On 17 September, a United Airlines Boeing 737-900ER (registered N78448) operated a domestic flight between Los Angeles and Lewiston, United States. During disembarkation and unloading of the aircraft, however, the aircraft tipped onto its tail.
As the incident occurred during disembarkation, the most likely cause of this tail tipping is an improper balance with many passengers still seated/standing in the rear of the aircraft.
