Throttle/Prop controls become stiff, seizing up approx 9 mins from landing. Pilot reduced power on that engine as much as possible and conducted a normal landing with shutting the affected engine down at the flare.
Initial investigations show an exhaust clamp had failed allowing the exhaust to slightly separate behind the carby-heat shroud which forced the hot exhaust gas onto the affected cables.
Further examination ongoing.
