Embraer EMB-120 Landed Safely After Pitch Excursion
The crew of an Embarer EMB-120 on a cargo flight had a pretty
wild ride on February 16th. On approach to Iliamna, AK, the
airplane suddenly pitched down 20 degrees .... twice. Fortunately
the pilot was able to recover and land the airplane safely, but
what they found on a post-flight inspection will likely surprise

On February 16, 2012, at about 1308 local time, an Embraer
EMB-120, registration N1110J, operated as cargo flight 1291 by
Everts Air Cargo, experienced an uncommanded pitch down while
descending into Iliamna Airport, Alaska.
The captain reported that the flight from Anchorage had been
otherwise uneventful until, during the descent at about 250 knots
airspeed with his hands on the controls and the autopilot engaged,
the airplane pitched to about 20 degrees nose down. The captain
reported he then disconnected the autopilot and adjusted the pitch
trim in the airplane nose down direction while pulling back on the
column to recover from the pitch excursion.
The flight crew declared an emergency, and at about 200 knots
airspeed, the airplane pitched down a second time while the captain
was hand flying as he continued the descent into Iliamna airport.
The captain elected to make a high speed, flaps up landing and
landed on runway 35.
Post-flight inspection revealed that the left elevator was bent
at the mid span trim tab, had partially detached from the aircraft,
and was missing two attachment bolts.
