Narrative:

Wind shear on final approach into bvi. Wind was 90 degrees to runway, then straight down runway. When I was set up for landing in flare over runway, experienced a downdraft. Added power. The aircraft hit on the mains and bounced up into the air. This caused the aircraft to be in an extreme angle of attack. Pushed the nose down--the aircraft porpoised back down onto the runway and bounced up into the air again. Applied full power and made a go around. The flaps retracted normally. After reporting to tower I was going around, entered into a normal traffic pattern. When I went to put the flaps down again, they were inoperative. Made a normal no-flaps landing, everything seemed fine, braking action was normal. Called ground and continued a normal taxi to terminal. Tower reported a northwest wind at 7 KTS. I feel I should have been advised that it was not just a right crosswind, but it was shifting as previously stated. This phenomena was observed by other pilots that day also. I didn't discover that there was any damage done to the aircraft until after I parked it. I noticed the nose wheel pant had cracked and a couple of small pieces were missing. One blade of the propeller was bent back about 1 1/2'. Also noticed underside of cowling was rippled.

Title: PLT OF SMA MADE A HARD PORPOISED LNDG, MADE GO AROUND, LANDED. TAXI NORMAL. POSTFLT INSPECTION REVEALED DAMAGED NOSE WHEEL PANT, PROPELLER BENT, FLAPS WOULD NOT LOWER.

Narrative: WIND SHEAR ON FINAL APCH INTO BVI. WIND WAS 90 DEGS TO RWY, THEN STRAIGHT DOWN RWY. WHEN I WAS SET UP FOR LNDG IN FLARE OVER RWY, EXPERIENCED A DOWNDRAFT. ADDED PWR. THE ACFT HIT ON THE MAINS AND BOUNCED UP INTO THE AIR. THIS CAUSED THE ACFT TO BE IN AN EXTREME ANGLE OF ATTACK. PUSHED THE NOSE DOWN--THE ACFT PORPOISED BACK DOWN ONTO THE RWY AND BOUNCED UP INTO THE AIR AGAIN. APPLIED FULL PWR AND MADE A GAR. THE FLAPS RETRACTED NORMALLY. AFTER RPTING TO TWR I WAS GOING AROUND, ENTERED INTO A NORMAL TFC PATTERN. WHEN I WENT TO PUT THE FLAPS DOWN AGAIN, THEY WERE INOP. MADE A NORMAL NO-FLAPS LNDG, EVERYTHING SEEMED FINE, BRAKING ACTION WAS NORMAL. CALLED GND AND CONTINUED A NORMAL TAXI TO TERMINAL. TWR RPTED A NW WIND AT 7 KTS. I FEEL I SHOULD HAVE BEEN ADVISED THAT IT WAS NOT JUST A RIGHT XWIND, BUT IT WAS SHIFTING AS PREVIOUSLY STATED. THIS PHENOMENA WAS OBSERVED BY OTHER PLTS THAT DAY ALSO. I DIDN'T DISCOVER THAT THERE WAS ANY DAMAGE DONE TO THE ACFT UNTIL AFTER I PARKED IT. I NOTICED THE NOSE WHEEL PANT HAD CRACKED AND A COUPLE OF SMALL PIECES WERE MISSING. ONE BLADE OF THE PROP WAS BENT BACK ABOUT 1 1/2'. ALSO NOTICED UNDERSIDE OF COWLING WAS RIPPLED.
