When they had vibs and smoke in the f/deck they shutdown that engine and it cleared. Unfortunatly they could not see the vib indicators clearly due mainly to the smoke and shut down the wrong engine. The vibs and smoke cleared because they put the running sick engine to idle while they did a power off descent on a divertion into their homebase at East Midlands. The engine fault did not show at idle and only when they put power back on did they realise their error. The LCD display unit on that a/c has very small engine vibration indicators, less than an inch dimeter and more importantly there are no latching warnings to say when an engine vibs have gone over a pre set level. With smoke in the flightdeck the displays could not be seen clearly and when the vibs and smoke cleared there was no exceedance warning to say which engine had been in trouble. All a/c I can think of have some form of latch on the vibs system, though this can be reset. I dont know of any follow up action on this one. -- john relph.
