ACFT EQUIP PROB. FLC INDUCED GEAR DOWN INDICATION.

Narrative

LNDG GEAR WAS SELECTED DOWN FOR LNDG AT LGA FOLLOWED BY NO GEAR DOWN INDICATION. GAR WAS EXECUTED WITH GEAR LEVER RAISED BUT WOULD NOT MOVE UP PAST THE OFF POS. TWR SAID GEAR APPEARED TO BE DOWN AND WE DEPARTED TFC PATTERN TO RESOLVE PROB. I REQUESTED THAT THE FO CHK ALL CIRCUIT BREAKERS AS BEING IN WHICH HE DID BY MOVING HIS HAND OVER EACH ROW OF CIRCUIT BREAKERS AS I WATCHED HIM. NO TRIPPED BREAKERS WERE FOUND AT THAT TIME. THE EMER GEAR EXTENSION CHKLIST WAS COMPLETED BUT STILL NO GEAR DOWN INDICATION. EMER RESCUE VEHICLES WERE REQUESTED AND STANDING BY. ALL LNDG GEAR WERE VERIFIED DOWN BY VISUAL INSPECTION THROUGH THE VIEWING PORTS. AN ACFT FLYING 1000 FT BELOW US VERIFIED GEAR DOWN AND GEAR DOORS CLOSED. BY THIS TIME; WE WERE DOWN TO A FUEL STATUS OF 4500/5000 LBS OF FUEL. SWITCHED OVER TO TWR FOR LNDG AND WERE ADVISED THAT THE PORT AUTH REQUESTED ANOTHER FLYBY BEFORE LNDG. WE AGREED AND EXECUTED THE MISSED APCH AND WERE SWITCHED OVER TO DEP CTL. THEY PLANNED TO VECTOR US OUT TO A 15 MI FINAL FOR TFC. THAT WOULD HAVE FORCED US TO USE OUR RESERVE FUEL SO WE DECLARED AN EMER. ARRIVED AT THE GATE WITH 3900 LBS FUEL. ON FINAL WHEN FLAPS WERE SELECTED FOR LNDG THE GEAR WARNING HORN SOUNDED. I REQUESTED THE FO PULL THE GEAR WARNING CIRCUIT BREAKER. WHEN HE LOOKED BACK HE SAW THAT THE GEAR 'AIR/GND RELAY AND LIGHTS' CIRCUIT BREAKER WAS TRIPPED. UPON RESET; NORMAL GEAR INDICATION WAS OBSERVED. TWR WAS NOTIFIED THAT AFTER LNDG; WE WOULD CLR THE RWY AND STOP TO HAVE OUR GEAR PINNED. UPON CLRING THE RWY; A POLICE CAR PULLED IN FRONT OF US AND STOPPED ON THE TXWY BROADSIDE TO BLOCK US. I THINK THE PORT AUTH IS GETTING A LITTLE TOO BOLD IN DIRECTING US TO FLYBY AND THEN BLOCK AN ACFT THAT IS MOVING AND ACT AS THOUGH WE ARE CRIMINALS. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: AFTER THE FIRST GAR; TWR OBSERVED THE GEAR DOWN; BUT FLC CONTINUED TO A HOLDING PATTERN TO TROUBLE-SHOOT AND COMPLETE CHKLISTS. WHEN RETURNING FOR LNDG; TWR TOLD RPTR THAT THE PORT AUTH REQUIRED ANOTHER GAR IN ORDER TO VERIFY THAT THE GEAR WAS DOWN. RPTR COMPLIED AND WHEN SWITCHING TO DEP CTL WAS TOLD; DUE TO TFC SEQUENCING HE WOULD BE SET UP ON A 15 MI FINAL. RPTR CAPT; APPARENTLY CONCERNED ABOUT BURNING CONTINGENCY FUEL; WOULD NOT ACCEPT THE LONG FINAL AND DECLARED AN EMER. HE WAS THEN GIVEN PRIORITY HANDLING AND LANDED UNEVENTFULLY. HOWEVER; AFTER CLRING THE RWY AFTER LNDG; AND WAITING FOR GEAR PINS TO BE INSTALLED. A PORT AUTH POLICE CAR BLOCKED HIS TXWY UNTIL AFTER THE GEAR PINS WERE INSTALLED. RPTR THINKS THAT THE PORT AUTH IS DELVING INTO AREAS OUTSIDE OF THEIR JURISDICTION.
