Standard Industry Practices
Standard Industry Practices
(OP)
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 learnt it at school and use common sense", or is there a reference book (like the SAE manual)which lists SIP's?
Thanks for your reply,

RE: Standard Industry Practices
It has been my experience that what you learned in school or common sense have never been factored into cleaning, inspection or repairs of aircraft components. I for one have never read the reference SIP. My experience has been limited to PWA, GE, CFMI and Honeywell so we may not be working to the same set of rules. As a rule the Repair Manual dictates the specific steps taken. Generally it will refer you to the SPM and by that you have your procedures. When the Repair Manual differs from the SPM the Repair Manual is law. All manuals have specific processes, materials and sequences that must be adhered to. In the case of "or equivalent", you must be able to prove equivalency and it is a good practice to have that equivalency statement on file if you ever get called on it. If you think you can write a repair out of common sense without a DER approved by the FAA, then you are really going out on a limb. In closing, I will not offer an opinion on your question or it's intent, but I am compelled to offer this advice. READ YOUR FAR's. Part's 43 and 145 are the Repair Station's bible. Also be mindful of part 39. Change is constant in this industry, it pays to be aware of your surroundings.

RE: Standard Industry Practices
Expanding on what DJ1958 said, I would recommend FAA Advisory Circulars AC65.9A and AC65.15A, the airframe & powerplant mechanics General and Airframe handbooks, respectively. There is also a powerplant circular (AC 65.12), if you need that too. These are the books, along with AC43.13, where most U.S. civilian mechanics are introduced to aircraft "standard industry practices". Even then, mechanics are always referred to the manufacturers data where ever possible.
I haven't been an A&P for 8 years now and I still look things up in these books, I think you will find them very useful.
Hope this helps.
