I would call it that, A spade is a Spade. Until TBO is backed up by a Reg of some sort and not documented by most all manufacturers manual as a Recommendation, the shops exposure is minimal. The liability really gets tied on with the Overhaul though. Shop ties itself to that accessory for Two years.

You were lied to about the liability part. Sorry to say that, but it’s true.

Looks like it’s a crack in the paint layer. Don’t really wanna downplay that as you now have a week area in the composite layers(paint and filler) that will allow it to flex and let moisture in. Not good.

$3K as Removed

Actually Yes, but not will GA aircraft props. I have some sets of Exchange props for Metroliner, King Air 200 and King Air 300/350 that really minimizes downtime for some Part:135 operators I work for. GA props are tough to Core because a fella may take your exchange then have to turn around and buy brand new blades for the Core to make it whole agin, and with programs like Hartzell has with TopProp it literally costs more for those two blades than a New TopProp STC.

I send them back with the propeller. If I replace a part, you will get the scrap parts back.

Alan may have Something. i don’t have anything at this time

Looks like I’m a little late to the party guys. Many Thanks for the positive accolades..

A broken pitch change knob on the blade. Not something you see often, but I have seen it a few times.

Give me a Call 870-630-8166 May be able to answer some of your Questions

214 shouldn’t have oil in it, if it does then the hub is filling up with engaging oil, which isn’t good. Is the oil coming from the base of the blades?

I haul them on Tires as well, seems to be the safest way to go about it.

Someone say Rocket?….;) HBZ gonna be a trip to the SE. McClung Aviation has taken care of Both my Mooneys (F an Rocket). Very good shop, knowledgeable an Fair.

Actually your propeller hub is Non-Suffix. Its actually supposed to have a one-time tear down inspection performance. At that time the Hub Serial number will have an E stamped. After that the 100 ECI inspections start.

Those little suckers are getting hard to come by serviceable. Use to have several of them years ago.

Believe it or not there actually is a few reversing recipes out there. There are some P-Barons that have Hartzell props with a full beta system just like a PT6 prop would have. Not sure if all the details with Is needed on the engine to make it all work. The props are the older clamp style propellers that are heavier than there aluminum replacements.

Always really cool. IMO the Rocket has the best cooling of any piston pounding single bug smasher I have flown

I personally lean towards #5 after years of experience with it. The NYCO is brand new an the jury is still out. Seems to de doing good so far though. Now that Aeroshell Grease is almost unobtainable, we may only have NYCO to use pretty soon.

Looks like grease coming down the blade. May have a reseal in your near future. While having it done ask your shop to comply with SL #293 Rev 1. ghats the use of the Turbo Prop blade Orings, they tend to last forever

Unless your just itching to spend $11K on a new prop, I would definitely have that propeller checked out. If that’s the F7666A-2 Blade you may possibly have the material to O/H that propeller an save yourself $9500. just my thoughts

As far as I know Hartzell only Offers a composite for 20R’s an 20TN’s an it is a great propeller, except the Price tag. MT makes a good propeller an it’s lite weight which always helps on the nose of a plane, but the lack of North American support an the fact that none of them can hold their own fluids in is a deal breaker. MT like a McCauley uses the same blade pocket design(early MT’s actually used McCauley hubs years ago) but weather it’s the type of grease or the Oring Compound MT utilizes in that Union, they are prone to leak in short order.

Normally we don’t have issues with props fresh out of the shop, Very humbling an somewhat embarrassing. However it’s those instances when you have to step up to the microphone an make good on the deal. Appreciate your patience while the situation was Handled.

Unfortunately I don’t have anything to offer. Why does a blade need to be replaced?

I don’t Have a Hartzell on my Rocket yet, but a STC for one sure sounds good. Your Rocket Sir just like every other Non -MT Converted planes will have a McCauley C505 CS/Feathering propeller, an it has No external pitch change provision. Have actually seen an issue like this but it wasn’t on a Mooney, Fortunately for us though it was on a Cessna 414 Chancellor New engine(reman) an O/H Propeller, High MP an Low RPM At the end of the day it ended up being the oil transfer bearing in this guys situation, there was to much clearance when the engine was assembled. With the Feathering Propeller you have what’s called a Latch or Start-Lock, this is in place to keep your propeller from going to feather at shutdown. The Latch angle is normally in the 3 to 5 degrees more aggressive that your low pitch(takeoff blade angle). So at startup your propeller has to get 3-5 degrees flatter to makes its published blade angles, which means fully compressing two giant springs that when not installed are almost as long as one of the propellers blades,(will provide some pictures below)takes a lot of pressure for this to happen. If your not able to flatten the prop out at startup that will yield a higher than normal MP followed by a lower RPM because you have to much Angle. The engine is normally sluggish to spool up an won’t get near the book RPM, but it will buildup RPM 300ft or so on the takeoff roll. The problem was found with a pressure decay test between the Governor an propeller. The Gov comes off an a block off plate is installed where air pressure is used to actuate the prop an measure how long it takes for the pressure to decay. If the decay is to much the Hydraulic system can overcome the Cwt Weight an Spring forces to acquire Low pitch. These props require a lot of pressure to actuate.

Aeroshell #5 is a far Superior grease to #6. I see propellers torn apart everyday that have been serviced with both, an it’s a nobrainer. The props with number 6 usually have very little line remaining an the Parts kit is usually much more expensive from Steel on Steel actuations. When the new style #6 was introduced 3-4 yrs ago our shop had to warranty 14 propellers, most of which were 4 blade King Air props because this stuff was freaking down into oil so fast the Orings wouldn’t hold it back. Jury is still out on the GN3058. It’s showing signs of being a good grease, just haven’t seen many props for maintenance yet that used it. letter from Hartzell below
