Frequently asked questions.

Q. Who can install the Visual Instrument flap position indicator?

1. Any A and P mechanic or repair station can install this indicator in your aircraft. The form 337 will have to be signed by an I.A. and a copy mailed to your local F.S.D.O.

Q. How long does it take to install the Visual Instrument flap position indicator?

A. Installation should take about 2 hours.

Q. I just received notice of Cessna service letter SEB00-9. Does the Visual Instruments system accomplish the same?

A. Yes. Our system replaces either the A.C. Spark Plug, the Stewart Warner or the Rochester systems with an easier to read display at a lower cost.

Q. Why can I not label my old indicator “inoperative” and look over my shoulder to see what position my flaps are in?

A. FAR Part 91.213 allows you to operate an airplane with some inoperative instruments and equipment. Along with other instruments the flap position indicator is a required instrument and cannot be labeled “inoperative”.

FAR 91.213 and CAR 3.353

Q. Will I need any other parts to complete the system?

A. No. All the parts required are in the kit, the transmitter, the display assembly, the hardware kit and all the instructions and STC paperwork.

Q. Is there any airframe modification required to install this system?

A. No, just remove the old Transmitter and Indicator and replace with the Visual Instruments Transmitter and Display.

Q. Can I replace just the indicator in my airplane?

A. No. Our indicator is not compatible with any of the Cessna transmitters.

When Cessna introduced the electric flap system the first indicators were manufactured by A.C. Spark Plug. Cessna later (around 1965) switched to an indicating system manufactured by Stewart Warner. These two systems were not compatible with each other (see Cessna service letter SE70-12 dated May 28 1970) and Cessna recommended replacing both the transmitter and indicator at the same time. Current replacement parts are now manufactured a third company named Rochester which are also not compatible with the earlier systems (see Cessna service letter SEB00-9 dated Nov 6 2000). THE COST FOR THESE ANALOG REPLACEMENT PARTS RUNS APROX $1,800.00 FROM CESSNAS AND THE WAIT TIME USUALLY RUNS ANYWHERE FROM 12 WEEKS TO 6 MONTHS.
