Additional Condition(s)or Information for ASN 2017-AGL-9499-OE Proposal: To construct and/or operate a(n) Crane to a height of 150 feet above ground level, 1082 feet above mean sea level. Location: The structure will be located 0.89 nautical miles west of MSN Airport reference point. Part 77 Obstruction Standard(s)Exceeded and Aeronautical Impacts, if any: Section 77.17(a) (3) by 20/64 feet-a height that increases a minimum instrument flight altitude within a terminal area(TERPS Criteria). The proposal would necessitate Wisconsin Dane County Regional-Truax Field (MSN). VOR RWY 36 increase ISMUZ FIX MINIMUMS S-36 MDA by 20 feet from 1320 feet MSL to 1340 feet MSL. RNAV(GPS)RWY 3 increase LNAV/VNAV DA by 64 feet from 1179 feet MSL to 1243 feet MSL. Section 77.17 (a)(5) a height that affects an Airport Surface by penetrating: Section 77.19 (a)Horizontal Surface by 46 feet as applied to MSN. Preliminary FAA study indicates that the above mentioned structure would: have no effect on any existing or proposed arrival,departure, or en route instrument/visual flight rules (IFR/ VFR) minimum flight altitudes. have no physical or electromagnetic effect on the operation of air navigation and communications facilities. have no effect on any airspace and routes used by the military. Based on this aeronautical study,the structure would not constitute a substantial adverse effect on aeronautical operations or procedures because it will be temporary. The temporary structure would not be considered a hazard to air navigation provided all of the conditions specified in this determination are strictly met. As a condition to this Determination,the structure is to be marked/lighted in accordance with FAA Advisory circular 70/7460-1 L Change 1, Obstruction Marking and Lighting, flags/red lights - Chapters 3(Marked),4,5(Red),&12. Any failure or malfunction that lasts more than thirty (30)minutes and affects a top light or flashing obstruction light, regardless of its position, should be reported immediately to (877) 487-6867 so a Notice to Airmen (NOTAM)can be issued. As soon as the normal operation is restored,notify the same number. As a condition to this determination,the temporary structure must be lowered to 104 feet above ground level ( 1036 feet above mean sea level) , when not in use and during the hours between sunset and sunrise. If the crane cannot be lowered to this height, then the following condition must also be met for nighttime conspicuity: The structure must be lighted in accordance with FAA Advisory Circular 70/7460-1 L Change 1, Obstruction Marking and Lighting, red lights—Chapters 4, 5(Red),&12. It is required that the FAA be notified 3 business days prior to the temporary structure being erected and again when the structure is removed from the site.Notification should be made to this office through your registered e-filing account.Notification is necessary so that aeronautical procedures can be temporarily modified to accommodate the structure.
