Different sources suggest the only problem with this aircraft was that it was just too big for PSA.  Right now, a plane built by Air Tractor Inc. has this number.  But the plane in the photo went on to other owners on other continents:  probably including Aero Peru, and Operation Blessing International Relief (as P4-MED).  All its different numbers have been de-registered.  Five unused Mary Jayne cards MJ592 are available.  Grades: 1
