NTSB Narrative Summary Released at Completion of Accident
Four Yakovlev YAK-50 airplanes were conducting a formation flight. The number four airplane (N509RA) was landing on the right side of runway 27R in a staggered pattern behind the number three airplane (N950MS). During the landing roll, the number four airplane's propeller and right wing leading edge struck the tail section of the number three airplane. The number four airplane had floated and landed past his intended landing point due to gusty winds. The number three airplane had crossed onto the right side of the runway during his touchdown and landing roll due to the crosswinds. The number four airplane slowed to a taxi speed after landing and began a left turn onto the taxiway. The pilot of the number four airplane did not see the number three airplane until the propeller of his airplane impacted the tail section of the number three airplane.
NTSB Probable Cause Narrative
The inadequate visual lookout of the pilot and his failure to maintain clearance from a taxiing airplane.
