Default Pg 54-04; Flap Position Pushrod

Dropping in my wiring harness this week, going pretty good.

A little snag, not insurmountable, but looking for a better strategy than pulling out my flap linkage.

On page 54-04 it calls for drilling a hole for the flap position pushrod in a specific place at the base of the horn.

Since mine is already installed, there's no angle to get to that position. Possibly, perhaps, I could do it with the horn down in the forward position routing my drill inside one of the ribs.

However, if there is an easier way or an alternate location to install the rod I would appreciate the advice, I'm not sure how the POS-12 flap position sensor is calibrated to that length or if that calibration is adjustable.

Looks like it's the Ray Allen sensor, can be installed any way that gets the arm from 0-100%, assuming I assign values in my EFIS to the various percentages, makes sense.

Thanks! I haven't looked at the gotchas in a while .. going to start doing that with my morning coffee.

Any suggestions against a right angle drill attachment for this job? Perhaps something like this? https://www.amazon.com/gp/product/B013UBXU3E

I've never used one so no experience.

In regards to the flap position indicator I have to say, "enough is enough"
It is easy, I mean really easy to just look outside and see where the flaps are positioned relative to the aileron. For me I used "three screws" When I could see three screws on the aileron i knew the flaps were half deployed. Then the other positions became, all the way down and all the way up.
I like doodads as much as the next guy but a flap position indicator is just additional weight and complexity.
A "count" of 15 would give me full flaps, a count of 7 gives half flaps or if you need a visual, the three "screws. Or if you really need something else then put a stripe on the end of the aileron.

Well, I'd prefer a bar to actuate the flaps but Vans didn't give me that option but what I did get was a sensor, it's got a place, and Stein went through the trouble of wiring it up for me so ...

What did you use that fit?

Some of the ones I'm looking at give me the impression I may end up with a broken drill bit in a part.

Default Drill

I used a standard pneumatic 90 degree drill. I don't know the brand name.

I just went out to the hangar it is a Rockwell pneumatic 90 degree drill. There is one on ebay right now for $75
