NTSB Safety Recommendation — Aviation
Recommendation text
TO THE FEDERAL AVIATION ADMINISTRATION: Conduct a survey of fuel quantity indication system probes and wires in Boeing 747s equipped with systems other than Honeywell series 1-3 probes and compensators and in other model airplanes that are used in title 14 Code of Federal Regulations Part 121 service to determine whether potential fuel tank ignition sources exist that are similar to those found in the Boeing 747. The survey should include removing wires from fuel probes and examining the wires for damage. Repair or replacement procedures for any damaged wires that are found should be developed.
