(16) Master switch - OFF. d.  Landing With Nose Gear Unsafe.  If the landing gear control switch handle warning light is illuminated and the nose   GEAR   DOWN   indicator   light   shows   an   unsafe condition,  the  nose  gear  is  probably  not  locked  down, and  the  gear  position  should  be  checked  visually  by another  aircraft,  if  possible.    If  all  attempts  to  lock  the nose gear fail, a landing should be made with the main gear down and locked.  Hold the nose off the runway as long   as   possible   and   do   not   use   brakes.      Use   the following procedures: (1) Crew emergency briefing Complete.
