The National Transportation Safety Board is investigating a runway incursion by a United Airlines 777 in Honolulu that occurred on 23 January 2023. The United flight crossed runway 4L in front of a landing Kamaka Air Cessna 208B Super Cargomaster.
Arriving Runway 4L and 4R
United Airlines flight UA384 from Denver touched down in Honolulu on Runway 4R and exited the runway at 02:09:46Z.661 UTC 24 January (16:09 local time 23 Jan) at a speed of 27 knots onto Taxiway K. It crossed the hold short markers for RWY 8L-26R and 4L-22R on Taxiway K at 02:09:53Z.242 traveling 19 knots.
8 seconds prior, Kamaka Air flight 145 had touched down on the parallel Runway 4L and was completing its roll out. At 02:10:00Z.686 United 384 entered the runway area where 8L-26R and 4L-22R intersect Taxiway K at speed of 14 knots, exiting the runway area by 02:10:14Z.708. Note that the physical aircraft size is not represented by the ADS-B data point and coordinates are taken from only a single point on the airframe, so some parts of the aircraft may have been on the runway longer.
At 02:10:08Z.027, when UA384 was in the middle of crossing Runway 4L, KMK145 was decelerating through 44 knots approximately 1/4 of a mile away. The Cessna 208 took an 2 additional seconds to decelerate to 1 knot before turning left onto Taxiway E, then onto Taxiway B.
The aircraft did not come into contact and the NTSB reports no injuries as well.
