The NTSB report seems to say that the pilots rushed the takeoff and did not remember that the gust lock was ON thus disabling the elevators. They blame manufacturer for a throttle interlock system that was so ineffective that it allowed the pilots to advance the throttle to 22-26 degrees and thereby reach 187 mph. The wreckage reveals the gust lock lever in the OFF position. I am not a pilot and have never been near a Gulfstream. Here are my questions.
- How unlikely would it have been for two professional pilots to forget to disengage the gust lock lever.
- Could the plane have reached that “V1” and “rotation” speed with the throttle limited to 26 degrees.
- Could the elevators still have been locked with the gust control lock OFF.
- Would a pilot routinely test the elevators before reaching V1.
- How impossible would it have been for someone not on the flight to have tampered with the system.
