     Curtis,
     
     You won't find all, if any, of the failed nylaflow incidents in the 
     NTSB reports.  Unless the incident meets the criteria for reporting 
     AND it was reported, you won't find anything.  
     I saw a Glasair undergoing repairs after a brake fire caused by a 
     burst nylaflow brake line.  An aborted takeoff from a short field with 
     the plane heavily loaded required very heavy braking.  After turning 
     off the runway the heat soaked brakes melted the nyla flow tubing 
     which then sprayed hydraulic fluid and led to the fire.  The plane 
     ended up in the mud off the taxiway because directional control was 
     lost.
     I feel more comfortable with aluminum hard lines and flexible 
     hydraulic hoses where needed.  They add a huge safety factor to the 
     system both in operation and in durability.
