Unsafe condition

This AD was prompted by a report of a smoke-in-cabin event due to a non-sustaining electrical fire. We are issuing this AD to prevent an electrical short of a bonding jumper wire that may result in in-flight smoke or fire events, as well as failure of avionics equipment, due to possible water spray or leakage from a damaged water supply line.

Affected ADs

None.
