Lycoming Service Letter L180B

Written by
Engine Preservation for Active and Stored Aircraft Engines in aircraft that are flown only occasionally may not achieve normal service life because of corrosion. This occurs when moisture from the air and products of combustion combine to attack cylinder walls and bearing surfaces during periods when the aircraft is not used. The procedures for combating this condition consist of coating the vulnerable surfaces with rust inhibitive compounds as herein described. Click link below to download PDF
Aeronautical decision-making (ADM) is decision-making in a unique environment—aviation. It is a systematic approach to the mental process used by pilots to consistently determine the best course of action in response to a given set of circumstances. It is what a pilot intends to do based on the latest information he or she has. Click the link below to download PDF

Louisiana’s Other Side: Shreveport

Written by
It's more than just a mile from Texarkana, and it's more than just a relic from the steamboat days. April 2015- The surveyors were off—by a whole 30 miles—but the song is still popular. That song would be "Cotton Fields" recorded in 1940 by blues legend Lead Belly and covered by everyone from The Beach Boys, Elvis, Johnny Cash, and, of course, Creedence Clearwater Revival. Shreveport, La., a city with a metro area of over 350,000 residents, is now the economic center for a tri-state area known as "ArkLaTex." Shreveport today is revitalized in large part because of the introduction of riverboat gambling in the 1990s. With five casinos in the Shreveport-Bossier area, locals—and visitors (mainly from "Ark" and "Tex")—can find their favorite slot machines, games tables, and even a horseracing track. If a quiet day fishing by kayak is more your style, Shreveport can provide that, too. Several outdoor recreational areas, including Cypress Black Bayou in nearby Benton, provide visitors an opportunity to fish, swim, camp and explore. Bassmaster fishing tournaments are held frequently on the Red River, and this twisty-turny waterway is what geographically separates old-town Shreveport and Bossier City (pronounced "Bozhur"). The climate here is zone eight,…
Single-pilot light aircraft operations require good raining, sound procedures, excellent motor skills—and an awareness of our own cognitive bias. April 2015- Flying offers so many possibilities. As pilots we can pull our aircraft out of the hangar virtually anytime we want and sail to any horizon. It's a privilege that comes with immense responsibility. When we deploy our aircraft, we have tools to keep us safe. Combined with our training, these tools can take much of the risk out of operating aircraft. The term fail-safe is often used to describe many of our critical light aircraft components, and our Cessnas are built with intelligent systems that consider human factors and have ample safety margins. In many cases there are redundancies so if one system fails, another takes over. But what about the system between our ears? That system is responsible for thousands of tasks and decisions each and every flight. Fortunately for us, it works remarkably well. Through disciplined use of procedures, good training and excellent motor skills, we can maintain very high levels of safety. But our brains aren't without fault. Cognitive biasThere are several areas where our old dependable noggin can let us down in a big way.…
"If you're at 65 percent of power or so, 50 degrees rich of peak probably won't get you in trouble, and will give you close to maximum power for that manifold pressure and rpm. But the fact is that 50 degrees rich of peak will produce the absolute hottest possible temperatures for all parts of the engine." -John DeakinAdvanced Pilot Seminars April 2014- Prior to my first cross-country flight from Seattle (KBFI) to Arlington, Wash. (KAWO), I was told that we were going to lean the engine when we got up to cruise altitude. I was instructed to pull the mixture knob slowly aft until the engine started to get rough, then to push it back in until the engine smoothed out. Since those early days I've learned quite a bit more about leaning. The following is a general discussion on the basics of leaning; it is intended only to be educational. Always refer to your Flight Manual or POH for specific leaning instructions. Red knob basicsLeaning seems simple: since air density decreases as air temperature and altitude increases, and since the carburetors and fuel injection components on our airplane engines don't adjust for these density changes, pilots need to…
Hi Steve,I sent you a picture of a part I need for my Cessna 182 (photo, above). This part screws into the intake manifold above the carburetor. The hose for the manifold pressure gauge screws onto the part. My mechanic told me I need to change it, but I haven't been able to find the part number in my Cessna 182 parts manual. Can you help? —Brad Robinson Dear Brad,The part you're looking for is called an adapter assembly and the Cessna part number is 0750282-1. That's the part number for the item that connects the manifold pressure line to the engine according to the 1962-73 Cessna 182 parts manual. The list price for the part is over $400, although you may be able to get a used one from an airplane salvage company such as CFA supporters Wentworth, Dodson and Preferred Airparts; White Industries, Texas Air Salvage and others may also have it. KRN Aviation Services shows three on hand, according to its website. The part appears to be a standard AN flared tube-to-pipe thread aircraft part that has a short steel tube brazed on the pipe thread end. The only reason for the short length of tubing is…
Widespread fog prompts a change of heart about personal minimums on departure. April 2015- I have never been a fan of personal minimums—the idea that you should set limits for yourself short of what's required by the FAA. Particularly for instrument flying, if you aren't prepared to shoot an approach to minimums as specified on the chart, you shouldn't file, because you're going to have to deal with whatever weather develops.That's one reason for the "1-2-3" rule about specifying an alternate if the weather isn't forecast to have at least a 2,000-foot ceiling and three miles visibility for one hour before and after your planned time of arrival. But I've had a change of heart, at least in one respect: I've now set personal minimums for visibility and ceiling when departing on an IFR flight. That came about as a result of planning for a flight to Los Angeles with my wife during the fog season. We were in a relatively wet winter season here in California's Central Valley, which makes fog common. When there's no frontal weather, radiation fog is common most mornings and indeed sometimes builds up to persistent tule fog that can cover fairly large areas. Most…
