Fiduciary Counselors, independent fiduciary for US Airways Group Inc.'s pension and retirement plans, will ask a federal bankruptcy court judge to require the airline to make its scheduled contributions to the plans despite being in Chapter 11 bankruptcy protection. The firm will ask the court to order the scheduled contributions to the airline's defined benefit plans for mechanics and flight attendants, and to defined contribution plans for pilots and other employees. The airline was required to contribute $154 million this year, but US Airways had contributed only $22 million of that in the first six months of this year. It also withheld $110.5 million in pension contributions due Sept. 15. Fiduciary Counselors will present its case to Judge Stephen S. Mitchell in U.S. Bankruptcy Court in Alexandria, Va., in a legal filing due Oct. 1, said Nell Hennessy, Fiduciary Counselors president. The firm also was the independent fiduciary to the Arlington, Va.-based airline's defined contribution plans when the company first filed for Chapter 11 bankruptcy in 2002.
