If you insist on not moving to a more upscale beer then simply place a large object on the deck to prevent anyone from performing the de-watering process directly over the problem area. This is not rocket science, but then you always do tend to over think things. :>) If you need more direct hands on tutoring in this area I am available to do "on site" seminars providing you have the proper libations on hand.

We have some stock of spare parts with my friend who is flying instructor for Yak-52. Now we are learning the market demand. We found the prices could vary depending on many reasons. We would like to know what the prices would be acceptable for you, possibly after short negotiations we would come to a mutually acceptable, profitable solution. After settling the price we will send you items you need upon receiving payment in advance. We can send you the spare parts by regular mail or in case of emergency, by DHL, TNT, SGS, UPS, etc. Postal charge and custom fee should be added. You can transfer us money by regular bank transfer or Western Union or similar system. Please provide us with the list of spares (and used aircraft) you need and expected prices.

I have to do ground and flight tests before an ACE (Aerobatic Competency Evaluator) and if acceptable to him/her the FAA (FSDO) will send me a 8710-7 card. Different levels are given based on experience and demonstrations, e.g.. 800'agl level 4, 500' level 3, 250' level 2, and level 1- Unrestricted. Your local FSDO would know how they can waiver airspace for you to do aerobatics below the FAR 1500' agl. Maybe your local IAC Chapter would know how, since they have to get an airspace waiver, from the local FSDO in order to allow Unlimited to go to 328' agl during a competition. I hope this helps.

I am an Aerobatic Competency Evaluator and professional air show pilot. I am one of the folks who evaluates and recommends a pilot for a waiver. There are four levels to which you may be waivered and it involves a process of flight and ground evaluation. Level 4 being 800 feet, Level 3 = 500 feet, Level 2 = 250 feet and Level 1 has no minimum altitude limit. Once a waiver is obtained, it can only be used in conjunction with waivered airspace. The term waiver for the pilot is a bit of a misnomer because the card actually reads Statement of Acrobatic Competency. Think of it as a license to perform low level aerobatics in front of spectators. The card is not required for aerobatic flight inside of waivered airspace at sanctioned competitions. The form is an FAA Form 8710-7. W.

Wright" Subject: Re: Yak-List: Question about low altitude waivers ... --> Yak-List message posted by: "Roy O. Wright" Low pass? I'd say that's allowed over other than congested areas. Be careful, I remember reading about the FAA going after someone for flying within 500 ft of a fence... Also I remember reading somewhere that aerobatic flight was defined as pitch in excess of 30 degrees or roll in excess of 60 degrees, but I just searched the FARs and didn't find that limitation. Also couldn't find a definition of "normal flight". I'd say that "normal" varies, i.e., what's "normal" for a Mooney is totally different than what's "normal" for a Yak-55! Section 91.119: Minimum safe altitudes: General. Except when necessary for takeoff or landing, no person may operate an aircraft below the following altitudes: (a) Anywhere. An altitude allowing, if a power unit fails, an emergency landing without undue hazard to persons or property on the surface. (b) Over congested areas. Over any congested area of a city, town, or settlement, or over any open air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft. (c) Over other than congested areas. An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure. (d) Helicopters. Helicopters may be operated at less than the minimums prescribed in paragraph (b) or (c) of this section if the operation is conducted without hazard to persons or property on the surface. In addition, each person operating a helicopter shall comply with any routes or altitudes specifically prescribed for helicopters by the Administrator.

The problem is that, after processing, the end product is the same regardless of the quality of the source material. We have tried the following: Guinness Beamish Newcastle Brown Ale Carib (plain, and with lemon or lime) Corona (plain or with lime) Grolsch Pilsner Urquell Bass Ale Heineken Miller light (it was free so we tested it) Hefeweisen Samuel Adams I can provide an Excel spreadsheet with the test data if you need it. BTW, Guinness is $19/case in the British Virgin Islands but $6 apiece at our local bar. Sometimes it is just worthwhile to deal with customs and immigration just to stock up on test material. And I do have a Rocket Scientist who helps me with my testing so I know it is accurate. > If you need more direct hands on tutoring in this area I am available to do > "on site" seminars providing you have the proper libations on hand.

Far 91.303 speaks to aerobatic flight. Rick B -----Original Message----- From: owner-yak-list-server@matronics.com [mailto:owner-yak-list-server@matronics.com]On Behalf Of Roy O. Wright Subject: Re: Yak-List: Question about low altitude waivers ... --> Yak-List message posted by: "Roy O. Wright" Low pass? I'd say that's allowed over other than congested areas. Be careful, I remember reading about the FAA going after someone for flying within 500 ft of a fence... Also I remember reading somewhere that aerobatic flight was defined as pitch in excess of 30 degrees or roll in excess of 60 degrees, but I just searched the FARs and didn't find that limitation. Also couldn't find a definition of "normal flight". I'd say that "normal" varies, i.e., what's "normal" for a Mooney is totally different than what's "normal" for a Yak-55! Section 91.119: Minimum safe altitudes: General. Except when necessary for takeoff or landing, no person may operate an aircraft below the following altitudes: (a) Anywhere. An altitude allowing, if a power unit fails, an emergency landing without undue hazard to persons or property on the surface. (b) Over congested areas. Over any congested area of a city, town, or settlement, or over any open air assembly of persons, an altitude of 1,000 feet above the highest obstacle within a horizontal radius of 2,000 feet of the aircraft. (c) Over other than congested areas. An altitude of 500 feet above the surface, except over open water or sparsely populated areas. In those cases, the aircraft may not be operated closer than 500 feet to any person, vessel, vehicle, or structure. (d) Helicopters. Helicopters may be operated at less than the minimums prescribed in paragraph (b) or (c) of this section if the operation is conducted without hazard to persons or property on the surface. In addition, each person operating a helicopter shall comply with any routes or altitudes specifically prescribed for helicopters by the Administrator.
