What was found
THE INITIAL SQUAWK WAS FOR THE FLAP ACTUATORS NOT LOCKING IN THE FULLY RETRACTED POSITION. THE FLAPS WOULD DROOP DURING TAXI AND/OR WHILE PARKED. DURING THE SERVICE EVENT. THE TECHNICIANS REPORTED THE FLAP ACTUATORS WERE UNLOCKING AT DIFFERENT PRESSURES. THIS WOULD CAUSE A MOMENTARY ASYMMETRIC DEPLOYMENT OF THE FLAPS. TEXTRON ENGINEERING DIRECTED THE THE TECHNICIANS TO REPLACE BOTH FLAP ACTUATORS. AS A PRECAUTION, WE REQUESTED THE FLAP ACTUATORS FROM THE 525B BE INSTALLED RATHER THAN THE NEWER ACTUATORS FROM THE 525B+. ACCORDING TO THE TEXTRON IPC THESE ACTUATORS ARE INTERCHANGEABLE AS LONG AS BOTH LH AND RH ACTUATORS ARE THE SAME PART NUMBER. APPROXIMATELY 5 FLIGHTS HAVE BEEN CONDUCTED WITH NO SIGN OF THE ISSUE RETURNING.
