Lufthansa -according to "Der Spiegel"- opened an internal investigation to verify if a maintenance error could have caused the landing gear of the Bombardier Global 5000 aircraft of the German Air Force (Luftwaffe) used to transport the exponents of the Government. A decision taken since the aircraft had been subjected to maintenance work by Lufthansa Bombardier Aviation Services technicians a few weeks ago, controlled 51% by Lufthansa Technik that is interested in identifying a potential "problem" not revealed during the checks on the Global 5000.

The investigations, however, are not only carrying out Lufthansa, but also Luftwaffe and the Luftfahrt-Bundesamt (the national civil aviation authority) have opened two inquiries into the inconvenience that caused delays at Berlin-Schönefeld airport and serious damage to the plane, which for a long time will remain inoperative causing further difficulties for the transportation of members of the federal government.
