I think from what I've read over the years that there were problems with
the installation rather than the engine. Been a while, but when the AF
first admitted the problem, it sounded like the problems were peculiar
to that airframe.

As I recall, and memory being what it is, there was a fuel starvation
problem which most likely had to do with the fuel delivery system (lines
including routing, etc) rather than the engines themselves.

Sorry for the cross postings, but I felt this issue was worthwhile. See
below an email sent to several news agencies. In addition, a letter is
in the draft stages to Sen. Jim Inhofe, who is a member of the Senate
Arms Committee and a GA advocate. I encourage you to do the same.
"Please review the attached stories regarding the Air Force's disposal
of 110 T-3A Firefly airplanes that cost the American taxpayers
$33,000,000. These airplanes were grounded after three fatal accidents.
It was determined that the airplanes had fuel delivery problems.
http://www.txaa.org/DesktopDefault.aspx?tabid=1554
http://www.af.mil/news/story.asp?storyID=123026857
Generally when aircraft are destroyed, they are disassembled and the
good components are then sold through auction or salvage. The Air
Force, however, has completely destroyed all components, including new
engines and propellers still in the crates from the factory.
My company is an engine overhaul facility which supports the general
aviation market. The engines associated with these aircraft are used in
a multitude of certified and experimental aircraft with very reliable
results and are highly sought after. In fact, we had already begun
inquiries with the GSA on how to bid on these components when these
stories came across our desk.
What a waste of the taxpayer's money!! I feel confident that even those
individuals who don't have a passion for flight would find this type of
activity deplorable. I hope you will give this story your
consideration."

The US Air Force has announced that it will scrap all 110 remaining
T-3A Firefly training aircraft in the fleet. The planes were grounded
in 1997 after numerous incidents and three crashes. While the Air Force
attributed two of the fatal mishaps to pilot error, all three accidents
involved problems with the engine, a six cylinder Textron Lycoming
AEIO-540-D4A5 generating 260 hp driving a three-bladed prop.
According to GlobalSecurity.org, the T-3A's engine had failed 66 times
during takeoffs or landings. The Air Force grounded 57 of the planes on
ten separate occasions due to problems with either engines, fuel
systems, or brakes.

FARs......
A CHT is required for acft with cowl flaps.... FAR Part 23, Sec.
23.1305 b(3)i
If the aircraft doesn't have cowl flaps but the CHT was installed
anyway by the factory, could one consider this a mandatory item
to be left in place should a JPI, or like engine monitor, be
installed? That is, what regulation prevents me from replacing
the factory bayonnet with a JPI bayonnet instead of leaving the
factory sensor in place and doing a plug gasket as most have
done?
I already know about the dual bayonnet adaptor...the question
still remains....why not disable the factory installed unit.
Thanks.
