После уборки закрылков проблемы с продольным управлением. Минимум семь раз срыв по витку очень похожему на штопор. Первый срыв после набора 10725' с потерей высоты примерно 1500 м, потом активное кувыркание в течение часа. Самый значительный кувырок с потерей высоты 2700 м. Далее очень нестабильный полет до снижения, и обычный полет по глиссаде и посадка.Видно проблемы были серьезными , хотели садиться на воду, но выпустили закрылки и сели без происшествий.

Narrative:
Air Astana flight KC1388 diverted to Beja Airport, Portugal after suffering control issues after departure from Alverca Air Base, Portugal.
The aircraft had arrived at Lisbon on October 2 and underwent maintenance at the OGMA facilities, located at the Alverca Air Base. KC1388 was the first post-maintenance flight. The aircraft took off at 13:31 hours UTC.
Shortly after departure, about 13:34 UTC, the flight issued a Mayday to the Lisbon Approach controller, stating they had control problems. The flight requested to return to Alverca. About 13:37 UTC the flight requested to climb to FL100, again stating they had "flight control problems". At 13:45 the flight requested vectors towards the sea for a ditching.
The aircraft continued to circle to the northeast of Lisbon while requesting vectors from Lisbon Approach towards the sea.
As the aircraft continued circling in the area, two F-16 Fighting Falcon jets of the Portuguese Air Force were scrambled from the Monte Real Air Base. KC1388 was intercepted at 14:48 with an F-16 on the left-hand wing. The F-16 accompanied and guided the flight to Beja Airport (LPBJ) were a landing was carried out about 15:10 UTC.
