The American aviation authority is investigating whether aircraft manufacturer Boeing falsified documents. This is said to be about inspections of the 787 Dreamliner that may not have taken place or been completed.

The Federal Aviation Administration (FAA) announced on Monday that it had opened an investigation into Boeing. There are two subjects of the investigation: Firstly, there is a suspicion that Boeing may have noted inspections of the 787 Dreamliner that “may not have been completed yet”.

Second, the FAA is investigating “whether Boeing completed inspections and whether company employees may have falsified aircraft records.” That means Boeing may have falsified inspection certificates.

The FAA said Boeing “voluntarily informed us in April” that the plane maker may not have performed the necessary inspections to confirm where the wings on certain 787 jets connect to the carbon fiber fuselage , there is sufficient connection and grounding.

The agency also said that Boeing “must reinspect all 787 aircraft still in production and also develop a remediation plan for the in-service fleet.”

The aviation company Boeing has been extremely criticized for months. After a door plug on a 737 Max 9 flew off during the flight in January, leaving a hole in the fuselage. Only with luck there were no deaths or injuries. After that incident, the FAA accused Boeing of “multiple instances” of quality control deficiencies in 737 Max production.

In addition, the crashes of two 737 Max aircraft, in which a total of 346 people died in 2018 and 2019, have not yet been finally clarified. Faulty flight software was blamed for both crashes.

The company is also under political pressure. Last week, the US Senate addressed the security problems in a hearing. Boeing engineer Sam Salehpour, who had contacted the FAA as an informant with warnings about the safety of the Dreamliner models, also testified.
