Of fake spare parts were provided to the maintenance of CFM-56 engines which also equip single-aisle aircraft Airbus A320 than single-aisle aircraft Boeing 737 NG.

The engine manufacturer CFM Internationala joint venture of the American General Electric and the French Safran, confirmed this information reported last week by the financial agency Blomberg. “We fully support regulators’ investigation into falsified certification documents accompanying parts sold by AOG Technics“, a CFM International spokesperson said in a statement yesterday.

The engines concerned are of the CFM-56 type and equip the Airbus A320 and the Boeing 737 NG, two generations of single-aisle medium-haul aircraft now replaced, respectively, by the A320neo and 737 MAX. These notably use new generation “Leap” reactors from CFM, which are not affected by the alert. No details were given on the number of engines potentially affected. 34,000 CFM-56 engines were produced.

For its part, the European Aviation Safety Agency (EASA) has required airlines and maintenance companies to “inspect their records to determine whether any appliance or engine parts were obtained from AOG Technics, directly or indirectly ”, and verify the authenticity of their certificates. In the event of proven falsification, “any affected part should be kept out of the way to prevent its installation », added EASA. If the parts are already installed, the agency recommends replacing them with approved parts. The British company AOG Technics has so far not provided any explanation or confirmation of this information.
