On Apr 20th 2015 Germany's BFU released their final report concluding the probable causes of the serious incident were:

Immediate Causes:

- Due to an omission during the installation of the cabin pressure controller the shipping plug was not removed from the static port as required by written procedure.

- During the flight a pressure difference was measured and the OFV opened which resulted in rapid decompression.

Systemic Causes

- The shipping plug was not clearly noticeable and did not carry a tag.

- The pressurisation system ground test after installation was not suitable to detect the error.
