Boeing 747, Netherlands 4 October 1992
No written supplemental analysis is available yet. The accident occurred during the approach after the two right hand engines dropped of the wing.  To the opinion of AvioConsult, out of control due to not observing the requirements and conditions for VMCA2 to be valid was contributing to the cause of the accident. This is thoroughly explained in the report Airplane Control after Engine Failure, presented above.
