Narrative:
At 2.5 mi from end of runway 13L, jfk airport, the flaps on a B727 were lowered to 30 degrees at approximately 1100 ft AGL. The aircraft had an immediate roll to the right, requiring considerable left wing down input to maintain wings level. There were no cockpit indications of any problem. The gear was down, the runway in sight, the aircraft controllable, so a landing was made. On the ground it was discovered that a 2 ft by 8 ft section of the inner trailing edge flap on the right side had departed the aircraft. Cause unknown.
