Please be advised that Penn Power plans to start performing Spring Routine Patrols on the transmission lines beginning the week of March 20, 2017 weather permitting. The helicopters that will likely be used for these patrols are a black Bell Jet Ranger with tail registration N321AW, a black Robinson R44 with tail registration N7193Y, and a black and green, Hughes MD500 with tail registration N4QX .
A routine patrol is conducted at speeds of 25-30 MPH in which, the crew onboard the helicopter is getting an overall look at the structures of the transmission line and associated hardware. The helicopter may at times hover at certain locations during these patrols. An infrared (UV/IR) patrol is similar to a routine patrol in terms of speed but special equipment mounted on the bottom of the aircraft is used to get a detailed look of the conductor, shield wire, and their associated hardware.
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.
