Narrative:

WX cavu entire east coast. High winds and low level wind shear. Reported winds on ATIS were 340 degrees, 15 KTS, gusting 25. ILS approach to runway 06 landing on runway 01. Previous aircraft (small jet) reported approximately plus or minus 10 KTS on final and very rough ride. I set up on base leg with approach flaps (1/2) due to high winds. Crab approach to 100 KTS at threshold -- at flare 85-80 KTS aligned aircraft with centerline from left crab -- just at touch down a strong gust lifted right wing or lowered left wing to cause me to hit left main and nose simultaneously -- porpoised into air -relanded, taxi to passenger pickup. Shut off right engine for passenger boarding (1). Flew 1.4 hours to orf. On shut down discovered left propeller struck ground -- curled all 3 blades about 1-2 inches. Very similar wind conditions at orf but less crosswind -- landing not hard at orf. Suspect propeller strike on bounce at teb due to low level wind shear and sudden gust at flare. Geometry aggravated due to 1/2 flaps and lower at flare. No pilot factor or fatigue involved. Plenty of rest night before. Flight time from ith -- teb equals 0.8 -- absolutely clear WX. No wake turbulence. Just a real inopportune level gust and wrong flap configuration (should have been full down) contributed to this incident. Repairs about $15K -- 3 propeller blades engine tear down -- crank/bearing replace. SOP change equals always land full flaps for better lift at touchdown.

Title: PLT OF A SMT TWIN LOST CTL DURING LNDG TOUCH DOWN CAUSING DAMAGE TO THE L PROP.

Narrative: WX CAVU ENTIRE E COAST. HIGH WINDS AND LOW LEVEL WIND SHEAR. RPTED WINDS ON ATIS WERE 340 DEGS, 15 KTS, GUSTING 25. ILS APCH TO RWY 06 LNDG ON RWY 01. PREVIOUS ACFT (SMALL JET) RPTED APPROX PLUS OR MINUS 10 KTS ON FINAL AND VERY ROUGH RIDE. I SET UP ON BASE LEG WITH APCH FLAPS (1/2) DUE TO HIGH WINDS. CRAB APCH TO 100 KTS AT THRESHOLD -- AT FLARE 85-80 KTS ALIGNED ACFT WITH CTRLINE FROM L CRAB -- JUST AT TOUCH DOWN A STRONG GUST LIFTED R WING OR LOWERED L WING TO CAUSE ME TO HIT L MAIN AND NOSE SIMULTANEOUSLY -- PORPOISED INTO AIR -RELANDED, TAXI TO PAX PICKUP. SHUT OFF R ENG FOR PAX BOARDING (1). FLEW 1.4 HRS TO ORF. ON SHUT DOWN DISCOVERED L PROP STRUCK GND -- CURLED ALL 3 BLADES ABOUT 1-2 INCHES. VERY SIMILAR WIND CONDITIONS AT ORF BUT LESS XWIND -- LNDG NOT HARD AT ORF. SUSPECT PROP STRIKE ON BOUNCE AT TEB DUE TO LOW LEVEL WIND SHEAR AND SUDDEN GUST AT FLARE. GEOMETRY AGGRAVATED DUE TO 1/2 FLAPS AND LOWER AT FLARE. NO PLT FACTOR OR FATIGUE INVOLVED. PLENTY OF REST NIGHT BEFORE. FLT TIME FROM ITH -- TEB EQUALS 0.8 -- ABSOLUTELY CLR WX. NO WAKE TURB. JUST A REAL INOPPORTUNE LEVEL GUST AND WRONG FLAP CONFIGURATION (SHOULD HAVE BEEN FULL DOWN) CONTRIBUTED TO THIS INCIDENT. REPAIRS ABOUT $15K -- 3 PROP BLADES ENG TEAR DOWN -- CRANK/BEARING REPLACE. SOP CHANGE EQUALS ALWAYS LAND FULL FLAPS FOR BETTER LIFT AT TOUCHDOWN.
