I have a copy of FAA Notice N8400-61 which deals with reinforced cockpit door for Cargo Aircraft.
I cannot find the equivalent document for JAR.
Does anyone have any info on the actual JAR requirement for Cargo aircraft.
The FAA one basically says you can either fit the reinforced door or have security procedure in place agreed with the TSA.
My initial info is that it is not a hard JAR requirement but is an NCAA requirement.
