the HSI is done to P&W specs, right?
so how is the Covington HSI different the one done by Dallas? I have no dog in this fight. My engine is currently being overhauled. My mechanic got the same quote from Covington as Dallas so no price advantage. We went with Dallas because they have a shop in NC. His opinion is that they do equivalent quality work.
Paul, once complete please share with us what your total overhaul cost.

Interested too, I'm about 400 hours away

Way to much "this shop is better than this shop" when the engine work itself should be comparable. Quality of people... quality of experience... that is and can be a huge difference. As Penman pointed out, the folks at Covington are QUALITY people. Small company, Christian principles, truly the type of folks you want to support. Are their overhauls twice as good as the other shops? No. Not because Covington isn't great, but because none of them could possible stay in business being half as good. The liability alone keeps these shops consistently operating at the top of their game. When we talk about overhaul facilities we talk about the DDOF's and the "grey" shops. The DDOF's are required to use Pratt and Whitney parts and the grey shops can and often do use PMA parts. Some grey shops will install parts with cycle limitations that might not make the next event, buyer beware! All of the DDOF shops pay the same price for those very expensive Pratt parts and they don't have a huge markup on them, that leaves labor and there's only so much you can discount that. Can one shop be cheaper by 10% on the same exact scope of work on a PT6 overhaul, with the same parts replaced... probably. Can they be half price? No way! BUT- The premium shops can be heavy handed in what they replace and they won't make the effort to find overhaul-exchange or time remaining Pratt parts unless they are pressured to do so. I managed one set of -60A's through the shop for a client of ours, partly because I wanted to help him out and partly because I wanted the experience. I had someone to hold my hand, so it was pretty easy and we reduced his bill six figures from the original post tear down quote. I saw first hand how many items add up and how big of a difference saving $10k here or $30k here can make. These are expensive components! Best advice, hire someone to shepherd your engine through the shop, these guys all know each other, the engine shops now that the expert will question everything, so they'll play it right from the beginning and things will go well.

Your -64 will be less than a -66 in an 850 or the 67 in a Pilatus on an apples to apples comparison.

You can usually trust them to act in THEIR interest!
This isn't unique to engine overhaul facilities. I trust prop overhaul shops a LOT less.
Paint and Interior? Nothing like over budget and behind schedule.
Avionics? You said 4 weeks... not 4 months.
Maintenance facilities? Even the best will get a little heavy handed in the billing department if the customer isn't paying attention. Plus, I catch a lot of honest mistakes.
I am currently having very strong conversations with Textron over some items they messed up on a prebuy...
We deal with this stuff every day. The reality is there are a lot of variables, a lot of moving parts and a lot of money involved, someone has to manage it all and keep everyone honest.

Username Protected wrote: We all know there's a lot of old wives tales in the aviation world. I get the feeling we might have stumbled across another one. Chip has verified that the seasoned King Air brokers will discount a used King Air if the engine work wasn't done by one of the big name brand shops. Not that it has anything to do with quality or superiority of work. Just the brand name. It's kind of like asking a bunch of brokers if they'd discount the value of a Bonanza knowing that it had been operated lean of peak, and they answer, "Oh yeah, that lean of peak stuff kills engines. No way I'd pay as much." Could this situation be similar? I believe it likely is. That is sort of it... What really came to light here is that Covington is a DDOF shop and no one seems to know it. It's not that the King Air dealers (not brokers) are somehow a good old boy network bought off by Dallas Airmotive... it's that when you're buying an airplane if a DDOF shop did the overhaul or HSI, you know they didn't stick crap parts in the engine. It is really important to point out that of the King Air guys I talked to, and I did talk to several in the last two days, no one had anything bad to say about Covington. They all said the same thing "they're an AG shop" and none of them knew that Covington was a DDOF. The other interesting thing is that none of them have dealt with this because none of them have been presented a King Air with Covington engines to bid. I also want to reiterate that this isn't a "discount it" mentality, they will not buy an airplane with grey motors on it, not unless it's a 40 year old 200 or a cheap 90. The fact that Covington is a DDOF makes the difference, based on that they will be able change the perception. If I were Covington, my website would have TBM's all over it instead of King Airs and I would aggressively go after that market. The King Air world is slow to change, the latest example is the Bendix Aerovue. Great panel... PC-12 guys like Crandall and Penman love it. In spite of a huge effort by Bendix they've only put a few units in King Airs. Garmin owns the King Air aftermarket.

I'm actually working on that right now to put on our website!
It's a long list because we cover most current production aircraft (we even do Falcons now)
Once we have it published I'll let you know. Meanwhile PM for anything specific.
BTW... there are shops that save you money and shops that save you time, few do both!

I don't know that there are shops to avoid, aviation is a very small world, a bad shop gets a bad name quickly.
But, there are considerations to which shop you use for what type of work.
We don't take 10k hour Citation V's to Textron and we don't take five year old Citation XLS+'s to my buddy Rusty in Tyler, even though I think he has some of the best Citation guys in the country.
My friends Frank and Dean at Georgetown Turbines, John Powe at ETXHSI and Gordon Wade at West Tennessee Aviation are some of the best King Air mechanics I know... but we've bought three different clients 2013 King Air 350i's lately and none went to them for prebuy.
It's the knowing where to go for what that is the trick, but that is only part of the battle. I would say communication is the most important aspect, but even then things can and do go poorly. I've heard a bad report regarding just about every shop I have ever mentioned.

Username Protected wrote: almost all TBM's are owner flown and....King Airs are much more often corporate aircraft That's the crux of it, isn't it, the difference between spending your own money and spending corporate money. One group cares about value for the price, the other cares about the blame if something goes wrong. It's fine to save the company money, but if anything breaks during the life of the engine it'll be your fault, it'll be assumed it wouldn't have happened if you'd gone with the big name shop. Whereas, if you went with the highest price/big name option, then you did all you could and it must be just one of those things. Easy decision when you're spending someone else's money.
