Summary

We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-400 series airplanes. This proposed AD was prompted by reports of interruptions in the airstair door operation. This proposed AD would require repetitive inspections and modification of the handrail hardware. We are proposing this AD to address the unsafe condition on these products.
