Spoiler Issue May Be Factor in Fatal
GIV-SP Crash
A
preliminary report
indicates asymmetrical spoiler deployment may be a factor in the December 15
crash of a Gulfstream IV-SP in the Dominican Republic that killed all nine on
board. Registered as HI-1050 to Helidosa Aviation Group, the twinjet was
operating as a charter flight to Orlando, Florida.
According
to the report, HI-1050 arrived at Higuero/La Isabela-Dr. Joaquín Balaguer
Airport earlier that day, following a flight from San Juan, Puerto Rico. En
route, there was communication between the crew and the company about replacing
the right-wing spoiler actuators. After arrival, the aircraft was towed to the
Helidosa hangar, where the company worked for three hours to replace the
right-wing ground spoiler actuators.
After
the crew and passengers boarded, CCTV footage shows the pilots doing a control
check. The spoilers on both wings extended, but only those on the left wing
retracted again. The aircraft was seen taxiing for departure with the three
spoilers on the right wing still extended. An image of the airplane in flight
captured by a witness on the ground showed that the right-wing spoilers were
still extended, but the ones on the left wing were not.
After
takeoff flight control problems developed immediately, and the flight crew declared
an emergency. They decided to divert to Las Américas International Airport and
hit trees and terrain about 650 feet to the right of Runway 35.
