After three accidents involving airplanes colliding with meteorological towers, the National Transportation Safety Board has recommended to the Federal Aviation Administration and three other agencies that the towers be marked for additional safety.
NTSB wants the FAA to require all towers to be registered, marked and lighted. The agency also proposed that the FAA create and maintain a publicly accessible data base for the required registration of the towers.
The safety agency proposes the Department of Interior, Department of Defense, and Department of Agriculture, as part of their review and approval of applications to build towers, to provide a copy of the obstruction marking and lighting advisory circulars.
The NTSB also proposes the American Wind Energy Association revise its handbook to clearly indicate the hazards that meteorological towers pose to low-altitude operations and encourage marking them to improve visibility.
Also, the NTSB proposes states, District of Columbia , Puerto Rico, Northern Marina Islands, and the territories of Samoa and Virgin Islands enact legislation requiring that meteorological towers be marked and registered in a directory.
