TAIL SKID STRIKE DUE TO NOSE HIGH ATTITUDE ON TOUCHDOWN.

Narrative

WE WERE EXECUTING A VISUAL APCH TO RWY 8 AT SJU. ALL PARAMETERS OF THE APCH WERE NORMAL. SPD AND SINK RATE WERE CONSISTENT WITH A STABILIZED APCH. THRESHOLD XING WAS AT NORMAL HT AND ACFT ALT. AS THE CAPT BEGAN THE FLARE; ALL PARAMETERS APPEARED NORMAL. JUST BEFORE TOUCHDOWN; I NOTICED PITCH ATTITUDE WAS BECOMING SLIGHTLY EXCESSIVE. I CALLED 'BE CAREFUL' AND ALMOST IMMEDIATELY CALLED '12 DEGS' (INDICATING OUR PITCH ATTITUDE). ALMOST IMMEDIATELY WE TOUCHED DOWN. THE TOUCHDOWN FELT COMPLETELY NORMAL. WE COMMENTED THAT ALTHOUGH WE THOUGHT IT WAS PRETTY CLOSE WE WERE GLAD THE TAIL SKID HAD NOT CONTACTED THE RWY. WE WERE LATER ADVISED BY MAINT THAT THE TAIL SKID HAD IN FACT CONTACTED THE RWY. THIS INCIDENT HAPPENED SO RAPIDLY AND SO CLOSE TO THE GND THAT CORRECTIVE ACTION BY THE PF COULD NOT BE TAKEN IN TIME. ALTHOUGH I FELT I RESPONDED CORRECTLY AS THE PNF; PER OUR COMPANY PROCS; I WISH THAT UNDER A SIT WHICH DEVELOPED RAPIDLY; SUCH AS THIS; OUR PROCS WOULD ALLOW OR EVEN ENCOURAGE THE PNF; FO IN THIS CASE; TO PHYSICALLY MANIPULATE THE CTLS TO LOWER THE PITCH ATTITUDE. WHEN IT HAPPENS RAPIDLY THERE IS NOT ENOUGH TIME TO ADVISE THE OTHER PLT; ALLOW HIM TO INTERPRET WHAT WAS SAID AND REACT. AS THE PNF I HAD A BETTER PICTURE OF WHAT WAS OCCURRING WITH RESPECT TO THIS SINGLE ASPECT OF THE FLARE. ALSO; ON ADVANCED ACFT; SUCH AS THE ONE I FLY; A VERBAL WARNING AND/OR A NOSE DOWN INPUT FROM THE FLT COMPUTERS WOULD BE HELPFUL. THIS IS NOT UNREALISTIC IN CONSIDERATION OF THE VARIOUS OTHER WARNINGS AND FLT CTL AUTOMATIC INPUTS ALREADY AVAILABLE TO US. SUPPLEMENTAL INFO FROM ACN 234459: FOLLOWING A NORMAL APCH TO RWY 8; A HIGH SINK RATE WAS NOTED AT THE END OF THE FLARE. THE NOSE WAS RAISED TO ARREST THE SINK AND THE TAIL SKID STRUCK.
