NOTE 1. Current weight and balance report, including list of e quipment included in certificated weight empty, and loading 
instructions when necessary, must be in each helicopter at the time of original certification and at all times thereafter.  
In order to obtain the most consistent weight and balance results, all model helicopters should be weighed on jack-
points rather than on wheels or floats.  The applicable Bell Maintenance and Overhaul Instructions contain complete 
information on this subject.
