AIRLINE SAFETY DEPARTMENTS & PILOT LABOR ORGANIZATIONS, SUCH AS THE ALLIED PILOTS ASSOCIATION & THE AIR LINE PILOTS ASSOCIATION, SHOULD BE CONSULTED AS PART OF THIS REVIEW. WE APPRECIATE THAT THE FAA PROVIDED US WITH A COPY OF THE BIENNIAL REVIEW PROCESS & HAS NOTIFIED THE BOARD OF THE IMPLEMENTATION OF THE APPROPRIATE PROCEDURES AS REQUESTED IN OUR LETTER OF 9/8/97.

To: NTSB
Date: 12/30/1997
Response: AS STATED IN OUR LETTER DATED 6/11/97, THE FAA ESTABLISHED A MANDATORY REVIEW FOR SIGNIFICANT TERRAIN FEATURES AS PART OF ITS BIENNIAL REVIEW PROCESS. FAA ORDER 8260.19C, FLIGHT PROCEDURES & AIRSPACE, SECTION 8, INCLUDES PROCEDURES FOR PERIODIC REVIEWS OF INSTRUMENT PROCEDURES. THESE REVIEWS ARE CONDUCTED EVERY 2 YEARS OR MORE FREQUENTLY WHEN DEEMED NECESSARY. THE REVIEWS ARE CONDUCTED IN ACCORDANCE WITH FAA ORDER 8260.3B. TERMINAL INSTRUMENT PROCEDURES (TERP), CHAPTER 3, TAKEOFF & LANDING MINIMUMS. PARAGRAPH 323A. PRECIPITOUS TERRAIN, WHICH STATES: "WHEN PROCEDURES ARE DESIGNED FOR USE IN AREAS CHARACTERIZED BY PRECIPITOUS TERRAIN, IN OR OUTSIDE OF DESIGNATED MOUNTAINOUS AREA, CONSIDERATION MUST BE GIVEN TO INDUCED ALTIMETER ERRORS & PILOT CONTROL PROBLEMS WHICH RESULT WHEN WINDS OF 20 KNOTS OR MORE MOVE OVER SUCH TERRAIN. WHERE THESE CONDITIONS ARE KNOWN TO EXIST, REQUIRED OBSTACLE CLEARANCE IN THE FINAL APPROACH SEGMENT SHOULD BE INCREASED. ORDER 8260.19C STATES THAT USER COMMENTS SHOULD BE SOLICITED TO OBTAIN THE BEST AVAILABLE LOCAL INFO TO ENSURE THAT REQUIREMENTS FOR OBSTACLE CLEARANCE, NAVIGATIONAL GUIDANCE, SAFETY, & PRACTICALITY ARE MET. ON 6/2/97, THE FAA REEMPHASIZED THE PROCEUDRES TO BE FOLLOWED WHEN CONDUCTING A PERIODIC REVIEW OF AN INSTRUMENT PROCEDURE. THE PROCEDURES REQUIRE THAT OBSTACLE, INCLUDING TERRAIN, BE CONSIDERED AS POTENTIAL PRECIPITIOUS TERRAIN WHEN DEVELOPING OR AMENDING A STANDARD INSTRUMENT APPROACH PROCEDURE & THAT THESE OBSTACLES ARE EVALUATED & APPROPRIATE ADJUSTMENTS MADE ACCORDING TO EXISTING FAA ORDERS & GUIDELINES. THE PROCEDURES ALSO REQUIRE THAT DISCUSSION & COORDINATION WITH THE USERS, AIRLINE SAFETY DEPARTMENT, & PILOT LABOR ORGANIZATIONS REMAIN AS A PART OF THE REVIEW PROCESS.
