Incident Overview
On Friday, February 26, 2016, at 1548 Hawaii standard time, a runway incursion occurred at Honolulu International Airport (HNL), Honolulu, Hawaii. N865MA, a Cessna 208B (C208B), overflew N269ME, a Cessna 172 (C172S), during a line up and wait (LUAW) operation on runway 22L at the intersection of taxiway P. The C208B, registered to Schuman Aviation Company, was operating as KDS (Kaleo) 1535, a single-pilot 14 Code of Federal Regulations Part 135 scheduled air charter from Molokai to HNL with 9 passengers. The C172S was operating under Part 91 as a Georges Aviation Services flight school aircraft based at HNL. Visual meteorological conditions prevailed, and there were no injuries to passengers or crew of either aircraft.
Sequence of Events
Approximately 4 minutes before the C208B was cleared to land on runway 22L, the HNL local controller (LC) instructed the C172S to LUAW on runway 22L at the intersection of taxiway P. No traffic advisories were issued to the C172S pilot. The controller later stated that the C172S was placed in LUAW due to conflicting arriving traffic to runway 26L and other traffic in the tower pattern.
At 1545:48, the LC instructed the pilot of Kaleo 1535 (C208B) to continue for runway 22 right and advised of traffic departing runway 26 right. The pilot acknowledged. At 1547:25, the LC instructed the C208B to turn inbound and land beyond the intersection on runway 22 left, clearing it to land. The pilot acknowledged.
At 1548:02, the LC instructed an Air Force KC-135 holding short of runway 26R to cross runway 26 right with no delay. At 1548:23, the LC instructed a Delta flight to contact departure. At 1548:26, after the C208B had crossed the landing threshold of runway 22L, the LC issued a go-around instruction to Kaleo 1535 due to an alarm from the airport surface detection equipment, model X (ASDE-X), indicating a conflict. The C208B overflew the C172S in position on the runway. The vertical proximity between the two aircraft was less than 100 feet. The pilot of Kaleo 1535 acknowledged and was instructed to make right traffic for runway 22 right.
At 1549:35, the LC cleared the pilot of N269ME for takeoff from runway 22 left at the intersection of taxiway P.
Air Traffic Control Communications
The airport was operating with runways 22 left and right and runways 26 left and right in use, a non-standard configuration occurring approximately 10% of the time. The LC managed multiple aircraft, including an ATR 72 in LUAW on runway 26R, a Boeing 767 crossing runway 26R, a Boeing 757 in LUAW on runway 26R, a helicopter inbound between runways, a departing aircraft, an arriving KC-135, and Delta flights. Communications included instructions for LUAW, takeoffs, landings, and taxi routes.
