Hello
everyone, It’s getting to be a rare site to see an aircraft coming out of the
hangers or seeing a transit coming for a stopover while working on the
Chapter Building, Now it’s mostly a heavy twin coming in for a business
visit. All we can do is sit tight and weather out the storm and hope
prices come down again. A Class I event is a Chapter fly-in and there would be no additional insurance cost to the Chapter. I would like to bring it up to the membership for approval and hopefully to set up a fly-in committee. A fly-in would be fun, with a lot of options for what we can do under a Class I. We can make it a great event for us and the Festival crowd. We’ve worked very hard on our new building and given up a lot of activities to finish it. Now comes the time to make good use of what we have and start planning events for the upcoming year. We don’t have a guest speaker lined up for the September meeting but,
as always, we’ll come up with something. This meeting will be held at
the new Chapter Building. We are hoping to have all the siding on the
hanger door and we will show all our members how to open it and the access
doors.

Hanger
Update: There has been a mainstay
crew that has been at almost every work party and without their help
we never ever would have gotten as far as we have with this project.
I would like to mention their names: A special thanks goes to Dick Guenther who loaned us his scissor lift for the project and with out which the project would have been next to impossible. I would also like to thank
these members who gave a lot of time. There is still work to do,
including the sheeting on the front of the building and doors, wiring,
interior work and landscaping, but that will be done in good time.
We will need your ideas and input as to how we can make the best of
what we have.
News: It's finally here thanks to AOPA. Now with a click of your mouse, you can find out whether any special-use airspace (SUA) — restricted area, military operations area, military route, or warning area — anywhere in the country is going to be "hot." Now you'll know where the fast-movers are and whether you can take that
shortcut through the MOA or restricted area. More on special-use airspace... Hypoxia Oxygen-use requirements are
spelled out in FAR 91.211. Crew members must use supplemental oxygen
when the cabin pressure altitude is above 12,500
feet for longer than 30 minutes, and must use it continuously when flying
above 14,000 feet pressure altitude. Hypoxic can make one feel very good
making it easy to dismiss. Our brains use approximately 30 percent of
the oxygen circulated by our red blood cells and any deprivation, however
slight, insidiously chips away at our brain's ability to function competently.
When we become hypoxic we are more prone to make mistakes, misinterpret
instruments, and fail to remember basic skills. Vision is the first system
to be effected; at 10,000 feet night vision is degraded by 15 to 25 percent.
Breathing oxygen for a few minutes before an approach, or when flying
after sunset at altitudes as low as 5,000 feet, generally restores normal
vision and brain function. The decrease in blood oxygen saturation with
an increase in pressure altitude is predictable. What isn't predictable
is a pilot's ability to take in and distribute the available oxygen.
Some of us, because of a number of factors, don't do as well as the charts
say we should and become hypoxic at lower-than-predicted altitudes. Because
hemoglobin likes to bond to carbon monoxide (a product of tobacco smoke)
200 to 300 times more than it does to oxygen, smokers don't have access
to their full capacity for circulating oxygen. There are other factors
that can cause lower than normal resistance to hypoxia. Normal blood
oxygen saturation levels are 96 to 100 percent at sea level 93 to 95
percent at 5,000 feet pressure altitude, 90 to 93 percent at 7,500, 88
to 92 percent at 10,000, 83 to 87 percent at 12,500, and 77 to 83 percent
at 14,000 feet. However the effects of hypoxia are cumulative over time
and can effect some people at altitudes below ten thousand feet. If you
or a passenger get a mild headache while flying, hypoxia could be a cause.
Fly safe - Don ELT
Warning Aircraft owners and pilots should be aware that ELTs that transmit on 121.5 MHz will still satisfy FAA requirements and be legal after the transition date, but they will provide limited assistance in the event of an accident because their signals ill no longer be received by a satellite. However, the FAA and the Department of Defense will still monitor the frequency from the ground and can initiate search-and-rescue operations. Flight

FAA intends to issue Lycoming crankshaft AD The FAA says 12 crankshafts have failed in these lower-powered engines, echoing a problem of three years ago in the higher-horsepower turbo-charged Lycoming 540 engines. The AD would require replacing crankshafts made using a hammer-forged process with crankshafts manufactured using a press-forged process. Some 1,128 engines installed on U.S.-registered aircraft would need to be repaired. The affected airframes range from Aerostars to Socata Trinidads, but Lycoming told AOPA that the bulk of the affected aircraft are Robinson R-44 helicopters and late-model Cessna 182s. If your engine was manufactured before March 1, 1999 (and you haven't
had the crankshaft replaced), you don't need to worry. FLYING
