            Background: The FAA has received reports of crossed wiring and plumbing in the cargo compartment smoke detection system and engine fire extinguishing systems on Boeing aircraft of similar design.

Incorrectly installed fire detection and extinguishing systems could result in the failure to properly detect or extinguish a fire in the cargo compartment or in an engine.
