NTSB Releases Report Of Phenom 300 Crash

Tue Jun 07, 2016 9:19 pm

The NTSB has relased their report into Phenom 300 crash in Gaithersburg, Maryland in December 2014. Due the fact the pilot failed to turn the deice/anti ice system in the airplane before landing, the plane developed ice and stalled at 92 Knots

NTSB Releases Report Of Phenom 300 Crash

Interesting that he wrecked a plane at the same airport 4 years prior because of another stall event.

I'm confused by this comment:

“If he had turned on that de-icer, his airspeed would have been 126 [knots], not the 92 that it was,” when it stalled and crashed, Tim LeBaron, head of the NTSB’s investigative team, told the board Tuesday.

Ice on the wing raises the stall speed. Is he saying it stalled at 126 knots instead of the 92 it normally would stall at? Or is he saying he was actually going 92 knots instead of 126 knots because of the ice? If the latter, why? Increased drag? Increased angle of attack to maintain the glide slope?

Nevermind, I read the full report and see the explanation. The pilot programmed the landing speed in at 92 knots assuming an ice free landing, when it should have been programmed at 126 knots for a landing with de-icing activated, which assumes icing present.

I guess this means the plane was still on full autopilot during the crash? I wonder if he had been handflying the jet, would he have had more feedback on the pending stall and been in a better position to do something about it.
