I thought a powerful turboprop twin was supposed to be able to fly with only one engine , wasn't?

That one that hit the Flight Safety Center at Wichita, a King Air B200. Only the pilot was onboard, so I presume weight wasn't the issue:

    The twin turboprops will fly on one engine IF the pilot correctly follows the procedures for one engine operation. It appears that instead of following procedures the pilot spent his last 30 seconds of life uttering profanities.

    Video evidence shows that just before the crash the pilot applied considerable left rudder. The correct action to the loss of power in the left engine would have been to apply right rudder. Furthermore, the loss of power emergency procedures call for feathering the propeller on the malfunctioning engine and retracting the landing gear. The King Air crashed with the gear extended and the propeller un-feathered. In short, the pilot did not follow the emergency procedures and further exacerbated the situation by applying the incorrect rudder input.

    They'll fly IF the correct emergency procedure is followed. It wasn't in this case. Simple as that.

    It only has like 10% of the power

    A turboprop is supposed to be able to fly on one engine PROVIDED the aircraft otherwise performs as it should (autofeather, rudder boost) and PROVIDED the pilot flies the aircraft competently (maintain V2 to 400 feet and then Vyse afterward with correct rudder and aileron inputs) and does the correct actions (sets max power, retracts gear, and retracts any flap at blue line or V2 + 9, identify the failed engine, verify it’s failed, autofeathered and not on fire, feathers a windmilling engine, and performs the appropriate shut down drill at 1500 AGL).

    This is a lot to do for a single pilot of a high performance aircraft who’s only owned it for a couple days.

    The only aircraft that is fully automated and guaranteed to maintain altitude on one engine with no pilot input is the Peking Boulevard.

    The article you link to contains the NTSB conclusion that the aircraft was not correctly flown, nor were proper emergency procedures executed by the pilot after the engine failed.

    Read about Vmca here. https://en.wikipedia.org/wiki/Minimum_control_spee... ,if the aircraft was allowed to drop below Vmca at any point after the wheels left the ground the flight was doomed.

    That's usually the case. But it depends on whether all the other flight devices (flaps, spoilers, gear, etc) working as they should..... and that the remaining engine was fully functional...... AND that the crash was not intentional
