Preventative Maintenance

Asked by: 2110 views Aircraft Systems, General Aviation

I understand that preventative maintenance is covered quite well in Part 43.  But it does not allow an owner of a Cessna 172 to change the engine oil or put air in the tires.  I've heard that is called servicing, so it is okay.  Is there an FAR reference that lists tasks that are considered servicing?

    A list of preventative maintenance items is found in Appendix A of Part 43.

    It allows removal, repair and installation of landing gear tires. I believe you could certainly add air to a tire.

    It also allows cleaning or replacing fuel and oil strainers or filter elements.
    It also allows replacing defective safety wiring (which should also cover installing safety wire).

    I wouldn’t see a problem with changing oil, unless one needed to do something like removing the prop to remove the cowling to get to the oil drain.
