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

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 · VFR pattern final
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
Loss of engine power
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

NTSB narrative

A PASSENGER REPORTED THAT WHEN THE AIRCRAFT WAS ABOUT 6 MI FROM THE DESTINATION AIRPORT AT 6000' MSL, THE PILOT BEGAN A DESCENT BY REDUCING THE POWER TO IDLE, PLACING THE PROPELLERS TO FULL FORWARD (HIGH RPM), LOWERING THE LANDING GEAR, EXTENDING THE FLAPS, & SLOWING TO 110 KNOTS. WHEN THE AIRPLANE WENT BELOW THE INTENDED APPROACH PATH ON SHORT FINAL APPROACH, THE PILOT APPLIED POWER, BUT THE RIGHT ENGINE DID NOT RESPOND. THE PILOT STATED THAT THE AIRPLANE YAWED 80 TO 90 DEGREES TO THE RIGHT. HE SAID A STALL WAS EMINENT, SO HE REDUCED THE POWER & ROLLED THE WINGS LEVEL. THE PLANE STRUCK TREES & THE TERRAIN. AN EXAM DID NOT REVEAL ANY PRE-EXISTING ANOMALIES. A REVIEW OF THE AIRPLANE & ENGINE HANDBOOKS CAUTIONED AGAINST RAPID DESCENTS AT IDLE RPM TO AVOID LOW CYLINDER HEAD TEMPERATURES. THE ENGINE MANUAL NOTED THAT LONG DESCENTS AT LOW MANIFOLD PRESSURE COULD COOL THE ENGINE(S) EXCESSIVELY & RESULT IN UNSATISFACTORY ACCELERATION. THE PILOT DID NOT FEATHER THE RIGHT ENGINE.

Probable cause

THE PILOT DID NOT FOLLOW THE EMERGENCY PROCEDURE AFTER LOSS OF POWER IN THE RIGHT ENGINE, BY FAILING TO FEATHER THE RIGHT ENGINE AND FAILING TO MAINTAIN MINIMUM SINGLE-ENGINE CONTROL SPEED. A FACTOR RELATED TO THE ACCIDENT WAS: FAILURE OF THE PILOT TO ADHERE TO THE CAUTIONS CONCERNING OPERATION OF THE ENGINES DURING DESCENT.

  • 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.
