Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 440), CL-600-2C10 (Regional Jet Series 700, 701 & 702), CL-600-2D15 (Regional Jet Series 705), CL-600-2D24 (Regional Jet Series 900), and CL-600-2E25 (Regional Jet Series 1000) airplanes. This AD was prompted by reports of power control unit (PCU) rod end fractures due to pitting corrosion. This AD requires revising the existing maintenance or inspection program, as applicable, to incorporate new maintenance tasks. This AD also requires detailed inspections of the elevator PCU rod ends and applicable corrective actions. This AD also prohibits using certain aircraft maintenance manual tasks. The FAA is issuing this AD to address the unsafe condition on these products.
