The "REAL WORLD" is full of smoking holes, and believe me, the NTSB will come out of that smoking hole with that quick unapproved fix in their hands.
AS one of my teachers says: "we are not in the business of fixing aircraft, we are in the business of AIRWORTHINESS"
I'm not saying that the fix that you are talking about is going to effect the airworthiness of the aircraft, but the attitude of "yup,its all about keeping them going here in the
REAL WORLD!" is not quite right, especially when you don't have a mechanic rating.
Also, I think it is interesting that you deleted the post where you wrote basically that you were the aircraft cleaner and that you were doing this fixes by yourself.
