FH properly expands the considerations re the speed limit test requirements, but we need to also realize that the FAR’s recognize the establishment of an OEI Vne. Thus for the 92, the twin engine power on Vne is 165 and the OEI Vne is 120, which is also the power off Vne. So doing the second engine cut test is performed at the OEI Vne. Makes the second cut test a lot less eventful than implied above ( the collective position is far lower, thus the Nr decay rate is lower etc ).
I can only comment re the 76 and 92 here, but the power on Vne for both was achievable in level flight, not a dive, so the cut of the first engine at Vne was also a bit less exciting than implied above.
