Dutch report blames Boeing for Turkish plane crash

Final report on last year's THY plane crash in Amsterdam puts most of blame on manufacturer for downplaying the malfunctioning of one of the radio altimeters of the airliner

Dutch report blames Boeing for Turkish plane crash


Turkey's national air carrier Turkish Airlines (THY) announced on Thursday that the Dutch Safety Board had released its final report on the THY aircraft that had crashed while landing at Amsterdam's Schiphol Airport last February.

Releasing a statement, THY said the report indicated that the aircraft's left radio altimeter system had passed on an erroneous altitude reading, while the right radio altimeter worked properly as the plane approached the runway.

THY said the automatic throttle control system of the plane, which controlled the speed of the aircraft, got the relevant height information from the left altimeter and considered the wrong data as an indicator of landing at the ground.

"As a result, the automatic throttle system cut down the gas and caused the speed to decrease to a level below stall speed and gave rise to loss of control at an altitude very close to ground level," THY said.

THY also said that its technical department had found out about the malfunctioning altimeter problem long before the accident and notified the manufacturer company of the aircraft about the issue.

"However, the manufacturer removed such issue from its agenda in a very short time although the reported problems had not been solved," the airline company said.

Noting it disagreed with several points listed in Dutch Safety Board's report, THY said it would examine the document in a detailed way and deliver another statement on the issue if deemed necessary.

The THY plane, with flight number 1951, en route from the Turkish city of Istanbul to the Dutch capital of Amsterdam, slammed into a muddy field while attempting to land at the Schiphol Airport on February 25, 2009.

A total of 9 people, including four crew members, were killed and many others were wounded in the accident. Five of the 9 victims were Turkish and four others were U.S. nationals.
