Has anyone researched what props are approved for either the Comanche

260 or Aztec 250? It would seem that any prop approved or STCd for

those aircraft could get a certified combination for the -10.

 I spoke with my DAR about this very topic recently.  His take on the

 situation was this:



 ·         Even though my engine was certified, and my prop is a Hartzell

 designed for the plane, the combination of the two had never appeared on a

 “certified” on a production airplane.  The combination to the best of his

 knowledge had only appeared on an RV-10, which is an EXPEIMENTAL airplane.

 Therefore, the combination still had to be considered experimental.  Based

 on this, he said that I was going to get 40 hours, like it or not.

I have a C4B5........the DAR was able to make that connection and only gave

me 25 hours.  I known have 108 hours and still testing.



Now I am working on my mod list for my second annual......lets see...



Second battery of Firewall (for CG purposes and some redundancy)

Move the fuel pump switch next to throttle

Send autopilot back for new screen (second year on that one)



The list is a lot shorter this year.....

In April 2008 my DAR concluded that a certified IO540 and a certified

Hatrzell prop warranted a 25 hour test period; I believe this as done on the

basis of it being an approved engine prop combination as designated by the

manufacturer of the kit.

Pete,



If your DAR is talking about 91.203(b)(3), it says you have to have a

magnetic direction indicator.  Your AFS uses a (highly accurate)

magnetometer to display magnetic heading.  Nothing says it has to be

non-electric, or that it has to be a wet compass.

I spoke with my DAR about this very topic recently.  His take on the situation was this:  

   

·         Even though my engine was certified, and my prop is a Hartzell designed for the plane, the combination of the two had never appeared on a “certified” on a production airplane.  The combination to the best of his knowledge had only appeared on an RV-10, which is an EXPEIMENTAL airplane.  Therefore, the combination still had to be considered experimental.  Based on this, he said that I was going to get 40 hours, like it or not.  

   

·         One interesting point that we discussed.  He said the local FSDO here in Iowa was growing more lenient about the 25 mile radius for testing.  He had discussed the flying speed of the RV-10 and said at the speeds we fly, it seemed that you were always ‘turning left’ to stay within the radius.  Therefore, he had been given leniency to pick an airport 100 miles away and allow flight testing in a straight line to it.  As example, I will likely base out of Ankeny, Ia(ILV) and will request a destination of Burlington, IA (BRL).  In that line of flight, I will fly over Pella, Oskaloosa, Ottumwa, Fairfield, and Mt. Pleasant.  There is always an airport nearby in case of emergency.  Being that I have family in two of those cities, I will be able to stop for lunch during my flight testing time.  

   

·         One other area that I pressed him about was this:  I wish to eliminate the ‘wet compass’ from my panel.  I have dual AFS screens, with dual AHARS, both with battery back-up.  My question was why do I have to have a wet compass?  He said that there was no provision in the FARs to allow it to be eliminated.  He said the rules were written in the 60’s or before, and they had not been updated for current technologies.  He said I needed to write a letter to the FSDO or standards office in Oklahoma.  Has anyone done this?  I’d sure like to eliminate the compass cluttering up the windscreen.  

   

p.s.  As a side note, I have lost my job.  I hope to get reemployed before I am required to sell the plane.  If you know of anyone needing a sales and marketing pro, please let me know.

I am looking for some feed back on the hours that people were required  

to fly off if they had the stock 2 blade Hartzell prop and the DA45 experimental  

engine from Aerosport Power or other know builder. Was it 25 or 40. And if 25  

why instead of 40.  

Just curious. I have heard both ways with this combo. Email me off the list   

if you would like.   

   

Thanks Geoff
