The EASA issued an AD on Thursday requiring the replacement of FOHE units on Rolls-Royce RB211 Trent 500 and 700 series engines. This is in response to the crash of British Airways flight 38, a Boeing 777-200ER aircraft powered by a pair of RR RB211 Trent 800 engines, that occurred when the engines experienced a loss of power while on final approach to London-Heathrow. The cause was determined to be ice restricting the flow of fuel through the FOHE, and thus severely limiting the amount of fuel that was delivered to the engines.
The FAA has also issued a similar AD, targeting RR RB211 Trent 800 engines specifically. I find it interesting to note that both governing agencies have issued AD’s for similar engines, but different models. I am sure both agencies have their reasons for requiring changes to be made to the engines they specify, but it doesn’t make much sense that the engines specified by one agency are not also specified by the other.
