Subject: Response to Determination of No Hazard to Air Navigation
Dear Ms. Burch;
The State of Montana currently has no laws or regulations enforceable by the
State concerning aeronautical obstruction standards regarding height, however,
there are several state laws that allow and compel local airports, if affected, to
review and take action regarding height limitations for airport obstructions and
hazards as defined within Montana Code Annotated.
In addition to the above statement, I have reviewed Aeronautical study :
2010-ANM-45-OE and would like to make the following comments of concern
that could affect safe air navigation in Montana.
We recommend the proposed Antenna tower at a height of 172' AGL to be
located approximately 3 miles W. of Kalispell City airfield, be marked and
lighted in accordance with FAA Advisory Circular 70/7460-1 AC70/7460-
1 K. (Obstruction Marking and Lighting, red lights)
The Kalispell City airport elevation is 2932' MSL, the elevation of the
highest site and Antenna tower is 3872' MSL making the Antenna tower
request 940' above the Kalispell City airport elevation.
Please feel free to contact us if you have any other questions or would like any
additional information,
Sincerely,
Max Murphy, Aviation Support Officer
