Response: (SUMMARIZED) ON 12/19/90, MEMBERS OF THE FAA MET WITH MEMBERS OF THE SAFETY BOARD TO OBTAIN A CLARIFICATION OF THE INTENT OF THESE TWO SAFETY RECOMMENDATIONS. BASED ON THIS CLARIFICATION, THE FAA'S AIRPORT CERTIFICATION INSPECTORS WILL MAKE AIRPORT AND AIRCRAFT RESCUE AND FIREFIGHTING MANAGEMENT MORE AWARE OF TERRAIN, CROP, WEATHER, OR OTHER SITE-SPECIFIC CONDITIONS ON THE AIRFIELD AND THEIR EFFECT ON RESPONSE CAPABILITIES DURING THE ANNUAL INSPECTION AND/OR DURING THE REVIEW OF AN AIRPORT'S EMERGENCY PLAN. THE AIR PORT CERTIFICATION INSPECTORS WILL ENSURE THAT THE PLAN NOT ONLY ADDRESSES THE RUNWAY/TAXIWAY AREAS, BUT ALSO ADDRESSES THE WHOLE AIRPORT ENVIRONMENT TO INCLUDE PROCEDURES FOR TRAVERSING ALL AREAS OF THE AIRPORT AND ADDRESSES SURFACE OBSTACLES SUCH AS CROPS WHICH MAY INTERFERE WITH RESCUE AND FIREFIGHTING ACTIVITIES.
