HE CONTINUED LANDING, BUT DID NOT SEE A BEIGE COLORED CESSNA 172 ON THE RUNWAY. HE REPORTED THAT THE VISIBILITY WAS VERY POOR FROM THE BACK SEAT OF THE STEARMAN. AS HE WAS ABOUT TO TOUCHDOWN, THE LANDING GEAR STRUCK THE LEFT WING OF THE CESSNA 172. THE PILOT HEARD THE SOUND OF METAL, BUT WAS UNAWARE THAT HIS PLANE HAD HIT ANOTHER AIRCRAFT UNTIL HE TAXIED TO THE HANGAR. THE CESSNA PILOT STATED THAT HE HAD WAITED FOR THE TWIN ENGINE TO LAND, ANNOUNCED HIS INTENTION ON THE RADIO, BUT SAW NO AIRCRAFT ON FINAL. HE TAXIED ONTO THE RUNWAY TO HOLD, AND THEN AS HE ADVANCED POWER TO TAKEOFF, THE COLLISION OCCURRED. THE STEARMAN WAS NOT EQUIPPED WITH A RADIO. ## Analysis (aircraft 1) THE CESSNA 172 PILOT PERFORMED HIS PREFLIGHT ENGINE RUN-UP ON THE TAXIWAY, THEN WAITED FOR A TWIN ENGINE AIRCRAFT TO LAND. HE REPORTED THAT AFTER THE TWIN ENGINE LANDED, HE RADIOED HIS INTENTION, DOUBLE CHECKED THE FINAL APPROACH AREA, AND WITH NO OTHER AIRCRAFT IN SIGHT, HE TAXIED ONTO THE RUNWAY. WHILE THE CESSNA 172 PILOT WAS WAITING FOR THE TWIN ENGINE AIRCRAFT TO LAND, A BOEING A75N1 (STEARMAN) PILOT EXTENDED HIS PATTERN AND TURNED ON A LONG FINAL APPROACH. THE STEARMAN PILOT REPORTED THAT HE DID THIS TO ALLOW THE TWIN ENGINE PLANE TO LAND AHEAD OF HIM. AS THE STEARMAN PILOT CONTINUED, HE DID NOT SEE THE BEIGE COLORED CESSNA 172 TAXI ONTO THE RUNWAY. HE REPORTED THAT THE VISIBILITY WAS POOR FROM THE BACK SEAT. ALSO, THE STEARMAN WAS NOT EQUIPPED WITH A RADIO. AS THE CESSNA PILOT ADVANCED HIS POWER TO TAKEOFF, HIS LEFT WING WAS STRUCK BY THE STEARMAN'S LANDING GEAR. ## Aircraft 1 - Registration: [N3715S](https://openairdocs.org/aircraft/N3715S), registered now, S/N 17250915, built 1963 (OpenAirDocs) - Reported make and model: CESSNA 172E - Registry model: [Cessna 172E](https://openairdocs.org/model/cessna-172e) (registry code 2072412) (OpenAirDocs) - Registry engine: [Continental 0-300 series](https://openairdocs.org/engine/continental-0-300-series) (registry code 17022, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17250915 - Airframe hours: 2835 - Engines: CONTINENTAL O-300-D 145 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: John B.
