Timm et al,
N893MK is still in the shop, since mid-Oct. Getting and installing the new Garmin transponder and upgrades to the STEC 55 (GPSS and Altitude Selector/Alerter) were no problem.
The Stormscope and the Ryan TCAD are another story. Mounting the “boxes” is one issue, but the main problem has been installing the antennas for both systems (3 in all) without compromising structural integrity, potentially rendering my plane un-airworthy. CD wouldn’t say a word of any kind to my Avionics shop for fear of being liable for the results.
My Avionics shop finally got the Regional Technical Director(?) of the FAA involved to lean on CD for some cooperation and for the FAA to okay the install procedure step-by-step to maintain airworthiness. Looks like they are going with an inside the skin install on all three antennas. This sounds odd, but the composite skin doesn’t interfere with proper reception and range of the equipment; or so I am told.
I am supposed to get her back by end of this month with Stormscope thru the Arnav and Ryan thru the 430. After they installed the anunciator for the Selector/Alerter, there was no panel space left for the TCAD anunciator/control, so it will only operate thru the 430. My Avionics shop is also installing the wiring for the TCAD to the Arnav so that if Arnav comes up with the softeware to interface to the MFD it will only be a software upgrade.
This has beem a pretty frustrating experience but at least it was over the winter months and should be ready for spring and summer. Hope I remember how to fly this plane; no time in the air for 4 months now. I am planning to take an instructor along for the return to Reid Hillview and will schedule some refresher hours with him as well.
There was a contribution by Scott Kelly, N893MK, on Nov. 22, 2000, to this forum. Scottannounced that he was on the way to have the Ryan 9900BX installed and would wire it to the Garmin.
Scott, how did this finally work out? Can you give us a report?
Are there others in the field with experience in the Ryan or BFGoodrich systems?
Thanks for any comment.
