Narrative

AFTER TKOF THE GEAR HANDLE WAS PUT IN THE UP POS AFTER A POSITIVE RATE OF CLB WAS ACCOMPLISHED. WE THEN RECEIVED A GEAR UNSAFE INDICATION. AS WE CLBED OUT AND LEVELED OFF; A XFER OF CTLS WAS MADE FROM CAPT TO FO. WE THEN CONTACTED DISPATCH AND COORDINATED WITH MAINT AND PERFORMED THE LNDG GEAR MANUAL EXTENSION CHKLIST. AT THIS POINT A SAFE GEAR INDICATION WAS RECEIVED AND A NORMAL LNDG WAS MADE BACK AT EWR. THE PAX WERE TAKEN OFF THE ACFT AND THEN WE COORDINATED WITH MAINT TO FERRY THE ACFT BACK TO PLATTSBURGH; NY. THE SIT WAS DEALT WITH IN A PROFESSIONAL; SAFE; AND EFFICIENT MANNER WITH GOOD CREW RESOURCE MGMNT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE ACFT LOGBOOK HAD BEEN FILLED OUT; DESCRIBING THE GEAR PROB. MAINT THEN CHKED THE HYD SYS AND THE GEAR FOR ANY ABNORMALITIES. FINDING NONE; THEY SIGNED OFF THE GEAR WRITE-UP AS 'SYS NORMAL.' AFTER TKOF; THE UNSAFE GEAR INDICATION WAS EVIDENT. THE RPTR SAID THAT THERE IS NO CHKLIST FOR THIS TYPE INDICATION FOR A GEAR RETRACTION PROB. AFTER CONFERRING WITH MAINT; THEY REFERRED AGAIN TO THE EMER EXTENSION CHKLIST BUT; AGAIN; RECYCLING THE GEAR DID PLACE IT IN THE DOWN POS. IT HAD NOT RETRACTED ON TKOF. AFTER ANOTHER GND INSPECTION; THE ACFT WAS FERRIED TO THE MAINT BASE. THERE; THE INSPECTION SPONSORED A WRITE-UP BY MAINT OF 'UNABLE TO DUPLICATE PROB.' THE ACFT WAS THEN RELEASED FOR SVC.
