PILOT REPORTED ICE ON THE WINDSHIELD AND LANDED SHORT OF THE RWY. OTHER CIRCUMSTANCES ARE UNKNOWN. (.19) ON JANUARY 6, 1999, AT 1530 CENTRAL STANDARD TIME, A BEECH BE35, N740T, PILOTED BY A COMMERCIAL PILOT, RECEIVED SUBSTANTIAL DAMAGE ON IMPACT WITH TERRAIN DURING A HARD LANDING ON RUNWAY 36 (4,099 FT X 75 FT, CONCRETE/DRY) AT JOHNSON COUNTY AIRPORT NEAR OLATHE, KANSAS. VISUAL METEOROLOGICAL CONDITIONS PREVAILED AT THE TIME OF THE ACCIDENT. THE 14 CFR PART 91 PERSONAL FLIGHT WAS OPERATING ON AN INSTRUMENT FLIGHT PLAN. THE PILOT REPORTED NO INJURIES. THE FLIGHT DEPARTED COFFEY COUNTY AIRPORT NEAR BURLINGTON, KANSAS, AT 1456 AND WAS EN ROUTE TO JOHNSON COUNTY AIRPORT. THE PILOT REPORTED THAT HE HAD ICE ON THE WINDSHIELD AND WINGS WHICH WAS VISUALLY CONFIRMED BY A POST ACCIDENT WITNESS TO BE APPROXIMATELY 3/4 IN. THE PILOT ADDITIONALLY STATED THAT HIS APPROACH SPEED WAS 110 KNOTS AT THE RUNWAY. (.4) THE PILOT REPORTED THAT HE WAS CLEARED TO 4,000 FEET MSL AT HIS REQUEST. APPROXIMATELY 40 MILES SOUTHWEST OF JOHNSON COUNTY EXECUTIVE AIRPORT, OLATHE, KANSAS, THE PILOT NOTICED CLEAR ICE FORMING ON THE WINDSHIELD AND THE WING'S LEADING EDGE. HE ADDED THAT THE RIME ICE BUILD UP WAS THREE INCHES THICK. THE PILOT STATED THAT HE FLEW THE LOCALIZER 36 APPROACH AT 120 MPH AND AS HE CROSSED THE THRESHOLD OF RUNWAY 36, APPROXIMATELY 20 FEET ABOVE THE RUNWAY SURFACE, HE STARTED TO 'ROUND OUT AND THE AIRPLANE IMMEDIATELY STALLED AND HIT HARD'. THE AIRCRAFT CAME TO REST ON THE RIGHT SIDE APPROACH END OF RUNWAY 36 WHERE THE RIGHT MAIN AND NOSE LANDING GEAR WERE FOUND COLLAPSED. AT 1553, THE JOHNSON COUNTY EXECUTIVE AIRPORT AUTOMATED SURFACE OBSERVING SYSTEM RECORDED A SURFACE TEMPERATURE OF -2 DEGREES CELSIUS AND AN OVERCAST CLOUD LAYER AT 2,200 FEET MSL. ADVISORY CIRCULAR 00-6A, AVIATION WEATHER STATES, '...ALL CLOUDS AT SUBFREEZING TEMPERATURES HAVE ICING POTENTIAL. HOWEVER, DROP SIZE, DROP DISTRIBUTION, AND AERODYNAMIC EFFECTS OF THE AIRCRAFT INFLUENCE ICE FORMATION.' AC 00-6A ALSO STATES, '...IF YOUR AIRCRAFT IS NOT EQUIPPED WITH DEICING OR ANTI-ICING EQUIPMENT, AVOID AREAS OF ICING. WATER (CLOUDS OR PRECIPITATION) MUST BE VISIBLE AND OUTSIDE AIR TEMPERATURE MUST BE NEAR ZERO DEGREES CELSIUS OR COLDER FOR STRUCTURAL ICE TO FORM.' POST ACCIDENT EXAMINATION OF THE AIRCRAFT REVEALED 3/4-INCH THICK RIME ICE ONTHE AIRCRAFT'S WING AND EMPENNAGE LEADING EDGES. ## The NTSB's investigation of this event (1) From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. - [NTSB CHI99LA061](https://openairdocs.org/ntsb/CHI99LA061), Jan 6, 1999: Beech BE-V35B (N740T), Olathe, KS, substantial damage. Probable cause: The pilot's continued flight into adverse weather that resulted in structural icing and subsequently an aerodynamic stall on landing flare. A factor was the pilot's inadequate weather evaluation . From the FAA Accident/Incident Data System. 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/).
