Narrative:

Cleared to land runway 22 lex, encountered turbulence from departing turboprop. Had a hard landing resulting in a collapsed nose wheel, stopped aircraft on runway, winds were light. Viewpoints of why: first of all, as an airline pilot, flying the large transport, I was not successful in converting my habit patterns to light plane flying. The spacing behind the departing 'small' turboprop seemed ok if I had been flying the large transport but proved to be too close for the light airplane I now was in. Should have opted for greater spacing. Once in the landing turbulence, I tried to save the landing, since there was plenty of runway. I should have gone around and did not recognize the need based on my heavy jet mind frame. When in trouble my natural reactions to trying to save the landing reverted back to actions on the large transport. I believe that fatigue was a big factor in my poor performance since I had never had this problem before.

Title: SMA ACFT CAUGHT IN VORTICES FROM ACFT TAKING OFF. PLT OF SMA LOST CTL AND COLLAPSED NOSE WHEEL IN HARD LNDG.

Narrative: CLRED TO LAND RWY 22 LEX, ENCOUNTERED TURB FROM DEPARTING TURBOPROP. HAD A HARD LNDG RESULTING IN A COLLAPSED NOSE WHEEL, STOPPED ACFT ON RWY, WINDS WERE LIGHT. VIEWPOINTS OF WHY: FIRST OF ALL, AS AN AIRLINE PLT, FLYING THE LGT, I WAS NOT SUCCESSFUL IN CONVERTING MY HABIT PATTERNS TO LIGHT PLANE FLYING. THE SPACING BEHIND THE DEPARTING 'SMALL' TURBOPROP SEEMED OK IF I HAD BEEN FLYING THE LGT BUT PROVED TO BE TOO CLOSE FOR THE LIGHT AIRPLANE I NOW WAS IN. SHOULD HAVE OPTED FOR GREATER SPACING. ONCE IN THE LNDG TURB, I TRIED TO SAVE THE LNDG, SINCE THERE WAS PLENTY OF RWY. I SHOULD HAVE GONE AROUND AND DID NOT RECOGNIZE THE NEED BASED ON MY HVY JET MIND FRAME. WHEN IN TROUBLE MY NATURAL REACTIONS TO TRYING TO SAVE THE LNDG REVERTED BACK TO ACTIONS ON THE LGT. I BELIEVE THAT FATIGUE WAS A BIG FACTOR IN MY POOR PERFORMANCE SINCE I HAD NEVER HAD THIS PROBLEM BEFORE.
