CE560 CAPT MISSETS ALTIMETER BY ONE INCH MERCURY ON DEP FROM TEB.

Narrative

DURING DEP ON RWY 24 PERFORMING THE TEB5 DEP; WE RECEIVED A LOW ALT WARNING FROM THE TAWS. AFTER CHK WITH DEP; IT WAS DETERMINED THAT OUR ALT WAS LOWER THAN WHAT WAS INDICATED ON THE ALTIMETER. AFTER A QUICK CROSS CHK OF ALTIMETERS; IT WAS DETERMINED THAT THE CAPT'S ALTIMETER WAS SET LOWER THAN THE COPLT'S. A CLB WAS INITIATED AND ALTIMETERS CORRECTED. THE SITUATION WAS CAUSED BY THE CAPT PUTTING IN THE WRONG ALTIMETER SETTING. AT THE TIME THE SETTING WAS SET (BY ME) THE CAPT COMMENTED THAT IT APPEARED TO BE A VERY LOW SETTING. THE COPLT SAID YES IT WAS. TO AVOID THE PROB IN THE FUTURE; THE UNIT SOP HAS TO BE REVISED TO REPEATING THE ALTIMETER TWICE AND ASSURING ALL ALTIMETERS ARE SET TO THE PROPER SETTING.SUPPLEMENTAL INFO FROM ACN 723177: WHILE CAPT (PF) WAS OCCUPIED WITH DUTIES OUTSIDE THE ACFT; I (PNF) WENT TO THE ACFT TO OBTAIN THE IFR CLRNC AND ATIS INFO. AFTER OBTAINING BOTH; I SET THE CURRENT ALTIMETER SETTING IN THE COPLT STANDBY BAROMETRIC ALTIMETER; BUT NEGLECTED TO SET IT IN THE COPLT'S MAIN ALTIMETER. WHEN THE CAPT ARRIVED IN THE ACFT; I BRIEFED HIM ON THE CURRENT ATIS INFO -- INCLUDING ALTIMETER SETTING -- AND HE ACKNOWLEDGED. THE CAPT SET IN AN ERRONEOUS ALTIMETER SETTING IN HIS ALTIMETER; AND I WAS REMISS IN CROSS CHKING; NOT ONLY HIS SETTING BUT THE SETTING IN THE COPLT'S PRIMARY ALTIMETER. AFTER TKOF FROM RWY 24; THE PF ALTIMETER INDICATED HE WAS TOO HIGH FOR THE DEP; AND BEGAN CORRECTIVE ACTION TO COMPLY WITH TEB 5 DEP ALT RESTRICTIONS (1500 FT). HE BEGAN DSCNT TO THE CALLED FOR ALT; RESULTING IN A GPWS ALERT AND A CALL FROM NY DEP CTL INQUIRING ABOUT OUR LOW ALT. A CLB WAS INITIATED IMMEDIATELY. THE COCKPIT ALTIMETER SETTING ERROR WAS IMMEDIATELY CORRECTED AND THE FLT PROCEEDED UNEVENTFULLY TO ITS DEST. THE PROBLEM AROSE AS A RESULT OF THE PNF'S UNFAMILIARITY WITH THIS PARTICULAR ACFT AND THE LOCAL AREA. LOCAL PROCS HAVE BEEN IMPLEMENTED TO PREVENT A REOCCURRENCE; AND ENSURE PROPER COCKPIT CROSS CHKING.CALLBACK CONVERSATION WITH RPTR ACN 723177 REVEALED THE FOLLOWING INFO: THE RPTR STATES THAT HE IS FAIRLY NEW TO THIS MODEL CITATION AND DID NOT PERFORM SOME CROSS CHKS THAT HE WOULD NORMALLY PERFORM. THE CAPT ACTUALLY SET HIS ALTIMETER ONE INCH HIGH; WHICH WENT UNDETECTED UNTIL AIRBORNE.
