Narrative:

Approached avp at approximately XA15 local for ILS runway 4. WX at the time was 1300 ft overcast and 10 mi visibility. Tower reported winds were 120 degrees at 18 KTS, gusting to 25 KTS. The approach was normal except for excessive wind correction required to hold the localizer. Copilot completed the landing checklist prior to breaking out of the cloud deck. Occasional moderate chop was experienced on a mi final but subsided upon reaching the runway. Vref speed was 126 KTS to short final where aircraft was slowed to vref of 116 KTS to the flare. The aircraft touched down just past the first taxiway B. The aircraft seemed to balloon and float a bit due the excess speed and touched down a second and final time approximately 300 ft further down the runway. The touchdown was not hard, and on the right main gear first. The aircraft seemed to track normally once the nosewheel was on the ground and upon reaching the next taxiway C, started pulling left. It felt as if the left main tires were blown. Right braking and steering were applied in order to keep the aircraft on the runway. We slid to a stop with around 2000 ft of runway remaining, 20 ft to the left of centerline. We immediately shut down the engines and electrical and evacuate/evacuationed the aircraft. Upon examining the aircraft the left main gear was found partially retracted. The left wingtip was on the ground (runway). Callback conversation with reporter revealed the following information: the cause of this incident is under investigation and may be considered crew error. The up and down actuator sheared off on the left main gear of this C650, during the landing. This reporter captain states that the side load brace actuator should have actually sheared if pilot error was involved. (The side load brace locks into position at a 45 degree angle.) reporter adds that this gear is considered to have a good reputation and it is his understanding that it is scheduled to go on the citation 10.

Title: CITATION III, A CESSNA 650 TYPE, HAS L GEAR COLLAPSE ON LNDG PROC XWIND LNDG ROLLOUT.

Narrative: APCHED AVP AT APPROX XA15 LCL FOR ILS RWY 4. WX AT THE TIME WAS 1300 FT OVCST AND 10 MI VISIBILITY. TWR RPTED WINDS WERE 120 DEGS AT 18 KTS, GUSTING TO 25 KTS. THE APCH WAS NORMAL EXCEPT FOR EXCESSIVE WIND CORRECTION REQUIRED TO HOLD THE LOC. COPLT COMPLETED THE LNDG CHKLIST PRIOR TO BREAKING OUT OF THE CLOUD DECK. OCCASIONAL MODERATE CHOP WAS EXPERIENCED ON A MI FINAL BUT SUBSIDED UPON REACHING THE RWY. VREF SPD WAS 126 KTS TO SHORT FINAL WHERE ACFT WAS SLOWED TO VREF OF 116 KTS TO THE FLARE. THE ACFT TOUCHED DOWN JUST PAST THE FIRST TXWY B. THE ACFT SEEMED TO BALLOON AND FLOAT A BIT DUE THE EXCESS SPD AND TOUCHED DOWN A SECOND AND FINAL TIME APPROX 300 FT FURTHER DOWN THE RWY. THE TOUCHDOWN WAS NOT HARD, AND ON THE R MAIN GEAR FIRST. THE ACFT SEEMED TO TRACK NORMALLY ONCE THE NOSEWHEEL WAS ON THE GND AND UPON REACHING THE NEXT TXWY C, STARTED PULLING L. IT FELT AS IF THE L MAIN TIRES WERE BLOWN. R BRAKING AND STEERING WERE APPLIED IN ORDER TO KEEP THE ACFT ON THE RWY. WE SLID TO A STOP WITH AROUND 2000 FT OF RWY REMAINING, 20 FT TO THE L OF CTRLINE. WE IMMEDIATELY SHUT DOWN THE ENGS AND ELECTRICAL AND EVACED THE ACFT. UPON EXAMINING THE ACFT THE L MAIN GEAR WAS FOUND PARTIALLY RETRACTED. THE L WINGTIP WAS ON THE GND (RWY). CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE CAUSE OF THIS INCIDENT IS UNDER INVESTIGATION AND MAY BE CONSIDERED CREW ERROR. THE UP AND DOWN ACTUATOR SHEARED OFF ON THE L MAIN GEAR OF THIS C650, DURING THE LNDG. THIS RPTR CAPT STATES THAT THE SIDE LOAD BRACE ACTUATOR SHOULD HAVE ACTUALLY SHEARED IF PLT ERROR WAS INVOLVED. (THE SIDE LOAD BRACE LOCKS INTO POS AT A 45 DEG ANGLE.) RPTR ADDS THAT THIS GEAR IS CONSIDERED TO HAVE A GOOD REPUTATION AND IT IS HIS UNDERSTANDING THAT IT IS SCHEDULED TO GO ON THE CITATION 10.
