MD-RA requires avionics shop to test pitot? - Page 2

The avionics certification is NOT an airworthiness issue and should not be a condition for you receiving your C Of A. Fight it if they try to tell you otherwise! It is quite clear in the CARs ... This is true for certified A/C as well BTW.

Let us know if you find the article ... Maybe it's on their web site?

Found the article ... You're right, it says that the MD-RA will want the avionics inspection done. Either the article is wrong, or the article is right and the MD-RA guys are wrong.

For what it's worth, the list of inspection documents on the MD-RA web site make no mention of this ...

I'm not sure my guy said that the pitot/static test before first flight was in effect now, but it is coming down the road soon. As for not being listed as to what the inspector will look for , this is very new to them as well.

Pitot/static I can maybe see as this relates to basic speed and altitude .. but the encoder/transponder part, and the altimeter correlation check, you should not need.

Well I re-read the CARs, and I'm not seeing it. There is a requirement, but only as it applies to aircraft that enter certain airspace ... can't find it anywhere in the basic airworthiness sections:

Quote:

13. Altimetry Devices
(amended 2007/12/30; previous version)

(a) Altimeters and other Altimetry devices installed in aircraft operating under Instrument Flight Rules, or under visual flight rules in Class B and C Airspace or Class C and D Airspace that is designated as "Transponder Airspace" shall be calibrated at intervals not exceeding 24 months, to the parameters and tolerances outlined in Appendix B of Standard 571, or to equivalent standards acceptable to the Minister.
(amended 2007/12/30; previous version)

(b) For the purpose of this section, the term "altimetry devices" includes any air data computer, or other barometric device, providing a flight crew station, or an auto pilot, or automatic pressure altitude reporting system, or altitude alerting system with altitude data derived from static pressure.

(amended 2007/12/30; previous version)

14. Air Traffic Control (ATC) Transponders

ATC Transponders, including any associated altitude sensing reporting mechanisms, where installed, shall be tested every 24 months, in accordance with Appendix F of Chapter 571 of the Airworthiness Manual.
(amended 2000/12/01; previous version)

All he airworthiness section says is that you must have an airspeed indicator and an altimeter, and that hey must "serviceable and functioning".

I see there's a Class D CZ around the Sault airport ... is it Transponder airspace?

Not sure of the Sault's classification, but I know how to find out. The COPA flight meeting tomorrow night has the Tower Manager as the guest speaker. I'll find out his thoughts on the subject.

If you check on the MD-RA website and click on the tab for " Complete Construction Procedure" then scroll down to the Final Inspection 6.6 (3) it says that in addition to the transponder requirements there is Altimeter testing required which shows a change as of Jan 11 2015. The link to the CAR says this:

b) For an altimeter:

(1) Test by an approved maintenance organisation in accordance with the following............

That could really be a problem for someone building in the boonies....

During the Tower managers talk last night the subject of Transponders came up, they are not required to enter the Class D control zone at the Sault.

I'm going to send an email to MD-RA and see if I can get a firm answer.

For those of us who are using experimental EFIS equipment as our primary source of altimetry, this is a large and unacceptable shift in onus. The term "Approved Maintenance Organisation" is very specific in its scope. What this means for us is that a brand new, factory-calibrated EFIS will no longer be acceptable for altimetry because none of the EFIS manufacturers possess a Canadian AMO approval.

Now picture the fun and games we are going to have when we try to send our experimental EFIS into an AMO which, heretofore, has only seen TSO'd steam gauges. We're going to have to provide all the necessary external wiring harnesses etc so the whole EFIS system and ADAHARS can function as a system.

The net effect is that we are going to be required to pay the rather large $$$ required to bring an AMO up to speed to test our equipment on their bench, or pay the even larger $$$ required to bring an AMO's mobile testing equipment to our aircraft. For those of us in rural areas, get set for some sticker shock.

Sounds like it's time for EAA Canada to get involved in this conversation.

As far as getting the pitot and static system tested by an approved shop has not changed. Way back in 2006 I had my Dynon system tested in my new SuperCub and I had our RV-10 done in 2012 with a dual Skyview no problem.
The only change I see is having to pay for six hrs travel time and 600 km milage fees, rather than a fun 3/4 hr flight (times two).
