TOOLS
If you like tools, you’ve come to the right place! We do, too!
Below are some of our custom-made tools that we made specifically for use on the Cirrus, and then there are some general tools too that we find very useful as we maintain the fleet. We know all of these tools work and they are of good quality. If you’re looking to buy some tools, you can be confident in purchasing any of these knowing that these are the tools that we use in our shop every day to get the job done!
Custom Cirrus-Specific Tools
Fuel Injector Socket
Custom-made fuel injector sockets designed for replacing TCM fuel nozzles on your Continental-powered Cirrus SR20 (360 Series) or Cirrus SR22 (550 Series). Made of S7 tool steel, counter-bored, and heat treated. Will handle your brass fuel nozzles with ease without removing induction tubes. Use 1/2″ socket (AR1002-201) for IO360 nozzles and 7/16″ socket (AR1002-102) for IO550 nozzles. (Use a 1/2″ 6-pt 1/4″ drive swivel socket to turn this fuel injector socket.)
Custom Oil Filter Socket
Designed for DIYers and mechanics alike — our custom-beveled socket makes removing and installing your oil filter a breeze! The 12-point 1″ opening fits directly on the oil filter. The socket is specifically made to clear the Enviro and Keith air conditioner brackets. Pair it with an 11″ 3/8″-drive wobble extension (also sold in our webstore). Voila!

Gascolator Drain Valve Tool
This tool was made specifically to safely and securely hold the Curtis drain valve while removing the retaining nut. Using a 3/4″ drive wrench or socket, the two field-replaceable pins secure the drain valve against rotation. Counter-bored to fit old and new style Curtis drain valves, the tool sites flush with the surface to prevent rocking. No more channel locks or vise grips needed to do the job!
Short-Flex Turbo Spark Plug Socket
The Short Flex Turbo Spark Plug Socket has been custom-made for removing spark plugs hidden behind the intercooler on the Cirrus SR22 (turbo and turbo normalized). Utilizing a Snap-On socket and 1/2″ S7 tool steel, the components are waterjet-cut, the edges are deburred, and everything is hand polished!
90-Degree Adapter
Based on years of working on Cirrus engines, we’ve developed this tool to assist with the removal of Turbo or Turbo Normalized spark plugs. This tool extends the length of your 7/8″ 12-point flare nut adapter wrench to make removal easier. Saves time and frustration!
Tow Bar Lug Adapter
Removing a wheel pant involves spreading the wheel pant to clear the tow bar lugs. An easier way is to first remove the front tow bar lugs themselves. But don’t use a vise grip or improperly sized screwdriver!
Use our custom-designed tow bar lug adapter to make removal and reinstallation quick and easy!
Each adapter is machined from S7 tool steel and heat-treated for long service life. Designed with a ½” hex drive, the adapter can be used with a socket or wrench.
There are two lug designs used on the Cirrus aircraft. Check the chart below before ordering. *Please note that the below chart is referring to OEM lugs. If your lug has been replaced recently, you may actually have a rounded lug, as all new lugs are of the rounded style. After visually checking your plane, select the adapter that fits your lug style.

Fine Wire Spark Plug Gap Tool
Fine-wire spark plug gap tool. Designed exclusively for adjusting fine-wire electrode spark plug gaps. Two slot sizes fit all platinum or iridium ground electrodes for quick, safe adjustment.
Digital Protractor
The PRO360 digital protractor is a revolutionary measuring tool that provides an immediate, digital reading of all angles in a 360o circle. The machined aluminum frame is a rigid, light-weight, ultra-precise platform that allows the patented liquid-filled sensor and its microprocessor circuitry to provide unsurpassed accuracy throughout the protractor’s 360o range. As the protractor is moved, the liquid seeks a new position, resulting in changes in the electrical properties of the sensor. A microprocessor analyzes the changes and calculates the numbers seen on the display. Maximum accuracy of +/- 0.1o and maximum resolution of 0.1o. The easy-to-read LCD display intelligently flips over when the unit is upside down. The unit operates for up to 500 hours on a single 9-volt battery and can be recalibrated to factory accuracy in the field without special tools or fixtures. Comes with a rigid plastic case. 11.5 ounces
Magneto Synchronizer
Precision instrument designed specifically for aircraft magneto synchronization and engine timing. Eliminates all guesswork and provides a greater safety factor by creating perfect timing quickly and reliably. Features dual channels (left and right) (no audible tone). Uses electronic inductance to accurately signal when points break. Simply attach three clips to the magneto and adjust until the illuminated LED is extinguished. 9-volt battery included. 2 lbs.
6″ Safety Wire Twister
