My understanding is that these STC's are held by Robert and Barbara Williams. Most of the comments that have appeared in this forum over the years involve the inability to get through to Robert with questions and concerns. It is certainly not a lack of expertise on his part. Calls are usually fielded in their home and messages can go unanswered for extended periods of time. Does not result in a warm, fuzzy feeling when spending big bucks.

There have been some good things posted about the DelAir conversions (Harry Deliker), and you may also want to consider that option.

I am having the exact same problem.  My conversion was done in 1996 by the previous owner.  The spinner has cracked and it is, apparently a unique part.  I've talked to "Darlene" who is the only one who answers the phone.  She's nice enough, but has been no help at all.  I finally got an e-mail address from her for Barbara Williams, who is, or used to be the owner.  At one point she answered my e-mail and aased me some questions about the plane, saying she would get back to me with price and availability.  That was on Spetember 21.  However, she has not gotten back to me despite repreated phone calls, e-mails and a letter from me.

I am at my wits' end.  Any suggestions?  have you, by any chance, got a spinner you'd be willing to sell?

That would be too weird for words.  I've probably spoken with "Darlene" a dozen times.  She says that Barbara is traveling and caring for her sick mother in California.  She says that she will get my messages to Barbara, but that is all she can do.

All I want to do is give them some business, and get a spinner that will work on my plane.  Does anyone have any ideas of a spinner that will work with this Bush Conversion?

I'm interested in a Cessna Aerobat with a higher horsepower engine upgrade.  Does anyone know which of the conversions allow retention of the aerobatic certification for both the C150 and the C152 Aerobats?

Good morning,

my name is José Lozano, and I am positioned as Maintenance Director in a Maintenance Center in Canary Islands (Spain), approved under EASA Part 145 regulations, "Aeroclub de Gran Canaria, Part 145 ES-076".

Does anybody know the Mr Delliker e-mail address?

Thanks.

I have a 170B in the shop now with the Doyn (currently owned by Avcon/Bush). The exhaust system is incorrect (other CEssna model). I am in need of a new or serviceable complete exhaust system for this. I have had the same problems getting any calls back or even a phone call answered form the folks in KS.
Any one out there with a system for sale???
I can be reached at 253-939-8750.

I believe you can put a 180 in the older Cardinals per the TCDS as the newer ones had it. I would have to research it though. Where are you located? I am in Washington state.

Can a person get a gross weight increase for an existing Avcon conversion 172H with a Lyc 0-360 1A1 with a constant speed prop?

I installed Bush flap gap seals on my Cessna 180 float plane and I am having a hard time to get it off the water!! Has anyone installed these seals and what was the result??

Jose:

I would be interted in emailing you direct. I went to school in Madrid, and own a paint shop for aircraft here in Arizona.

Your English is so good that you obviously went to school in the USA or England.
