Gawd...this is why people hate the FAA. Talking about an inspector with too much time on their hands. I've got a really nice 152 and yet some of those same fairings have cracks.
Don't ever let a fed inside your airplane if you can help it. Sometimes they just wander around the ramp looking for trouble. If this was a live, in person, ramp check...then I'd say you don't have much choice.
I didn't think you needed a POH...maybe that's just for older planes but I thought the placards were all that was required for part 91.
Landing light not required for day VFR....I guess to be legal you would need to placard it inop.
I'd take the plane back to the last IA and hope that he'll help you correct these things in an efficient and cost effective manner....after all, most IA's worry more about important things like cracks in a spar or engine condition than about how well you can read the compass correction card. I'd say he let some things go that this inspector flagged.
I wouldn't freak out about this...those fairings are kind of expensive for what they are but, all in all, it shouldn't be too costly to get your plane flying again.
