At 0431 A.s.t., July 11, 1975, a propeller blade separated from the No. 2 propeller of Puerto Rico International Airlines, Inc., Flight 303, during takeoff at Puerto Rico International Airport, San Juan, Puerto Rico. The takeoff was discontinued and the airplane was stopped on the runway pavement. Of the 11 occupants, 1 was injured slightly. The airplane's flight controls, electrical system, and No. 2 engine were damaged heavily. The National Transportation Safety Board determines that the probable cause of the accident was the separation of the No. 1 propeller blade of the No. 2 propeller assembly. The blade separated as a result of vibratory stresses which induced fatigue cracks not readily detectable during routine preflight inspections. Contributing to the accident were inadequate overhaul inspection procedures at a certificated repair station and inadequate dissemination and enforcement of recommended maintenance practices by the Federal Aviation Administration.
