(d) A person working under the supervision of a holder of a mechanic or repairman certificate may perform the maintenance, preventive maintenance, and alterations that his supervisor is authorized to perform, if the supervisor personally observes the work being done to the extent necessary to ensure that it is being done properly and if the supervisor is readily available, in person, for consultation. However, this paragraph does not authorize the performance of any inspection required by Part 91 or Part 125 of this chapter or any inspection performed after a major repair or alteration.[/QUOTE]

When my dad had his Piper Vagabond or Clipper in for an annual, he as an A&P would open up and un-cowl the airplane for the IA. He would also lube pulleys and wheel bearings plus other maintenance items, clean and gap plugs etc. As I'm reading the above, those are maintenance items, not something an inspector is going to do.
So I can do all those things necessary once a year, enter them in the log, then the inspector, A&P, signs off the inspection? I do have a short list of upgrades to my IV that will require a new W&B done. And I will have to fly off time with a new prop... That's another whole thread of questions.
