      The Duke needs a lot of rudder force on critical engine failure. I wonder if this was a t-prop conversion.

        Do you know if they had achieved Vmc already?

          I think we generally under appreciate how quickly things can go south...(And I say this with much seriousness).

                Useful operations information.....

                Aircraft was N65MY and was Lycoming equipped... https://registry.faa.gov/aircraftinq...Numbertxt=65MY

                Operation
                Beech A60 Duke in 1986
                The Duke was purchased by corporate and private pilot owners. Most were registered in the United States but examples were exported to many countries including Argentina, Australia, Brazil, Canada, Croatia, Finland, France, Germany, Honduras, Iceland, Serbia, Slovenia, Sweden, Switzerland, South Africa and the United Kingdom. One Duke was flown by the Jamaica Defense Force. Many remain in service in the early twenty-first century.

                In reviewing the aircraft in 2008, Rick Durden of AVweb stated, "Built to the quality standards of a King Air, the six-place Duke sported 380-hp, Lycoming TIO-541 engines – rare beasts, those – which means when both come due for overhaul, the choice is the overhaul or buying a small house in the Midwest. The assertive lines of the airframe made for a startlingly attractive airplane, but lead to high costs of manufacture and, surprising to the casual onlooker, horrendous drag. There are those who claim that the Duke was purposefully designed to be about 30 knots slower than it could easily have been on the available power simply because otherwise it would have been faster than the flagship of the Beech line, the King Air. The roughly 230-knot max. cruise speed is only marginally less than that of a King Air 90 and about the same as a Cessna 421, which carries more on slightly less horsepower. While the Duke shares the delightful handling of the Beech line, should pilots have the joy of single-engine operation, they will be up against the highest rudder-force of any piston twin – 150 pounds at Vmc – which happens to be the maximum the FAA allows. Owners report buying a Duke partially because of its looks, but selling it because of the cost of keeping it running. They describe King Air maintenance costs in a piston-twin airframe and recognize that the value of the airplane is entirely dependent on the engines. A gear-up landing means an engine teardown and propeller replacement, along with some sheet metal work. The cost is so high in relation to the value of the airframe that, in many cases, the insurance company will consider the airplane a total loss."[13]

                  But ATLcrew says there is no way we can know this unless we've logged a lot of hours in the Duke. Research is just words and nonsense.

                    My zero hours in the Duke tell me that Vmc is around 80kts.

                      And the engine failed at?

                        According to my research, 79.33456mph.

                          Well, that's about 69 knots, clearly below about 80 knots.

                            In which case the good engine takes you to the place of your death.

                              I'm glad "we" solved this one so quickly.
