Narrative:
On apr/thu/02 at approximately XA30 we were on our final approach into 3CK, lake in the hills. The other pilot was flying from the left seat and I was the PNF in the right seat. The conditions that day were clear and the runway was dry. The winds were strong out of the west and gusty. (I believe they were 280 degrees at 22 KTS gusting to 36 KTS). As per the manual (1/2 of the gust factor in excess of 5 KTS). We added 7 KTS to vref and our targeted airspeed was 103 KTS (96 + 7=103). PF had about 22 hours in the aircraft and had landed it several times. He had seen several lndgs before, but this was his first attempt at landing there. We had discussed this approach and landing at 3CK and I told him my hands would be very close to the controls as a back-up. The approach was normal and on-speed and the flare was at the normal ht. Then the PF pushed forward to make the landing, which resulted in a firm 3-POINT landing. As soon as the airplane touched down, PF extended the thrust reversers. Due to the firm landing, the aircraft bounced slightly off the ground, came down and bounced again. At this point, the bounce was not severe enough to warrant a go around, however, each bounce got progressively worse. My guess is that we bounced about 3-4 times. After the second or third bounce, I came on the controls but could not control the aircraft. At this point, the aircraft was too slow and behind the power curve to attempt a go around. The last bounce was very high and resulted in damage to the nose gear. When the aircraft came to a stop, we shut it down and were eventually towed off the runway. I don't remember positively if I extended the speed brakes or not, but I don't think I ever did because we were never established on the runway with positive braking. In my opinion, the reversers were extended too soon. You do not want to extend the speed brakes or thrust reversers until the aircraft is on the runway, with the nose gear down, and brakes having been applied. To quote the manual for short-field lndgs: 'for landing utilizing thrust reversers, after touchdown on the mains, lower the nose, apply wheel brakes, extend the speed brakes, and deploy the thrust reversers.'

Title: C560 PLT MADE A HARD LNDG AND BOUNCED BACK IN THE AIR 4 TIMES BEFORE COMING TO A STOP IN THE RWY OVERRUN AREA RESULTING IN DAMAGE TO THE NOSE GEAR. ACFT WAS STRANDED AND TOWED OFF THE RWY.
Narrative: ON APR/THU/02 AT APPROX XA30 WE WERE ON OUR FINAL APCH INTO 3CK, LAKE IN THE HILLS. THE OTHER PLT WAS FLYING FROM THE L SEAT AND I WAS THE PNF IN THE R SEAT. THE CONDITIONS THAT DAY WERE CLR AND THE RWY WAS DRY. THE WINDS WERE STRONG OUT OF THE W AND GUSTY. (I BELIEVE THEY WERE 280 DEGS AT 22 KTS GUSTING TO 36 KTS). AS PER THE MANUAL (1/2 OF THE GUST FACTOR IN EXCESS OF 5 KTS). WE ADDED 7 KTS TO VREF AND OUR TARGETED AIRSPD WAS 103 KTS (96 + 7=103). PF HAD ABOUT 22 HRS IN THE ACFT AND HAD LANDED IT SEVERAL TIMES. HE HAD SEEN SEVERAL LNDGS BEFORE, BUT THIS WAS HIS FIRST ATTEMPT AT LNDG THERE. WE HAD DISCUSSED THIS APCH AND LNDG AT 3CK AND I TOLD HIM MY HANDS WOULD BE VERY CLOSE TO THE CTLS AS A BACK-UP. THE APCH WAS NORMAL AND ON-SPD AND THE FLARE WAS AT THE NORMAL HT. THEN THE PF PUSHED FORWARD TO MAKE THE LNDG, WHICH RESULTED IN A FIRM 3-POINT LNDG. AS SOON AS THE AIRPLANE TOUCHED DOWN, PF EXTENDED THE THRUST REVERSERS. DUE TO THE FIRM LNDG, THE ACFT BOUNCED SLIGHTLY OFF THE GND, CAME DOWN AND BOUNCED AGAIN. AT THIS POINT, THE BOUNCE WAS NOT SEVERE ENOUGH TO WARRANT A GAR, HOWEVER, EACH BOUNCE GOT PROGRESSIVELY WORSE. MY GUESS IS THAT WE BOUNCED ABOUT 3-4 TIMES. AFTER THE SECOND OR THIRD BOUNCE, I CAME ON THE CTLS BUT COULD NOT CTL THE ACFT. AT THIS POINT, THE ACFT WAS TOO SLOW AND BEHIND THE PWR CURVE TO ATTEMPT A GAR. THE LAST BOUNCE WAS VERY HIGH AND RESULTED IN DAMAGE TO THE NOSE GEAR. WHEN THE ACFT CAME TO A STOP, WE SHUT IT DOWN AND WERE EVENTUALLY TOWED OFF THE RWY. I DON'T REMEMBER POSITIVELY IF I EXTENDED THE SPD BRAKES OR NOT, BUT I DON'T THINK I EVER DID BECAUSE WE WERE NEVER ESTABLISHED ON THE RWY WITH POSITIVE BRAKING. IN MY OPINION, THE REVERSERS WERE EXTENDED TOO SOON. YOU DO NOT WANT TO EXTEND THE SPD BRAKES OR THRUST REVERSERS UNTIL THE ACFT IS ON THE RWY, WITH THE NOSE GEAR DOWN, AND BRAKES HAVING BEEN APPLIED. TO QUOTE THE MANUAL FOR SHORT-FIELD LNDGS: 'FOR LNDG UTILIZING THRUST REVERSERS, AFTER TOUCHDOWN ON THE MAINS, LOWER THE NOSE, APPLY WHEEL BRAKES, EXTEND THE SPD BRAKES, AND DEPLOY THE THRUST REVERSERS.'
