PLT ON CHECKOUT IN BE36 STRIKES PROP ON FLARE WHEN GEAR FAILS TO EXTEND FULLY.

Narrative

THIS WAS MY 1ST FLT IN MODEL (A36). I HAD 1 PREVIOUS FLT IN BE33 DVFR AND ACCOMPLISHED 6 TKOFS AND LNDGS 4 WKS PRIOR WITH SAME INSTRUCTOR. I WAS ASKED ABOUT EMER GEAR EXTENSION. I QUOTED THE PROC FROM THE AFM. INSTRUCTOR SAID THE ANSWER WAS TO GET OUT THE CHKLIST. I SET UP FOR ILS AT ZZZ USING THE GARMIN GNS430. I WAS HIGH AND FAST SO I REDUCED PWR AND EXTENDED THE LNDG GEAR TO HELP REDUCE SPD. THE INSTRUCTOR STATED THAT WE WERE 'IN THE YELLOW' (AIRSPD INDICATOR RANGE); SO I PLACED THE LNDG GEAR SWITCH IN THE 'UP' POS. I NOTICED THE YELLOW GEAR IN TRANSITION LIGHT ON. ONCE I SLOWED TO BELOW 150 KTS I PUT DOWN 10 DEGS FLAPS AND WATCHED THE FLAP INDICATOR SHOW 10 DEGS. I PLACED THE GEAR SWITCH IN THE 'DOWN' POS. I NOTED A SLOWING OF THE ACFT. I SWITCHED ON THE TAXI AND LNDG LIGHTS INDIVIDUALLY AND BOTH CAME ON. THE LNDG LIGHT IS ATTACHED TO THE NOSE GEAR STRUT. I HAD TO LOOK AROUND AND MOVE THE CTL COLUMN TO SELECT THESE SWITCHES AS THEY WERE NOT VIEWABLE FROM MY POS. I HAD ALL THE EXTERIOR LIGHTING (STROBES; NAV LIGHTS; ROTATING BEACON) AND THE INST LIGHTS ON. ON PREFLT THERE WERE PROBS WITH THE #1 NAV/COM (GNS430) EMITTING A LOUD FEEDBACK NOISE IN THE HEADSETS. SWITCHING TO THE #2 NAV/COM THE FEEDBACK NOISE DISAPPEARED. ONCE THE ENG WAS STARTED THE NOISE DISAPPEARED FROM THE #1 NAV/COM AND #2 NAV/COMS. THIS ACFT HAD RECENTLY BEEN WRITTEN UP WITH AUDIO PROBS; AND SIGNED OFF AS FIXED PRIOR TO THIS FLT. I PERFORMED A GUMPS CHK AND SWITCHED MY VISION TO OUTSIDE FOLLOWING OF THE VASI TO THE LNDG. OVER THE NUMBERS I REDUCED THE THROTTLE TO IDLE AND DID NOT GET A GEAR WARNING HORN. I HELD OFF THE LNDG; BUT THOUGHT I WAS GETTING TOO LOW. I HEARD SOMETHING SCRAPE AND I IMMEDIATELY INCREASED PITCH AND ADDED PWR. THE SCRAPING STOPPED AND I STARTED MY GAR. THE ENG DEVELOPED FULL PWR AND ALL ENG INSTS WERE IN THE GREEN. I NOTICED A REFLECTION; THAT I HAD NOT SEEN BEFORE; IN THE PROP; WHICH THE INSTRUCTOR SAID WAS DUE TO MY HAVING BOTH THE LNDG AND TAXI LIGHTS ON. APPROX 500 FT BEFORE TURNING XWIND I NOTICED THAT THE YELLOW GEAR IN TRANSITION LIGHT WAS ON. I SAW THAT THE LNDG GEAR CIRCUIT BREAKER WAS POPPED (POSSIBLE ELECTRICAL OVERLOAD); SO I RESET IT; AND IMMEDIATELY GOT 3 GREEN LIGHTS. I MADE A NORMAL CLOSE IN VFR PATTERN AND LNDG ON RWY 17 WITHOUT FURTHER INCIDENT. THE ACFT HANDLED NORMALLY; AND ALL ENG INDICATORS WERE IN THE GREEN. HUMAN PERFORMANCE FACTORS: UNFAMILIARITY WITH ACFT; GEAR CYCLE PROCESS AND PLACEMENT OF SWITCHES. THE CTL COLUMN BLOCKS MANY OF THE LIGHTS AND SWITCHES; INCLUDING THE GEAR HANDLE; FLAP HANDLE AND LNDG GEAR TRANSITION AND GREEN LIGHTS. NEITHER THE PLT OR THE INSTRUCTOR REVERIFIED 3 GREEN LIGHTS ON SHORT FINAL. I HAD THE LNDG GEAR LIGHT SHINING; SINCE THIS LIGHT IS ATTACHED TO THE NOSE STRUT; AND I FELT THE ACFT SLOWING. I THOUGHT THE LNDG GEAR; OR AT LEAST THE NOSE GEAR; WAS DOWN. THE ACFT FLEW AWAY FROM THE RWY AND HANDLED NORMALLY. I DECIDED TO ACCEPT THE ACFT EVEN AFTER GETTING A SIMILAR FEEDBACK IN THE HEADSETS THAT HAD JUST BEEN FIXED. ONCE I NOTICED SOMETHING WAS WRONG ON LNDG (SCRAPING NOISE); I INCREASED PITCH AND ADDED PWR TO STOP THE NOISE. I CLBED AND ASKED FOR HELP FROM THE INSTRUCTOR TO DETERMINE WHAT IF ANYTHING HAD HAPPENED. ONCE BACK ON THE GND I TERMINATED THE FLT TO CHK FOR DAMAGE.
