Narrative:
We were approaching ric from the west to land on runway 20. The captain was making the approach and landing. Wind was from 280 degrees at 10-15 KTS. A stabilized approach was established before 500' above field elevation with a red over white VASI display. Continuous light chop was experienced during final approach, so I aimed for 3-4 KTS over target airspeed. After commencing the flare at about 525' and being within 15-20' from T/D, the perceived sink rate increased. I increased back pressure to check the rate of descent and touched down firmly. The aircraft skipped, and as it did the upwind (right) wing rose to about a 10-15 degree angle. The right wing was lowered and a second T/D was accomplished simultaneously, the second being smoother than the first. The landing was accomplished within the first 1000-2000' of the runway on centerline and the rollout and taxi to the gate were normal. The aircraft was inspected with care during the en route walkaround and nothing was found amiss. As we critiqued the approach and landing the first officer said that, 'the bottom seemed to drop out in close,' and I had to agree that was the feeling I got also. Runway 20 at ric is parallel to the main ramp area and the bldgs are relatively close to the runway on the right side. We both felt that this could cause a blocking effect of the steady state wind when close to T/D with the wind from the west as it was during this approach and landing. I have both seen and experienced this effect at ord, runway 9L, with a quartering headwind from the northeast. As the wind goes over the 2 large hangars on the upwind side of this runway, strange things happen to what appear to be perfectly normal approachs just prior to T/D. I think this was the cause of the increased sink rate in close at ric. The few extra KTS over target speed probably helped ease the first T/D, but contributed to the following skip, a mixed contribution. No known passenger comments were made about the approach and landing. Supplemental information from acn 141781: after beginning to flare, the aircraft seemed to quit flying and we had an increased rate of descent.

Title: ACR MLG APCHING IN TURBULENT AND WINDY CONDITIONS BOUNCES UPON LNDG.
Narrative: WE WERE APCHING RIC FROM THE W TO LAND ON RWY 20. THE CAPT WAS MAKING THE APCH AND LNDG. WIND WAS FROM 280 DEGS AT 10-15 KTS. A STABILIZED APCH WAS ESTABLISHED BEFORE 500' ABOVE FIELD ELEVATION WITH A RED OVER WHITE VASI DISPLAY. CONTINUOUS LIGHT CHOP WAS EXPERIENCED DURING FINAL APCH, SO I AIMED FOR 3-4 KTS OVER TARGET AIRSPD. AFTER COMMENCING THE FLARE AT ABOUT 525' AND BEING WITHIN 15-20' FROM T/D, THE PERCEIVED SINK RATE INCREASED. I INCREASED BACK PRESSURE TO CHK THE RATE OF DSNT AND TOUCHED DOWN FIRMLY. THE ACFT SKIPPED, AND AS IT DID THE UPWIND (RIGHT) WING ROSE TO ABOUT A 10-15 DEG ANGLE. THE RIGHT WING WAS LOWERED AND A SECOND T/D WAS ACCOMPLISHED SIMULTANEOUSLY, THE SECOND BEING SMOOTHER THAN THE FIRST. THE LNDG WAS ACCOMPLISHED WITHIN THE FIRST 1000-2000' OF THE RWY ON CENTERLINE AND THE ROLLOUT AND TAXI TO THE GATE WERE NORMAL. THE ACFT WAS INSPECTED WITH CARE DURING THE ENRTE WALKAROUND AND NOTHING WAS FOUND AMISS. AS WE CRITIQUED THE APCH AND LNDG THE F/O SAID THAT, 'THE BOTTOM SEEMED TO DROP OUT IN CLOSE,' AND I HAD TO AGREE THAT WAS THE FEELING I GOT ALSO. RWY 20 AT RIC IS PARALLEL TO THE MAIN RAMP AREA AND THE BLDGS ARE RELATIVELY CLOSE TO THE RWY ON THE RIGHT SIDE. WE BOTH FELT THAT THIS COULD CAUSE A BLOCKING EFFECT OF THE STEADY STATE WIND WHEN CLOSE TO T/D WITH THE WIND FROM THE W AS IT WAS DURING THIS APCH AND LNDG. I HAVE BOTH SEEN AND EXPERIENCED THIS EFFECT AT ORD, RWY 9L, WITH A QUARTERING HEADWIND FROM THE NE. AS THE WIND GOES OVER THE 2 LARGE HANGARS ON THE UPWIND SIDE OF THIS RWY, STRANGE THINGS HAPPEN TO WHAT APPEAR TO BE PERFECTLY NORMAL APCHS JUST PRIOR TO T/D. I THINK THIS WAS THE CAUSE OF THE INCREASED SINK RATE IN CLOSE AT RIC. THE FEW EXTRA KTS OVER TARGET SPD PROBABLY HELPED EASE THE FIRST T/D, BUT CONTRIBUTED TO THE FOLLOWING SKIP, A MIXED CONTRIBUTION. NO KNOWN PAX COMMENTS WERE MADE ABOUT THE APCH AND LNDG. SUPPLEMENTAL INFO FROM ACN 141781: AFTER BEGINNING TO FLARE, THE ACFT SEEMED TO QUIT FLYING AND WE HAD AN INCREASED RATE OF DSNT.
