One passenger of a Ryanair flight was injured in the leg by a horror when the pilot of the aircraft made a dramatic maneuver to avoid another plane.
The 737 Irish registered flew 37,000 feet above the Canaries when they asked to descend to 13,000 feet.
When it dropped a 1000-foot air traffic control, the crew stopped at 36,000 feet as there was an Easyjet aircraft at 35,000 feet nearby.
A passenger suffered a "broken ankle" during the February 10, 2018 incident, when the pilot deactivated the autopilot to perform the maneuver.
An investigation into a plane crash in Spain, published this week, revealed: "According to the radar data, at 16:38:04, the plane was descending from FL370, the control service had ordered at the control service to stop the descent to FL360 due to a potential conflict with another aircraft.
"A few seconds later, at 16:38:07, according to the data from the flight recorder, the aircraft pilot selected the ALT HOLD mode on the Mode Control Panel (MCP) so to maintain the altitude, a high rate of descent.
"A second later, as the aircraft was flying through FL363, the pilot decided to disengage the autopilot.
"According to his statement, the pilot thought that he had exceeded his authorized flight level of FL360 and, seeing that the recovery maneuver was taking too long, he decided to manually return to the flight level indicated by the air traffic control."
It was at that time that the plane pitched, causing a significant fall of the passenger, who was standing.
A flight attendant who witnessed the injury added, "The injured passenger had a child of about five years in his arms and was coming out of the toilet on the right.
"These sudden movements brought down the four flight attendants.
"The injured passenger turned his body to the left in an attempt to protect the child, which forced his legs into an unnatural position and he broke his ankle as he fell from the jolts.
"The child hit his neck in the head, causing a few bruises, and no one else was hurt.
"After the event, the injured passengers screamed in pain, their loved ones were also upset and raised their voice in front of the flight attendants, complaining about what had happened."
The investigation determined that the injury had been caused by dramatic movements of the pilot when they took control of the aircraft.
"The investigation determined that the accident probably occurred when the crew had performed a sudden manual maneuver to maintain the specified flight level.
"A contributing factor is the disengagement of the autopilot in order to carry out the manual maneuver, which contributed to its abrupt nature."
