DOCKET 

MOTION OF TWIN CITIES AIR SERVICE, LLC 

TO WITHHOLD INFORMATION FROM PUBLIC DISCLOSURE 

Pursuant to section 302.12 of the Department's Rules of Practice, Twin Cities Air Service, 

LLC ("Twin Cities") hereby moves to withhold from public disclosure Exhibits TC-12 

through TC-14A-D. These documents are being filed with this Motion in a sealed 

envelope marked "Confidential Materials - Rule 12 Treatment Requested." In support of 

this Motion, Twin Cities submits the following: 

• Exhibit TC-12 is the Financial Statements and Supplementary Information 

for the Years Ended December 31, 2005 through December 31, 2009. 

• Exhibit TC-13 is Twin Cities' Forecast Balance Sheet. 

• Exhibit TC-I4 is Twin Cities' Capital Estimate and Description. 

• Exhibit TC-14A is a credit letter from Machias Savings Bank. 

• Exhibit TC-14B is a true and correct copy of Twin Cities' Commercial 

Loan Security Agreement with Northeast Trading Corporation ("Northeast 

Trading"). 

• Exhibit TC-14C is a true and correct copy of Twin Cities' Commercial 

Line of Credit Agreement and Promissory Note with Northeast Trading. 

• Exhibit TC-14D is a true and correct copy of the Guaranty in favor of 

Northeast Trading. 

The information Twin Cities seeks to withhold from public disclosure contains sensitive 

financial and commercial information, including financial information for activities other 
than the projected flights. Moreover, the information is highly detailed and would not 

otherwise be made accessible to persons outside the company. The release of this 

information would thus cause substantial harm to the competitive position of Twin Cities 

or the individual from whom the information was obtained. 

Therefore, Twin Cities respectftilly requests that this information be afforded confidential 

treatment by the Department under Rule 12. 

Submitted by.
