Action
Notice of proposed rulemaking (NPRM).
Summary
The FAA proposes to amend the regulations governing objects that may affect the navigable airspace. Specifically, the FAA is proposing to add notification requirements and obstruction standards for electromagnetic interference and amend the obstruction standards for civil airport imaginary surfaces to more closely align these standards with FAA airport design and instrument approach procedure criteria. The FAA proposes to require proponents to file with the agency a notice of proposed construction or alteration of structures near private use airports that have an FAA approved instrument approach procedure. This proposal, if adopted, would also increase the number of days in which a notice must be filed with the FAA before beginning construction or alteration; add and amend definitions for terms commonly used during the aeronautical evaluation process; and remove the provisions for public hearings and antenna farms. Lastly, the FAA proposes to retitle the rule and reformat it into sections that closely reflect the aeronautical study process. These proposals incorporate case law and legislative action, and simplify the rule language. The intended effect of these proposed changes is to improve safety and promote the efficient use of the National Airspace System.
