Aircraft Maintenance Checklist

As an aircraft owner or a Aircraft Mechanic, you have several responsibilities to ensure a plane is airworthy before take-off. With so much to consider, it can be hard to keep track of every little maintenance issue. Cirrus Aircraft Maintenance is here to help you keep your airplane in takeoff condition all year long.

Before soaring into the sky, a certified pilot who is the owner of an aircraft (that isn’t being used as an air carrier service), or a qualified airplane mechanic should go over this list to ensure the plane is in tip-top condition and ready to fly. So, it’s time to get started – here’s the Ultimate Aircraft Maintenance Checklist – let’s go!


▢ Review the aircraft’s maintenance records and service logs.

▢ Removal, installation, and repair of landing gear tires.

▢ Inspect tire pressure and wear.

▢ Replace elastic shock absorber cords on the landing gear.

▢ Service landing gear shock struts by adding oil, air, or both.
