The paper deals with key issues related to the operation of the driving unit of the PZL-130TC1 'Orlik' aircraft. The author has focused in particular on deficiencies of the aircrew drive LUN-7816, whose intensity affected both operational safety of the PZL-130TC1 'Orlik' aircraft and continuity of training programs for pilots. The paper puts forward some hypotheses on why airscrew drives have been damaged and presents the methodology of the studies. The structure of the object under investigation is described along with the chain of measurement, with consideration to the fact that frequencies characteristic for detrimental dynamic phenomena are virtually unknown and there are substantial constraints to measurements that can be taken in-flight. Initial results are outlined of investigations of the driving unit tests completed both on the ground and in-flight. All the addressed topics are illustrated by examples.
