Marc_B Posted January 9 Report Posted January 9 @GeeBee I don't understand how they set their price point at all as it's a significant chunk of the price of new speed brakes. I guess because they can?? It's one item that is definitely well overpriced for what's performed. Chalk it up to the good old "liability" cost category Quote

Marc_B Posted January 13 Report Posted January 13 FWIW. Was looking for something else and came across the email from Precise Flight customer support when I asked if other comparable lubricants/greases (specifically asked about Aeroshell 7 as I've seen that mentioned before) could be used on the PF Speedbrakes: Hi Marc, Thanks for your email. We have had customers use lubricants comparable to Aeroshell 22. However, we only recommend using Aeroshell 22. It is very important that it is not a spray lubrication and that you don't overdue the grease, usually about a pea size amount applied with a brush is sufficient. 1 Quote

That tube will last you about 500 years based on the little amount needed. This is the PM schedule for the 2000 Series I believe where they call out AS22 Quote
TheBearFlies Posted February 24 Report Posted February 24 I have about 15 hours on my plane since the rebuild, working perfectly. Quote
Ragsf15e Posted April 9 Report Posted April 9 Lets say your airplane lives in a hangar, rarely flys in the rain and you use AS 22 as directed each year so your speedbrakes work perfectly… are you still required to send in the speedbrakes at 1000hours for “clutch lubrication and spring replacement”? Are ICAs required? It would seem they are based on their name… Quote
JimK Posted April 9 Report Posted April 9 No. There is no requirement for periodic overhauls. Use em until they stop working would be my advice. Quote
JimK Posted April 9 Report Posted April 9 No. There is no requirement for periodic overhauls. Use em until they stop working would be my advice. Also, it was pointed out to me that the link to my Speedbrake annual maintenance video on YouTube didn't work so here it is again and I hope it works this time. https://www.youtube.com/watch?v=YenjFgJ0diY&t=55s Quote

Marc_B Posted April 9 Report Posted April 9 I always thought this was dependent on part 91 vs part 121/135. They are recommendations on the manufacturer, similar to TBO for an engine, and are strongly encouraged for safety and reliability, but not legally obligated for Part 91 general aviation. Quote
PT20J Posted April 9 Report Posted April 9 An ICA will have an Airworthiness Limitations section that is FAA approved. Only maintenance that is listed in that section is legally required to be performed under Part 91. It is rare for that section to contain required maintenance. An exception is the Powerflow exhaust annual disassembly and lubrication. 1 2 Quote
Marc_B Posted April 9 Report Posted April 9 Interestingly enough, the SB100 series from Precise Flight just have simple maintenance recommendations that anyone could follow every 200 hours and don't spell out any overhaul interval. PreciseFlight_SB100_ICA_amend1996.pdf 1 Quote
dkkim73 Posted April 9 Report Posted April 9 The big $4000 quantum (ok, stop laughing, TBM owners) probably keeps a lot of us from sending them in for minor quibbles or preventive maintenance. I wonder if Precise Flight might do better in the longer-term to graduate the service a bit more...? not charge max cost for greening them up, but charge more if new parts are needed etc. If it were less expensive I would probably be on board with sending them in for routine preventive maintenance. From what I read and glean on line, they are not Science of The Rocket in terms of troubleshooting and some here have documented obvious handyman type fixes like contact cleaner, etc. But A&Ps, for regulatory-appearing reasons, won't cross that line (understandably).

ArtVandelay Posted April 9 Report Posted April 9 I vaguely remember that you can lubricate the speed brakes without removing them, extending them and using a long thin stick IIRC. Quote

I think this also depends on how long it's been since your speed brakes have seen some love. If they have dried and crusty old grease on the worm drive and gear, then ideally you should clean them up before applying a THIN layer of Aeroshell 22. It's doable to grease from above with a long brush, but not as easy to clean or apply completely around the worm drive. I've used an acid brush, but I've heard of others using a coffee stirrer. Quote
