Narrative:

There is a black crane approximately 300-400 ft AGL erected on the runway 17 centerline at 3o9 airport approximately 1;500 ft from threshold. The crane was not NOTAM'd and did not display flag in accordance with AC 150/5370-2. Evasive action in form of immediate go-around was initiated. I reported the obstruction to the flight data center; but was told no action could be taken as I was not associated with the operation of the crane or airport. 3o9 is unattended during winter months.
