I’m in the middle of my annual and the stab.horn is due. I have also just finished Bill Creech’s book.
So I’m confused about if putting in the Aussie horn eliminates the horn AD (actually changes it to a lesser/easier inspection every 100hrs, according to Bill Creech), or are you still stuck with the 10yr then 5yr requirements.
In reading the full AD with all comments I was left with the conclusion that the FAA was not really sold on the Aussie horn as it only addresses one small part of their concerns. And that even if you installed it, you still only got 10yrs.
I’m new to the group so sorry if this has already been beaten to death, but I could not find much about it in the archive forums.
So my question really is for anyone who has installed the Aussie horn, was it worth it? Also is there a big delay in getting one and the special tools required to install it, that Bill Creech speaks of.
If it turns it into a 100hrs easy inspection, I would do it. If it only buys 10yrs instead of 5yrs (same as installing a new one ) I would pass.

I’m sure you will get some feedback on this but I would call Cliff Wilewski at Heritage Aero, now in Freeport, IL (just moved out of Rockford, IL). He installed the Aussie horn in my Comanche 4 years ago now. I have since sold the airplane but you will get completely accurate info from Heritage on anything Comanche!

Good Luck,

Ed

  Thanks so much, this is what they sent me. The columns don’t line up and paste so well, but you can kind of figure it out. You can just send in your old parts and they will install a new horn and return it. Best case is $1795, worst is $3974 if you need a new tube ($1709) or new bearings ($470), plus shipping. They can turn it in about a week or less. If you fly in they can do it all for another $1000 labor. Extremely nice people to talk to on the phone. Hope this helps others.

  The horn is an alternative means of compliance for the AD. It essentially replaces the part the AD applies to with another part and thus the AD no longer applies. However, the horn has its own set of continuing airworthiness requirements. These consist of a visual inspection every 100 hours. This visual inspection does not require removal of anything from the aircraft.
