It Is my Understanding talking to Hartzell that there is no 500Hr Hub. Harry 321 267-3141 ----- Original Message ----- From: Lowell Girod To: commander-list@matronics.com Sent: Sunday, June 29, 2003 5:01 PM Subject: RE: Commander-List: props --> Commander-List message posted by: "Lowell Girod" Bill; I am coming up on my hub (not the prop) 250 hrs. inspection this year. What is involved in changing hubs and does it apply to the 560E, 3 blade props? I know Capt. Jimbob, has an STP to change the whole thing out for a 'heavy Hartzell', but will this also change both to a 2000 hr. prop? Where do I find out the detail and who can do this?

It has a pretty good article about Ted Smith and the early development of the Aero Commander. If you did not receive a copy, I will mail you one. Best regards, Moe Mills N680RR ________________________________ Message 4 _____________________________________ Time: 02:12:18 PM PST US From: Derek Monk Subject: Re: Commander-List: Was this commander mod ever successful? --> Commander-List message posted by: Derek Monk I'm sure that Sir Barry will prepare a detailed history of this aircraft, so I'll just give you an introduction. The origin of this mod began in March 1967 when a UK distributor, Miles Aviation, agreed to certify for Aero Commander the Turbomeca Astazou XIIM turboprop engines using 680T s/n 1540-6 N6300/G-AWXK. Turbomeca subsequently did not certify the XIIM and Aero Commander, in Oct. 1970, sold (traded) the aircraft to Miles in return for work already done. Miles immediately sold, by prearrangement, the aircraft to Turbomeca who wanted it as a flying test bed for its new Astafan program which they wanted to fly at the 1971 Paris Aero Show. Miles had done some preliminary design work to convince Turbomeca that the 680T would be viable and the deal was done. It was delivered to Turbomeca Nov. 1970. Now over to Sir Barry....
