diving sharply. The crew activated the direct mode for flight controls which allowed sufficient control to make an emergency landing on the third attempt at Beja Airbase in Portugal with serious damage sustained during these high-G maneuvers. It was subsequently written-off and broken up. The investigation revealed that the aileron cables were installed incorrectly, causing reversal of aileron controls. The investigation blamed the manufacturer of the airplane for the poorly written maintenance instructions, the supervising authorities for lack of oversight over the maintenance crew, who lacked the skill to perform the maintenance, and the flight crew for failing to notice the condition during pre-flight control checks. Other incidents On 18 February 2007, Shuttle America Flight 6448 (an E170 operating for Delta Connection) ran off the runway on landing at Cleveland Hopkins International Airport in poor visibility during a snowstorm. None of the 75 passengers and crew aboard were injured, and the aircraft, while significantly damaged, was repaired and returned to service. On 4 December 2016, SkyWest Airlines flight 5588, an E175 operating as a United Express flight from Houston Intercontinental Airport to Monterrey, Mexico, was diverted to San Antonio International Airport after experiencing an abnormal landing gear indication. Upon landing, the nose gear of the aircraft collapsed, and the aircraft came to rest on runway 04. Of the 51 passengers and 4 crew members, only one minor injury was sustained during the evacuation. During recovery of the aircraft, it was discovered that a failed downlock spring on the nose gear had prevented the landing gear from locking in the down position. On 12 May 2019, Myanmar National Airlines E190 flight UB-103 to Mandalay, Myanmar had to land without the nosewheel, which failed to deploy. There were no casualties reported among the 82 passengers and seven crew. On 6 November 2019, a Republic Airways E175 operating American Eagle Flight 4439 returned to Atlanta Hartsfield-Jackson International Airport after suffering severe controllability issues after takeoff: ATC flight data recorded the crew stating a "trim runaway" and a "stalling situation". The data shows the aircraft rapidly climbing to , slowing down to , while performing nearly two full right turns. Specifications See also Notes References Citations Bibliography Eden, Paul E.
