Maybe. There are NULL adjustments for pitch and roll that do not even require the laptop (i.e. terminal) connection. Also, if the flight computer was removed and reinstalled during this process there are these admonitions:nrenno wrote: ↑Sun Apr 05, 2020 5:15 pmThe KAP 140 of my 2005 DA40 started giving a pitch trim error when booted. After reading the excellent comments in this post and trying some of the simpler steps unsucessfully, I asked my mechanic to remove the pitch trim servo. The servo was sent to Duncan Aviation for repair. They discovered that the servo's strain gauge had failed. The strain gauge was replaced and the service was shipped back me and installed in the plane by my mechanic.
After installation the KAP pilots completes the diagnostics without any error. Everything appears to be working correctly, but when the autopilot is turned on in flight, it pitches the plan down instead of holding the attitude. Does anyone know if this issue can be easily corrected via a laptop connected to the KAP 140?
FOR TWO AXIS INSTALLATIONS REMOVAL OF THE KC 140
FROM ITS MOUNTING RACK IN THE AIRCRAFT PANEL OPENS
THE STATIC AIR SYSTEM TO THE AIRCRAFT CABIN. AFTER
REINSTALLATION OF THE KC140, VERIFY THAT THE STATIC
AIR SYSTEM COMPLIES WITH F.A.R. 91.411.
The following information is provided in the event that the o--ring on
the KC140 static port requires replacement. The o--ring is 70
durometer EPDMmaterial, AS568A--006 size. The AlliedSignal part
number is 187--01004--0013. The o--ring should be greased with
AlliedSignal part number 016--01210--0000, Dow Corning 55 o--ring
Lubricant (Mil--G--4343) or equivalent grease.
If you can lay your hands on the installation manual you'll see this and other interesting information in section 2.3 regarding setting stuff at initial and re-installation.
