All the other flap and aileron control hinges are faired on 42 wings. Why not this one?
Why no flap hinge cover?

Re: Why no flap hinge cover?
Covers (fairings) for the aileron and inboard flap linkage levers weren't added until the DA42-VI came out -- previous DA42 TDI and DA42NG aircraft don't even have those.
I'm guessing that when Diamond did all of their testing of "aerodynamic clean-ups" for the DA42-VI model, they discovered that covering the outboard flap levers did't make enough drag difference to bother with.

Re: Why no flap hinge cover?
None of those are hinges.
The faired ones are control rods.
The unfaired one is a mass balance.
I guess adding a fairing would necessitate an increase in the balance weight which would in turn require further certification and the requirement to have different weights available along with the risk of someone fitting the wrong one. Probably more trouble than it was worth.

Re: Why no flap hinge cover?
Shame on me for calling it a hinge. I should have known better
