Not great for RR either, although a lot of the engine is outsourced to other heavyweight indutrial companies. The casing (made by Volvo Aero and Goodrich Corp.) is supposed to retain any explosion - certainly shouldn't permit any part to puncture the wing and drop the casing on the ground. And oh
, the footage of the casing dropped on Batam being manhandled through the street and possibly destroying any forensic evidence of failure
.
So the upshot is, engine components failed, casing failed, RR will suffer, Airbus will suffer, Boeing will be happy (and confirming to client why they should've just gone for solely GE's engines in the 777 and 787). Passengers safe though
Edit: And the same aircraft had an emergency landing previously at Heathrow with an undercarriage fault! Talk about unlucky.
