Accident Board Recommendations - continued

Additionally, the CAB made the following recommendations concerning the Boeing 727:

1. Fuel lines through the fuselage should be rerouted so that they pass through the floor beams near the centerline of the aircraft.
2. The fuel lines and their shrouds should be made of stainless steel and should have a wall thickness of sufficient dimension to withstand rather severe impacts. We suggest that the wall thickness be not less than 0.040 inch.
3. The generator leads should be routed so that there is maximum separation between these leads and the fuel lines. Each lead should be in a separate plastic conduit with suitable strength and flexibility to withstand bending and reasonably high tensile load.

Finally, the CAB also recommended that all other similarly configured aircraft (e.g., DC-9, Lear Jet, Caravelle, BAC 111, Jet Commander) be the subjects of a study to determine whether or not analogous dangers existed in their fuel and electrical system geometries.
