AIRCRAFT ACCIDENT REPORT: IBERIA LINEAS AEREAS DE ESPANA (IBERIAN AIRLINES). MCDONNELL DOUGLAS DC-10-30, EC CBN LOGAN INTERNATIONAL AIRPORT, BOSTON, MASSACHUSETTS, DECEMBER 17, 1973

About 1543 e.s.t. on December 17, 1973, Iberia Lineas Aereas de Espana Flight 933, a DC-10-30, crashed while making an instrument landing system approach to runway 33 L at Logan International Airport, Boston, Massachusetts. Thirteen passengers were injured slightly; two passengers and one flight attendant were injured seriously during evacuation. The aircraft was substantially damaged. The National Transportation Safety Board determines that the probable cause of this accident was that the captain did not recognize, and may have been unable to recognize, an increased rate of descent in time to arrest it before the aircraft struck the approach light piers. The captain's ability to detect and arrest the increased rate of descent was adversely affected by a lack of information as to the existence of the wind shear and the marginal visual cues available.
