A United Airbus A320-200, registration N1902U performing flight
UA-1091 from Mexico City (Mexico) to Houston Intercontinental,TX (USA) with 151 passengers and 6 crew, landed on Houston's runway 27 at 17:27L (22:27Z) but struck its tail onto the runway surface. The aircraft rolled out without further incident and taxied to the apron. There were no injuries, the aircraft sustained substantial damage.
About 90 minutes later the aircraft departed for its next flight climbing to FL340 and performed 7 more sectors until Mar 25th 2023 before being removed from service at Dallas Ft. Worth,TX (USA). The aircraft positioned from Dallas to Houston Intercontinental on Apr 21st 2023 and is on the ground in Houston since (standing Jun 8th 2023).
The NTSB rated the occurrence an accident stating the aircraft sustained substantial damage on landing in Houston due to a tail strike and opened an investigation.
On Jun 21st 2023 the NTSB released their final report concluding the probable cause of the accident was:
The first officer's failure to maintain the correct airspeed and pitch attitude during landing which resulted in a tailstrike.
The NTSB analysed (without going into the 7 flights that followed the accident):
United Airlines flight 1091 sustained a tailstrike while landing at George Bush Intercontinental Airport (KIAH), Houston, TX. The flight was a regularly scheduled international passenger flight from Mexico City, Mexico to KIAH.
According to the flight crew, the captain was the pilot monitoring, and the first officer (FO) was the pilot flying when they were cleared for the visual approach to runway 27 at KIAH. The airplane was in the landing configuration and on a stabilized approach at 1,000 ft. above ground level (AGL). About 60 ft AGL the captain noticed the airspeed begin to decay and stated watch your speed. The FO subsequently pitched the nose of the airplane down and added a little thrust. About 30 ft AGL, due to a higher-than-normal rate of descent the captain commanded flare, flare, flare. The FO flared the airplane which resulted in a firm landing. As the airplane rebounded from the firm landing the spoilers deployed resulting in a nose high attitude. In an effort to correct for the nose high attitude, the captain and FO pushed forward on their respective sidesticks.
The FO stated that the ground spoiler deployment coinciding with the firm touchdown resulted in an airplane nose-up pitch attitude. As a result, the pitch attitude increased until the tail struck the runway. After the tailstrike, the remainder of the landing and landing rollout were normal with no risk of runway overrun or excursion.
The tailstrike resulted in abrasion damage over an area of about 19 feet long by 1 foot wide along the aft lower fuselage. An inspection revealed substantial damage to the aft pressure bulkhead and frames.
