eng1170. The CFM 56 in the 737 is usually quite reliable, but I have noticed it regularly suffers overtemps on climbout especially if there is a temperature inversion .
Acceleration problems are also common, with the usual fix of a MEC change.........which is a nasty job.
BA have 10 CFM powered Busses ( inherited from BCAL) with the FADEC 56-5.
All other Busses have the V2500. Quite a few problems have occured on these. GB airways even suffered a IFSD on a 200 Hr TSN engine .
