Response: THE BOARD NOTES THAT ASA HAS IMPLEMENTED POLICY CHANGES THAT TARGET A MAXIMUM OF SIX LANDINGS PER DAY, REDUCE MAXIMUM DAILY HOURS, LIMIT CONSECUTIVE OVERNIGHTS, & CONTROL THE ADDITIONAL FLIGHT HOURS THAT PILOTS MAY VOLUNTARILY ACQUIRE. WE ACKNOWLEDGE THAT THESE ACTIONS APPEAR TO BE POSITIVE STEPS TOWARD REDUCING POSSIBLE ADVERSE EFFECTS OF LONG DUTY DAYS & REDUCED REST PERIODS. HOWEVER, THE BOARD ALSO NOTES THAT ASA DISAGREES WITH THE BOARD'S INTERPRETATION OF THE INTENT OF 14 CFR PART 135 REST REQUIREMENTS. THE BOARD CONTINUES TO BELIEVE THAT THE PRIMARY USE OF REDUCED REST PERIODS SHOULD BE TO ACCOMMODATE UNFORESEEN OPERATIONAL DELAYS RESULTING FROM WEATHER, AIR TRAFFIC CONTROL, & MECHANICAL PROBLEMS, & THAT THE SCHEDULING OF REDUCED REST PERIODS SHOULD BE DONE ONLY INFREQUENTLY. MOREOVER, IN PUBLISHING THE FINAL RULE, THE FAA STATED THAT IT "EXPECTS THAT MOST AIR CARRIERS WILL SCHEDULE AT LEAST 9- TO 11-HOUR REQUIRED REST PERIODS." THEREFORE, WE CONTINUE TO BELIEVE THAT, NOTWITHSTANDING THE CITED ASA POLICY CHANGES, THE SCHEDULING OF APPROXIMATELY 60 PERCENT OF YOUR DAY-TO-DAY LAYOVERS AS REDUCED REST PERIODS IS NEITHER CONSISTENT WITH THE INTENT OF THE REDUCED REST PROVISION OF 14 CFR PART 135 NOR IN THE INTEREST OF AVIATION SAFETY. ACCORDINGLY, THE BOARD CLASSIFIES RECOMMENDATION A-92-29 AS "CLOSED--UNACCEPTABLE ACTION."

Response: ASA HAS ALWAYS OPERATED WITHIN THE INTENT OF FAA CREW REST REQUIREMENTS. IN CAREFUL READINGS OF THE MATERIAL THE FAA PUBLISHED WITH THE FLIGHT TIME LIMITATIONS AND REST REQUIREMENTS IN 1985, WE FIND NO INFERENCE OR STATEMENT OF INTENT THAT REDUCED REST PERIODS SHOULD NOT BE SCHEDULED. IN FACT, A FULL READING OF THE FIRST PARAGRAPH QUOTED ON PAGE TWO OF YOUR LETTER CLEARLY STATES THAT SCHEDULING FLEXIBILITY IS ONE OF THE PURPOSES OF THE REST REDUCTION ALLOWED UNDER THE NEW RULES. WE FEEL WE MUST, THEREFORE, DISAGREE WTIH THE INTERPRETATION OF 14 CFR PART 135 REST REQUIREMENTS CONTAINED IN A-92-29. FURTHERMORE WE ARE DISAPPOINTED THAT THIS "NON-CAUSE" WAS INAPPROPRIATELY INCLUDED IN THE RECOMMENDATIONS ASSOCIATED WITH FLIGHT 2311. ASA SHARES THE NTSB'S CONCERN FOR APPROPRIATE CREW REST AND CONSTANTLY SEEKS TO ACHIEVE A BALANCE BETWEEN CREW TIME OFF AND PRODUCTIVITY. MONTHS AGO WE IMPROVED ON SCHEDULED REST AND DUTY TIME BY INSTITUTING MAXIMUM DAILY HOURS (PRESENTLY, OVER AVERAGE IS APPROXIMATELY FIVE SCHEDULED BLOCK HOURS PER DUTY DAY), LIMITED CONSECUTIVE OVERNIGHTS, AND CONTROLLED THE ADDITIONAL FLIGHT HOURS WHICH PILOTS MAY VOLUNTARILY ACQUIRE. WE WILL ALSO BE PROVIDING INPUT TO THE REGIONAL AIRLINE ASSOCIATION FOR USE IN THE FAA AVIATION RULEMAKING ADVISORY COMMITEE'S UPCOMING STUDY OF FLIGHT CREW DUTY TIME ISSUES.
