An A&P without IA can sign off any inspection on a Citation. Any major repairs or alterations would require an IA to sign the 337 but any A&P can do the work.

This came up the other day about a king air believe in Chris Roans post about his 200
Turbine twins and jets with a maintenance program only need an A&P
There was a nice gentleman who I suspect works for textron who chimed in verifying that is how the FAA interprets it.

[/quote] True, but a HOT is not a major repair.  [/quote] It is not, it's an inspection not a repair[/quote] True and an overhaul of the JT15 is not a major repair

The overhaul of your Lycoming/Continental is the same. A Powerplant mechanic can overhaul it and return it to service

AAAA- Maybe not so fast
As far as the internal blower is concerned I agree No A&P but
As far as the geared engine? I think (IIRC) that no "planetary geared engine" can be done by an A&P BUT a spur geared engine can like the Cont GITSO
I'm going back a lot of years here

I'm going back a lot of years here You are correct, the GTSIO overhaul would not be a major repair, but the G0, or GSO-480 would be. Spur versus planetary gear box.

And that’s precisely how I remember “no-date-Donna” describe it at Bakers. Great to see someone take the initiative to do a hot themselves. In my work world everything gets trucked off to an expensive shop and comes back with an invoice very few owner-operators could tolerate.

A caveat?
As long as you have any special tools required by the manufacturer :-)

Yup, provided it is the M̶a̶n̶u̶f̶a̶c̶t̶u̶r̶e̶r̶'s̶ approved phase inspection FIFY: FAA Approved Inspection Program

BT HEADLINES: TARVER BREAKS TURBINE MAFIA'S OMERTA ! Username Protected wrote: We pulled out five Hot Sections today on stuff that I own. Most of everything was very clean. I like to lay everything out in the hangar and figure out what I need to send out to get overhauled and do the initial inspection. If this subject matter is interesting to anyone, I’m happy to answer any questions and go through the process in more detail. After the first look at everything, I don’t think these are going to cost more than $25,000 each.
JT15D is a simple/reliable engine and fun work on.
Mike

True, which in 99.99 percent of the cases is the Manufacturer's program.

During recent maintenance I was surprised to find a TPE331 being overhauled by a mechanic off to the side of their hangar. I’d always thought you need to send them to a magical overhaul shop with lots of specialized machines and technicians. Turbine engines are amazingly complex and amazingly simple at the same time.
