NTSB Safety Recommendation — Aviation
Recommendation text
THE NTSB RECOMMENDS THAT THE FEDERAL AVIATION ADMINISTRATION: ISSUE AN AIRWORTHINESS DIRECTIVE (AD) REQUIRING AN IMMEDIATE FIELD INSPECTION OF ALL BEECH B200 AND OTHER KING AIR SERIES AIRPLANES WITH SIMILAR CROSS FLOW DRAIN HOLE CONSTRUCTION TO ENSURE THAT THE CROSS FLOW DRAIN HOLES CONFORM TO DIMENSIONS IN THE ENGINEERING DRAWING 50-440014. THE AD SHOULD INCLUDE MAINTENANCE INSTRUCTIONS FOR ENLARGING THE HOLE OR REMOVING EPOXY SEALER IN THOSE AIRPLANES THAT DO NOT CONFORM TO THE DIMENSIONS AND SHOULD CONTAIN REPORTING REQUIREMENTS TO THE FEDERAL AVIATION ADMINISTRATION TO ENSURE THAT ALL AIRPLANES ARE INSPECTED AND THAT THE SCOPE OF THE NONCONFORMITY IS DEFINED. (URGENT)
In plain language (FlightFinder summary)
The NTSB asks the FAA to issue an Airworthiness Directive requiring immediate field inspections of Beech B200 and similar King Air series airplanes to ensure cross flow drain holes match engineering drawing dimensions. The directive must include maintenance instructions for correcting nonconforming holes and require reporting to the FAA to confirm all airplanes are inspected and the extent of nonconformity is documented. The recommendation is marked urgent.
