NTSB Issues Safety Recommendation for Ice Observation Lights on Two-Pilot Aircraft

The National Transportation Safety Board has issued a safety recommendation directed at the Federal Aviation Administration. This recommendation, identified by the reference number A-94-117 and associated with investigation DCA94MA022, calls for specific regulatory changes to enhance aviation safety standards. The board advises that the applicable operating rules be amended to address equipment requirements for certain aircraft configurations. Specifically, the recommendation targets airplanes certified for two-pilot operation. The proposed amendment would require these aircraft to be configured with ice observation lights that illuminate both wings. This action is intended to improve visibility and situational awareness during flight operations in conditions where ice accumulation is a concern. The current regulatory framework under Part 23.1419, Section D, does not currently mandate this specific configuration for all two-pilot certified airplanes. By implementing this change, the board aims to ensure that pilots have adequate visual information regarding wing surfaces. This recommendation supersedes an earlier safety recommendation designated as A-92-065, indicating a continued focus on this particular safety issue over time. The Federal Aviation Administration is now tasked with reviewing and potentially adopting these changes to the federal regulations governing aircraft certification and equipment standards.
