Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, & 702), Model CL-600-2D15 (Regional Jet Series 705), Model CL-600- 2D24 (Regional Jet Series 900), and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. This proposed AD was prompted by reports of corrosion found on the slat and flap torque tubes in the slat and flap control system. This proposed AD would require replacement of the slat and flap torque tubes in the slat and flap control system. We are proposing this AD to prevent rupture of a corroded slat or flap torque tube. This condition could result in an inoperative slat or flap system and consequent reduced controllability of the airplane.

The agency’s own summary, as published.
