That's it, compressor stall, I shoud've remembered. That explains
(probably) the pulsing thrust & fire, not having a smooth, even
airflow to the burner section (cans). I wonder how much, if any,
thrust was being produced.

Probably quite a lot. Doesn't look like they had a lot of rudder in. and
the airplane isn't yawing back and forth with the pulses, so they
probably weren't that fierce.


Yeah, it's often walnut shells used for the compressor & turbine
washes.

We didn't get to work on any large turbine or turbofan engines in
powerplant training. We overhauled some ancient PT-6s and did a hot
section on a small Allison.

Today (start of new semester & start of airframe training) we began
learning how to drill out rivets. Choosing the right bit for rivet
size, learning the air drill, keeping the bit straight & smooth to not
screw up the hole, the tough part for me was popping the head off! I
kinda got it after about 20 rivets but it's gonna take practice.

Cool. I only make smileys when I try and rivet!

I also passed my long-overdue medical Monday, paving the way to get
back in the cockpit soon as I can afford it. Dang, I forgot my wallet
got stolen last year including my certificate. Gotta get with FAA to
get a replacement.


Yes, you'll need that.
