## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-23) A/C PILOT/OWNER RICHARD DAVIS STATED IN A PHONE CONVERSATION THAT THE A/C LOST POWER ABOUT 25 FT IN THE AIR ON DEPARTING REDDING AIRPORT. HE ATTEMPTED TO RE EXTEND THE LANDING GEAR AND LAND ON THE REMAINING RUNWAY. THE LEFT MAIN GEAR COLLAPSED, RESULTING IN MINOR DAMAGE TO THE A/C. THE LOSS OF POWER WAS DUE TO AN OWNER FABRICATED LINKAGE ON A BUTTERFLY VALVE IN THE AFT AIR BOX. THE LINKAGE CONTROLS TWO BUTTERFLY'S TO DIRECT AIR FLOW IN THE BOX. THE FAILURE CAUSED BOTH BUTTERFLY VALVE TO CLOSE RESTRICTING ENGINE INLET AIR FLOW AND CAUSING A LOSS OF POWER. DAMAGE ACCORDING TO OBSERVERS INVOLVES THE LOWER PORTION OF THE LEFT GEAR LEG AND WHEEL, DAMAGE TO THE LEFT WING TIP AND FLAP.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
