Using your position of the fount of knowledge on everything helicopter you accuse me of being wrong and in the process you use words that ridicule me as not knowing what I am talking about.
I quoted directly from the CFR 27-351 which states that at speeds of 0 to .6VNE the pilot must rapidly deflect the tail rotor pedals to attain a 90-degree sideslip both left and right. You expound on the fact saying that I am wrong and I reply with a direct quote from the CFR restating what it says and you still say I am wrong.
My argument stems from what it says in section 4 of the R-22 and R-44 POH which places restrictions on not performing sideslips or flying out of trim as it could result in mast bumping or rotor incursion.
Now we marry the certification requirements of CFR-27-351 with the statements in the POH and what is contained in the SFAR and most likely what is taught in the Robinson safety course.
If what the Georgia Tech report stated that these maneuvers were the root cause of some of the loss of control accidents incurred by the R-22 and R-44 then I reached two conclusions based on the Georgia Tech reports. (Conclusion #1) If the tests were performed during certification they would most likely incur mast bumping or rotor incursion. (Conclusion #2) The test was never performed. Remember that the R-22 was certificated by airplane people not helicopter people.
Here is a question. Supposing the FAA initiated a priority letter to Sikorsky outlining several points that require cautionary or warning status in the POH. And a page was entered into the S-92 POH and this page was not listed in the table of contents and the information on that page was watered down so as not to reflect the true nature of the information. Nor, did the FAA making it an official part of the POH ever sign it off. What is your opinion on this as this is what occurred on the R-22 and R-44 POHs.
The rigging procedure still sucks and yes an R-44 in the UK suffered loss of control caused mainly by flapping extremes on the blades. IMHO caused by the rotorhead design.
