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????

 

 

What are the annual purchases and chores for the FARA runway?

Fertilizer, Weed Killer Appendix D

Spot kill Dallis grass, Appendix B

2018 Spring VERY weak Rey growth until March.

2024 mar 8 , volunteer rey, spotty. First mow.

 

April

Blade/Harrow/Roll runway when Bermuda is sending runners

2018  Weed poison very effective at killing DEAD all weeds
except Dallis Grass. Bermuda is slow to encroach the dead areas.

Ant Killer, Worked well 2017

2019,  2200lbs of Rey was way too much. Thick Rey very hard to cut, and out competed bermuda until late june.

Spring Meeting

Cut runway short twice to weaken rye.

Obtain insurance for the next year

 

June

June 7 –  runway insurance expires

July

Mow grass taller because summer heat will  weaken Bermuda grass

August

2023 extremly dry.

MSMA Appendix c (we are not currently doing this)

September

October

2023 bermuda barely visible.  Some cracks.

Fall Meeting, Elect Officers,  Assessment

After Bermuda is weak, blade and harrow Runway, Plant rey (Justin S&F 4530.  Rey.) 2000 lbs

2017 application of dirt was successful at smoothing low spots.
It scalped the runway bare, and no rain from August to
Christmas and this caused very unattractive Rey growth.

fertilizer ?immediately after seeding?

November

Rachel advise 50lb per acre.  500lb.  Annual.

Mix with 25 5 5.   2000lbs.

December.

 

Appendix A – Notes on fertilizer Weed Killer in March:

RUNWAY CARE by Don Pellegrino scan 2017-05-29

Appendix B – Spot kill with Round Up.

Wait until dullis heads are obviously developed.  Spot only 1 head in one in one area.  Do not kill multiple heads in one area.  That produces a large dead area, and Bermuda cannot overtake from the edges.  Only kill heads that have healthy Bermuda bordering. Do not use round up for driveways.

Appendix C –

Notes from Larry’s son: Apply MSMA 3 weeks in a row. OAT greater than 90 degrees.    Spot spray best.  Do not dose. Do not mix heavy. Do not spray heavy. This will weaken the Bermuda, and it should kill the Dallis grass. Mow 2 days after

I wonder if we should not even apply MSMA to the ditches?

Appendix D

Use a different weed poison each year.

VQ-BYT squawks at PBI

B



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.1483199000798-708599262

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.
