New Pilot: Brady Eidson
Mar 07 2011Congratulations to Brady Eidson who aced his Private Pilot checkride with Examiner Sherry Diamond. Well done Brady, and his CFI Grainne.
For his first flight as a fully fledged Private Pilot Brady took up his fiancée Betty. Good news, she was smiling a big smile afterwards.

Citabria 9091L Restoration Part 3
Mar 06 2011Did you know that a hair dryer and an iron are essential tools for building an airplane? Yes indeed! The hairdryer is used to tighten the fabric once it is put on the frame, and the iron is used to iron out little wrinkles in tight places or round corners.
Iron and "Hair Dryer"
The method of covering has not changed much since the Wright brothers and John Montgomery. The material has changed from cotton or linen to synthetics that do not get mildew or get eaten by insects or mice, and instead of leaving the fabric “naked” it is covered with protective coats of dope. The fabric (trade name Ceconite) is 100% polyester, and woven so as to prevent any rips or tears propagating (ripstop). If you come to the hangar and ask to see it we’ll show it to you and have you try to tear it. It comes in large rolls about four feet wide and is cut and shaped and glued to the frame.

In the case of wings the fabric is also riveted to the ribs. Lift over the wing will lift off the fabric if it is not properly attached. Glue alone is not enough. Once the fabric is on and heat shrunk, protective tapes are added in stressful places and over joins, then the doping starts. Nitrate dope is brushed on by hand for the first coat or two. It penetrates the weave and sets up a good substrate for the later butyrate coats. It looks greenish when dry.

Once the nitrate is done, the work can be left to wait. However if the fabric is left to wait before any nitrate is applied, dust will get into the weave and make it very hard to achieve a good coat later. So it is essential to complete the nitrate dope covering as soon as the new fabric is put on the plane.

Come and fly the Savage!
Ok everyone, Zlin Savage Classic 800NA is back on line. Come and fly her. She will challenge you and make you think you have forgotten how to use your feet. Once mastered, she will takeoff and land in less than 300′.
Check it out landing at the Santa Clara County Model Airplane Airpark ( ignore the joker with the radio control and no, do not try this without prior authorization!)
Have fun and be safe!
New Pilot: Kathleen Morse

Congratulations to Kathleen Morse who added her Airplane Single Engine Land rating to her Glider Private Pilot license, in Citabria 5032G with Examiner Sherry Diamond.
Well done Kathleen, and instructors Grainne Gilvarry and Jim Grant.
News: Citabria 9091L Restoration Part 2
Feb 25 2011Taking a plane apart goes quickly! The real time will be spent putting it all together. After stripping the fabric from the airframe, the framework turned up to be in surprisingly good condition. Even the fabric was ok, but the old paint job made it look bad. When too much dope is layered on to the fabric, it does not make things better, it tends to peel off in large pieces and makes the plane look like it is about to fall apart. However, stripping dope off fabric is generally not a good plan. It is less time consuming to get new fabric and start from scratch.

- Exterior stripped bare, interior next

- Just the landing gear to remove
While the plane is under restauration, we are also planning some upgrades.
The old wings were designed for 14 gallon tanks only and we cannot upgrade them, so Al is building us a new set of wings that will have 18 gallon tanks and modern fuel gauges in each wing root. Each wing will have two new hand built sitka spruce spars, and among other things, around a thousand rivets!
The pilot seat was not adjustable, so we sprung for a new seat frame that is, so shorter pilots can bring it closer and longer legged ones can move it further away from the panel. It should also make getting in and out a little easier.
We are still deciding on a paint scheme. I like the idea of a San Jose Sharks theme. I wonder if the FAA will let us install a shark fin? Ideas welcome.

N9091L in her better days
As most of you will know, we took 9091L down in November for a complete restauration. Over time, the sun does have an effect on the fabric, and every ten to fifteen years a fabric covered airplane will need recovering. Here’s a picture of her while she still looked pretty:
To start the process, the engine, wings, and the tailfeathers will be removed off the plane.
Engine is coming off!
The fabric covering will then be stripped off. The interior, the engine and even the landing gear will all be removed. All the metalwork will be carefully inspected, and repairs made, or pieces replaced as needed. Special attention will be paid to areas where stress is concentrated – landing gear attachment points, base of the tail, and so on.
News: Welcome to another two pilots from Spain!
Feb 19 2011I’d like to extend a warm AeroDynamic welcome to Jose Catalan Soriano and Daniel Tari Fernandez, two pilots from Spain who have come to us to learn the art of tailwheel flying and then spend some time to gain additional experience.
Congratulations to both for earning their tailwheel endorsements, and checking out in a variety of taildraggers already, including the Taylorcraft L-1, Aeronca Champ and Citabria.

News: Taylorcraft L-2 is back on line
Feb 14 2011The L-2 is back on line!
Our 1945 little warbird is back. N50839 was a real military plane in 1945, serving with the US Army on the home front as a liaison and observation plane. Converted back to its civilian form, it is a great example of a plane that so many pilots learnt to fly in – the Taylorcraft “tandem trainer”.
Come fly the spirit of a bygone age – wooden prop, “Armstrong” starter, slide open the window and stick your elbow out and enjoy low and slow flying.
Itty bitty warbird
