The Air Accident Investigation Unit has concluded its inquiry into a bird-strike incident at Ireland West Airport (EIKN) in 2009.
A Boeing 737 on route to Manchester at the time, sustained damage to two of its engines, after it hit a flock of lapwings.
Investigators have found FDR data that suggests that the multiple bird strikes happened right after the flight took off from Runway 9 at EIKN.
The BMI baby plane had 127 passengers and five crew members on board and was diverted to Shannon airport.
Four bird patrols had been carried out during the morning of the incident with no subsequent reports of bird activity on the aerodrome. But AAIU cited that no bird patrol took place just before take-off.
The plane's No 1 engine suffered bending and distortion damage to several of its fan blades, while the No 2 engine lost its nacelle fan-duct acoustic panel.
