Executive Summary:Loftleidir Icelandic Airlines, Inc., Flight 509, a scheduled passenger and cargo flight , was involved in a landing accident after an instrument landing system (ILS) approach to runway 31R a t the John F. Kennedy International Airport, i n Jamaica, New York. The accident occurred at 0358 e.d. t., on June 23, 1973; 119 passengers and 9 crewmembers were aboard the aircraft. Six passengers and two stewardesses were injured seriously; there were no fatalities.

Just before touchdown and when the aircraft was on the flare , the captain called for the ground spoilers to be armed. During the arming process, the activating lever was inadvertently pulled back, which caused the spoilers to deploy fully. The aircraft's rate of descent promptly increased, and the aircraft struck the runway, tail first, 20 feet short of the displaced runway threshold. The aircraft was damaged substantially.

The passengers and flightcrew used inflatable escape slides to evacuate the aircraft. The evacuation was orderly, and no injuries resulted.

The National Transportation Safety Board determines that the probable cause of the accident was the first officer's inadvertent deployment of the ground spoilers in flight while he was attempting to arm the spoiler system. The captain's decision to delay arming of the spoilers until just before touchdown was a contributing factor, because the tim - ing varied from normal procedures and required the crewmembers to act quickly, without time for corrective action.

As a result of this accident and of a review of similar accidents, the National Transportation Safety Board on December 7, 1973, made two recommendations to the Federal Aviation Administration. (See Appendix E.)
