Me thinks part of the problem, with the two generated profiles, may be that there are two airframe IDs and each one lists the aircraft type slightly different;
for the same bird C/N 510-0126:
G-FKBK linking data:
Airframe ID: 641861
Aircraft Model: 2008 CESSNA AIRCRAFT COMPANY CESSNA 510
C/N 510-0126
N826CM linking data:
Airframe ID: 313082
Aircraft Model: 2008 Cessna 510
C/N 510-0126
The database may be interpetting this as two entirely different frames?
