Sultan, are you suggesting there was a mixup re the specific tests to be conducted at the power on Vne ( actually 1.11 times that value ) and the OEI Vne as described in Advisory Circular 29-2C Para 29-1505?
As you implied, that testing is rather critical and typically the flight test cards and briefings are carefully ( very carefully ) constructed, so I kind of suspect I've misinterpreted your writing.
