A Cougar helicopter flight on route to Hibernia on Monday had to return to base after what the C-NLOPB is describing as a “minor issue."
The turn around was prompted by a problem with the tension adjustments on the one of the flight controls.
There were 13 passengers and two pilots on board.
This is the second time in three days that a Cougar helicopter has run into a problem while in the air.
Another helicopter was escorted back to base on Saturday when the crew got an indicator light showing a fire in one of the vehicle's engines. That turned out to be false alarm.
