I purchased a laser engraved knob and the thickness of the marking is very shallow. What kind of wear resistance can I expect?
The laser marking does not harm the hard durable anodize coating on the aluminum knob. The CO2 laser process only bleaches the color from the anodizing leaving a silver white color that contrasts with the surrounding dyed anodize. The durability of the laser marked area is not affected by the laser. Our tests have shown that the laser process actually improves the corrosion resistance of the anodize layer. The CO2 laser engraves aluminum knobs by vaporizing the surface leaving a deep durable groove. This groove is then filled with a special paint for contrast. The result is a durable long lasting mark.
Why is my new engine control too long/short?
What is the minimum bend radius for my engine control?
McFarlane's Storage and Packaging Specification requires a specific packaging minimum radius based on the length of the control, type of wire used, and the configuration of the control end(s). Please contact us to determine the exact requirements for your specific control.
How do I trim my engine control to length?
My Vernier-Assist Mixture control came apart during installation or maintenance. Can it be put back together?
Yes, please return the control to McFarlane for repair.
How do I clean and sanitize a McFarlane Push-Pull Control?
We make the following cleaning and sanitizing recommendations to be completed between flights:
Recommended Cleaning Process
1. Put on clean disposable gloves prior to cleaning and disinfection.
2. Pull controls back to the fully retracted position to expose the full length of the control shafts.
3. Apply isopropyl alcohol to a clean microfiber towel. Do not spray any solution directly on the controls or any other surfaces or components in the aircraft.
!!! WARNING: DO NOT USE BLEACH WIPES ON ANY MCFARLANE CONTROL !!!
4. Gently and thoroughly wipe down every control knob surface and control shaft.
5. Let cleaning solution dry on these surfaces (contact time).
6. Use a clean and dry microfiber cloth to wipe away any solution residue left on knob and control shaft surface.
7. Remove all gloves, towels, and cleaning supplies from the work area in the aircraft.
Please contact McFarlane Sales directly at 866-920-2741 or 785-594-2741 or [email protected] if you have any additional questions regarding the disinfection of our controls.
How do I keep contaminants out of my fuel system?
The fuel selector valve works in unscreened fuel. Contaminated fuel can cause selector valve seal damage. When fueling from possibly contaminated fuel sources McFarlane recommends the use of a fuel filter, such as Mr. Funnel or another filtering device, to reduce trash in the fuel system.
What pressure is used to test the fuel selector valves after repairs?
We pressure test our repaired valves to a minimum of 5 psi using precision controlled air pressure and a calibrated low pressure indicator. This pressure is above the normal fuel pressure on the valve and below the limits of the springs in the valve. Each valve is submerged in Stoddard solvent while the air pressure is applied to the valve. The valves are then tested in each position to assure that there are no inter-port or external leaks. Leaks are detected by looking for air bubbles escaping from the valve.
How do I know when to replace or service my fuel selector valve?
The most common indication of external fuel valve leaks is the smell of avgas in the cabin. Most valves are located under the cabin floor. Fuel stain on the valve and drain plug or drain valve or on the belly of the aircraft can also indicate external leakage. External leaks are generally around the actuation valve stem. Internal leaks are detected when the fuel is turned off and fuel continues to drip during fuel system maintenance. Inner port leakage will allow fuel from one tank to leak into another fuel tank. This type leak is difficult to detect. Fuel transfer from one tank to another with the fuel valve selected to one tank only will indicate inner-port leakage. An extended period of time is needed to detect fuel transfer from one tank to another. Generally if internal leakage is detected when servicing the fuel system, it is likely there is also inner-port leakage.
