## Analysis (aircraft 2)

THE PILOTS OF EACH ACFT STATED THEY THOUGHT THAT THE LEFT FLOAT AND PROP OF THE TAYLORCRAFT HAD COME IN CONTACT WITH THE RT WING AND RT LANDING GEAR OF THE PIPER. THE PLTS FAILED TO SEE THE OTHER ACFT IN TIME TO AVOID THE COLLISION. BOTH ACFT NOSED OVER DURING LANDING DUE TO SURFACE CONDITIONS AND LANDING GEAR DAMAGE.
