I said that for someone to offer flight instruction, they need to be a flight instructor. If what I said is not true, then how about a reference saying that flight instruction can be offered from someone who isn't a flight instructor?
If a private pilot wants to, they can sit in the right seat of a 172 and have their best friend who is not a pilot sit in the left seat. That private pilot could teach the person in the right seat everything they know and the FAA does not care. Now if the student wants to log that training, then a CFI certificate is required.
