HELICOPTER INSPECTIONS

Please be advised that the Vista 1 Corp. will be performing Comprehensive Visual Inspections (CVI's) on the 138kV transmission lines in the CEI Region starting as soon as possible.   The CVI patrols on these lines are expected to take 4 to 5 weeks for completion and are therefore expected to be completed by January 1st 2016, weather permitting.  

The CVI patrols are a slow-speed, close-up, detailed inspection of the lines and hardware. The helicopter will be flying slowly (approximately 10 mph) along the lines and will often hover and/or circle for a close inspection of the facilities, particularly at the individual structure locations.
 

It should be noted that the contractor has been authorized to patrol the transmission circuits in their entirety (i.e. "breaker-to-breaker"), so patrols on certain lines may therefore extend into the neighboring regions. The flight crew provides information on their daily location to both Transmission Lines Maintenance and the FCC, and the pilot will be in communication with any local airports when in their airspace.  The helicopter scheduled for these patrols is a black and green, MD 500 with registration (tail) number N4QX - See below
