@Geopiet To był PZL-130 Orlik (na podstawie innych pytań). Śmigłowiec ma wirnik i rzadko posiada chowane podwozie :-) Chodzi najprawdopodobniej o ten wypadek http://lotniczapolska.pl/Orlik-ladowal-bez-podwozia,23288

powody unieruchomień (1) When there is a propeller sudden stoppage because of an event such as a catastrophic engine failure or seizure, remove the propeller and any engine driven/powered accessory.

(2) If the sudden stoppage is because of a foreign object strike, follow the steps in the Foreign Object Strike section of this chapter.

On numerous occasions Textron Lycoming has been consulted about recommendations on whether to
continue using an aircraft engine that has been involved in the separation of the propeller/rotor blade from
the hub, the loss of a propeller/rotor blade tip or sudden stoppage following accidental propeller/rotor
damage (such as propeller/rotor strike). - http://www.lycoming.textron.com/support/publications/service...

samolot czy helicopter? The helicopter Starflex rotor head and drive train flexible couplings exhibited the torsional damage signatures typically associated with sudden rotor stoppage under considerable driving power. - http://www.ntsb.gov/investigations/fulltext/AAB0402.html

------------

Information received from the operator and from the maintenance organisation indicated that there had been no known tail rotor strike or sudden rotor stoppage since the helicopter was placed on the Australian aircraft register in 1992. - http://www.ntsb.gov/investigations/fulltext/AAB0402.html

------------

The TSB Engineering Laboratory examination of the tail rotor drive shaft determined that the direction of the torsional overload failure indicated a sudden stoppage of the tail rotor blades, - http://www.tsb.gc.ca/eng/rapports-reports/aviation/1998/a98w...
