NTSB Issues Six New Safety Recommendations

Move The Result Of Three Accidents Involving Airplanes Colliding With Meteorological Evaluation Towers

The NTSB has issued six broad-reaching safety recommendations after three accidents in which airplanes collided with Meteorological Evaluation Towers (METs). In each of the accidents, which occurred between 2005 and 2011, the MET was unmarked and unlighted. All resulted in fatal injuries. In the 2011 case, the permit for the MET had expired more than a year before the accident occurred, but it had not been removed as stipulated by its permit. The Board says that METs are often temporary structures, and at under 200 feet tall, are not required to be marked and lighted by the FAA.

The Board recommends that the FAA amend 14 Code of Federal Regulations Part 77 to require that all meteorological evaluation towers be registered, marked, and—where feasible—lighted, and that the agency create and maintain a publicly accessible national database for the required registration of all meteorological evaluation towers.

They further recommend that the American Wind Energy Association revise the Wind Energy Siting Handbook to clearly indicate the hazards that meteorological evaluation towers (MET) pose to low-altitude aviation operations and encourage voluntarily marking them to increase their visibility by reference to Advisory Circular70/7460-1, “Obstruction Marking and Lighting.” The association should also inform members about the circumstances of the airplane accidents that have occurred in connection with the presence of meteorological evaluation towers (MET) and emphasize the importance of understanding the aviation safety hazards associated with METs when erecting them.

The Board says that in the review and approval of applications processes for the construction of METs conducted by the United States Department of the Interior, the United States Department of Defense, and the United States Department of Agriculture, applicants should be provided a copy of, or directed  to Advisory Circular 70/7460-1, “Obstruction Marking and Lighting.”

Finally, the board urged 46 States, the District of Columbia, the commonwealths of Puerto Rico and the Northern Mariana Islands, and the territories of America Samoa and the U.S. Virgin Islands to pass legislation requiring that meteorological evaluation towers be marked and registered in a directory.
