Narrative:

I was the PF, cleared for ILS 16R. Stabilized approach established at 1200 ft AGL with flaps 30. Just before touchdown, I got a balloon effect to 5-8 ft AGL. Captain and first officer came on controls to fly aircraft back down to runway. Landing was soft (not dropped in) about 10 KTS to 20 KTS below target speed. Then, aircraft pitched up noticeably when ground spoilers deployed. This resulted in a scratch to the aft drain mast. Reported to maintenance and wrote up in logbook. Possible cause of pitch up was wind gust combined with higher than usual body angle after balloon on landing. Both captain and first officer pushed control forward at pitch up, but apparently too late to prevent mast scratch.

Title: ACFT DAMAGED SLIGHTLY WHEN DRAIN MAST SCRAPED DURING RECOVERY FROM LNDG PROC.

Narrative: I WAS THE PF, CLRED FOR ILS 16R. STABILIZED APCH ESTABLISHED AT 1200 FT AGL WITH FLAPS 30. JUST BEFORE TOUCHDOWN, I GOT A BALLOON EFFECT TO 5-8 FT AGL. CAPT AND FO CAME ON CTLS TO FLY ACFT BACK DOWN TO RWY. LNDG WAS SOFT (NOT DROPPED IN) ABOUT 10 KTS TO 20 KTS BELOW TARGET SPD. THEN, ACFT PITCHED UP NOTICEABLY WHEN GND SPOILERS DEPLOYED. THIS RESULTED IN A SCRATCH TO THE AFT DRAIN MAST. RPTED TO MAINT AND WROTE UP IN LOGBOOK. POSSIBLE CAUSE OF PITCH UP WAS WIND GUST COMBINED WITH HIGHER THAN USUAL BODY ANGLE AFTER BALLOON ON LNDG. BOTH CAPT AND FO PUSHED CTL FORWARD AT PITCH UP, BUT APPARENTLY TOO LATE TO PREVENT MAST SCRATCH.
