14. Replacing safety belts. You are allowed to replace your seat belts and shoulder harnesses with approved belts for
your make and model airplane.
If you elect to change the belts it is strongly suggested that you follow the service manual instructions for installation. If the
manual calls for two washers and a spacer, use them. Changing the belts is definitely a safety-of-flight issue, which may
affect your well being.
15. Replacing seats or seat parts with replacement parts approved for the aircraft, not involving disassembly of any
primary structure or operating system.
Once again, this should be regarded as a safety-of-flight issue that can affect your well-being. The seats are specifically
designed. Don’t modify them to make them stronger or more rigid.
Replacement seats or seat parts must be of an approved design for your make and model airplane.
16. Trouble shooting and repairing broken circuits in landing light wiring circuits.
This doesn’t include position and panel lights or similar lighting systems on your airplane. If you elect to venture into other
systems, words of caution: Lack of knowledge of the system may cost you more money for needed repairs.
17. Replacing bulbs, reflectors, and lenses of position and landing lights.
Replacement is allowed in these two systems as well as in the anticollision lighting system.
18. Replacing wheels and skis where no weight and balance computation is involved.
Enough said.
19. Replacing any cowling not requiring removal of the propeller or disconnection of flight controls. Pilots are
permitted to remove and replace cowlings and cowl flaps on the aircraft they own or operate. However, don’t forget
that only certified mechanics may remove a propeller.
20. Replacing or cleaning spark plugs and setting of spark plug gap clearance.
Some important items to consider when changing spark plugs:
Have available and use the proper manuals, tools, and equipment needed for the job, which includes a torque wrench.
Use the proper spark plugs for the engine.
Know the plug rotation sequence for the engine. Many people use a simple process of rotating the plugs from top to bottom
and then next in firing order.
21. Replacing any hose connection except hydraulic connections.
Owners are allowed to replace any hose or hose connection except hydraulic connections, which also includes broken lines.
You are also allowed to change such lines as:
•
Cabin air hoses;
•
Carburetor heat hoses;
•
Drain hoses;
•
Cooling air hoses for radios.
Owners may replace static pressure lines except when used for IFR flight (see FAR 91.411); however, it is strongly
suggested that you leave those to the A&P mechanic.
22. Replacing prefabricated fuel lines.
You are allowed to replace prefabricated fuel lines with approved prefabricated fuel lines for your make and model
airplane.
23. Cleaning or replacing fuel and oil strainers or filter elements.
Follow the service manual instructions when cleaning or replacing fuel, oil, induction air, and vacuum filter elements. Use
only approved strainers and filters when replacing them. The one from the automobile parts store is not approved.
There are several ADs that come to mind when talking about filter changes. You should also check with your mechanic for
all ADs that apply to your airplane.
AD 84-26-02 requires replacement of the paper induction filter prior to reaching 500 hours time in service. You are allowed
to change the filter, but only an A&P can sign off the AD and return the airplane to service.
See the appendix for the AD.
Another AD that comes to mind is Avco Lycoming AD 80-04-03 R2, which requires at the next engine oil change, not to
exceed 50 hours, adding an additive to the engine oil, examination of the engine oil suction screen for presence of metal
particles, and the inspection of the external full- flow oil filter for metal particles by cutting it open so that the pleated
element can be unfolded and examined. You can change the oil and make your entry in the logbook, but once again, only an
A&P mechanic can return the airplane to service by signing off the AD.
See the appendix for the AD.
