Hartmut, I don't want to sound like I'm making excuses for them.  I just would like to be realistic about it.  First, they had to come up with new tooling to make the extrusions.  Lots of reverse engineering, since the original tooling was gone years ago.  Then the extrusions have to be bent to the proper "V."  This is difficult, considering the spring back of the aluminum.  The bent extrusions then have to be milled to the proper dimensions.  Then they had to prove to the FAA that the new spars were equal to or better than the original ones.  Believe me, this is very costly and time consuming.  Besides all this, they have to pay quite a bit for liability insurance on the parts they manufacture and sell.  Also included in the $9000 or so price is the cost of drilling out the rivets from your old wing attach fittings without damaging them, magnifluxing them to assure that they are ok, and setting the 5/16" rivets in them without upsetting the rivets.  I'm sure that Univair invested far more than $100,000 to gear up for this production run, and it will be a long time before they see a cent of profit from the sales.  I'm actually surprised that the spars are only about $9000 each.

Syd.

Admitted I am exagurating a bit here, but How the heck do you explain the newly built 10k center spar?

What are the costs involved?

 

They've got the jig, the steel and aluminum pieces you need are worth max. $250. Now add the costs for a worker that rivets the stuff together. 4 hours of work @ 100 bucks an hour, add costs for shipping and other expenses - a center spar should not cost more than 1500 Dollars to produce.

I really would like to know where the costs factor comes in here. What is up with this company? I am having the feeling they are overpricing us because some executives are working on their early retirement.

Not true.  I've been through their factory twice.  They are producing many new parts.  Not all of them, but many of them.

Univair is just selling the parts left over from the 50 year old stock for ever rising prices.
