Bell 222 pilot briefly utilized Night Vision Goggles in an aircraft which was not modified and certified for NVG use.

Narrative

While flying on an inter-facility flight in a NON NVG [Night Vision Goggles] modified aircraft; I had NVGs mounted on my helmet and used them momentarily to ensure terrain clearance and to identify known obstacles on my approach paths. I did not fly an NVG profile or use them in the entirety of the flight. I used them only momentarily to ensure terrain clearance and to quickly ID obstacles on my approach path. 99% of the profile was unaided with my using standard night flying techniques such as appropriate altitudes; known land marks; and supplemental lighting (Searchlight & Night Sun). To ensure a safe flight route; I maintained the appropriate altitudes until I arrived at known landmarks that ensured terrain clearance prior to any descents and used outside visual references with a good scan without using the NVGs. I used them strictly momentarily and my intent was to enhance safety and not to flagrantly violate any regulations; instructions or directives. If I did so it was purely unintentional. I used poor judgment and should not have utilized the NVG's in an un-modified aircraft. I accept responsibility for my actions and realize I acted incorrectly. While my intentions were safety related; my actions were incorrect. I will ensure this will not occur again by not taking NVGs on board a non-NVG modified aircraft and flying unaided when conditions are appropriate and not accepting the flight if the conditions are not appropriate for unaided flight.
