The AMOC approval is for model 757-200 series airplanes converted to freighter by STC ST01529SE with the Simmons/Goodrich FQIS System installed.

Beaverton, OR., June 16, 2021 — Precision Aircraft Solutions received FAA AMOC approval on FQIS (Fuel Quantity Indicating System) modification. This modification increases separation from surrounding system wires from the FQIS processor to the center wing tank penetration. The entire length of the new FQIS wires will be sleeved with TFE tubing, to address areas where increased separation is not possible. Accomplishment of this service bulletin will help to prevent possible sources of ignition caused by hot shorts to surrounding wires. If this service bulletin is not done, a hot short to the FQIS wires outside the tank in combination with an in-tank wire/sensor fault to the structure, can become an ignition source inside the center wing tank.
