Dennis Savarese" Subject: Re: Yak-List: FAA Memorandum - 8130.2F After reading and rereading the FAA Memorandum and relating it to the posting by WOA whereas WOA says in the announcement, "All former military experimental exhibition aircraft in Groups I, II, and III currently operating and with the flight proficiency 300/600 mile limitations on their operating limitations must continue to operate under the issued limitations until such time they get their operating limitations updated from their local FSDO. However, within the Memorandum it states in the second paragraph, "......Group I, II, III former military aircraft with a special airworthiness certificate in the experimental category for the purpose of exhibition (that's us!) are no longer required to comply with the 300 and 600 nautical mile proficiency flight required by Order 8130.2F, Change 3, Paragraph 158." According to the Memorandum, the proficiency area is eliminated, effective with the Memorandum. Period...end of sentence. The Memorandum does NOT say anything about aircraft with existing operating limitions must continue to operate under the existing limitations until their OL's are changes. The Memorandum DOES say, "Owners/Operators of former military aircraft that currently have a special airworthiness certificate in the experimental category for the purpose of exhibition (that's us) may apply to have the above limitation removed." That paragraph refers to removing the limitation as written in the OL's. It does not mean the proficiency area limitation as currently written in the existing OL's remains in effect until such time as the OL's are reissued with the elimination of the proficiency area. I believe it is intended to mean the proficiency area is eliminated effective with the Memorandum and one must apply to have the OL's revised to remove the proficiency area statement (thus a rewrite/reissue of the OL's) from the aircraft operating limitations. If the FAA wanted the aircraft with existing experimental exhibition airworthiness certificates and operating limitations to have to continue to comply with the 300/600 NM proficiency area, they would have clearly stated that in the Memorandum. But the Memorandum clearly says "Group I, II, III former military aircraft with (that means exisiting) a special airworthiness certificate in the experimental category for the purpose of exhibition ARE NO LONGER REQUIRED TO COMPLY WITH THE 300 AND 600 NAUTICAL MILE PROFICIENCY FLIGHT REQUIRED BY ORDER 8130.2F, CHANGE 3." I will be contacting WOA sometime today and will ask them why they interpreted the Memorandum to mean the 300/600 mile proficiency area elimination only applies AFTER the OL's have been reissued. Why would the FAA want to create an unbelieveable mound of paperwork for themselves by requiring existing OL's to be reissued before the elimination of the proficiency area went into effect? I believe the intent of the Memorandum was to first, announce the elimination of the restriction (300/600 mile proficiency area) and then, at the owner/operators request, update their OL's to reflect the change. My recommendation is to carry a copy of the letter with you just in case you get ramped checked. If you do get into a discussion with an FAA inspector, focus on the words "are no longer required to comply". It does not say "will no longer be required to comply until after the existing operating limitions are reissued."

"EAA and the Warbirds of America (WOA) received terrific news this week from the FAA regarding experimental exhibition operating limitations for former military aircraft in Groups I, II, and III. The FAA has announced a process to allow for a letter of deviation, permitting owners to conduct proficiency flights beyond the 300 nm (piston) and 600 nm (turbine) radius of operations stipulated in a section of FAA Order 8130.2F." Read the entire article at http://www.warbirds-eaa.org/news/2007%20-%2009_18%20- %20EAA%20Warbirds%20of%20America,%20Industry%20Achieve%20Major%20Breakth rough.html It is IMPORTANT to note this is not an automatic authorization to disregard your Operating Limitations. You still need to apply for the letter of deviation with your local FSDO, the procedure of which is detailed in this article. Happy flying!

As it was explained to me, if we presently have a certificated airplane in the Experimental Exhibition category, until we apply for and receive a new airworthiness certificate and updated operating limitations without the proficiency area restriction, we're bound by our present OL's. So if you want to have your OL's updated to eliminate the proficiency area, you either submit your paperwork to your local FSDO or have a DAR do it for you. Using the FSDO is free.

There are FARs that require you have an airworthiness certificate and your ops limits are an attachment to it. If my wife wrote a memo to her sister saying that I didn't need to comply with ops limit #17, do you think the ramp inspector would view that as trumping my airworthiness certificate's requirements? The memo of interest is from one FAA office to another FAA office directing them to remove the proficiency limit of xxx miles from order 8130.2F. I don't believe that it trumps the ops limits requirments either. It does provide a basis for getting new ops limits without the limitation. As you know, when 8130.2f is changed to a more restrictive stance, such as when they added the 300/600 mile limit, it didn't apply to the airplanes that already had ops limits without the mileage limit (the grandfathered airplanes). It seems to me the same applies now. The use of the term "former military aircraft" in the memo is curious. FAA order 8130 says "Many of the aircraft applying for experimental-exhibition..." but the exp-exhibition certificate is certainly not limited to former military aircraft. If I had a IAR-823 or a Yak-50, I'd ask FSDO for new ops limits based on the memo. If they brought up the former military issue, I'd say it was certified under the same guidelines as former military and if walks like a duck and quacks like a duck... I hope you find this useful.

Generation of lift is a very interesting topic. I can imagine a thread on how lift is produced consuming lots of bandwidth as well as producing a fair amount of heat. (These kinds of things tend to produce more heat than light on the subject.) Still, it might be both interesting and enlightening at some level. OTOH, I suspect that there will also be much testosterone and ruffled feathers. Regardless, I think that the topic is really interesting as there are several non-obvious physical properties at work and I would like to discuss my ideas on the matter with someone. -- Brian Lloyd 3191 Western Drive brian HYPHEN 1927 AT lloyd DOT com Cameron Park, CA 95682 +1.916.367.2131 (voice) +1.270.912.0788 (fax) I fly because it releases my mind from the tyranny of petty things . . .

And as to whether or not you need to get a new LOL, your point about it being married to the AC is significant. Your existing LOL is married to your AC. It currently has the 300nm limit on it therefore even tho' the 300nm limit has been rescinded, it still appears on your LOL and therefore is still a part of your OL. If you want it off you need a new LOL issued by the FSDO along with a new AC. It matters because it is still on the piece of paper. You can't change that paper without changing the AC too. Remember, what is written on the piece of paper is *always* more important and significant than the rule book. -- Brian Lloyd 3191 Western Drive brian HYPHEN 1927 AT lloyd DOT com Cameron Park, CA 95682 +1.916.367.2131 (voice) +1.270.912.0788 (fax) I fly because it releases my mind from the tyranny of petty things . . .

The guy in the field doesn't need to know nufin' but, "what's it say in da LOL? If'n it sez it in da' LOL, dat's what matters." This makes it very easy for a guy with an IQ of 80 to be a field inspector. So, to make it easy for the guy in the field to determine if your airplane is airworthy, he looks at your AC which refers him to your LOL. He reads that. It says you have to be within 300nm. He doesn't need anything more nor does he need to think about it. Frankly, I *WANT* a new LOL so I don't have to get into an argument in the field with the field inspector with an IQ of 80 because that is *precisely* the guy I'm going to get when I am ramp-checked. -- Brian Lloyd 3191 Western Drive brian HYPHEN 1927 AT lloyd DOT com Cameron Park, CA 95682 +1.916.367.2131 (voice) +1.270.912.0788 (fax) I fly because it releases my mind from the tyranny of petty things . . .
