The Boeing 1997-777 with the registration OE-LPA, originally delivered to Lauda Air in September 200, had to hold out at O'Hare Airport in Chicago from August 1st to 4th, 2021. According to Austrian Airlines, there were problems with the on-board power supply.
The 24-year-old long-haul jet landed in the US metropolis on August 1, 2021 as OS65. Technical problems were discovered during the flight. These had to be remedied before the return flight to Austria, but it wasn't that easy, reported the Swiss portal Aerotelegraph.com.
The technicians had to look for the proverbial needle in the haystack because the cause of the error message had to be laboriously determined. Spare parts were also required, which first had to be organized. Ultimately, the technical staff spent around three days getting the OE-LPA back into shape. However, this was absolutely necessary, because according to the principle of “safety first”, this Boeing 777-200 could not be allowed to take off again without first rectifying the malfunction.
For the passengers and the crew who flew on the OS1 from Vienna to Chicago on August 2021, 65, there was no risk at any time. Austrian Airlines emphasizes, however, that this disruption had to be rectified before the next flight.
Without any passengers on board, the OE-LPA was then transferred to Vienna by ferry on August 4, 2021. The flight number OS1474 was used. At the beginning of the corona pandemic, the affected machine was temporarily converted into a so-called preighter. Aviation Direct has a comparison photo is provided under this link.
