View Full Version : control locks were still locked when the aircraft took off ( Video-Footage )

An excellent reminder that there really are good reasons to do a
thorough preflight and to make sure the controls are free. This
happened just north of Winnipeg, and the aircraft was the first version
with PT-6-67 Turboprops. The Canadian DOT concluded that the control
locks were still locked when the aircraft took off.

Even without preflighting how do you miss the fact that the controls don't
move?

You don't move them until liftoff.

At least in the planes I fly, checking for proper control motion is a
checklist item during the run-up. Removing the control lock is one of the
first preflight items. So there are at least two opportunities to catch
this.
If there's a nontrivial wind, then correction for wind during taxi
provides a third opportunity.

During the preflight walk-around, I also manually move the ailerons and
elevators (ruddervators in the V35) to both get a good view of the
connecting bolts and to confirm movement, which is ultimately confirming
the removal of the gust lock.

And what airplane has a gust lock that allows the plane to take off?

The prompting cautionary tale I was told relating to that part of a small
plane walkaround was the demise of Aristotle Onassis Jr. I never heard the
name of the guy who grabbed the control column when his faulty seat slid
back on takeoff. Fame is a significant memory-jog. As is death.

The aircraft in the video that prompted this thread?

It is funny that they through into the report that he had a heart attack
right before the crash, probably not to mention an extreme and violent bowel
movement!

Good point; that's yet another.
[On the 172s/182s I fly, I also confirm that moving the elevator moves
the trim tab.]

Then there were the "winners" that stole a 172 in the middle of the
night and drove off the end of the runway at 100 knts..
The elevator (s) had been removed for repair...

As well as Rod Machado's oft-told tale of the enthusiastic student who
pronounced the C150 ready after a thorough preflight only to be brought down
several pegs when it was pointed out that the plane was lacking a prop.

An understandable mistake as on a hot day it would accelerate about the
same.

Isn't that what Boeing claims to have happened on the very first B-17
prototype test flight?
