Posted on: 1996-04-19
Description
Some temperature sensitive triggers were not x-rayed.  These triggers could contain internal voids that would make the triggers susceptible to advanced creep causing false activation and venting of the cng.

Consequence
Venting of the cng could result in a fire.

Corrective Action
Neoplan will replace the prd with the newer design generation 2.5 pressure relief device.
