What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
On April 11, 2024, a Boeing 747-8F deflated six (6) main left gear tires after landing in Anchorage, Alaska (anc). The flight was operated by a flight crew of four (4), two (2) captains (CA), one (1) on operational experience (oe) training acting as pilot flying (pf), a company line check pilot (lcp) acting as the pilot monitoring (pm) and two (2) first officers (fo) acting as relief pilots.
One (1) hour prior to arrival at anc. The flight
Crew requested landing performance data from privacy data omitted, using winds of 190 degrees at eight (8) knots for winds in anc. Flaps 30 was selected for landing, and the flight crew briefed using autobrakes three (3) for landing. The metars for anc just prior to landing at 13:18 zulu reported winds of 210 degrees at 10 knots.
Upon touchdown thrust reverse was engaged for the number two (2), three (3), and four (4) engines. The #1 engine thrust reverse was not engaged; thrust was increased on the number one (1) engine to approximately 60 percent N1. The engines remained in this configuration for the entire landing rollout.
The speedbrakes automatically deployed and then immediately stowed. The lcp then reported that the left wing had started to rise and told the oe CA to level the wings. The flight crew reported hearing the autobrakes click off and reverted to manual braking. The flight crew was unaware that the number one (1) engine was not in reverse thrust and likely utilized differential braking to maintain the centerline.
After decelerating on the runway centerline, they taxied off the runway at taxiway charlie (c). The thrust reversers were stowed, and the flight crew realized the number one (1) engine was not in reverse thrust.
On taxiway kilo (k), the flight crew then received a brake temperature engines indication and crew alerting system (eicas) message and ran the quick reference handbook (qrh) after coming to a stop. Airport fire rescue (ARFF) was called as a precaution.
Six (6) fuse plugs melted and deflated those tires. As a result, the aircraft remained on the taxiway until company maintenance could change the tires and tow the aircraft to the
Parking stand.
As the FAA filed it
ON APRIL 11, 2024, A BOEING 747-8F DEFLATED SIX (6) MAIN LEFT GEAR TIRES AFTER LANDING IN ANCHORAGE, ALASKA (ANC). THE FLIGHT WAS OPERATED BY A FLIGHT CREW OF FOUR (4), TWO (2) CAPTAINS (CA), ONE (1) ON OPERATIONAL EXPERIENCE (OE) TRAINING ACTING AS PILOT FLYING (PF), A COMPANY LINE CHECK PILOT (LCP) ACTING AS THE PILOT MONITORING (PM) AND TWO (2) FIRST OFFICERS (FO) ACTING AS RELIEF PILOTS.
ONE (1) HOUR PRIOR TO ARRIVAL AT ANC. THE FLIGHT
CREW REQUESTED LANDING PERFORMANCE DATA FROM ^PRIVACY DATA OMITTED^, USING WINDS OF 190 DEGREES AT EIGHT (8) KNOTS FOR WINDS IN ANC. FLAPS 30 WAS SELECTED FOR LANDING, AND THE FLIGHT CREW BRIEFED USING AUTOBRAKES THREE (3) FOR LANDING. THE METARS FOR ANC JUST PRIOR TO LANDING AT 13:18 ZULU REPORTED WINDS OF 210 DEGREES AT 10 KNOTS.
UPON TOUCHDOWN THRUST REVERSE WAS ENGAGED FOR THE NUMBER TWO (2), THREE (3), AND FOUR (4) ENGINES. THE #1 ENGINE THRUST REVERSE WAS NOT ENGAGED; THRUST WAS INCREASED ON THE NUMBER ONE (1) ENGINE TO APPROXIMATELY 60 PERCENT N1. THE ENGINES REMAINED IN THIS CONFIGURATION FOR THE ENTIRE LANDING ROLLOUT.
THE SPEEDBRAKES AUTOMATICALLY DEPLOYED AND THEN IMMEDIATELY STOWED. THE LCP THEN REPORTED THAT THE LEFT WING HAD STARTED TO RISE AND TOLD THE OE CA TO LEVEL THE WINGS. THE FLIGHT CREW REPORTED HEARING THE AUTOBRAKES CLICK OFF AND REVERTED TO MANUAL BRAKING. THE FLIGHT CREW WAS UNAWARE THAT THE NUMBER ONE (1) ENGINE WAS NOT IN REVERSE THRUST AND LIKELY UTILIZED DIFFERENTIAL BRAKING TO MAINTAIN THE CENTERLINE.
AFTER DECELERATING ON THE RUNWAY CENTERLINE, THEY TAXIED OFF THE RUNWAY AT TAXIWAY CHARLIE (C). THE THRUST REVERSERS WERE STOWED, AND THE FLIGHT CREW REALIZED THE NUMBER ONE (1) ENGINE WAS NOT IN REVERSE THRUST.
ON TAXIWAY KILO (K), THE FLIGHT CREW THEN RECEIVED A BRAKE TEMPERATURE ENGINES INDICATION AND CREW ALERTING SYSTEM (EICAS) MESSAGE AND RAN THE QUICK REFERENCE HANDBOOK (QRH) AFTER COMING TO A STOP. AIRPORT FIRE RESCUE (ARFF) WAS CALLED AS A PRECAUTION.
SIX (6) FUSE PLUGS MELTED AND DEFLATED THOSE TIRES. AS A RESULT, THE AIRCRAFT REMAINED ON THE TAXIWAY UNTIL COMPANY MAINTENANCE COULD CHANGE THE TIRES AND TOW THE AIRCRAFT TO THE
PARKING STAND.
