Narrative:

I was captain/PNF. Our approach was normal and we configured early. Normal callouts were made. I made 2 extra callouts of 'on speed sink 700 down' touchdown was in the touchdown zone. Touchdown was normal as the mains touched. Then as the nose gear was coming down, it pitched up abnormally. The nose gear had not touched down yet. Both my first officer and I pushed forward on the yoke to arrest the pitch-up. The pitch was not excessive, but it was abnormal. There was no danger to the airplane as we both quickly corrected the pitch. The remainder of the flight was uneventful. I believe the problem was with the ground spoilers. There was no bounce or skip. Callback conversation with reporter revealed the following information: the aircraft was returned to the maintenance base where it was determined that a safety wire had not been installed during a maintenance visit allowing linkage to depart the aircraft. The ground spoilers, as a result, only extended partially until engine thrust was reversed commanding full extension and the unexpected pitch up.

Title: B767 PITCH UP ON TOUCHDOWN AS A RESULT OF GND SPOILER PROB.

Narrative: I WAS CAPT/PNF. OUR APCH WAS NORMAL AND WE CONFIGURED EARLY. NORMAL CALLOUTS WERE MADE. I MADE 2 EXTRA CALLOUTS OF 'ON SPD SINK 700 DOWN' TOUCHDOWN WAS IN THE TOUCHDOWN ZONE. TOUCHDOWN WAS NORMAL AS THE MAINS TOUCHED. THEN AS THE NOSE GEAR WAS COMING DOWN, IT PITCHED UP ABNORMALLY. THE NOSE GEAR HAD NOT TOUCHED DOWN YET. BOTH MY FO AND I PUSHED FORWARD ON THE YOKE TO ARREST THE PITCH-UP. THE PITCH WAS NOT EXCESSIVE, BUT IT WAS ABNORMAL. THERE WAS NO DANGER TO THE AIRPLANE AS WE BOTH QUICKLY CORRECTED THE PITCH. THE REMAINDER OF THE FLT WAS UNEVENTFUL. I BELIEVE THE PROB WAS WITH THE GND SPOILERS. THERE WAS NO BOUNCE OR SKIP. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE ACFT WAS RETURNED TO THE MAINT BASE WHERE IT WAS DETERMINED THAT A SAFETY WIRE HAD NOT BEEN INSTALLED DURING A MAINT VISIT ALLOWING LINKAGE TO DEPART THE ACFT. THE GND SPOILERS, AS A RESULT, ONLY EXTENDED PARTIALLY UNTIL ENG THRUST WAS REVERSED COMMANDING FULL EXTENSION AND THE UNEXPECTED PITCH UP.
