In late 2007, we signed a seven-year follow-on contract with Boeing for the production of fixed wing trailing edge assemblies for the Boeing 777 and 767 aircraft. During 2011, on average we delivered 7 ship sets per month on the Boeing 777 platform and 2 ship sets per month on the Boeing 767. For 2012, we currently estimate deliveries on these programs to be consistent with 2011. This multiyear contract has a potential value in excess of $100 million; however, annual quantities will vary, as they are dependent upon the orders Boeing receives from its customers.
Our U.K. Composites operations provide composite components for many Airbus platforms. The most significant of these are the A320, A330 and A340. Orders for these components are dependent on the customer's build rate.
Our bearings products are included on commercial airliners and regional / business jets manufactured in North and South America, Europe and Asia and are used as original equipment and/or specified as replacement parts by airlines and aircraft manufacturers. These products are primarily proprietary self-lubricating, ball and roller bearings for aircraft flight controls, turbine engines, and landing gear, and driveline couplings for helicopters. The most significant portion of our commercial sales is derived from Boeing and Airbus platforms, such as the Boeing 737, 747, 777 and 787 and the Airbus A320, A330, A350 and A380.
In September 2009, we were awarded a five-year contract with a potential value of $53 million to build composite helicopter blade skins and skin core assemblies for Bell Helicopter. Under the terms of the contract, we will provide 18 different assemblies for H1, 406, 407, 412, 427, 429, 430 and BA609 aircraft. All work is being performed at our full-service aerospace innovation and manufacturing support center in Bloomfield, Connecticut. First article deliveries to Bell's Hurst, Texas facility began in late 2009, with full production starting in the first quarter of 2010. Through December 31, 2011, the total sales value for our deliveries totaled $15.4 million. Annual quantities for this program will vary, as they are dependent upon the orders Bell receives from its customers.
We continue to work with potential customers for the sale of 11 SH-2G(I) aircraft, spare parts and equipment. Several foreign governments have expressed various levels of interest in the aircraft and we have received small orders for the spare parts and related equipment.
On December 21, 2011, we entered into an agreement with the U.S. Government ("USG") to settle lawsuits related to our prior FMU-143 fuze program. The terms of the settlement with the U.S. Government required us to make a $4.75 million payment, which was made in January 2012. In addition, both parties have released each other as to the subject matter of the litigation, the USG has withdrawn its fraud allegation and neither party has admitted liability. Separately, we wrote-off program related inventory in the amount of $1.45 million, net of reserves, bringing the total pre-tax impact of the settlement to $6.2 million.
