PROBABLE CAUSE:
"The KLM aircraft had taken off without take-off clearance, in the absolute conviction that this clearance had been obtained, which was the result of a misunderstanding between the tower and the KLM aircraft. This misunderstanding had arisen from the mutual use of usual terminology which, however, gave rise to misinterpretation. In combination with a number of other coinciding circumstances, the premature take-off of the KLM aircraft resulted in a collision with the Pan Am aircraft, because the latter was still on the runway since it had missed the correct intersection." KLM Flight 4805 was a charter flight for Holland International Travel Group and had arrived from Amsterdam Airport Schiphol, Netherlands. Its captain was Jacob Veldhuyzen van Zanten, age 50. At the time of the accident, Veldhuyzen van Zanten was KLM's chief flight instructor, with 11,700 flight hours, of which 1,545 hours were on the 747. The first officer was Klaas Meurs, age 42. At the time of the accident, Meurs had 9,200 flight hours, of which 95 hours were on the 747. Flight engineer was Willem Schreuder, age 48. At the time of the accident, Schreuder had 15,210 flight hours, of which 540 hours were on the 747. The aircraft was a Boeing 747-206B, registration PH-BUF, named Rijn (Rhine). The KLM jet was carrying 14 crew members and 234 passengers, including 52 children. Most of the KLM passengers were Dutch, while also on board were 4 Germans, 2 Austrians and 2 Americans. After the aircraft landed at Tenerife, the passengers were transported to the airport terminal. One of the inbound passengers, who lived on the island with her partner, chose not to re-board the 747, leaving 234 passengers on board.
Pan Am Flight 1736 had originated at Los Angeles International Airport, with an intermediate stop at New York's John F. Kennedy International Airport (JFK). The aircraft was a Boeing 747-121, registration N736PA, named Clipper Victor. Of the 380 passengers (mostly of retirement age, but including two children), 14 had boarded in New York, where the crew was also changed. The new crew consisted of captain Victor Grubbs, age 56, first officer Robert Bragg, age 39, flight engineer George Warns, age 46, and 13 flight attendants.
At the time of the accident, captain Grubbs had 21,043 hours of flight time, of which 564 hours were on the 747. First officer Bragg had 10,800 flight hours, of which 2,796 hours were on the 747. Flight engineer Warns had 15,210 flight hours, of which 559 hours were on the 747.
