroni the man on whom the Patroni character was based who convinced Kennedy he should learn to fly 10 years ago He has flown many hours since and currently holds a private pilot s license with instru ment and multi engine ratings The real Joe Patroni he said is a fellow named Roy Davis who is head of maintenance at TWA in Chicago He s not a big man but he chews a cigar like Patroni and he actually did what Patroni does in the first Airport movie gets a stuck airliner out of the snow I spent some time with him to get a feel for the character and one day when we were having lunch I said you know I ve always wanted Page 930 News and Views GEORGE KENNEDY continued to learn to fly Now that I can afford it I m too old He said That s no excuse I ve taught people to fly who are over 70 Kennedy took Davis license Discussing his purchase Kennedy said he chose the Beechcraft Bonanza A36 because it has an excellent repu tation it s big it s fast it has good range and it s easy to fly After his tour of the factory Kennedy added that Seeing the way Beech builds the Bonanza from the inside out and the meticulous atte

Newsletter The information is always useful and enjoyable reading I would also like to express my thanks to Norman Colvin for his encouragement when I was trying to make up my mind on the spar replacement in our 35 He was certainly right It is a worthwhile modification and I would not hesitate to do it again My wife and I own D703 a straight 35 at least it started that way It has had its fair share of modifica tions Spar M air tips new panel and many more When we bought 3256V it had a little ignition noise in the radios An Alpha 200 and a MkII made up the radio stack Locally the noise wasn t too bad but in the country it was something else The mags were overhauled the harness replaced and all the details taken care of The result was barely acceptable Later the radios were replaced with a pair of KX160 s and things were much im proved During all these happenings another strange thing would occur The prop controller would blow an occasional fuse Always during start up or at least prior to run up After replacement the control would work fine Several bench checks were made and always showed the same results nothing wrong with the controller Last year the controller got erratic and was again pulled and same as before worked great on the bench but now it was bad in the plane After a few in and out cycles I was determined to find the problem After much testing without any results I gave up the test equipment and

7. A District Office for assistance in determining the airworthiness status Recommendation It is recommended that no material be placed in the windshields or windows of an aircraft which will in any way reduce the field of vision of the safety pilot below what it would be without the presence of such material In addition sun visors aircraft curtains instrument simulation slats or other view limiting devices should be removed or placed in the retracted position when not actu ally needed and being used to limit the pilot s outside reference J A Ferrarese Acting Director Flight Standards Service ktk BRAKES AND BRAKE RESERVOIRS The tin can brake reservoir in old Bonanzas is vented in a way that can promote water ingestion The vent hole is located on the side of the threaded filler neck so that the reservoir cap partially covers the hole I suspect that the designer intended the cap to act as a roof to protect the vent hole from rain In my straight 35 this vent arrangement was causing large amounts of water to be drawn into the system The raised rim of the reservoir would allow approximately a teaspoon of rain water to puddle on the top Operating the brakes would suck water through the vent hole into the reservoir I have found that the geometry of these tin cans varies from aircraft to aircraft In most the can s top piece is conical so that the vent hole is well above the rim height and the problem does not exist A s

I was probably leaving a puddle of water in the bottoms of the cylinders There is a 10 32 screw in the cylinder cap plate that may have been intended to drain water from the system However if you are interested in saving your Goodyear brakes from corrosion I would recommend removing the C ring retained cylinder caps and wiping the cylinders clean I would not be alarmed if you find a small amount of corro sion as the 0 ring seal seems very tolerant of surface roughness and the brakes may function just fine Refill the system by upbleeding with freshly purchased hydraulic fluid This fluid is designed to absorb moisture A can that has been sitting around the hanger with the lid off is probably already saturated with water R C Keiter ABS 5686 Airborne Electronics Inc Healdsburg California kK KKK ABS GROUP INSURANCE HOW IS IT PERFORMING San Antonio another outstanding ABS meeting Weather beautiful attractive city with fine facilities excellent program and arrangements many old and new friends many questions about the program The reason for a group insurance program is to combine a sizeable group which year after year has losses lower than average This allows the company to pass along premium savings to the members The ABS loss record is excellent and getting better You know how much more all repairs cost today but there has been no increase in ABS rates for three years What can group insurance do for you if y
