Attachment (D) <br />FAA ORDER 8260.19© AIRSPACE OBSTRUCTION EVALUATION Discussion <br />GENERAL <br />14 CFR Part 77 requires that the Administrator be notified prior to the construction or <br />alteration of structures which might present a hazard to flight. Form 7460 -1, Notice of <br />Proposed Construction or Alteration, is the medium for that notification of construction <br />or alteration. <br />RESPONSIBILITY AND PROCESSING OF FAA FORM 7460 -1 <br />The regional ATD (Air Traffic Division) has the responsibility to process all Forms 7460- <br />1 in accordance with 14 CFR Part 77 and FAA Order 7400.2, PROCEDURES FOR <br />HANDLING AIRSPACE MATTERS. In this regard, AVN -100 (Aviation System <br />Standards Flight Procedures Branch) shall ensure that a complete evaluation of the <br />effect the proposed construction or alteration will have on IFR aircraft operations, <br />including the visual portion of an IFR procedure, is provided to Air Traffic. AVN - <br />100 shall also assist Air Traffic in reconciling possible discrepancies in IFR findings <br />made by military services. Additionally, the Regional Flight Standards Division (FSD), <br />All Weather Operations Program Manager, shall serve as the focal point for assessing <br />VFR operational impact. Initial impact assessments should be made by the Flight <br />Procedures Office (FPO) and FSD,t <br />TERMINAL AREA IFR OPERATIONS <br />AVN -100 shall assess the effect upon terminal area IFR operations to include <br />approach /departure procedures, transitions, radar vectoring charts, holding patterns, <br />and STARS. The study should assess the effect upon any segment of an existing or <br />proposed instrument approach /departure procedure and any restrictions. <br />If the proposed construction or alteration will have an adverse effect on VFR or IFR <br />aircraft operations, procedures, or minimum IFR flight altitudes, AVN -100 and Flight <br />Standards evaluations should clearly state the extent of these effects. Air Traffic is <br />responsible for making the final determination of whether adverse impacts are <br />substantial or minimal. <br />NOTE REGARDING FLIGHT INSPECTION AIRCRAFT AND OE ANALYSIS <br />Flight Inspection aircraft do not go to check out a building after it is built. Flight <br />Inspection aircraft perform initial and periodic inspections of all instrument procedures in <br />conjunction with the inspection of the supporting navigational aid. Flight Inspection <br />checks out new and revised instrument approach procedures prior to the procedures <br />' All references are made to selected portions of FAA Order 8260.19C that direct certain specific actions of the <br />different entities involved in the OE Evaluation Process. <br />14 <br />
