The Swearingen-TEB incident: control issues with twins

Mike

Did you see that Japan is phasing the MU-2 out of their Defense Force?
They lost another one. Makes 4 lost out of 20 they started with (20%
crash rate).

Any twin can be banked into the dead engine and controlled, it is only a
matter of airspeed.

At low altitude, that becomes problematic.

Airspeed and altitude are really the same thing in this arena...energy.
Low, slow and in a high drag configuration is what you don't want.


If memory serves, the Aerostar has only one hydraulic
pump and won't climb with the gear down.

Have you any idea which engine powers the hydraulic pump?


I don't remember but I think that it is mentioned in the Aerostar section of
the Used Aircraft Guide which, unfortunately, is not at hand.

Basically, as Michael points out there are conditions where any twin can
climb on one engine and conditions where they can't (this isn't really true
for Part 25 certified twins) and different airplanes have different
"weaknesses". Some have minimial power, some can't climb with the gear
down, some with gear and flaps. The reason for all this is that
manufacturers keep increasing the gross weight until performance is
marginal. MU-2 weak points are slow gear retraction, big flaps and a wide
gap between Vr and Vyse (about 50kts).
