NTSB narrative

THE AIRPLANE WAS ON AN ILS RUNWAY 15 APPROACH AND COLLIDED IN-FLIGHT WITH STATIC WIRES, APPROXIMATELY 2 MILES NORTH OF THE RUNWAY. THE WIRES WERE LOCATED IN THE AIRPLANE'S FLIGHT PATH, AND IN A DIRECT LINE WITH THE ILS FINAL APPROACH COURSE. AT THE TIME OF THE ACCIDENT THE LOCAL CONTROL TOWER WAS CLOSED. THREE OTHER AIRCRAFT MADE THE APPROACH PRIOR TO N402BK, AND THE PILOTS OF THOSE AIRCRAFT ALL AGREED THAT AT ABOUT 500 TO 700 FEET MSL, ON THE FINAL APPROACH COURSE, THEY ENCOUNTERED DOWNDRAFTS AND TURBULENCE. ALL THE PILOTS AGREED, THE DOWNDRAFTS CAUSED THEIR AIRPLANES TO FALL BELOW THE GLIDE SLOPE, AND THAT IN ORDER TO REJOIN THE GLIDE SLOPE, THEY HAD TO INCREASE POWER OR CHANGE THE AIRPLANE'S PITCH ATTITUDE. THE OTIS AIR NATIONAL GAURD BASE 2155 WEATHER OBSERVATION WAS; INDEFINITE CEILING 100 SKY OBSCURED, VISIBILITY 3/4 MILES, LIGHT RAIN AND FOG, TEMPERATURE 59 DEGREES F, DEW POINT 58 DEGREES F, WIND 170 DEGREES, 14 KNOTS, GUST TO 19, ALTIMETER 29.96 INCHES HG.

Probable cause

the pilot's failure to maintain a proper glide path during an ILS approach, which resulted in a collision with power lines. Factors in this accident were; adverse weather conditions with turbulence, down drafts and fog.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: local date, investigation status. Values present in the bulk record are kept.
  • The date is the local date; the NTSB stores the UTC date 1994-11-19.
