Narrative:

We were approaching the FAF, the gear handle was put in the down position by the captain and received a gear unsafe indication. We then consulted the abnormal checklist and performed the failure of 1 or more landing gear indicator checklist. This resulted in a normal indication, followed by a normal landing. Note: the checklist was accomplished after a go around and leveloff at 4000 ft was accomplished. The operation was done in a safe and efficient manner with good crew coordination. Callback conversation with reporter revealed the following information: reporter first officer said that he was not certain if the gear was down or not during the approach into ewr -- he was too busy flying the aircraft. He hadn't felt anything 'special' that would indicate that the gear had actually been up during the unsafe gear indication. He stated that they had reviewed the emergency gear extension checklist but did not use it since the captain simply recycled the gear and it came down in a normal fashion. The aircraft malfunction was written up in the logbook after landing at ewr.

Original NASA ASRS Text

Title: A BE1900 BE02 FO RPT ON A PROB WITH EXTENDING THE GEAR BY NORMAL MEANS WHILE MAKING AN APCH TO EWR. INITIALLY, IT WAS THOUGHT THAT THE GEAR WOULD HAVE TO BE EXTENDED THROUGH THE USE OF THE ABNORMAL CHKLIST.

Narrative: WE WERE APCHING THE FAF, THE GEAR HANDLE WAS PUT IN THE DOWN POS BY THE CAPT AND RECEIVED A GEAR UNSAFE INDICATION. WE THEN CONSULTED THE ABNORMAL CHKLIST AND PERFORMED THE FAILURE OF 1 OR MORE LNDG GEAR INDICATOR CHKLIST. THIS RESULTED IN A NORMAL INDICATION, FOLLOWED BY A NORMAL LNDG. NOTE: THE CHKLIST WAS ACCOMPLISHED AFTER A GAR AND LEVELOFF AT 4000 FT WAS ACCOMPLISHED. THE OP WAS DONE IN A SAFE AND EFFICIENT MANNER WITH GOOD CREW COORD. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR FO SAID THAT HE WAS NOT CERTAIN IF THE GEAR WAS DOWN OR NOT DURING THE APCH INTO EWR -- HE WAS TOO BUSY FLYING THE ACFT. HE HADN'T FELT ANYTHING 'SPECIAL' THAT WOULD INDICATE THAT THE GEAR HAD ACTUALLY BEEN UP DURING THE UNSAFE GEAR INDICATION. HE STATED THAT THEY HAD REVIEWED THE EMER GEAR EXTENSION CHKLIST BUT DID NOT USE IT SINCE THE CAPT SIMPLY RECYCLED THE GEAR AND IT CAME DOWN IN A NORMAL FASHION. THE ACFT MALFUNCTION WAS WRITTEN UP IN THE LOGBOOK AFTER LNDG AT EWR.
