THEY BEGAN A MANEUVER CALLED A 'MIRROR FLY-BY' IN WHICH THE BUCKER WAS ROLLED UPSIDE DOWN & THE PITTS WAS FLOWN UNDERNEATH IT. DUE TO THE AIR FLOW OVER THE WINGS THE ACFT WERE PUSHED APART AS THEY FLEW IN FORMATION; HOWEVER, THE PLTS ELECTED TO MODIFY THE MANEUVER BY HAVING THE PITTS MOVE FORWARD. AS THE ACFT WERE POSITIONED TO WHERE THE WINGS WERE NOT OVERLAPPED, THE ACFT CONVERGED INTO EACH OTHER. SUBSEQUENTLY, THE PROP OF THE BUCKER STRUCK THE PITT'S VERTICAL FIN & RUDDER, SUBSTANTIALLY DAMAGING THE PITTS. HOWEVER, BOTH ACFT WERE LANDED SAFELY. ## Aircraft 1 - Registration: [N1947G](https://openairdocs.org/aircraft/N1947G), registered now, S/N 218, built 1947 (OpenAirDocs) - Reported make and model: Bucker Flugzeugbau JUNGMANN - Registry model: [Aero Z BUECKER 131](https://openairdocs.org/model/aero-z-buecker-131) (registry code 0170102) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Airplane - Serial number: 218 - Airframe hours: 1237 - Engines: CONTINENTAL IO-360-A2B reciprocating - Damage: Minor damage - Flight: Part 91 - Registered owner: Aerp Sport Inc. - Airworthiness certificate: Standard, Aerobatic - Last inspection: Annual, October 10, 1983, 0 hours before - Departed: SGJ, ST.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. --- OpenAirDocs.org is an independent research project of [Contrail Labs](https://contraillabs.com/). It is not affiliated with the FAA or the NTSB.
