ATR and Bombardier will each soon receive requests for proposals to renew US Airways Express operator Piedmont Airlines' fleet. During last week's Regional Airline Association conference and exhibition in Memphis, Tennessee, US Airways Express president Robert Martens said the RFP will cover a mix of new 50- and 70-seat turboprops. These will replace Piedmont's ageing Bombardier Dash 8 fleet.
