NTSB narrative
THE PLT OF A WACO UPF-7, N32133, RPRTD HE WAS TAXIING WITH S-TURNS BEHIND A CESSNA 172, N6552F, ON A DIAGONAL TWY. AS THE CESSNA PLT APCHD THE INTERSECTION WITH THE PARALLEL TWY TO THE ACTIVE RWY (RWY 9), HE ELECTED TO STOP & GIVE WAY TO A COMMERCIAL AIRLINER. THE WACO PLT CONTD TAXIING & DID NOT NOTICE THAT THE CESSNA HAD STOPPED UNTIL HIS ACFT WAS ABOUT 20 TO 30 FT FROM THE CESSNA. THE WACO PLT APPLIED BRAKES, BUT WAS UNABLE TO STOP BEFORE THE PROP OF HIS ACFT HIT THE EMPENNAGE OF THE CESSNA 172.
Probable cause
INADEQUATE VISUAL LOOKOUT BY THE WACO PILOT, WHICH RESULTED IN HIS MISJUDGEMENT OF CLEARANCE BETWEEN HIS AIRCRAFT AND THE CESSNA 172 AND A SUBSEQUENT COLLISION.

- 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. 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.
