NTSB narrative

TWO 747S WERE ON APPROACH FOR RWY 31R, FOLLOWED BY A SWEARINGEN SA 227AC MERLIN. THE MERLIN WAS GIVEN A VISUAL APPROACH WHICH THE PILOT ACCEPTED AND TRAFFIC HE WAS TO FOLLOW WAS CALLED AS BEING AT THE 11 O'CLOCK POSITION. RADAR DATA SHOWED THE FIRST 747 ONLY 10 DEGREES TO THE LEFT OF THE NOSE OF THE MERLIN WHICH THE FLIGHT CREW IDENTIFIED AS THE TRAFFIC TO FOLLOW. THE SECOND 747 WHICH WAS THE ONE TO BE FOLLOWED WAS 45 DEGREES TO THE LEFT OF THE NOSE. THE MERLIN PASSED APPROXIMATELY 300 FT OVER THE TOP OF THE 2ND 747 IN THE VICINITY OF THE OUTER MARKER WHILE ON THE VISUAL APPROACH. NO EVASIVE ACTION WAS TAKEN. THE CAPTAIN OF THE MERLIN SAID HE NORMALLY FLYS 1 TO 1 1/2 DOTS HIGH ON THE GLIDE SLOPE FOR WAKE TURBULENCE. THE SUN WAS AT AN ANGLE THAT BACKLIGHTED BOTH 747S.

Probable cause

THE FAILURE OF THE SWEARINGEN FLIGHT CREW TO PROPERLY IDENTIFY THE AIRPLANE THEY WERE TO FOLLOW, PRIOR TO ACCEPTING THE VISUAL APPROACH TO RUNWAY 31R.

  • 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: investigation status, damage. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
  • API snapshot SHA-256: 5b06973ceddd91ee981a446d7795ae1fa385e9911492f40fd0bc9c58ce524c91; retrieved 2026-09-18T19:12:25.873Z.
  • The NTSB's operator name is blank for N305TW; the operator shown is the name the NTSB's other records give its FAA operator code, TWAA.
