| Subject: | Alaska (was bahamas) |
IN 2008 I and another RV10 friend flew through Alaska with the
Letsflyalaska group that Vic did last year and Tim will be doing. It was
a great trip and really not that difficult because of how well Dale
Hemman, the owner, put's everything together for you. Dale also has a
kit that you can buy with all the info and charts necessary if you'd
rather go it alone vs flying with a group. I think there are advantages
to both.
During our trip I kept a small blog of each days activities with photos.
If you're interested here is a link to my blog. We took a bunch of
photos and posted them all at the bottom of the blog pages.

Keep in mind that cycling a prop is NOT good for the prop or the
engine. Its only purpose is to verify that the prop control and
governor are operational, and a 100-200 rpm drop is more than
sufficient for that purpose. The blades will get rotated as part of
normal take-off and climb. I cringe every time I hear pilots deep
cycling props, as though they want to see if full coarse pitch can
stall the engine.
Latest thinking is to only cycle the prop if the plane hasn't flown
for awhile, and then just a small drop to verify the system is
functioning.

Agree with Kelly...
I fly a Cirrus, which has a single power lever controlling both throttle a
nd prop. Therefore the prop never gets cycled on the ground. To the best o
f my knowledge, the props on Cirrus planes do not leak any more than the s
tandard setup...

This write up was very helpful... My new Hartzell prop had been in the box waiting
to be installed for several years. When I took it out, it was obvious that
the factory grease had separated as there was oil inside the spinner. I re-greased
the prop per the manual and hung it... Several days later there was a thin
sheen of oil coming down the inside of one blade. I don't think I over greased,
but it's possible. Sounds like a call to Hartzell is in order.
Thanks,

Kelly;
I usually check the prop each time as part of my checklist. I just
listen for the slight drop and then go back to fine pitch. You say it
is not good for the engine or the prop. Why??? I can understand
possibly strain on the bearings maybe, but in less than two minutes,
I'm asking the engine for full power for takeoff. I'm trying to
figure out if this is one of those "opinions" or what are the facts
behind this issue.

I've always cycled it fairly aggressively just to see if I can get oil on
the windscreen or the top of the cowling. I figure that if I'm going to
blow a seal or discover a leak, I'd rather discover it before my wheels
leave the ground.
I'm not saying I'm trying to bog the engine down and abusing it, but I'm
doing more than simply looking for a slight drop.

And I've always cycled 2 or 3 times under the impression it was intended
to get warm oil into the propshaft and increase the reaction speed of
the governor / prop. This certainly is the case on a cold Rotax - rpm
recovery is much better after the 3rd cycle than the first - but I can't
speak for other engines.

I think the key is to cycle the prop gently. I hear pilots in the run up ar
ea doing these fast deep cycles and can only wonder how those belts are fee
ling during the cycle. No need to be so aggressive. A slow cycle or several
slow cycles accomplishes the same thing but has to be easier on all the mo
ving parts.

Keep in mind that cycling a prop is NOT good for the prop or the
engine. Its only purpose is to verify that the prop control and
governor are operational, and a 100-200 rpm drop is more than
sufficient for that purpose. The blades will get rotated as part of
normal take-off and climb. I cringe every time I hear pilots deep
cycling props, as though they want to see if full coarse pitch can
stall the engine.
Latest thinking is to only cycle the prop if the plane hasn't flown
for awhile, and then just a small drop to verify the system is
functioning.

my wife has convinced me to do an RV-10 group camping area in Camp
Scholler again for those interested. We skipped last year because it
just became too much work however EAA has made a few changes that should
mitigate that. As in the past I will stake out sites on Tuesday (7/17
this year) the week prior to the show starting. It's done this early
simply because we like the close proximity to the show, entry gates,
showers, etc. Camp sites are "staked out" and marked off at that time
and MUST have a registration tag. If a site doesn't have a registration
tag the EAA security patrol will remove the stakes and marking tape.

