Letters Warning MET Entities About Liability for Not Marking Towers

In another move to ensure proper marking of towers under 200 feet, NAAA has sent letters to the American Wind Energy Association and dozens of U.S. meteorological evaluation tower (MET) manufacturers warning them that ignoring an FAA Advisory Circular (AC) providing guidance on the marking of METs and other government warnings on the risks posed by unmarked METs would very likely result in legal liability for a tower company whose tower resulted in an accident due to improper marking. 

Let's Be Fair About Sharing The Air

The airspace aerial applicators work in is becoming increasingly obstructed by transmission lines, wind turbines and hard-to-see meteorological testing towers. That concerns the aerial application industry, not just in terms of safety, but also in terms of accessing farmers’ fields to treat their crops. In response, NAAA has launched a public outreach campaign to raise awareness about the worrisome effects of wind energy development on agriculture and aviation.

NTSB MET Safety Recommendations

The National Transportation Safety Board has issued six safety recommendations regarding Meteorological Evaluation Towers (METs) in the wake of investigations into three fatal aircraft collisions that resulted in four deaths. The recommendations were issued May 15, 2013, and are directed to the Federal Aviation Administration, the American Wind Energy Association, the U.S. Department of the Interior, the U.S. Department of Defense, the U.S. Department of Agriculture and the 46 states, four territories and District of Columbia without MET legislation.

FAA Releases Guidance on Marking MET Towers

The Federal Aviation Administration (FAA) has released the long-awaited guidance for marking MET towers less than 200 feet above ground level (AGL) in remote and rural areas. NAAA is very pleased to report that the comments provided by members and the Association have yielded guidance favorable to agricultural aviation. The FAA agrees that marking these structures would enhance the conspicuity of these METs, particularly for low-level agricultural operations.”

NAAA's Wind Tower Outreach Campaign Offers Tools to Inform Stakeholders of  the Risks to Ag Pilots and Farmers 

The prospect of converting high winds into big dollars is an enticing proposition for landowners, but one that can have far-reaching consequences for farmers and aerial applicators without careful planning. To ensure that farmers are fully informed before making decisions about wind energy development, NAAA encourages members to participate in our Wind Tower Education Campaign.

NATA MET Marking Guidance and Videos

Aviation Safety Videos Highlight Dangers of Unmarked Towers

The University of Nebraska Lincoln Extension program and the Nebraska Aviation Trades Association (NATA) recently produced two exceptional videos highlighting the dangers of unmarked METs and the necessity of proper tower marking for aviation safety. Both YouTube videos feature NATA and NAAA member Brian Wilcox flying near an unmarked tower.

Landowners are being asked to make crucial decisions that will impact farmers and their neighbors for years to come. It’s up to everybody in the industry—NAAA, its state association partners and aerial applicators—to educate the public about the consequences that ill-planned wind energy development can have on agriculture and aviation.
