NTSB Issues Recommendation Regarding Electrical Current and Flight Instrument Failures
The National Transportation Safety Board has directed the Federal Aviation Administration to investigate specific electrical anomalies affecting cockpit systems.
The National Transportation Safety Board has issued a formal recommendation, designated as A-94-136 under item number 79941. This directive requires the Federal Aviation Administration to work in coordination with McDonnell Douglas. The primary objective is to determine the source of the high electrical current that damaged the emergency power switch. Additionally, the investigation must identify the reason for the sporadic failure of the captain's flight instruments after the application of the electrical smoke in cockpit checklist. This action underscores the need for precise technical analysis regarding these specific system failures.
