2012 Annual Report

[Marc CYBW]

2004 DA40, 1600 hrs
- 2 new mags
- battery
- backup battery
- fuel pump
- a variety of small items (gaskets, etc)

plus new static ports which solved AP porpoising on descent.

<sigh>

but, compression is good and no structural problems.

- still thinking of ZAON XRX.

1600hrs that ain't bad.

My 2012 annual report was about four thousand dollars long.

Apples to oranges, since you can do all the work yourself.

And I got away with a case of oil and a few filters

Thanks for posting this. Sounds like the annual went pretty well.

Why did the static ports need replaced? Aren't they just holes? Did they lose their holiness?

The original static port is integral to the pitot tube and suffered from a mild eddy on descent. Only a problem on in flight descent, approaches and NPA as the AP follows the glide path on the ILS.

The "cure" is to relocate the static port, actually ports as they install two, behind the canopy on the fuselage. It requires new plumbing, drilling, install and an updated pitot-static test. About $800 all told.

But it works.

FAA Certification misses obvious design blunder again. Unless no other DA ever suffered from such an "eddy".

A $350 GPS chipset tested seventeen ways from sideways, until it magically becomes a $12000 GPS... but no one notices the freakin' static port is in the wrong place on the airframe.

(Beat head here...)

The STecs are very sensitive to static port location. I read through the install instructions on mine. Even 1/4in out of place and you can get "excessive oscillations"
