Two small observations responding to comments above;
First; I don't understand the use of the word "spectacular" connected to failures of carbon yacht masts; they just break, exactly like aluminium ones do if a stay breaks or the tensions are set up wrongly.
And second; many years ago (late '70's) the FAA and CAA gave a mandatory mod on TPE 331 engines (up to a certain production number) a 4-year compliance period when it should have been 6 months or less, solely to allow the mod to be done on next overhaul, to avoid grounding the large fleet using those engines. Safety gave way to "commercial reality". Maybe things have changed for the better, maybe not. But no-one should assume that any National Aviation Authority will not give way to commercial pressures, and that applies to FAA and EASA.
