Safety Alert for Operators is issued for operators of aircraft equipped with a Night Vision Imaging System (NVIS) of potential deficiencies in the configuration and condition of installed NVIS equipment .
Recent Federal Aviation Administration (FAA) assessments of NVIS-equipped aircraft have shown that the likelihood of configuration and maintenance problems increases as aircraft continue in service after NVIS modifications. This means that operators of NVIS-equipped aircraft may not be adequately meeting the inspection and maintenance requirements of NVISs.
The assessment also concluded that operators are installing light-emitting or light-reflecting equipment, which affects the NVIS compatibility of the aircraft, without ensuring that the equipment is properly evaluated.
