Synopsis: ON OCTOBER 28, 1973, A PIEDMONT AIRLINES BOEING 737-222, OVERRAN THE DEPARTURE END OF RUNWAY 14 ON THE GREENSBORO-HIGH POINT-WINSTON- SALEM REGIONAL AIRPORT, IN GREENSBORO, NORTH CAROLINA. FIVE PERSONS WERE INJURED, AND THE AIRCRAFT WAS DAMAGED SUBSTANTIALLY.

Safety Recommendation History
From: NTSB
To: FAA
Date: 8/24/1983
Response: In your response to this safety recommendation, you state that you do not agree with the board's belief that information and techniques concerning hydroplaning phenomena should be incorporated in airplanes flight manuals, because you believe that the best means to disseminate information regarding the phenomena is through an ac and air carrier operations bulletins (acob). The safety board is aware of ac 91- 24, acob 7-76-32 and acob 7-76-33, and we believe them to be excellent documents. However, the board continues to believe that the recommended action has merit because the pilot has more ready access to afm, operations manuals, or pilot handbooks than he has to acs or acobs. Accordingly, because the safety board has no additional data to provide to the faa is support of the recommendation, safety recommendation a-74-125has been classified as closed--unacceptable action.

Response: FAA LETTER: WE DO NOT AGREE WITH THE BOARD'S RECOMMENDATION TO INCORPORATE INFORMATION AND TECHNIQUES CONCERNING HYDROPLANING PHENOMENA IN AIRPLANE FLIGHT MANUALS (AFM). THE TECHNIQUES FOR COPING WITH HYDROPLANING ENCOUNTERS DO NOT VARY SIGNIFICANTLY AMONG CURRENT AIR CARRIER AIRPLANES. THEREFORE, WE BELIEVE THE BEST MEANS TO DISSEMINATE INFORMATION AND TECHNIQUES REGARDING THE PHENOMENA IS THROUGH AN ADVISORY CIRCULAR (AC) AND AIR CARRIER OPERATION BULLETIN (ACOB). INFORMATON ON THE SUBJECT HAS BEEN GIVEN WIDE DISSEMINATION IN AC 91-24, "AIRCRAFT HYDROPLANING OR AQUAPLANING ON WET RUNWAYS," DATED SEPTEMBER 4, 1969. WE HAVE ALSO REVIEWED ACOB NOS. 7-75-32 AND 7-76-33, THAT ARE CURRENTLY EFFECTIVE. WE BELIEVE THESE ACOB'S ARE ADEQUATE IN PROVIDING ESSENTIAL INFORMATION AND RECOMMENDED TECHNIQUES FOR PILOTS, AS WELL AS ASSISTING RESPONSIBLE FAA INSPECTORS IN ASSESSING THE ADEQUACY OF AIR CARRIER PILOT TRAINING PROGRAMS AND COMPANY OPERATING INSTRUCTIONS REGARDING THE PHENOMENA. AIR CARRIER OPERATIONS BULLETIN NO. 7-76-32 REEMPHASIZES THE INFORMATION IN AC 91-24 FOR AIR CARRIER INSPECTORS, AND ACOB NO. 7-76-33 SETS FORTH SUGGESTED PROCEDURES FOR LANDING ON SLIPPERY RUNWAYS. ADDITIONALLY, THE FAA PLANS TO ISSUE A GENERAL AVIATION OPERATIONS BULLETIN (GAOB) BY OCTOBER 1983. THIS GAOB WILL SET FORTH SUGGESTED PROCEDURES ALONG THE LINES OF ACOB NO. 7-76-33, BUT ORIENTED TO GENERAL AVIATION OPERATIONAL REQUIREMENTS.

From: NTSB
To: FAA
Date: 4/11/1983
Response: Notwithstanding oru acceptance of runway grooving and ppc treatment as the best way to minimize hydroplaning, we do believe that flight manuals should contain information on the hydroplaning phenomena and techniques to be used in hydroplaning encounters. We, therefore, once again request the faa to reconsider this recommendation which we are maintaining in an open-unacceptable action status.

From: FAA
To: NTSB
Date: 6/7/1982
Response: Our experience has shown that the probability for hydroplaning is significantly reduced on runways treated by grooving or porus friction course (pfc) treatment. This fact was attested to by participants at the ntsb runway friction hearings held in washington, d.C. During the week of may 3, 1982. As of april 6, 1982, for airports served by air carriers, 274 runways have been grooved and 92 have received pfc treatment. Our goal is to treat, as rapidly as possible, all remaining air carrier airports subject to weather conditions casing low friction conditions. We believe minimizing hydroplaning conditions to be the preferred course of action, rather than promulgating regulations and limitations which are intended for operations in hydroplaning conditions. We believe the above action provides theincreased safety intended and consider action completed.

From: NTSB
To: FAA
Date: 3/22/1982
Response: These recommendations have been the subject of discussion between the faa and ntsb at several staff meetings. At the ntsb/faa quarterly meeting held on february 12, 1981, it was agreed that the faa would provide the safety board with a summary of actions taken with regard to these recommendations. We have not yet received the summary. We are aware of the faa's ongoing programs regarding the testing and maintenance of pave runway surfaces. However, we would appreciate being informed of the faa's proposed actions with regard to the resolution of these recommendations.

From: FAA
To: NTSB
Date: 5/31/1978
Response: FAA LTR: SINCE THE TRAIL APPLICATION PROGRAMS DESCRIBED IN OUR LETTER OF 1/14/75 DID NOT PRODUCE DATA SATISFACTORY FOR APPLICATION, WE DO NOT INTEND TO AMEND THE FLIGHT MANUALS AT THIS TIME.

From: FAA
To: NTSB
Date: 6/6/1975
Response: FAA LTR: BECAUSE THE PROBLEM IS GENERAL, WE DO NOT BELIEVE IT SHOULD BE INCLUDED IN ALL AIRPLANE FLIGHT MANUALS. THE SUBJECT IS PRESENTLY DISCUSSED IN ADVISORY CIRCULAR 91-24 (9/4/69), AND MORE SPECIFIC PROCEDURAL INFORMATION IS PROVIDED IN OPERATIONS MANUALS AND BULLETINS APPROPRIATE TO EACH CARRIER'S AIRCRAFT MODELS. WHEN SPECIFIC HYDRO PLANING DATA ARE OBTAINED ON INDIVIDUAL AIRCRAFT TYPES UNDER WET RUNWAY CONDITIONS, THEY WILL BE CONSIDERED FOR INCLUSION IN THE AIRPLANE FLIGHT MANUAL.

From: FAA
To: NTSB
Date: 1/14/1975
Response: FAA LTR: SINCE HYDROPLANING PHENOMENA IS A GENERAL PROBLEM, THE FAA DOES NOT CONSIDER IT A PROPER TOPIC FOR THE AIRPLANE FLIGHT MANUAL. IT IS PRESENTLY COVERED IN ADVISORY CIRCULARS AVAILABLE TO ALL PILOTS, IN SCHEDULED AIR CARRIER OPERATIONS MANUALS AND OPERATIONS BULLETINS. THE FLIGHT MANUAL SHOULD CONTAIN UNIQUE INFORMATION PERTINENT TO AIRCRAFT LIMITATIONS OPERATING PROCEDURES AND PERFORMANCE. THE FAA WILL CONSIDER SUCH SPECIFIC INFORMATION FOR INCLUSION IN FLIGHT MANUALS WHEN DEFINITIVE DATA IS OBTAINED FOR INDIVIDUAL AIRCRAFT.
