Eighty three accidents between 1975 and 1977 involving propeller failure included 48 cases of blade of separation. It is noted that almost all of them could have been prevented if more attention were given by pilots to the propeller's condition during preflight examinations. The dynamic and vibratory stresses acting on the propeller, and the causes of blade fatigue and failure are explained. Examination for airworthiness, annual inspections, repairing and replacement are discussed. The maintenance of records of where and when maintenance was done is important. Hints for avoiding accidents are noted.
