NARRATIVE: ON MARCH 11, 1998 AT 1552 HRS LOCAL, A BAE-146-200 OPERATED BY AIR WISCONSIN AIRLINES RAN OFF THE RUNWAY AT ASPEN, COLORADO. THE AIRCRAFT (N607AW) FLIGHT NUMBER 5661 ENROUTE DENVER TO ASPEN WAS LINED UP FOR A ROUTINE LANDING ON RUNWAY 33 IN ASPEN. UPON DESCENT JUST PRIOR TO TOUCHDOWN THE CREW RECEIVED A GREEN HYDRAULIC SYSTEM FAILURE LIGHT ON THE OVERHEAD PANEL. THEY HAD LOW PRESSURE AND VOLUME. THE CREW SWITCHED TO THE YELLOW ALTERNATE HYDRAULIC SYSTEM AND LANDED THE AIRCRAFT WITHIN THE NORMAL RUNWAY PERIMETERS AS WITNESSED BY THE ASPEN AIR TRAFFIC CONTROLLER (KAREN SHANNON). SHE OBSERVED DURING THE ROLL OUT AT ABOUT THE MIDWAY POINT A BLUE-WHITE SMOKE WAS EMERGING FROM THE TIRES AND CALLED THE EMERGENCY CREW TO RESPOND. MEANWHILE THE AIRCRAFT CREW WAS NOT RECEIVING THE CORRECT BRAKING RESPONSE FROM THE YELLOW SYSTEM AND THEY DECIDED TO UTILIZE THE EMERGENCY YELLOW HYDRAULIC SYSTEM. BOTH MAIN BRAKES LOCKED UP BECAUSE THE ANTI SKID SYSTEM DOES NOT FUNCTION WHILE ENGAGING THE EMERGENCY SYSTEM. THE LOCK UP OCCURRED MID WAY DOWN THE RUNWAY AT A5 RESULTING IN THE LEFT MAIN TIRES BLOWING AT THE A6 MARKER WITH THE RIGHT MAIN GEAR BLOWING AT THE A7 MARKER. WITH THE GREEN HYDRAULIC SYSTEM INOPERATIVE THE NOSE STEERING IS INCAPACITATED. THE BAE STARTED VEERING TO THE LEFT AFTER THE MAIN TIRES LOCKED UP AND AT MARKER A7 THE LEFT GEAR WITH TWO BLOWN TIRES TOOK OUT THE A7 MARKER SIGN WITH THE RIGHT GEAR TAKING OUT THE A8 SIGN. AT THE A8 MARKER THE AIRCRAFT WAS APPROACHING AN APPROXIMATELY 75 DEGREE ANGLE TO THE LEFT OF THE RUNWAY AND SLID ACROSS THE TAXIWAY A8 INTO THREE FEET OF SNOW AT THE END OF THE RUNWAY ABOUT 75 FEET AT A RIGHT ANGLE TO THE RUNWAY. ALL FOUR MAIN TIRES WERE BLOWN, THERE WAS HYDRAULIC FLUID LEAKING FROM THE LEFT MAIN WHEEL WELL AND THE NOSE WHEEL WELL. THERE WAS AN 8 BY TWO INCH GASH JUST AFT OF FORWARD BAGGAGE DOOR AND NUMBER TWO, THREE AND FOUR ENGINES HAD SIGNS OF INGESTION. THERE WAS NOT AN EMERGENCY EVACUATION, THE PASSENGERS WERE REMOVED BY THE REAR AIR STAIRS AND BUSSED TO THE TERMINAL. THERE WERE NO REPORTED INJURIES. THE FAILURE WAS DETERMINED TO BE A NOSE GEAR HYDRAULIC PRESSURE LINE, GREEN SYSTEM, HAD RUPTURED BETWEEN THE LINE AND THE CONNECTOR. NOTE: WHEN THE GREEN HYDRAULIC SYSTEM FAILS THE FOLLOWING PREVAILS: (1) LANDING GEAR......RETRACTION NOT AVAILABLE. (2) WHEELBRAKES........MUST SELECT YELLOW SYSTEM (3) FLAPS..............HALF SPEED OPERATION (4) LIFT SPOILERS......APPROX. 1/3 OPERATION (5) AIRBRAKES..........INOP (6) STANDBY GENERATOR..INOP ## Other reports on N607AW (5) Matched to the same aircraft by N-number and date. - [Incident 19920820037369I](https://openairdocs.org/incident/19920820037369I), Aug 20, 1992: Bag BAE146200A (N607AW), Chicago, IL.

Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/).
