NTSB narrative

THE C-172, N49231, HAD JUST DEPARTED RWY 32 AT HARVEY FIELD, AN UNCONTROLLED AIRPORT, ON AN INSTRUMENT TRAINING FLIGHT. RADAR DATA SHOWS THAT THE C-172 WAS CLIMBING OUT AT 700-800 FPM AT 65 KTS AND ON A TRUE HEADING OF 310 DEG. THE BE-J35, N66QB, HAD DEPARTED EARLIER FROM PAYNE FIELD AT EVERETT. RADAR DATA SHOWS THAT THE BE-J35 WAS IN LEVEL FLIGHT AT 130 KTS AND ON A TRUE TRACK OF 280 DEG. THE COLLISION OCCURRED AT 1,600 FT MSL IN UNCONTROLLED AIRSPACE. THE CABIN TOP AND LEFT WING OF THE HIGH-WING C-172 DISPLAYED LINEAR SCRATCHES, GOUGES AND PAINT SMEARS WHICH MATCHED THE IMPACT DAMAGE, SCRATCHES AND GOUGES FOUND ON THE BOTTOM SURFACE OF THE LEFT WING OF THE LOW-WING BE-J35. OFFICIAL SUNSET WAS 1 MINUTE AFTER THE ACCIDENT; THE SUN WOULD HAVE BEEN 0.01 DEG ABOVE THE HORIZON AT THE COLLISION ALTITUDE, AND AT A TRUE BEARING OF 284.6 DEG FROM THE ACCIDENT SITE. WITNESSES REPORTED DUSK DARK LIGHT CONDITIONS ON THE GROUND.

Probable cause

THE FAILURE OF THE PILOT OF N66QB, A BEECH J35, TO SEE AND AVOID THIS AIRCRAFT. CONTRIBUTING FACTORS WERE: THE FLIGHT PATH OF THE OTHER AIRCRAFT DIRECTLY INTO THE SETTING SUN, AND THE LOW LIGHT CONDITIONS OF DUSK ON THE GROUND BELOW.

  • 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 1989-08-30.
  • API snapshot SHA-256: b335f783616535c2028189995ae4d29c5f45c8f47cb268c123c313ab1786ff47; retrieved 2026-09-21T03:10:32.711Z.
