Canadian North B732 at Edmonton on Dec 29th 2013, engine shut down in flight

A Canadian North Boeing 737-200, registration C-GDPA performing flight 5T-444 from Edmonton,AB to Yellowknife,NT (Canada) with 67 people on board, was climbing out of Edmonton when the crew observed the left hand engine's (JT8D) oil temperature went off scale above limits followed by a left hand engine overheat indication. The crew stopped the climb at about 9,200 feet, worked the relevant checklist, shut the engine down, declared emergency and returned to Edmonton for a safe landing about 30 minutes after departure.

The Canadian TSB reported maintenance found the ducting associated with the vortex dissipator detached causing 13th stage compressor bleed air entering the engine compartment.
