Bombardier CL600-2B19 CRJ200, D-ACHA
The aircraft was on a scheduled flight from London Heathrow to Dusseldorf. Shortly after take-off, the Engine Indicating and Crew Alerting System (EICAS) gave a “SMOKE CARGO” warning. The crew carried out the appropriate emergency procedure, declared an emergency and returned to London Heathrow airport. Following a search of the cargo hold, no sign of fire or smoke was found and the aircraft was towed to a parking stand where the passengers were disembarked normally. The investigation concluded that the warning was spurious; probably caused by the smoke detector reacting to dust, condensation or electromagnetic interference. This aircraft had been fitted with a new design of smoke detector, which was intended to reduce its susceptibility to these factors.
