A replacement A21N registration CS-TJK reached Lisbon with a delay of about 8:10 hours.
A passenger reported they had been only informed about a "technical issue" with the aircraft.
The aircraft is still on the ground in Barcelona about 25 hours after landing.
On Nov 8th 2023 Portugal's GPIAA reported ECAM "ENG2 SHUTDOWN" was triggered when the aircraft was overflying BCN VOR at FL370. The engine failure checklists were worked and the crew diverted the aircraft to Barcelona. The occurrence was rated a serious incident and is being investigated by the GPIAA.
On Jan 4th 2024 the GPIAA added, that the crew determined there was no engine damage and attempted to relight the engine twice without success. After landing and while executing the parking procedures the crew noticed that the #2 engine fire push button had popped out and its guard was open. The fire panel was replaced and the aircraft returned to service. The occurrence is being investigated rated as serious incident.
On Dec 20th 2024 the GPIAA released their final report concluding the probable causes of the serious incident were:
Based on the information from examination of the aircraft components and analysis of the flight data, the investigation points to the failure of the PB-SW retaining pin of the respective engine as the most likely cause for the uncommanded in-flight shutdown of engine #2.
For the pin failure will have contributed:
- Improper handling of the panel with probable drop prior to June 2013, causing internal damage to the fire PB-SW retaining pin and creating a latent condition for the release of the handle and consequent uncommanded engine shutdown,
- Improper panel repair process carried out by the-OEM, after damage due to probable drop, by not detecting or foreseeing in the applicable manuals, possible damage and/or deformations to the switch retaining pin,
- Design of the switch retaining system without redundancy and with manufacturing tolerances that allowed a small deformation of the pin (bent by
