From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(.19)On February 5, 1999, about 1110 Alaska standard time, a Mcdonnell Douglas MD-82 airplane, N934AS, had a partial flight control malfunction during takeoff from the Fairbanks International Airport, Fairbanks, Alaska. The flight was being conducted under title 14, CFR part 121, as a scheduled domestic passenger flight, operated by Alaska airlines, inc., as flight 82. There were no injuries to the two pilots, three flight attendants, or the 133 passengers aboard. Instrument meteorological conditions prevailed, and an instument flight plan had been filed for the flight to anchorage, Alaska. During an interview with the national transportation safety board (NTSB) investigator-in-charge on February 5, the captain stated that during the takeoff roll, the airplane's nose failed to rise as he applied aft control yoke pressure. He stated that when he applied an excessive amount of aft control yoke pressure, the nose rotated slowly, and the airplane assumed the desired pitch angle for takeoff. He said that after he was assured that a positive rate of climb had been established, he declared an in-flight emergency, and continued on to anchorage for an emergency landing. The captain said that during the approach and landing in anchorage, the elevator control felt "sluggish and slow to respond to control inputs." After landing, the airplane was taxied to the gate, and all 138 of the occupants disembarked uneventfully. Fairbanks International Airport weather observation at the time of the incident consisted of: sky conditions and ceiling, 400 feet broken, 2,000 feet overcast; visibility, 1/2 statute mile; wind, calm; temperature, minus 47 degrees f. (.4).4 narrative same as .19 narrative (-23)a DC-9/82 airplane had a partial elevator control malfunction during takeoff from Fairbanks int'l airport. The temperature was minus 47 degress f. the airplane proceeded to anchorage int'l airport where a similar problem occurred during landing. During the takeoff roll at fai, the nose failed to rise until an excessive amount of aft control yoke pressure was applied, whereon the nose rotated slowly and assumed the desired pitch for climb. During approach and landing at anc, the elevator control felt sluggish and slow to respond to control inputs. The log stated the elevator was "pum p" to flare for landing.

As the FAA filed it

(.19)ON FEBRUARY 5, 1999, ABOUT 1110 ALASKA STANDARD TIME, A MCDONNELL DOUGLAS MD-82 AIRPLANE, N934AS, HAD A PARTIAL FLIGHT CONTROL MALFUNCTION DURING TAKEOFF FROM THE FAIRBANKS INTERNATIONAL AIRPORT, FAIRBANKS, ALASKA. THE FLIGHT WAS BEING CONDUCTED UNDER TITLE 14, CFR PART 121, AS A SCHEDULED DOMESTIC PASSENGER FLIGHT, OPERATED BY ALASKA AIRLINES, INC., AS FLIGHT 82. THERE WERE NO INJURIES TO THE TWO PILOTS, THREE FLIGHT ATTENDANTS, OR THE 133 PASSENGERS ABOARD. INSTRUMENT METEOROLOGICAL CONDITIONS PREVAILED, AND AN INSTUMENT FLIGHT PLAN HAD BEEN FILED FOR THE FLIGHT TO ANCHORAGE, ALASKA. DURING AN INTERVIEW WITH THE NATIONAL TRANSPORTATION SAFETY BOARD (NTSB) INVESTIGATOR-IN-CHARGE ON FEBRUARY 5, THE CAPTAIN STATED THAT DURING THE TAKEOFF ROLL, THE AIRPLANE'S NOSE FAILED TO RISE AS HE APPLIED AFT CONTROL YOKE PRESSURE. HE STATED THAT WHEN HE APPLIED AN EXCESSIVE AMOUNT OF AFT CONTROL YOKE PRESSURE, THE NOSE ROTATED SLOWLY, AND THE AIRPLANE ASSUMED THE DESIRED PITCH ANGLE FOR TAKEOFF. HE SAID THAT AFTER HE WAS ASSURED THAT A POSITIVE RATE OF CLIMB HAD BEEN ESTABLISHED, HE DECLARED AN IN-FLIGHT EMERGENCY, AND CONTINUED ON TO ANCHORAGE FOR AN EMERGENCY LANDING. THE CAPTAIN SAID THAT DURING THE APPROACH AND LANDING IN ANCHORAGE, THE ELEVATOR CONTROL FELT "SLUGGISH AND SLOW TO RESPOND TO CONTROL INPUTS." AFTER LANDING, THE AIRPLANE WAS TAXIED TO THE GATE, AND ALL 138 OF THE OCCUPANTS DISEMBARKED UNEVENTFULLY. FAIRBANKS INTERNATIONAL AIRPORT WEATHER OBSERVATION AT THE TIME OF THE INCIDENT CONSISTED OF: SKY CONDITIONS AND CEILING, 400 FEET BROKEN, 2,000 FEET OVERCAST; VISIBILITY, 1/2 STATUTE MILE; WIND, CALM; TEMPERATURE, MINUS 47 DEGREES F. (.4).4 NARRATIVE SAME AS .19 NARRATIVE (-23)A DC-9/82 AIRPLANE HAD A PARTIAL ELEVATOR CONTROL MALFUNCTION DURING TAKEOFF FROM FAIRBANKS INT'L AIRPORT. THE TEMPERATURE WAS MINUS 47 DEGRESS F. THE AIRPLANE PROCEEDED TO ANCHORAGE INT'L AIRPORT WHERE A SIMILAR PROBLEM OCCURRED DURING LANDING. DURING THE TAKEOFF ROLL AT FAI, THE NOSE FAILED TO RISE UNTIL AN EXCESSIVE AMOUNT OF AFT CONTROL YOKE PRESSURE WAS APPLIED, WHEREON THE NOSE ROTATED SLOWLY AND ASSUMED THE DESIRED PITCH FOR CLIMB. DURING APPROACH AND LANDING AT ANC, THE ELEVATOR CONTROL FELT SLUGGISH AND SLOW TO RESPOND TO CONTROL INPUTS. THE LOG STATED THE ELEVATOR WAS "PUM P" TO FLARE FOR LANDING.
