## Summary

We propose to supersede Airworthiness Directive (AD) 2014-06- 08, for certain Bombardier, Inc. Model DHC-8-100, -200, and -300 series airplanes. AD 2014-06-08 currently requires repetitive functional checks of the nose and main landing gear, and corrective actions if necessary; and also provides optional terminating action modification for the repetitive functional checks. Since we issued AD 2014-06-08, we have determined that the optional terminating action modification is necessary to address the identified unsafe condition. This proposed AD would also require the terminating action modification. We are proposing this AD to detect and correct a false down-and-locked landing gear indication, which, on landing, could result in possible collapse of the landing gear.
