Investigators are treating the crash of American Airlines Flight 578 as an accident, with evidence pointing to mechanical failure in the twin-engine Airbus A300.
The CF6-80C2 engines that powered the aircraft and more than 1,000 others worldwide, have been closely scrutinised by federal safety officials since the spring of 2000.
After extensive review, the Federal Aviation Administration published a notice last month stating there was a "need for mandatory inspections" of the engine because "an unsafe condition has been identified".
General Electric, the parent company for the engine maker, said it complied with all the repair orders and believed the engine was "phenomenally reliable". GE has built 2,954 of these engines which were first introduced in 1984.
Earlier this year, a problem with the same type of engine forced the emergency landing of a Monarch Airlines passenger aircraft in Portugal. Documents from the British Air Accidents Investigation Branch said a rotor blade had snapped, puncturing the engine's housing and causing minor damage to the wing. In September, 2000, part of a GE CF6 series engine was ejected and penetrated the left wing of a US Airways aircraft at Philadelphia International Airport.
Aer Lingus uses a variety of the aircraft engine, but has no plans to ground any aircraft. The CF6-80E1 is the most recent version and was designed specifically for the A330 Airbus.
This engine is in use on seven Aer Lingus A330 transatlantic aircraft.
The Aer Lingus head of corporate affairs, Mr Dan Loughrey, said the airline had no cause for concern about its own fleet and had received no recommendations to carry out extra checks.
