Narrative:
A B747-400 aircraft was released for departure with two MEL items. Number 1 pack was 'inoperative' and number 4 flap canoe fairing had been removed from the aircraft. Made stabilized approach to runway-15 and landed in the touchdown zone with a flap setting of 25. The post-flight walk-around inspection was performed by captain Y. He discovered a flap control rod protruding a few inches from the top of the number 3 flap canoe fairing. Captain X brought this to my attention and I made a personal inspection. In turn; I brought this circumstance to the attention of contract maintenance personnel. After contract mechanic performed his initial inspection; he decided to electrically lower the flaps for a more comprehensive inspection. His immediate assessment was damage of unknown origin to flap control rods on number 3 and number 4 flap track assemblies. I made a maintenance logbook entry; identifying the initial discovery made during the post-flight walk-around inspection of the aircraft. I believe voluntary removal of aircraft fairings and/or related protective equipment is not a good scenario.
