Applicability*9
This AD applies to De Havilland Aircraft of Canada Limited (Type Certificate previously held by Bombardier, Inc.) Model DHC-8-400, -401, and -402 airplanes, certificated in any category, having serial numbers 4001, 4003, and subsequent.
Compliance

Required actions
For the purposes of this AD, “prohibited tasks” are identified as any task identified in paragraph (j) of this AD and any procedure or task that specifies fuel tank access using non-manufacturer-approved procedures.
Unsafe condition
This AD was prompted by a report that electrical bonding jumpers had been installed on fuel scavenge lines even after the removal was required by previous AD rulemaking and electrical bonding jumpers may have been installed in production or in service at other locations. The FAA is issuing this AD to address altered electrical bonding paths, which may lead to lightning strike-induced ignition of the fuel tank.
Affected ADs
None.
