It has both a differen= t part number, and a different serial number

&g= t; So you are going to create a new w&b from scratch w/o the wheel pant= s?

Correct, I can't reliably compute one due to the discrepancies.=C2= =A0 GIGO

No.

It appears the plane was re-weighed in 2013.=C2=A0 It also appe= ars that=C2=A0 a SV-ADSB-470 (not -472) was originally installed in 2013 pe= r West Air before that re-weighing.=C2=A0 =C2=A0It was removed at some poin= t with no logbook entry that I can find, and replaced with a SV-ADSB-472 in= 2019.=C2=A0 Those are probably very similar in weight and may have been in= stalled in the same location, but I have no way of knowing for sure :-/

The 2017 W&B report we = have from 2017 is not based on the 2013 re-weigh, it is based on a missing = (meaning, I can't find it) earlier 2017 W&B report.=C2=A0 Or so it = says.=C2=A0=C2=A0

I can = create a new W&B report to match the aircraft's current configurati= on.=C2=A0 If you put the wheel pants back on, make an airframe logbook entr= y and calculate a new W&B report.

When a previous W&B is referenced instead of a re-weigh, = all the superceded reports going back to the re-weigh are required to be in= the aircraft records.=C2=A0 ( They should be in any case, but most definit= ely if a revised report is based on calculations using a previous report= 9;s weight & C.G. as a starting point )

Hi Craig,

There is a W&B report in the binder in the aircraft, however = it is not valid.

That report is from 2017 for tail= number N629BV; it does not include known additions to the aircraft subsequ= ent to that W&B report.

It is unclear if the= =C2=A02017 report is for the aircraft=C2=A0configured with wheel pants inst= alled (it is unclear when they were removed without more combing through th= e airframe log).=C2=A0 The 2017 report reflects the removal of the strobe p= ower supply, and autopilot installation.

However, = there should have at least been a new W&B report from 2019 when the eng= ine was swapped out and the ADS-B receiver installed.

Were you able to locat= e a W&B report more recent=C2=A0than 2017?

If = not I see no alternative other than defueling the aircraft and completely r= e-weighing it.

Also, with the addition of a radio = the compass card needs to be revised.=C2=A0 There isn't a compass rose = at S30 ( I think the nearest is KCVO ) so I propose using a GPS augmented c= ompass app on my phone rather than flying the aircraft to another airport &= amp; back.

Let's plan on a Sunday morning pick= up rather than Saturday afternoon so I have additional time for re-weighing= , re-doing the compass card, etc.
