This was confirmed in a statement by the airline on Facebook with an explanation of what occurred. The aircraft had to return to Lagos and passengers were transferred to another aircraft.
The statement read:
On 21st of April, one of our aircraft with registration number 5N-SRI operating our 11am flight from Lagos to Port Harcourt, had an air return due Birdstrike during take-off from Lagos, and our Captain took a professional decision and returned to the Lagos Airport.
A Bird strike is a collision between a bird and an aircraft which is airborne and as per standard safety procedure, which is the hallmark of our operation, our pilot returned to base.
Our guests have however been reprotected on another aircraft to ensure that their itinerary is not entirely disrupted. The aircraft is currently being evaluated by our engineers to determine the effect of the bird strike on the affected engine.
At Dana Air, the safety and comfort of our guests will remain a top priority to us and we will stop at nothing in our commitment towards offering a safe and reliable air transport.
This is coming 3 days after an Aero Contractors flight from Port Harcourt to Lagos was filled with smoke. One of the passengers on the flight shared a video of the incident.
