The Piper turbo arrow that I fly from time
to time has a small turbo charged continental six cylinder engine with a low
and high boost pump switch. If you accidentally put the high boost on, it
kills the engine.
The high and low boost switch is a three
way switch with a metal locking mechanism that won’t allow you to turn on
the high boost with out pushing the metal guard up. It takes some effort to
do…

I was advised when I built my panel not
to put the high boost and low boost on a three way switch. The reasoning
was you could easily go to turn off the low boost and accidentally hit the
switch all the way to high boost. Is that what the NTSB is suggesting
here?
