A United Boeing 737-900, registration N62883 performing flight UA-2498 from Phoenix,AZ to Houston Intercontinental,TX (USA) with 179 passengers and 6 crew, landed on Houston's runway 27 but touched down hard at about 1.87G at 6.5 degrees nose up, bounced touching down a second time at about 2.87G at 7.2 degrees nose up, bounced briefly another time before settling on the runway, rolling out and taxiing to the terminal. The crew remained unaware of a tail strike until ground staff told them about the damage.

The aircraft remained on the ground in Houston until May 7th 2024, then positioned to Chicago Rockford,IL (USA) and still on the ground in Rockford 11 days after landing in Rockford.

On May 18th 2024 the NTSB released their final report and their investigation docket concluding the probable cause of the accident was:

The airplane’s aft fuselage impacted the runway as a result of a delayed flare and subsequent nose-high pitch inputs during the aircraft’s multiple touchdowns.

The NTSB analysed:

United Airlines flight 2498 experienced a tail strike while landing at George Bush Houston Intercontinental Airport (IAH), Houston, Texas. The flight was a regularly scheduled domestic passenger flight from Phoenix Sky Harbor Airport (PHX), Phoenix, Arizona to IAH.

The flight crew statements and flight data showed a stable approach to the landing flare. The first officer was pilot flying and stated he began the flare slightly late. Both crewmembers stated the touchdown was firm with a slight “nose-high” bounce. The flight crew was not aware the airplane’s tail had impacted the runway until the ground crew at the gate notified them.

Flight data showed that the airplane touched down on the runway with a 6.5-degree nose-up attitude and vertical acceleration of 1.87g. The speed brakes deployed two seconds after the initial touchdown. At the same time, the aircraft became airborne again and the nose began to lower. Two seconds later, as the speed brakes retracted, the airplane’s pitch began to increase, and the airplane touched down a second time with pitch of 7.2 degrees and a vertical acceleration of about 2.87g. The airplane became airborne for a 3rd time for about a second before it touched down for the final time. The nose was lowered to the ground, and speed brakes were extended again.

Post-accident assessment of the aircraft revealed substantial damage to the auxiliary power unit (APU) firewall bulkhead that occurred as a result of the aircraft’s aft fuselage’s contact with the runway.
