Why does damage to the sides of the flap tracks occur?

There are two reasons. First, the OEM Teflon washers provide great low friction characteristics, however the material is not very robust and is prone to herniating and dislodging under load

Why is the OEM roller installation complicated?

The OEM design uses many elements including a needle roller, a separate thrust washer, and a separate Teflon washer. Furthermore, there are two separate thrust washers, a steel one and a phenolic one.

Will one Landing Gear Door Hinge Kit do the entire aircraft (both RH/LH main gears)?

Yes, one kit will do both the left and right main landing gear doors.

Any tips to help me search for what I'm looking for?

If multi-word phrases do not produce results, then try searching for each word individually. The search feature is not case sensitive. All or part of the part number may be entered.

Help me use your eligibility search feature.

Here are some eligibility search tips:

• If you do not know your serial number, you can just select your aircraft make and model.
• The model you select must be specific: a 172 is not the same as a 172B.
• Serial numbers must be complete: for example, 15073660 cannot be entered as 73660.
• Hyphens in serial numbers are optional: for example, 28-7325001 and 287325001 are considered equivalent.
• For web browsers with JavaScript enabled, you do not need to click the Submit button when you select a make or model. After typing a serial number, you do need to click the submit button.
• Due to the limitations of our product database, some parts that are eligible for your aircraft may not appear on the returned list of products when your aircraft make, model, or serial number is selected. If you can't find what your looking for, please call or email us.
• Due to the possibility of error in eligibility data and the possibility of non-standard aircraft configurations, McFarlane Aviation, Inc. cannot be responsible for application of our products. The user of the products must verify correct eligibility and function of our products.

How should I inspect my exhaust system?

Refer to AC91-59A or Nicrocraft Exhaust system checklist. The American Bonanza society puts out a good video by Bob Ripley on Beechcraft exhaust inspection that is applicable to most types of aircraft.

I have an STC/upgraded engine on my airplane. What muffler fits it?

 Refer to STC Paperwork. Should specify if original muffler can fit, or a different style –possibly even for a different brand of Aircraft could be used.

What is the warranty policy?

12 month warranty, unlimited hours. Please contact our sales team for further instructions.

What paperwork comes with the muffler?

8130-3 and the warranty card.

How long is the Niel Seal Compound shelf life?

Per the supplier, there is no known shelf life.

Is this the new TiteSeal?

Yes, it is the same product. 

What dissolves Niel Seal?

Any solvent (expect water) will suffice. The vendor uses alcohol for clean up (Ethanol/Ispropyl). Acetone, toluene, mineral spirits, etc. will work as well. 

What is the difference between light and medium? How do you choose which one?

The light weight is a flexible compound for use as a joint sealing compound, caulking compound, corrosive preventative, lubricant, threaded joint dressing, insulating material, or filler with packing. 

The medium weight seals with a gasket or as a gasket. Seals pumps, tanks, pressed plates, covers, pans, etc. for pipe threads and imperfect or uneven surfaces. 

How do I know if my steering rods are working properly?

The Cessna steering system is an engineering masterpiece that is simple in function while allowing good directional control throughout the transition from flight to ground or ground to flight, even in crosswind conditions. A key part of this system is the steering rods. The steering rods are a spring loaded device that applies spring pressure to pull on one side of the nose gear when it is activated and yet have a specified amount of free play in the opposite direction until a solid push is required for positive steering.

The following are some common symptoms of worn out or failed steering rods:

1. Weak steering (You can push on the rudder but not much happens and you have to use a lot of brake to steer. Often the weakness is one direction only.) The early Cessna steering rod springs were designed such that if the rudder pedal was pushed hard in one direction while the nose gear was pointed all the way the other direction and had some resistance to moving such as soft ground or snow, the spring could be compressed to an extent that it would be permanently shortened leaving it weak. McFarlane has redesigned the spring so this cannot happen.
2. More or less than 1.2 inches of free play movement or inconsistent free play of the steering rod shaft is present. The spring is retained by a washer that was stop swaged into the steering rod housing. During an overload, such as extra hard pedal force applied with the nose wheel pointed all the way in the opposite direction and restricted or undetected damage from a previous hard landing, the spring retaining washer can be deformed and forced past the swaged stop. This will result in inconsistent free play and erratic function of the steering rod shaft as the washer passes past its designed swaged stop in both directions. The rudder rigging in flight might also be inconsistent. This is a dangerous situation that results in inconsistent steering and the steering rod must be replaced. McFarlane has redesigned the washer and shaft machining to prevent the washer stop failure.
3. Rust and corrosion can make the steering rods unreliable. The steering rods get water and contaminates from the runway that the nose tire throws at them. The fit of the shaft into the bushing that is swaged into the housing is not a precision fit. This can allow internal contamination, moisture, and salt that will rust the springs and steel housing interior, leaving the components weak and subject to failure. Red rust streaking on the shaft exit area or bubbling of the exterior paint indicate corrosion failure. The McFarlane steering rods are made from 304 stainless steel and have a special corrosion preventative and lubricating coating on the springs to fight against corrosion and wear.
4. Wear of the shaft and bushing is caused by steering movement and aerodynamic pulse vibrations created by the rotating propeller. This wear can be detected as looseness of the shaft in the end bushing. Some wear is acceptable.

The free play movement of my new steering rod has a little drag when I push it in and out. My old steering rod does not have much shaft drag. Is there something wrong with my new steering rod?

No. A little drag is expected and normal on a new McFarlane steering rod. The drag is caused by the thickness of the dry lubricant painted on the spring rubbing on the shaft. The drag is actually a good thing as it prevents vibration wear and will go away as the dry lubricant is worn in. The drag is acceptable when the weight of the spring and housing overcome the drag when the steering rod is held vertical by the threaded shaft.

What else can cause poor steering response besides the steering rods?

We have seen torn brackets on the rudder bar torque tube cause lose of rudder motion and steering movement. The earlier Cessna airplanes had less reinforcing of the rudder bar torque tubes where the steering rod attachment brackets are welded on than the later model airplanes. An overload of rudder pedal pressure or prior nose gear damage can cause failure of the bracket attachment. Inspect all of the rudder and steering system when poor steering authority is detected.

Why are my wheel pant mounting plates cracked?

Wheel pant mounting plates commonly crack around the axle. If any cracks are present, they should be replaced. The cracks are caused by wheel pant vibration. Assure that the wheel pant axle bolts are tight. Proper wheel balance will lessen wheel pant vibration. McFarlane's wheel balancers can help solve this problem.
