Another technician and I were on a fieldtrip to work on a grounded aircraft. I removed and replaced the right pitot. One of the nut plates was stripped and I replaced it with a nut. To my understanding the nut served the same structural purpose as a nut plate.I should have verified that with Maintenance Control.
I thought the nut would have the same structural purpose as the nutplate and its use would not affect the airworthiness of the aircraft and I signed the RII [Required Inspection Item].
Two mechanics sent to an outlying airport to perform maintenance on a CRJ-700 replaced a stripped nutplate on a pitot tube mount with a simple nut and signed off the RII in error.
