What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
As the aircraft approached the Portland airport (pwm) for landing on runway 18, the crew conducted their landing flows and noticed a gear unsafe warning indication with two green down and locked indicator lights for the left and right main landing gear. The crew conducted a go-around to troubleshoot the issue and Portland tower advised the aircraft it appeared as though the nose landing gear was still retracted. The flight crew completed all applicable checklists, to include utilizing the landing gear?s ?blow down? Bottle to extend the landing gear. The gear unsafe indication remained and the flight crew declared an emergency and conducted an emergency landing on runway 18 without the nose landing gear extended. The aircraft came to a stop on the runway and the two passengers were evacuated on the runway. The flight crew and passengers did not sustain any injuries during the landing and subsequent evacuation. An inspection of the aircraft revealed the right nose landing gear door was jammed against the nose landing gear in a position into the landing gear well, beyond the point the landing gear door would normally close. This jammed the nose landing gear in the retracted position and prevented its extension. Once the nose landing gear was extended by maintenance personnel, the nose landing gear retraction spring was found to have failed. privacy data omitted Maintenance stated with this spring broken, there is enough play in the nose landing gear doors for the doors to make contact with the nose landing gear wheel during the retraction sequence.
As the FAA filed it
AS THE AIRCRAFT APPROACHED THE PORTLAND AIRPORT (PWM) FOR LANDING ON RUNWAY 18, THE CREW CONDUCTED THEIR LANDING FLOWS AND NOTICED A GEAR UNSAFE WARNING INDICATION WITH TWO GREEN DOWN AND LOCKED INDICATOR LIGHTS FOR THE LEFT AND RIGHT MAIN LANDING GEAR. THE CREW CONDUCTED A GO-AROUND TO TROUBLESHOOT THE ISSUE AND PORTLAND TOWER ADVISED THE AIRCRAFT IT APPEARED AS THOUGH THE NOSE LANDING GEAR WAS STILL RETRACTED. THE FLIGHT CREW COMPLETED ALL APPLICABLE CHECKLISTS, TO INCLUDE UTILIZING THE LANDING GEAR?S ?BLOW DOWN? BOTTLE TO EXTEND THE LANDING GEAR. THE GEAR UNSAFE INDICATION REMAINED AND THE FLIGHT CREW DECLARED AN EMERGENCY AND CONDUCTED AN EMERGENCY LANDING ON RUNWAY 18 WITHOUT THE NOSE LANDING GEAR EXTENDED. THE AIRCRAFT CAME TO A STOP ON THE RUNWAY AND THE TWO PASSENGERS WERE EVACUATED ON THE RUNWAY. THE FLIGHT CREW AND PASSENGERS DID NOT SUSTAIN ANY INJURIES DURING THE LANDING AND SUBSEQUENT EVACUATION. AN INSPECTION OF THE AIRCRAFT REVEALED THE RIGHT NOSE LANDING GEAR DOOR WAS JAMMED AGAINST THE NOSE LANDING GEAR IN A POSITION INTO THE LANDING GEAR WELL, BEYOND THE POINT THE LANDING GEAR DOOR WOULD NORMALLY CLOSE. THIS JAMMED THE NOSE LANDING GEAR IN THE RETRACTED POSITION AND PREVENTED ITS EXTENSION. ONCE THE NOSE LANDING GEAR WAS EXTENDED BY MAINTENANCE PERSONNEL, THE NOSE LANDING GEAR RETRACTION SPRING WAS FOUND TO HAVE FAILED. ^PRIVACY DATA OMITTED^ MAINTENANCE STATED WITH THIS SPRING BROKEN, THERE IS ENOUGH PLAY IN THE NOSE LANDING GEAR DOORS FOR THE DOORS TO MAKE CONTACT WITH THE NOSE LANDING GEAR WHEEL DURING THE RETRACTION SEQUENCE.
