Mayor Dan Sullivan has withdrawn a proposal to increase annual registration fees for small aircraft, saying his administration needs to work on the issue further.

The plan was to double municipal fees for registering planes, from $75 to $150 for single-engine craft and from $125 to $250 for twin-engine planes.

That increase would have raised $210,000 more for the 2011 city budget.

But Sullivan said at tonight's Assembly meeting that city treasurer Dan Moore had raised an issue that needs to be addressed before the fees are raised. The problem is that the city applies different taxes and fees to different types of property, such as boats and aircraft, Sullivan said.

The mayor said he wants to meet with aircraft owners and others to re-do the proposal.
