Next weekend, 6-7 Jan, we hve our FAA IA siminar I'll bring this up to the Continental rep, and the FAA GA supervisor.

I will ask you what you use as a list required by.

(c) Annual and 100-hour inspections.

(1) Each person performing an annual or 100-hour inspection shall use a checklist while performing the inspection. The checklist may be of the person's own design, one provided by the manufacturer of the equipment being inspected or one obtained from another source. This checklist must include the scope and detail of the items contained in Appendix D to this part and paragraph (b) of this section.


plus 43.D says

(3) Internal engine-for cylinder compression and for metal particles or foreign matter on screens and sump drain plugs. If there is weak cylinder compression, for improper internal condition and improper internal tolerances.

I think the FAA could make a pretty good case for doing a compression check, and if you are going to do the check, you are reqired to do it in the way that the manufacturer wants you to.

Just MHO
Tom, it is right there in the letter. Let them argue with her!

Do it per 43.13 1B.......
