Airworthiness Directives; Bombardier Model CL-215-1A10 (Water Bomber), CL-215-6B11 (CL215T Variant), and CL-215-6B11 (CL415 Variant) Series Airplanes

The FAA proposes to supersede an existing airworthiness directive (AD) that applies to certain Bombardier Model CL-215-1A10 (Water Bomber), CL-215-6B11 (CL215T Variant), and CL-215-6B11 (CL415 Variant) series airplanes. The existing AD currently requires repetitive ultrasonic inspections to detect cracking of the lower caps of the wing front spar and rear spar, and corrective action if necessary. This proposed AD would reduce the threshold to do the initial inspections and revise the repetitive inspection interval. This proposed AD also adds a repetitive ultrasonic inspection of the wing lower skin. This proposed AD is prompted by reports of cracks in the front and rear spar lower caps. We are proposing this AD to detect and correct cracking of the lower caps of the wing front spar and rear spar, which could result in reduced structural integrity of the airplane.
