| Subject: | Re: HS-6 engine needed |
I wrote recently in these columns that it is my belief, and supported by
Doug Sapp, who is almost certainly the leading person dealing with these
aircraft and the Chinese, that the Chinese have categorically said that
there is no opportunity to have engines overhauled, and that there are no
either overhauled or new engines available for sale for the foreseeable
future. No one has contradicted that, so I assume that my belief is correct.
With Aerometal, my partner in Hungary, who overhauls many AI 14 and M 14
engines, we have been keen to get into the business of overhauling Chinese
engines. To that end we bought a couple of old engines to work out the
feasibility of doing this. With over 50 years of experience of the AI 14
engine (of course the basis for the HS-6 engine), we assumed that the
engines would be almost identical, and therefore we would have no problem to
overhaul the Chinese engines. In the event however the Chinese have made a
large number of changes, and we simply do not have the parts to undertake a
proper overhaul. I am as sure as I can be that this also applies to any
other organisation or business, including those in Eastern Europe, but I
would be delighted to be proved wrong!
But I don't understand the issue raised by "topacedave" about approvals,
particularly in terms of installing the M 14 P/PF engines into Nanchang
aircraft. Remember that these aircraft are totally uncertified and can only
be operated on some form of "experimental" or similarly restricted basis.
Fortunately, you Americans have the huge advantage of a very relaxed
environment in the "experimental" category that you have. Sadly we Europeans
are much more controlled, and in many European countries it is quite simply
not possible even to fly a standard Nanchang.
But given that the aircraft is not in any way certified, it isn't correct to
say that changing to an M 14 engine "would not be approved", since the
aircraft itself is not "approved" in many countries. We have a UK customer
with a Nanchang who applied to UK CAA to install an M 14 P engine. Of course
this is a widely done conversion, and relatively straightforward insofar as
the engine is the same size; weight; fits onto the same engine mounts et
cetera and the detailed changes are relatively small. But the UK CAA
insisted on an incredibly detailed technical analysis of engine mount loads;
vibration analysis; cooling examination before giving their permission, but
in the end this was done and the conversion was approved, and indeed the
aeroplane is flying successfully today.

Gentlemen,,, it will become a huge problem as time goes on if there are no
overhauls, or replacement engines for the HS 6A engine,, even motor
replacement parts,, I experienced this a couple years back, I had one being
overhauled in China, until they parked it half way completed, to busy for
there own needs.
If the only options are M14,, there are many countries that this motor would
not be approved,, even finding used engines sitting around becomes pretty
expensive investing in labour etc, to get a few more hours in.
To which may be difficult to sell with engines,,,, David

Been there, done that, wrote about it back then (1998). I changed pitch and
fudged prop governor to yield 2600 rpm, just to gain an edge in a grudge
race. Worked great, top end went from 157 kias to 170 kias and I won the
race That's when I realized I could get serious speed out of the air frame
with some areo cleanups and M-14P power.
Sounds simple but I also re-jetted the carb and increased manual mixture
for top end cooling. The race looser, a Seneca driver, noted black smoke
coming from my stacks as I faded to a dot in his windscreen.
Over the years, a few other guys have modified their Huosai's for airshow
work. I believe Greg Medford in AZ had an extensive hop-up on his engine.
Knowing my engine was well worn, I reverted back to normal settings and
within a few years replaced with an M-14P. Never looked back.
I do have a new HS-6 governor I don't need and carb I went thorough with
new gaskets and modified the split plenum into a single, polished camber.

I made some direct inquires with contacts in China this week who confirmed no zero

them) but all spares are there for ongoing repair.

Sorry, Martin, but to avoid any misunderstanding, are you saying that there
are no spare parts available, simply because the Chinese are using them for
their own overhauls? Certainly that is my understanding but it would be good
to have confirmation.

Hi Richard
I was informed parts for the HS6 are readily available from China for ongoing repair/serviceability
but no zero time core engines at this time.

Additional comments for HS 6 Engines.
The USA FAA, like you have indicated fall under Experimental Category,, Here in
Canada, they classify them under Special Airworthy Certificate,,
Not like the FAA, CJ-6 considered a certified aircraft, meaning in theory parts
are required to be original,,
Now that being said, there are a few that have installed the M-14,, And one being
installed as I know, and is being followed by a Transport Inspector,, which
if all goes to plan, will be excepted as a legal install.
There is also a group of war Bird owners in discussion and negotiating with Transport
Canada asking for some changes to the Regulations, to allow us to install,
replace parts that may not be no longer available or being produced due to
no longer in production, etc,
such an item would be the M-14 as an example if the HS 6A engine could not be overhauled,
or produced any longer,,
As far as parts, Yes Doug Sapp can supply most parts,, any shortage of existing
HS 6 engines, will become a serious set back to many Aircraft & owners,,
If some one other then China, could overhaul these engines,, its to have availability
of all the required parts, knowledge, and overhaul manuals,, & tooling..

That doesnt sound dissimilar to the UK CAAs Permit to Fly. That said, we are about
to move to the Light Aircraft Association for oversight (the equivalent of
the EAA) so that will hopefully lead to greater flexibility. It will certainly
lead to (slightly) lower costs.

They sold 6 to the Air Force in Sri Lanka last year for the modest price of US

for their existing aircraft!

I would add that they informed the Sri Lanka air force last year that they would
no longer support the engines. In January we installed an M14P in one of their
aircraft. They accepted it and will soon convert more to M14P.

Harv,
About 4 years ago the Chinese sent an HS6A engine to Motorstar in Romania to
see if they could take over the overhaul business. As Richard has pointed
out the HS6A is not the same as the AI14RA. At that time the Chinese said
they did not plan to supply the necessary parts for the engine overhauls.
