Summary

We propose to supersede Airworthiness Directive (AD) 2016-13- 14, for certain Bombardier, Inc., Model DHC-8-400 series airplanes. AD 2016-13-14 requires an inspection to determine if certain left and right main landing gear (MLG) retract actuator rod ends are installed and repetitive liquid penetrant inspections (LPIs) of affected left and right MLG retract actuator rod ends, and corrective actions if necessary. Since we issued AD 2016-13-14, we have determined that replacement of the left and right MLG is necessary to address the unsafe condition. This proposed AD would retain the actions specified in AD 2016-13-14 and add a replacement of the left and right MLG retract actuator rod ends. We are proposing this AD to address the unsafe condition on these products.

The agency’s own summary, as published.
