PROP SYMMETRY?

Did they stop at the same time?

Dem's some big paddles on that riverboat.

On the C-130s I crewed in the Coast Guard, it was a point of pride to set the props in alignment as part of securing the aircraft. Just one of those things the military does to remind the tropps that small details can be important.

I've been known to align the props on the twins I fly, too.

I align my prop every time... it looks better sitting there, and, just by glancing at the plane I can tell if someone or thing has moved it...
When tied down on a ramp you never know if a passing plane clipped it on the way by... IMHO.

Prop is always horizontal when I get done flying... old habits from parking rentals on the ramp... a wing can pass over without a prop strike...

Anyone remember RARE BEAR, configured as it was when flown by Lyle Shelton. I think it used prop blades like those from a P-3. Would make this unique rumble, flying by the Reno grandstands at almost 500mph.

In the winter, our club parks its planes with the props vertical so that semi-melted snow and ice will drip out and not freeze inside the spinner. I've spent too much time with a hair dryer thawing the spinner!!!

They are positioned in the "X" so the next preflight can see into the intake and oil cooler ducts. in the "+" position you can't see in there.

Thanks, Tom. I figured you'd be checking-in. Please e-mail me the Link to the F-24 Restoration Project. It disappeared from my system when old HD data was X-ferred to my new HD. I want to give it to the guys at the FBO at KBXM(the former NASB).

Not much has changed in a long time, I can no longer get in and up date the page.

The "X" position is also the position that you remove the dome and prop, and is the position it must be in to go on the transport stand.

The prop with out dome weighs 1350 pounds, and the dome is about 125 that is why you see the guy with the overhead crane to lift it off.

The dome has its own sling, as does the prop.

Got it, thanks; at least, most of "the whole story" is there.

Hamilton Standard makes a bunch of blades to fit that hub, and there are several hubs of that type, but they are all an independent system from the engine, they do not use engine oil or the engine oil pressure to operate the prop. they run on regular hydraulic oil used in your light civil aircraft (Mil-H-5606) or the new fire retardant type. and have their own hydraulic pump, and valving mechanism, that is controlled directly from the cockpit by the condition levers.

Although there is an overhead crane in Hangar 6, for the removal of this prop they were using a very large pallet truck which had somewhat of a harness and hook attached to the pallet blades.

IOWs they were using a fork lift to get it off. BTDT too

Very bad old habit. Always park a prop with a spinner with a blade pointed down for outside storage so rain water drains out directly and doesn't give a place for rain and dirt/minerals to puddle and start corrosion which leads to early failure.

Good thought.

It's rarely outside, even more rarely in rain. Last time was two years ago on the ramp in Green Bay during Sloshkosh.

(The back window leaks too. )
