Flight rulesThe regulations the flight operated under: in the US, Part 91 (general aviation), Part 121 (airlines), Part 135 (air taxi and commuter) and others; for flights abroad, the NTSB's coarser commercial or non-commercial code. Glossary
Part 91: General Aviation
Phase of flightThe stage of the flight when things started to go wrong: standing, taxi, takeoff, initial climb, en route, maneuvering, approach or landing. Glossary
Approach · IFR final approach
First occurrenceThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
In flight collision with object
Also codedOther events the NTSB coded in the sequence, such as a wire strike after a loss of power. Flight Findings uses them for its kinds of event. Glossary
Tree(s)
DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary
Destroyed

Cause areas

  • Pilot in command › IFR procedure, improper

NTSB narrative

THE FLT WAS CLRD FOR A LOC RWY 11 APCH. ABOUT 3 MIN LATER, THE 2ND-IN-COMMAND (SIC) RPRTD ' . . . WE DON'T GET THE LOCALIZER CAN YOU SEE IF WE'RE ON COURSE.' THE LAX ARTCC R-15 CTLR CONFIRMED THE FLT WAS RGT OF COURSE & BELOW THE RQRD ALT. THE ACFT'S MODE C INDCD AN ALT OF 1400 FT; THE CTLR ADZD THE FLT CREW TO MAINT AT LEAST 2300 FT UNTIL PAST THE FINAL APPROACH FIX (FAF). THE CREW THEN REPLIED THAT THEY WERE IN VMC. RADAR SVC WAS TERMINATED & A FREQ CHANGE TO TOWER WAS APPROVED. SHORTLY THEREAFTER, THE ACFT HIT A EUCALYPTUS TREE AT ABT 90 FT AGL, 2.05 MI FM THE APCH END OF THE RWY & ABT 195 FT RGT OF THE LOC. ELEV OF THE CRASH SITE WAS 101 FT; MIN DSCNT ALT (MDA) FOR THE APCH WAS 640 FT. THE 0645 PDT WX WAS, IN PART: INDEFINITE CEILING, 100 FT OBSCURED, VIS 1/8 MI WITH FOG, WIND FROM 220 DEG AT 4 KTS. NO PREIMPACT PART FAILURE OR MALFUNCTION OF THE ACFT WAS FOUND.

Probable cause

THE PILOT'S IMPROPER IFR (INSTRUMENT) PROCEDURE, AND HIS FAILURE TO MAINTAIN THE MINIMUM DESCENT ALTITUDE (MDA) FOR THE APPROACH. THE ADVERSE WEATHER WAS A RELATED FACTOR.

  • 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.
