## Analysis

ON AN INSTRUCTIONAL FLT, THE STUDENT PLT & INSTRUCTOR (CFI) MADE AN ILS LOW APCH TO RWY 30R. DRG A GO-ARND (MISSED APCH)A TWR CTLR OBSVD A 'LIGHT TRACE OF SMOKE' EMANATING FM THE ENG EXHAUST. SHORTLY THEREAFTER, THE ACFT 'BANKED HARD TO THE LEFT AND APPEARED TO STALL.'  SUBSEQUENTLY, IT IMPACTED THE GND IN APRX A 20 DEG NOSE DWN, SLIGHTLY LEFT WING LOW, ATTITUDE. IMPACT OCCURRED APRX 1000' SE FM THE DEP END OF RWY 30R. THE FUSELAGE & INBRD WING SECTIONS WERE BADLY BURNED.MINIMAL ROTATIONAL DMG WAS FND ON THE PROP/PROP SPINNER. NO PREIMPACT PART FAILURE OR MALFUNCTION WAS FND DRG AN EXAM OFTHE WRECKAGE. HOWEVER, THE 3 PSN, AUX FUEL BOOST PUMP SW (INSTALLED IAW AD 87-08-05 & BEECH SB 2033) WAS FND IN THE HI BOOST PSN. THE RESPECTIVE FUEL TRUCK HAD BEEN DRAINED FOR MAINT BFR SAMPLES COULD BE OBTAINED. MAINT PSNL NOTED PARTICU-LATE IN THE FUEL, BUT NONE WAS FND IN THE ACFT FUEL SCREENS. AFTER MINOR REPAIRS, THE ENG STARTED & OPERD NORMALLY. THE FLT MANUAL PROHIBITS USE OF HI BOOST, EXCEPT WHEN THE ENG DRIVEN PUMP FAILS AS EVIDENCED BY ZERO FUEL FLOW.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19861126086169A](https://openairdocs.org/incident/19861126086169A), Nov 26, 1986: Beech A36TC, Bakersfield, CA, Destroyed, 2 fatal. Use of fuel boost pump stopped engine due to over rich fuel mixture on a go around. Aircraft stalled and crashed.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
