Congress recently passed HR 636 FAA Extension, Safety & Security Act which serves as a one-year budget extension for the FAA and contains several directives that must be addressed over the next year. One such directive is to change the rules of tower marking for towers shorter than 200’ AGL. The FAA has one year to incorporate the details of implementation into the advisory circular.
Essentially, any tower between 50’ and 200’ above ground level (AGL) that is less than 10’ in diameter at the base may be subject to lighting per AC 70/7460-1L, with some exceptions. It doesn’t appear there is anything you need to do right now other than be familiar with the lighting rules below 200’ and be prepared for what may be deemed a “covered tower” when the AC is updated next year.
Please contact us if you have any questions and we will do our best to answer them with the information we have at this time.
