We propose to supersede Airworthiness Directive (AD) 2014-20- 09 for certain Bombardier, Inc. Model DHC-8-400 series airplanes. AD 2014-20-09 currently requires an inspection for missing clamps that are required to provide positive separation between the alternating current (AC) feeder cables and the hydraulic line of the landing gear alternate extension, and related investigative and corrective actions if necessary. Since we issued AD 2014-20-09, it was determined that certain airplane serial numbers are not subject to the identified unsafe condition. This proposed AD would remove airplanes from the AD applicability. We are proposing this AD to address the unsafe condition on these products.
