Plane crash in Trudering - Flugzeugabsturz in Trudering
The pilot of the Piper PA-31T Cheyenne II , a professional pilot and very experienced on the Cheyenne, was on a check flight to extend his ATPL with an examiner and a secretary from the Air Office in Southern Bavaria . The machine with the registration D-ILRA was the company aircraft of a Bavarian metal construction company. During the approach shortly before runway 07R in Riem , the examiner intervened surprisingly and - as the aircraft accident investigation department at the LBA later determined - "without notice in a completely unsuitable situation" at around 60 meters above ground, the power lever of the right engine back to idle. 
The pilot should probably show that he can land the machine even if an engine fails. A standard procedure, but because of the torque of the left engine - and the surprising lack of compensating torque of the right turbine - the machine turned around its longitudinal axis to the right and down and picked up speed. Thanks to the drive, the pilot was able to intercept the machine just above the road, but only one meter above the ground. With propellers scratching the ground, she slid across an intersection on Wasserburger Landstrasse , beheaded a cyclist with her wing nose and brushed against a bus on route 192. Its driver lost control and drove into a McDonald’s-Restaurant. The machine also hit the building. A wing tore, the kerosene ignited and set the building, aircraft and parts of the bus on fire.
The three occupants of the plane died instantly. Three other people died on the ground. In the following weeks three of the 30 injured died. The restaurant was destroyed and rebuilt in the same place.
Criticism and consequences
The accident led to a reform of the examination system at the two Bavarian air offices. The flight was a check flight that has to be carried out every six months to extend the ATPL professional pilot's license and type rating. So far, employees and officials of the air authorities in Bavaria have carried out these demanding tests. Although they had the necessary type ratings , they did not have the practical experience of their test subjects and certainly not their in-depth knowledge of the respective aircraft types. Criticism from pilot circles of this Bavarian procedure had gone unheard to date. 
After the accident, the Bavarian air authorities also accepted the procedures used in all other federal states. There, air authorities transfer the check flights to experts as assessors: chief pilots, fleet managers, check captains at airlines, training managers or flight instructors with instruction authorization carry out these tests from Schleswig-Holstein to Baden-Württemberg - experts who are extremely familiar with the samples of the respective test subjects because they fly it professionally. Since the Trudering accident, such checks have also been carried out in Bavaria - in the simulator or in the aircraft - by active professional pilots and not by officials. 
On the opposite side of the street (Truderinger Strasse corner Nikolaus-Prugger-Weg) the City of Munich placed a memorial stone in a small green strip.
