AS THE PLT RECVD FROM THE DESCENDING SPIRAL THE INBOARD AND OUTBOARD AILERON HINGE RIVETS WERE SHEARED. THE ALTITUDE DEVIATION OCCURRED IN IMC WEATHER. AN EMERGENCY WAS DECLARED WITH ATC. VECTORS WERE PROVIDED TO JFK APRT FOR A VFR LANDING. THE FLT LANDED WITHOUT FURTHER INCIDENT. THE PLT REPORTED THAT AS THE ACFT CLIMBED THROUGH 19000FT AT 100 KTS A LOUD BANK WAS HEARD AND THE ACFT STARTED SHAKING. THE PLT DISENGAGED THE AUTOPLT AND LOWERED THE NOSE. HE STATED THE ACFT ENTERED A RIGHT DESCENDING SPIRAL. HE COULD NOT MOVE THE AILERON AND RECOVERED WITH RUDDER AND ELEVATOR. THE RIGHT AILERON ROD AND HINGES WERE EXAMINED AND THE FAILURES WERE FOUND TO BE SHEAR FROM DUCTILE OVERLOAD. THE FAILED RIVETS MET SPECIFICATIONS FOR HARDNESS TESTS.
