Bell Jetranger puff of smoke from exhaust during flight
Does anyone have any idea what caused this?
While coming to land, once a hover was established, a large puff of white colored smoke came out of both exhaust stacks.There were no indications that this happened.
It was only spotted after watching a video that was recording the landing.
After reviewing a video of the takeoff of the same flight, a small puff of black smoke (looked like carbon) was observed during the hover transition to takeoff. The flight was about 15 minutes long and another 15 minute flight that occurred after the smoke flight showed no smoke events.
Has any body seen this happen on JetRangers or other helicopters with RR250-c20s in them?
