Pilot, will travel, but where do I store my travel items?
These days pilots fly from base to base or operator to operator. They have their travel bag with them safely tucked in the baggage compartment. BUT that is also typically the home of your GPS system. Keeping your travel bag in the baggage compartment while spraying greatly disturbs the air flow around the GPS. This can cause an overheat situation. When working your GPS, try to have your baggage compartment as empty as possible.
Overhauling your spray pump
Here is a 13-minute video on a typical spray pump overhaul for your viewing pleasure! We carry the kits in stock, let us know how we can help.
So your Spray Valve needs overhaul too
We've developed this short video on how to overhaul your spray valve.
Have a view and call us with your questions. Yes we carry all the overhaul kits and parts you may need.
Avoid Spray System Corrosion
Corrosion eats your booms, causes early wear on spray and loading valves, plugs nozzles and can cause suck back problems.
Thrush Owners, Get that hopper cleaned out!
Transland makes this sump scavenger to help you get those extra gallons out of your hopper for when you need to change products. With this scavenger installed your remaining product in the hopper becomes much less - down to 2-3 gallons!
Fits with Dromaders as well.
Securing your aircraft
These control locks can save your plane when forced to leave on a strip and not in the hangar
Swelling diaphragms? Yuck
Fungicides can be hard on these best friends of yours. Check them often. Do you have spares on hand? They come in both fharapene and viton.
Don't lose an End Cap
If your end cap blows off at least keep it with the plane by wire locking it to the assembly. Doesn't prevent the misfortune but it does allow you to get back in the air a whole lot sooner. The ulitmate would be to have another screen on hand as well.
Sometimes you have to crawl under the plane! We have seen a couple of flow control problems result from chafed cables. Your AME would have made some holes in the aircraft belly to string the flow meter and valve cabling. A grommet is installed to protect the cables. But when that grommet flys off the plane your cables become vulnerable to chafing against the fuselage causing a short.
Electric Fan Brake
The Electric Fan brake has very positive on/off braking.
Regularly grab the fan & rotate it back n’ forth. If you feel any looseness or hear clicking, you must have this repaired within hours.
We posted this in the spring (see below), so important now.
For all Pilots flying on those hotter days!
For our Radial Pilots
Notice how your Chip Plug bulb has a push to test message on it? Don't be fooled. Pushing this just makes sure your bulb is good. It does NOT test the circuit. Properly test your plug by shorting the center pin to ground with your master switch on - if the light comes on you know your chip plug is working.
And don't keep flying if the light comes on, land and check it out. Sometimes it is a false alarm but most times it is an early warning indicator that you have an issue. Save your engine and minimize repair costs.
Know thy engine! When the wind is blowing and you have caught up on your sleep, grab your flashlight and get intimate with your radial engine. "Working engines are always talking to you" says our Director of Maintenance Allan, "if you are listening and observing closely you will detect potential issues and can monitor them or get some advice before a bigger issue develops." He also reminds pilots to check over their engine before any pressure washing. "Again, a dirty engine and dirty airframe will highlight troubles."
Stop Pump Leaks for a LONG time
We have been recommending the use of the Silicone Carbide seals versus the standard Porcelain Carbon seals for spray pumps for a number of years now. We refer to these seals as the XX seal.
We recently did a pump overhaul at the customer's request, since it had been a long time in his view. No leaks he said, just wanted to do some preventative maintenance. Inside we found a silicon carbide seal (see the picture below) that still had life left, it was in excellent shape. After some research we determined the last pump overhaul to be about 10 years ago which tallied to about 1,800 hours in service.
Here is a picture of the removed seal.
These seals are more costly than the standard seal but leaks and overhauls can be more costly.
Call Allan to discuss this further if you like.
Seals are in stock for both Transland and Agrinautic pumps.
Lane Brake Flyers
Before you start the season, we recommend pilots/operators check for free play between the Lane brake hub and the shaft of their pump. The ideal is NO free play - a small detectable amount may keep you going. However, significant free play means you should change / replace your key way before it breaks and puts you down.
This is particularly recommended for those who use the Lane brake to stop their pump (versus the conventional manual valve open/close function).
Non-Certificated operators (Flying Farmer)
In February 2016 Transport Canada released this Advisory Circular (AC 600-007) to provide information and guidance to industry, describing the acceptable means for Flying Farmers to demonstrate compliance with the regulations and standards.

Combatting fatigue in ag aviation
After 15 hours of continuous wakefulness, many people function at approximately the same level as those who are legally drunk!
These facts and more importantly, some great tips on managing fatigue can be found in this quick read thanks to our friends at the Natonal Agricultural Aviation Association.
Here is a great video on the use of pesticides in Organics
Important point: we couldn't feed the world if we didn't use some form of pesticide. And one could also add that food prices would be sky high and only the rich could afford to eat under pesticide free production models.

Suckback and correct plumbing
We've put this 3 pager together as so many people have questions. But please still call us with your questions.
Dr, Dennis Gardisser's Rules of Thumbs
Over the years, Yorkton Aircraft has attended many of Dr. Gardisser's spray pattern presentations. We noticed he uses a number of "rules of thumb" as reference and quick memory facts for proper spray application. We developed this paper with permission from Dr. Gardisser. Take a moment to read it, download it even. You will find it informative.
Components of a sound maintenance program
Obviously an aircraft that is well maintained will do its part in ensuring the pilot is safe.
But the consequences of a pilot having to deal with a poorly maintained aircraft and/or a weak maintenance program can be costly to the operation as well.
Knowing how to fly the aircraft is not enough.
Make sure the pilot completely understands how the aircraft operates including all of its systems - do they know what to look for, listen for, and feel for to ensure everything is operating properly and to detect problems. "Airplanes talk to the pilot and the maintenance crew all the time" says our Director of Maintenance Allan, "you just need to learn their language!"
Include maintenance training as part of the annual re-currency training and competency checks.
Adopt Only Excellent Maintenance Practices
Maintaining your aircraft by only the minimum required standards will give you only minimum efficiency and low return.
Maximize efficiency and return on your investment by maximizing the longevity of your engine and accessories - longevity can only be realized with excellent maintenance practices.
Make certain everyone knows the maintenance standards and schedules and maintains proper records to ensure schedules are met.
Develop Strong Liaisons - Plan for the Unplanned
Particularly with your AMO and its AMEs - develop a strong winter maintenance program and arrange dependable in-season support.
Give your pilots authority to contact the AMO with their questions and observations so they can make the correct operating decisions.
Do you have key parts on the shelf or know where you can get parts to minimize downtime.
A sound maintenance program will pay you back in:
