WKtaylor,
thank you for your reply;
indeed, prop or crankshaft flanges have/can have locating pins to assure a certain mounting position; but I was wondering following what rules this position is determined;
You refer to ignition timing criteria, can you be more precise.

Does anyone has a theoretical or other explanation of what is the best position of a propeller on the crankshaft? Are there certain positions which are to avoid? If you give rule of thumbs, please with the reason WHY if possible.

Which flame spray is called for in the repair? I mean, which powder or wire to use?
Anyway, whether the plame spray coating is for dimensional restoration or a wear resistant coating like carbides, anodizing over a flame sprayed coating seems VERY strange to me, as this process needs really...
Hello Vasanx,
check following website and you will learn a lot on Piston engines, running on Jet A or Jet A1 fuel! Jsummerfield already mentionned it above.

They are FAA and JAA approved and have an STC for the Cessna 182. Other STC's and TC's are in development.

Technically, there is no difference; only the "name" the spec has been changed; a lot of MIL specs are renamed as -PRF- (=performance)instead of earlier names as -L-; -H- etc..
Following my info, there is no problem continuing fluid identified in the old way, of course as long as the...
Hi Clun,
When the hard time threshold is reached, the part/component must be removed from service mandatory.In case of soft time, you must remove the part from service when accessible. E.g. when a part in an engine has a softtime of 10000 hrs, you must not remove the engine from service to be...
I don't know which alloy of Ti you are dealing with; but talk to your metallurgist and ask him if you should have the overheated part checked for alfa case.
Cadmium plating to some high strength ferrous alloys can indeed cause some embrittlement; a relief in an oven can be a remedy to avoid this, like already mentionned in other replies. Another possibility is to have the part first Nickel plated; then Cadmium plated. The Ni thickness must be such...
Interesting literature, maybe old, but nevertheless interesting basic knowledge can be found in NACA reports; see http://naca.larc.nasa.gov/
With the search function, you can sort out the propeller related reports,
good luck
Thank you both for your replies; I'm very familiar with the Ac's you refer to (65-9/-12/-15 and 43-13).It isn't either my intention to do anything without a DER's 8110 when outside the OEM manuals. I found the reference "folowing Standard Industry Practices" in a Boeing Manual...
In certain overhaul manuals, the manufacturer refers to "SIP" or "Standard Industry Practices"for inspection, cleaning or repairs;they DO NOT mean the(ir) Standard Practices Manual!
What do you Americans mean by SIP? Do you simply mean something like "do it like you...
OK Kenneth, it worked with following URL:http://assist.daps.dla.mil ; I went trough the rest step by step; clicking on the address in your last reply doesn't work either; thanks for your help!
Thanks for the reply Kenneth; do you mean this URL?:http://assist2.daps.dla.mil/quicksearch/. It doesn't work either; at least at this side of the atlantic (=Europe)
I am working for an airline since 13 yrs; since 6 yrs, I combine this engineering job with teaching as a guest lecturer at a technical university; It is a good combination to get in touch with the upcoming generation, other companies and to stay in touch with the (hard) reality as well;Only...
Hello,
don't be frustrated; it is a good point that your are reluctant instead of going forward without well understanding what you are doing.
Personally, I have little experience with coldworking of Aluminium. Do you have access to the ASM handbooks? They have a complete volume dedicated to...
