Cullen & Sons <br /> 330 East Delavan Dr <br /> Janesville, WI 53546 <br /> **DETERMINATION OF NO HAZARD TO AIR NAVIGATION FOR TEMPORARY STRUCTURE** <br /> The Federal Aviation Administration has conducted an aeronautical study under the provisions of 49 U.S.C., <br /> Section 44718 and if applicable Title 14 of the Code of Federal Regulations, part 77, concerning: <br /> Structure: Crane Crawler <br /> Location: Madison, WI <br /> Latitude: 43-09-22.50N NAD 83 <br /> Longitude: 89-17-05.30W <br /> Heights: 997 feet site elevation (SE) <br /> 190 feet above ground level (AGL) <br /> 1187 feet above mean sea level (AMSL) <br /> This aeronautical study revealed that the temporary structure does exceed obstruction standards but would not <br /> be a hazard to air navigation provided the condition(s), if any, in this letter is (are) met: <br /> **SEE ATTACHMENT FOR ADDITIONAL CONDITION(S) OR INFORMATION** <br /> This determination is based, in part, on the foregoing description which includes specific coordinates, heights, <br /> frequency(ies) and power. Any changes in coordinates, heights and frequencies or use of greater power, except <br /> those frequencies specified in the Colo Void Clause Coalition; Antenna System Co-Location; Voluntary Best <br /> Practices, effective 21 Nov 2007, will void this determination. Any future construction or alteration, including <br /> increase to heights, power or the addition of other transmitters, requires separate notice to the FAA. This <br /> determination includes all previously filed frequencies and power for this structure. <br /> This determination does include temporary construction equipment such as cranes, derricks, etc., which may be <br /> used during actual construction of a structure. However, this equipment shall not exceed the overall heights as <br /> indicated above. Equipment which has a height greater than the studied structure requires separate notice to the <br /> FAA. <br /> This determination concerns the effect of this temporary structure on the safe and efficient use of navigable <br /> airspace by aircraft and does not relieve the sponsor of compliance responsibilities relating to any law, <br /> ordinance, or regulation of any Federal, State, or local government body. <br /> A copy of this determination will be forwarded to the Federal Aviation Administration Flight Procedures Office <br /> if the structure is subject to the issuance of a Notice To Airman (NOTAM). <br /> Page 1 of 6 <br />
