How to Winterize Your Plane for Cold Weather Storage and Flying

The temperature is dropping, and it’s time once again to get your plane prepped for cold weather storage and flying. Winterizing your aircraft not only ensures the safety of all those on board, it also helps to prolong the life of your plane. If possible, store your craft in a temperature-controlled hangar during the cold months. Whether or not that’s possible, here’s a checklist of some important things to do before putting up your plane for the winter.

• Reread the aircraft flight manual, particularly the sections on winterization.
• Keep the aircraft in a hangar, especially the night before a flight, if possible. If not, make sure the plane is covered.
• Make sure that the plane’s anti-icing or deicing systems are operational.
• Change the engine oil to multi-grade, or the manufacturer-approved cold-temperature oil.
• Install a winterization kit to deflect the cold air and keep the cylinders warm.
• Renew the carbon monoxide detector and have the system checked for cracks.
• Turn on the cabin heater, heated pitot and demister to make sure they work.
• Make sure pitot head covers, static vent plugs, control surface locks and tie-downs are in working order.
• Confirm drain holes are clear of dirt and debris to prevent standing water from freezing and causing blockages.
• Check the carb heat and alternate air inlet, especially before takeoff.
• Find out if your aircraft requires isopropyl alcohol in the fuel for operation in low temperatures.
• After refueling, let the fuel settle in the tanks, then check for water in the system.
• Check that all the airframe, propeller and windscreen systems are operating correctly.
• Check that inflatable boots inflate properly, especially on the tailplane.
• Check that the battery is fully charged, and the alternator is working properly.
• Clean the airframe of mud, slush and dirt to prevent buildup in wheel pantsand elevator hinges.
• On flight day, wear warm clothing and waterproof footwear.
• Pack a cold-weather parka, heavy blanket and winter survival kit on the plane.
• Before takeoff, get an up-to-date aviation weather forecast and note any icing warnings.
• Make sure your route plan is accurate and you have an alternative in case you encounter ice and snow.
