It's a long time ago now - 14 January 1969 - since a BUA 1-11 crashed on departure from Milan Linate. The crew heard a bang from an engine immediately after take-off.
There was a third crew member in the cockpit - a Line Training Captain checking the co-pilot. The crew heard a bang from an engine immediately after take-off. This Line Training Captain misidentified the faulty engine and suggested to the Captain that he close the No.1 Engine throttle lever - which he did, and he then shut down the engine.
The aircraft was then force landed on snow covered ground, fortunately without loss of life or serious injury.
The accident investigators concluded that this accident was caused by the crew failing to recognise their mistake, which had resulted in them shutting down the wrong engine (No.1) in error following a compressor bang/surge in the No.2 engine. The crew also didn't realise the No.2 engine throttle lever had inadvertently also been partially closed.
Possibly a somewhat similar scenario to this TransAsia accident with a similar crew set-up of a senior line trainer on the jump seat?