$24/night and EAA charges from the first night you're registered through
the end of the show (including Sunday night). If you leave early you
get a refund for unused nights.

tags. That means when you come in you can just go through the express

after the sites are staked out so you know where we'll be.

minute walk to those also. For the airshows we walk straight east
across Knapp St. and onto the airfield. It's about a 10 minute walk to
the flightline from our campsites.

glanced over to see my oil psi at 91 psi. Within a minute it jumped one
more psi and so on until it showed 99 psi. By this time I already
turned back for home, and had reduced power to see if that helped. That

To clarify: McCauley suggested the extra prop cycling to try to get the O rings
to seat, but they did not suggest deep cycling - just enough to move the O rings
a bit.
So far on the 10 I have not had grease issues, and on runup I put the prop back
in as soon as I hear any RPM drop. But I just did my first prop maintenance.
Hopefully I didn't put in too much grease. I pumped until I saw it exiting out
the open hole. It took about what was suggested, as I recall, in terms of the
number of pumps on the grease gun.

Thane -
Any chance you checked the GRT for 0-psi before start?
Check the lead(s) from the sender to the GRT. Check all connections or
splices for a hidden break/intermittent. Pay particular attention to pinch
points, like where the wire runs thru a clamp or tie. Have someone watch
the monitor while you wiggle, tug and push the wire around.
Pull the sender out of the engine, but leave it connected to the GRT. Use
whatever plumbing adapters are necessary to connect the sender to your
calibrated differential pressure gauge. Power up the monitor and apply air
pressure. Compare the known air pressure to that displayed on the GRT. Use
the regulator to vary the air pressure. Does the GRT oil pressure display
change, or is it pegged at 99-psi? Could be a software / setup /
calibration issue. While you're at it, check the old sender just for
giggles.
If the gauge and GRT agree, use plumbing adapters and a long hose to connect
a known, accurate gauge to the oil pressure port on the engine. Perform a
ground-run to verify that the engine is indeed making high pressure.
If the engine is indeed making high oil pressure, check the pressure
regulator assembly. Then consult the engine builder for further guidance.

The issue is the forces the pitch change mechanism puts on the prop
and the engine bearings when the engine is not a full power and has no
air moving through it. Similar to a full power run up with twisting
forces added to the prop blades. On a Lycoming flat 4 or 6 cylinder,
cycling the prop only serves one purpose..to show that the pitch
change mechanism is working. Doing that as gently as possible reduces
the forces involved. Checking the mechanism multiple times a day
accomplishes nothing. Checking it first flight of the morning might
add a little confidence, but really isn't necessary. Nothing bad is
going to happen if the prop stays in fine pitch, that you can't
correct once at a safe altitude to return to the field.

I generally go out and rev the engine to 2000 than do a prop check 5-6
times, I figure it=99s like revving a engine on a vette, I want
people to know I have a high powered engine!!
Seriously though, there is a fellow friend and RV-10 who always makes a
comment about students doing three prop checks before takeoff, when once
is enough. They=99re rentals, who cares!
Here is a piece from Avweb:
How many times should you cycle the prop? If the RPM drops smoothly and
properly, once is enough. The fresh oil will probably cause the piston
to move a good deal and when it comes back to the low pitch stops, most
of the "old" oil will be pushed out. If you really want to feel good, do
it twice, to get even more of that "old" oil out of there. Three times
is gross overkill, in my opinion, but a lot of people do three times, or
more. In reality, there are tiny bleed holes that allow a constant flow
of warm oil to both sides of the prop piston, so even if you take off
with cold oil in there, it will quickly be replaced with nice slippery
warm stuff. On some of the big old props on the radials, in extreme
Arctic conditions, the oil would congeal faster than the bleed ports
could replace it, but I doubt you'll find any modern props with this
problem. I should note for completeness that many of the props on the
big radials might require many more cycles to achieve a smooth RPM drop
when cold. In freezing temperatures, it may take up to ten cycles.
There's a lot more to the mechanism, and a lot more oil involved.

stall the engine.
Latest thinking is to only cycle the prop if the plane hasn't
flown
for awhile, and then just a small drop to verify the system is
functioning.

Some years ago our 182 (McCauley prop) started throwing grease,
not too long after overhaul. Shop took it apart and put it back
together, said they didn't find anything wrong. But the grease went
away. Maybe a dirty O ring. McCauley suggested we cycle the prop 4 or 5
times during run ups to help keep O rings seated.
