| Subject: | Re: Acceleration and wild rides |
Ok, pissing contest getting started.
1). 3 air-to-air combat training flights to test P&W engines with new software.
2). Terracing following shakedown flight in Lake Isabella MOA. 400 knots and 100
foot AGL.
3). GPS qualification with new engine software. 10 bombing runs using GPS tracking
bombs.
4). During shakedown flight, was given the stick and taught how to do 4 and 8 point
rolls.
5). Air-to-air refueling with the Flight Test Center Commander, General Engel.
Testing a modification to correct engine response.
As a propulsion engineer, we got to ride in the backseat of our test aircraft.
Flights occurred over a period of just over year.

I assume it is a much more benign catapult than an F/A-18, but let me tell
you, it is an e-ticket ride. Sitting backwards in the cargo space during
the cat adds an interesting twist. Trapping is pretty boring IMHO.

their harness. Well, the C-2 pilot decided to fly back to San Diego (about
80 nm) at about 200 MSL. He pushed over and I watched the crewmember go airborne
then come crashing down. Funny. Good thing he was wearing headgear.

OK, what is the trick to getting the bushings installed? -I tried fabrica

other 3 didn't.=0A=0AIs there a better solution for these bushings?

| Subject: | Oil consumption has increased...maybe |
I've been losing more oil than usual so am now both tracking consumption mo
re closely and looking for ways to decrease it.
Research had dissuaded me from considering air-oil separators. I'm going t
o do the trick of rerouting the breather hose in a higher arc under Gary's
cowl. I'm wondering if there's a venturi effect going on too. The 'whistl
e' slot is way up inside. My question is how far should the tube extend fr
om the Jaguar cowl? Same 1inch +/- 1/2inch? Gary is probably the only one
who knows the pressures and flows enough to say.
So what happened? Maybe just normal engine wear on a mid-time engine=2C or
maybe I'm running it harder because I can with the new cowl. By the way
=2C I'm consistently seeing roughly 5-10 KTAS better than book with about .
5 gph less than book for the given rpm (tach is accurate) leaned aggressive
ly by ear (from just rough back to smooth) and backed up by a JPI EDM-700.
So that's a reliable 135KTAS at around 9.0gph in the mid altitudes (2500rp
m). Besides the steps off=2C K&N air filter=2C and powerflow (as required
by the STC) my airplane is mostly stock and a bit bent.

I use large rivet dimple dies (-5) to expand the non-flanged end of the.bushings.
Worked good for a decade or more.

It's been about 6 years ago but as I recall Garner has a tool that he loans o
ut when you get the bushings and seal material from him. The tool must have w
orked pretty good because I don't remember it being a difficult repair
