No fatalities or major injuries have resulted from uncontained engine failures in BAe146 / Avro RJ aircraft.
I was under the impression that many years ago a -200 aircraft suffered an uncontained failure of the fan on the number three engine. Several people have told me that this resulted in the death of the passenger sitting adjacent to it.
On the ALF 502 the fan has a overspeed protection system designed to cut the fuel off when the fan speed reaches 104%. Unfortunately in this instance there was a fault in the system and it didn’t overspeed shut down, so the fan sped away to destruction.
As a result of this incident all 502's were modified to incorporate two overspeed systems that are independent of each other.
I have seen the aircraft in question and it does have a couple of large skin patches adjacent to the number three engine!
