What the agency says
The FAA proposes to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 747-400, 747-400F, 747-8F, and 747-8 series airplanes. This proposed AD was prompted by a report that, during potable water servicing, there were multiple engine indicating and crew alerting system messages. The cause was the separation of a fitting and steel water supply tube above an electronics equipment cooling air filter, behind the forward cargo compartment left sidewall. This proposed AD would require, depending on configuration, installing at certain locations: conduits on exposed potable water supply lines, envelope assemblies over all exposed potable water line fittings and exposed potable water supply lines, a slitted spray shield, a 2-piece deflector shield around the equipment cooling system air inlet, and/or a shroud on exposed potable water supply lines. The FAA is proposing this AD to address the unsafe condition on these products.
