Why would a APS-80 in a Westwind II give TRIMA and TRIMB fail?
Aircraft is out of trim at AP disengage, so that means it is a trim problem, not a indication problem.
from “OldAutopilots” cd
In aircraft types that do not provide a horizontal trim rate feedback signal, the APC trim
command + output voltages are fed back into the APC trim rate input ports, and the trim system
is assumed to move when commanded. If the pitch trim system does not move when commanded, the problem will soon be apparent to the crew, because a continuous mistrim
annunciation will result.
The APC-80 contains trim monitoring circuits to determine that the trim circuits and trim system
is responding correctly. The monitors detect opposed trim, inoperative trim, or trim motion in the
wrong direction. The trim monitor provides two trim fail outputs, A and B. Each controls an
external relay, either of which removes power to the trim circuits in the APC and illuminates a
trim fail annunciator. Trim failure annunciations are latching and require correcting the problem
and re-engaging

Check 4 diodes, check trimrun relay
Check Hstab trim time stop too stop.
It is the APC that generates the trim fail, not the APA.
????how does the Main servo tell “out of trim” force….??motor current????

incoming.
1. Number 1 hyd qty reads zero all the time.
2. Occasional AUTO SLAT light, clicking noise from behind panel.
3. APU uncommadded shutdown after start.
4. #2 fuel bypass menelco occurred 1 time, no reoccur since. CND.
On site:
1. Failed number 1 gage verified. Gage due in at midnight. Friday night. Ops test 29-20-00-720-801. New gage S/N 1034 has knarly pinged prints inside the front glass.
2. Suspect WOW Prox going to ground while ac is in flight. Could the clicking noise be the gear handle safety pin? Evaluate Prox detectors. Checked voltage and sensitivity of all 6 Prox detectors.
3. Interestingly, the APU OVERSPEED Menelco was dark when I got to the airplane. Every subsequent shutdown pops it yellow , which is normal. All starts were normal for me.
4. EMERG LIGHTS one bulb out. APU MASTER 2 bulbs out. Replaced bulbs.
5. Crew temp amp motor is making a grinding noise. Goes quieter after 10 min. Info only.
6. Cabin pressure triple gage altitude needle hangs at 3000ft. Tapping panel resets it. Triple gage mount screws loose.
Info only
6. Ron said Mr. Burnes keeps asking about the AFIS Printer paper jamb. Fixed it. It is old and grouchy, like me. Manual print select does not work. Use NAV>AFIS INDEX>NEXT>AFIS CONFIG>NEXT>NEXT>OR>AUTO>ON then choose the services you want.
It will print any of the incoming stuff you want.
7.Minor fuel residue forward of RH ADF antenna inside belly faring.
Outboard of the inboard fuel sump, right wing root.It is a screw or two. the number 10 to 20 screw outboard.The guys left the tanks pressurized, so I am sure that made it worse.
It dribbles into the belly faring and made a puddle on the ground. Looked dramatic, no problem.
If it is OK with you, I will brief Ron to vent the tanks each stop until we get to look at it.8. Tire pressure gage needs cal.
How could the heat ducts become clogged in a Falcon 50?
The foam inside the ducts has deteriorated and fallen onto the outlet registers at the carpet level.
Foam released from some areas inside the ducts
Dime size chunks completely covered some outlets
Smaller pieces
Bosrescope in duct
Possibly the situation was made worse because earlier in the year, the airplane had lost a APU seal and put oil residue in the entire condition system. this may have caused the foam to finally release.
There is foam sheet mufflers on each register, drilled t match the holes in the register. Also deteriorated, but that did not seem to be the worsen problem.
the small pieces of loose foam was blown toward the registers, and completely covered a few of them.
We used a vacuum and a bore scope to clean out the ducts.
the rest of my notes are here

What was the deal on the ALCON battery connector test pin.
.375 is pin
Old go/ no go was :
.370
.378
SB 101 from ALCON
Now company is called redling .
recommended not to use the old .378 tester. it opens the springs too far.
Instead, use a shoulder from a 3/8 inch bolt. Any tighter than slip fit is good.
