this aircraft is perfectly capable on one engine
The Investigation summary of a C90 on a charter that ended up cartwheeling down the main street a few years back had these findings:
1. The left engine failed during a critical phase of the takeoff. The failure was probably the result of a developing problem in the cold section of the engine, which was not detected or corrected due to several compounding deficiencies in the operator’s maintenance system.
2. The aircraft manufacturer’s specified procedures for responding to an engine failure ... stated that the takeoff should be rejected below the ‘take-off speed’, specified as 100 kts. The short flight continued at a speed close to Vmca (90 kts), and the aircraft was not configured to minimise drag.
3. Control of the aircraft was lost in circumstances where recovery was not possible and the subsequent ground impact and fire was not considered survivable.
Yes, that was a C90, and not a B200, but the certification requirements are the same. No matter how good you are, if it goes quiet at the wrong time at the wrong place and you elect to stop you can be off the end with the macho infallibles baying for your blood, or if you keep going, you're upside down in the weeds.
it is not a poor performer on one once the engine is feathered
yes - if you have enough speed under your belt. You might not have enough runway / clearway for this if your wheels are just off the deck.
