What was found
AFTER TAKEOFF, THE LANDING GEAR TOOK 3 TO 4 TIMES LONGER TO RETRACT THAN NORMAL. CREW RECYCLED THE GEAR AND GOT THE SAME RESULT. WHEN THE GEAR FULLY RETRACTED, THE FLIGHT CONTINUED AND LANDED WITHOUT FURTHER INCIDENT. MAINTENANCE RAISED THE AIRCRAFT AND PERFORMED AN EXTENSION/RETRACTION CHECK. ALL INDICATIONS AND TIME LIMITS WERE NORMAL.
