Narrative:

Engine start was normal. After beginning taxi roll a slight bump was felt that was compatible with a rough ramp area. During taxi a pack malfunction occurred and was eliminated prior to takeoff. During takeoff roll, while passing a runway intersection, a noise was heard from the forward part of the aircraft compatible with runway crossing roughness. Gear retraction and subsequent departure from spi was normal. Flew the rivers 2 arrival to stl. Flight was all normal until gear down on final runway 12R. Nose gear indicator showed red light. Cycled landing gear with red nose gear light still illuminated. Did a flyby of tower. Tower confirmed main gear down, nose gear up. Flight went around. Got radar vector to holding area. Completed gear red/unsafe light(south) illuminated, and manual gear extension checklists with no success. Coordinated with maintenance and boeing and still no success. Flight attendants and passenger briefed on possible emergency landing. Second and third visual gear confirmation made by another aircraft, tower and maintenance on second flyby. Declared emergency. Went back to departure control and coordinated with dispatch/maintenance/flight operations/ATC for emergency landing at blv. Flight attendants were briefed to prepare the cabin for emergency landing. Passenger were briefed on what to expect. Completed the landing with available gear checklist. Discussed the planned after landing evacuate/evacuation with first officer. Was apprised that runway 14L was foamed and ready. Landing was on centerline. Nose touched down at very slow speed. Foam applied to nose area. No fire confirmed by tower and rescue. Engines shut down. Evacuate/evacuation checklist completed. Passenger deplaned with no injury out L1 door. Area secured by rescue. Callback conversation with reporter revealed the following information: the reporter stated the nose gear failure to extend was caused by the spray deflector mounted between the nose gear wheels. The reporter said the deflector evidently was coming off when the gear was retracted and jammed in the nose gear extend mechanism. Callback conversation with reporter on acn 521284 revealed the following information: the reporter stated the nose gear spray deflector was hung up on a shelf and in the extend mechanism.

Title: A B717 ON FINAL HAD NOSE GEAR RED UNSAFE LIGHT DECLARED EMER. LANDED WITH NOSE GEAR RETRACTED. CAUSED BY NOSE GEAR SPRAY DEFLECTOR JAMMED IN NOSE GEAR COMPONENTS.

Narrative: ENG START WAS NORMAL. AFTER BEGINNING TAXI ROLL A SLIGHT BUMP WAS FELT THAT WAS COMPATIBLE WITH A ROUGH RAMP AREA. DURING TAXI A PACK MALFUNCTION OCCURRED AND WAS ELIMINATED PRIOR TO TKOF. DURING TKOF ROLL, WHILE PASSING A RWY INTXN, A NOISE WAS HEARD FROM THE FORWARD PART OF THE ACFT COMPATIBLE WITH RWY XING ROUGHNESS. GEAR RETRACTION AND SUBSEQUENT DEP FROM SPI WAS NORMAL. FLEW THE RIVERS 2 ARR TO STL. FLT WAS ALL NORMAL UNTIL GEAR DOWN ON FINAL RWY 12R. NOSE GEAR INDICATOR SHOWED RED LIGHT. CYCLED LNDG GEAR WITH RED NOSE GEAR LIGHT STILL ILLUMINATED. DID A FLYBY OF TWR. TWR CONFIRMED MAIN GEAR DOWN, NOSE GEAR UP. FLT WENT AROUND. GOT RADAR VECTOR TO HOLDING AREA. COMPLETED GEAR RED/UNSAFE LIGHT(S) ILLUMINATED, AND MANUAL GEAR EXTENSION CHKLISTS WITH NO SUCCESS. COORDINATED WITH MAINT AND BOEING AND STILL NO SUCCESS. FLT ATTENDANTS AND PAX BRIEFED ON POSSIBLE EMER LNDG. SECOND AND THIRD VISUAL GEAR CONFIRMATION MADE BY ANOTHER ACFT, TWR AND MAINT ON SECOND FLYBY. DECLARED EMER. WENT BACK TO DEP CTL AND COORDINATED WITH DISPATCH/MAINT/FLT OPS/ATC FOR EMER LNDG AT BLV. FLT ATTENDANTS WERE BRIEFED TO PREPARE THE CABIN FOR EMER LNDG. PAX WERE BRIEFED ON WHAT TO EXPECT. COMPLETED THE LNDG WITH AVAILABLE GEAR CHKLIST. DISCUSSED THE PLANNED AFTER LNDG EVAC WITH FO. WAS APPRISED THAT RWY 14L WAS FOAMED AND READY. LNDG WAS ON CTRLINE. NOSE TOUCHED DOWN AT VERY SLOW SPD. FOAM APPLIED TO NOSE AREA. NO FIRE CONFIRMED BY TWR AND RESCUE. ENGS SHUT DOWN. EVAC CHKLIST COMPLETED. PAX DEPLANED WITH NO INJURY OUT L1 DOOR. AREA SECURED BY RESCUE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE NOSE GEAR FAILURE TO EXTEND WAS CAUSED BY THE SPRAY DEFLECTOR MOUNTED BTWN THE NOSE GEAR WHEELS. THE RPTR SAID THE DEFLECTOR EVIDENTLY WAS COMING OFF WHEN THE GEAR WAS RETRACTED AND JAMMED IN THE NOSE GEAR EXTEND MECHANISM. CALLBACK CONVERSATION WITH RPTR ON ACN 521284 REVEALED THE FOLLOWING INFO: THE RPTR STATED THE NOSE GEAR SPRAY DEFLECTOR WAS HUNG UP ON A SHELF AND IN THE EXTEND MECHANISM.
