Narrative:

Aircraft was VFR being vectored to runway 28R in MVFR conditions. Aircraft was cleared to land approximately 1 mi from runway 28R at 1200 AGL with instructions to maintain best forward speed. An medium large transport was cleared for takeoff on runway 28R at this time with numerous airliner traffic following. Wind was 150 at 7. Landing was accomplished at higher than normal airspeed. Aircraft was instructed to exit runway 28R as soon as possible as traffic was on short final. Aircraft exited the runway on taxiway N7 at approximately 40 KTS. Directional control was lost at this point with a resulting gndloop. No damage to aircraft -- only the pilot's ego. Contributing factors: mixing of high/lows approach speed traffic. Higher than normal approach speed. Landing with quartering tailwind. Attempting to comply with controller's instruction. Possible wake turbulence from departing medium large transport. Human factors: pilot should have initiated a go around when cleared to land -- too high and too fast. Pilot should not have attempted turnoff at high speed taxiway. System factors: controllers should have more training and consideration of mixed speed traffic. The high/fast scenario is the rule rather than the exception at larger airports.

Title: SMT CARGO ACFT REQUESTED TO MAINTAIN BEST FORWARD SPD. COMPLIES AND LANDS ABOVE NORMAL SPD. REQUESTED EXIT RWY AS SOON AS POSSIBLE. DOES SO, BUT TOO FAST. GND LOOPS.

Narrative: ACFT WAS VFR BEING VECTORED TO RWY 28R IN MVFR CONDITIONS. ACFT WAS CLRED TO LAND APPROX 1 MI FROM RWY 28R AT 1200 AGL WITH INSTRUCTIONS TO MAINTAIN BEST FORWARD SPD. AN MLG WAS CLRED FOR TKOF ON RWY 28R AT THIS TIME WITH NUMEROUS AIRLINER TFC FOLLOWING. WIND WAS 150 AT 7. LNDG WAS ACCOMPLISHED AT HIGHER THAN NORMAL AIRSPD. ACFT WAS INSTRUCTED TO EXIT RWY 28R AS SOON AS POSSIBLE AS TFC WAS ON SHORT FINAL. ACFT EXITED THE RWY ON TAXIWAY N7 AT APPROX 40 KTS. DIRECTIONAL CTL WAS LOST AT THIS POINT WITH A RESULTING GNDLOOP. NO DAMAGE TO ACFT -- ONLY THE PLT'S EGO. CONTRIBUTING FACTORS: MIXING OF HIGH/LOWS APCH SPD TFC. HIGHER THAN NORMAL APCH SPD. LNDG WITH QUARTERING TAILWIND. ATTEMPTING TO COMPLY WITH CTLR'S INSTRUCTION. POSSIBLE WAKE TURB FROM DEPARTING MLG. HUMAN FACTORS: PLT SHOULD HAVE INITIATED A GAR WHEN CLRED TO LAND -- TOO HIGH AND TOO FAST. PLT SHOULD NOT HAVE ATTEMPTED TURNOFF AT HIGH SPD TAXIWAY. SYS FACTORS: CTLRS SHOULD HAVE MORE TRAINING AND CONSIDERATION OF MIXED SPD TFC. THE HIGH/FAST SCENARIO IS THE RULE RATHER THAN THE EXCEPTION AT LARGER ARPTS.
