New prop, one less AD, and some great customer service from Hartzell
This past December, I was lamenting our options in dealing with AD
2006-18-15, the repetitive eddy current inspections on our Hartzell prop hub. Our prop had been through three overhauls and it likely would not have made it through one more (prop shop did some measurements while on the plane and it was a matter of how thick the paint was as to whether or not it could go through another overhaul). We considered repetitive inspections as well as priced out our options for 2-blade replacement props. We'd ruled out 3-blade options mostly due to the increased cost. After posting about it here in r.a.o (see: http://groups.google.com/group/rec.a...6c816188d4d93), I received an e-mail from Kevin Ryan at Hartzell telling me about their 40% discount on a replacement prop and hub. As it turns out, this was about 1.2 AMUs less than what a local prop shop had quoted me for a 2-blade McCauley prop & hub. My partners and I pondered the options and decided to go with the Hartzell option. This past week we had the prop installed and it looks and works just fine. Yea, for us, AD 2006-18-15 has been terminated. One thing I wanted to mention is the great customer service response from Hartzell. I'd been a little soured on them due to a pretty lame response to my questions of their guy at their booth during the 2006 AOPA expo. My experience in dealing with Hartzell for the replacement prop, however, dramatically turned my opinion around. Kevin provided all of the information for ordering the prop as well as answering a bunch of questions about returning the old prop. It was a very positive interaction and in the end, we received exactly what we were looking for at a substantial discount. If anyone wants Kevin's e-mail address, drop me an e-mail. Unless, of course, you're reading this Kevin and feel like increasing your spam intake by posting your e-mail address. :-) It could be a test of Hartzell's spam filters, eh? -- Jack Allison PP-ASEL-Instrument Airplane "To become a Jedi knight, you must master a single force.

My partners and I pondered the options and decided to go with the Hartzell option. I think the discount ended at the end of September. I considered it as well but ended up doing the ECI. My blades are also near limits. However, I've heard a lot of good things about the new 2 blade composite available from Lake Aero. The price is only a bit more than the Hartzell discount so I decided to continue doing the ECI and if I knick a blade I'll pay the extra 1.5 AMU for the new composite prop. People are claiming 3-5 knots extra on the new prop but the interesting thing about the new prop is that it (in theory) has an unlimited life span. During overhaul the blades do not get smaller as metal blades do so you can overhaul it as many times as necessary. I just had my ECI done at Stockton. $350 plus an AM off work but it only took an hour. The shop has a deal that they use Top Gun's hanger so they can do it on the field. -Robert |

My understanding as explained by a friend/A&P/IA/Part137 guy who is working
with MT to apply one of their models to PT6 driven AirTractors is that the interior hub and bearing work is fairly normal however after the blades are ground they are built back up and finished to original factory specs.
