First, buy the maintenance manuals and parts manuals for your airplane,
become very familiar with them. The more correct information that you can
give an A&P before he looks at your airplane the easier it will be for him
and the cheaper it will be for you. The internet is a great resource for
parts and supplies, but having the part numbers makes things a lot easier.

Second, network. Where do other people on the airport get their work done?
Start a list of A&Ps in your area. Search the FAA database and compile a
second list of names not found on your first list. Contact some of these
people. Join your appropriate type clubs, groups, and local EAA chapter
They are invaluable resources. An EAA chapter is a great place to meet
retired A&P's that are interested in helping you do things right.

Compile your resources. What pilots/owners have what tools and or
equipment? What are the mechanical abilities and capabilities of the other
owners on the airport?

Talk to as many A&Ps as you can. Are any of them looking for extra part
time work in the evenings or on weekends? Who will let you help? What
about retired A&P's who may let you do the grunt work then sign it off for
you?

Are there any "seasonal" operations on or near your airport that may have
mechanics with spare time in between busy seasons or busy days of the week?
Think about ag operators, freight haulers, small 135 operators looking to
fill in their down times.

Don't forget about the owner approved maintenance list. Locate the periodic
maintenance checklists in the maintenance manual for your airplane. You'll
be able to do many of the listed items yourself.

Remember that an "annual" is an inspection, a local A&P can do any required
work then an AI can pay a visit to do the inspection.
