Gerald Yagen's Avro 504K Project

Jerry is the owner of the Aviation Institute of Maintenance being FAA approved schools, operating in Georgia, Indiana, Missouri, Pennsylvania, Texas, Orlando and Virginia.

Each of the seven schools are currently constructing different WW1 replicas (see: http://www.aimschool.com/?page_id=138). However as none of the schools selected the AVRO 504, Jerry made it his own personal project. He commissioned Pur Sang Aero Historic (Argentina) to construct the first 504 which proved to be a great success; consequently, Jerry commissioned a second AVRO 504. The first aircraft is now operational in the USA.

Jerry is also the owner of a Military Aviation Museum located at Virginea Beach VA. The Avro LV-X373 is now located at this museum. For more information Link To: www.MilitaryAviationMuseum.org
