Narrative:

We were vectored for a visual approach to runway 31R at jfk. Winds were approximately 310 degrees at 12 KTS. A 50 degree flap landing was briefed and flown. A normal touchdown was made and the aircraft immediately pitched up. Despite forward pressure on the yoke the aircraft ballooned and became airborne. At the same time we had a bird strike on the nose of the aircraft. A go around was executed to avoid a tail strike. During the missed approach 1500 ft was initially assigned, immediately followed by a heading change and clearance to 2000 ft. During this time we experienced a momentary level 2 alert and numerous questions from ATC about the reason for the go around. The 2000 ft leveloff was overshot by 300-400 ft and an immediate correction was applied. We were vectored again for a visual to runway 31R and a 35 degree flap approach and landing was flown. Landing was normal. The copilot later stated that the spoilers on the first touchdown had gone to full extend instead of 2/3 deployment.

Original NASA ASRS Text

Title: MD11 MAKES GAR JFK AFTER AUTOSPOILER DEPLOYMENT TO FULL INSTEAD OF TWO THIRDS CAUSES PITCH UP.

Narrative: WE WERE VECTORED FOR A VISUAL APCH TO RWY 31R AT JFK. WINDS WERE APPROX 310 DEGS AT 12 KTS. A 50 DEG FLAP LNDG WAS BRIEFED AND FLOWN. A NORMAL TOUCHDOWN WAS MADE AND THE ACFT IMMEDIATELY PITCHED UP. DESPITE FORWARD PRESSURE ON THE YOKE THE ACFT BALLOONED AND BECAME AIRBORNE. AT THE SAME TIME WE HAD A BIRD STRIKE ON THE NOSE OF THE ACFT. A GAR WAS EXECUTED TO AVOID A TAIL STRIKE. DURING THE MISSED APCH 1500 FT WAS INITIALLY ASSIGNED, IMMEDIATELY FOLLOWED BY A HDG CHANGE AND CLRNC TO 2000 FT. DURING THIS TIME WE EXPERIENCED A MOMENTARY LEVEL 2 ALERT AND NUMEROUS QUESTIONS FROM ATC ABOUT THE REASON FOR THE GAR. THE 2000 FT LEVELOFF WAS OVERSHOT BY 300-400 FT AND AN IMMEDIATE CORRECTION WAS APPLIED. WE WERE VECTORED AGAIN FOR A VISUAL TO RWY 31R AND A 35 DEG FLAP APCH AND LNDG WAS FLOWN. LNDG WAS NORMAL. THE COPLT LATER STATED THAT THE SPOILERS ON THE FIRST TOUCHDOWN HAD GONE TO FULL EXTEND INSTEAD OF 2/3 DEPLOYMENT.
