In the past I have used statements like "workmanship was found to meet or exceed standard aircraft practices".
My experience aligns with Mel's statement.
People in the FAA that know their stuff, will not tolerate any logbook entry or other official statement that associates airworthy with any aircraft that has an experimental airworthiness certificate. That is why the E-AB operating limitations specifically spell out that the log entry wording be "in a condition for safe operation."
Thanks - this can be a possible letter for other TCs to leave behind on their first visit to a project -

Technical Counselor Visit
The FAA recommends that all builders use experienced builders/A&Ps and/or EAA Technical Counselors for in-process inspections of you homebuilts. Details can be found in Section 8 of the Advisory Circular AC 20-27E ?Certification and Operation of Amateur-Built Aircraft?.
These visits are to be reported both in the aircraft logbook and on the Visit Report Form, which is completed by the Technical Counselor, signed by the builder, and sent to the EAA by the Technical Counselor.
You, the builder, should make an entry in your aircraft log book similar to the following:
?I, Joe E. Builder, had EAA Technical Counselor #xxx, John Q. Smith, visit my project on <date> and workmanship was found to meet or exceed standard aircraft practices, signed Joe E. Builder.?
Visits are recommended prior to closing up major structures, and prior to covering any structure. For composite aircraft, visits are recommended when the aircraft structure is finished, but before any filling or painting is done. Each fabric covered structures should be inspected before covering.
For you RV builders, most areas are still inspectable after skinning but before adding fiberglass tips, etc., so several visits can be combined into one.
