Silver oxide “salts” in jet fuel

 

New to me (2022)

 

Problem that reduces resistance on fuel probes and wires, resulting in increased ability to make house payments.

I think i have observed this two times.

 

1 falcon 900ex 2 months following a possible over application of BioBor.

 

Result was 7 condemned probes in the wings.  I could not save any of the 7 probes by slosh/clean/dry/repeat method.  Very unusual.

We have positively identified the correct nose arm for the F900/F900ex series.
The previous numbers are incorrect, as it refers to gear retracted.arm.
The confirmation came in the Loading Manual drawing , attached to this email.
Could you please change the nose arm to -287.57 on both reports and recalculate.
