B206 door diagram
helipan: I've been in the front and back seats of early JetRangers a million times (well, a lot anyway) and I simply don't remember the 'D' shaped handles operating in the opposite sense between front and rear. I'll be visiting a operator later in October who have some early 206's and I'll look out for this. Amazing isn't it, you think you know an aircraft well (I've had it on my licenced for 34 years) and something like this comes up and stumps you.
Perhaps the best way to get a diagram will be to go through the MM or IPC and pick the best one/s. There will be a page which shows the decals associated with the handles, i.e. the 'arrows' for correct direction plus 'lock' and 'unlock'. They are in place aren't they? They do get ereased and this is the kind of thing (mandatory/safety markings) that surveyors and auditors like to pounce on. Good luck
