Here is a time lapse video of a B767 APB replacement; an example of an identical operation that we are currently doing in one of our hangars for a customer. (Same, except we are doing the version where you leave the horizontal stabilizer in place)

Wish I could take pictures of what we have going here locally. It looks pretty awesome. But this should give you an idea of what it all looks like.

Right now, in one of our hangars: A Boeing 767 is in the middle of having its Aft Pressure Bulkhead (APB) replaced. All due to tailstrike damage.

The short version of the process, is this:

- Remove Vertical stabilizer, and set it aside
- Remove all the fasteners going around the APB mount flange
- Crane the aft unpressurized part of the aft fuselage & horizontal stabs to the
ground
- Remove the APB from the aft fuselage assy you just removed
- Install new APB
- Reinstall everything in reverse order

Sounds easy, no?

Picture is not mine, it is Boeing's, from a different job somewhere. Same operation though. (We aren't allowed to take any pictures of what we are doing here on this particular job)

There's a thread of conspiracy
Sewn right into my headgear
Over under and whipstitched
In contrasting color
Constantly constricting my thinking
Slowly drawing itself tight
Until the blood flow is just about right
For alternative thinking to take place

It isn't very false
And it isn't very true
It's totally alternative
And tells me what to do

Nine sources tell me one thing
While one tells me another
Logic says one thing
But my gut screams "However...."
That one thing seems to comfort my thoughts
Coddling my mind
In cheap velour
From the bargain bin at K-mart
A blue light special of an idea
So I'll latch right onto that

It isn't very false
And it isn't very true
It's totally alternative
And tells me what to do

My head is now an alternative shape
Thanks to that too tight hat of mine
Made of shiny upcycled tinfoil
And whispering secrets to me all the time
I'll not question its authority
I'm way past that now
Two miles past the military checkpoints
Heading into Area Fifty-One
Helped by the invisibility afforded me
By that low tech high magick
Too tight sparkling custom made
Tightly stitched protective tinfoil hat

It's not very false
And it isn't very true
It's totes an alternative
Telling me what to do

First flight of the Douglas DC-7.
 
The Douglas DC-7 is a transport aircraft built by the Douglas Aircraft Company from 1953 to 1958. It was the last major piston engine-powered transport made by Douglas, being developed shortly after the earliest jet airliner - the de Havilland Comet - entered service and only a few years before the jet-powered Douglas DC-8 first flew.

There is a 1,000 person-dot daily life flow animation, that is absolutely hypnotizing to watch, at this site. I kept trying to see myself as one of the dots, and failing. But it was still fun.

Stuffed about $30k worth of inspection equipment into the old Geo Metro, and worked through the night last Thursday, out on the ramp.

Equipment blues were getting me down. :(

Usually our equipment works great. Everything just seemed to break on me at once that night.

I've been busy borescoping lately. Here I'm set up and recording the LE of the 3rd Stage LPT, in a Pratt JT9D-7R4D engine.

I use a lot of copper tubes, bent in certain ways, to help me do the borescopes. One important thing I've learned, is the need to set up things so you can watch the blades "hands free". Just because over the course of multiple 3 - 4 minute stretches of holding the 6 mm scope in just the right place, without letting it move at all; makes for cramped hands, which is distracting to the process of watching for, and evaluating any damage to the blades.

There are kits of custom steel tubes you can buy, for each engine type. But I wouldn't know anything about that.

This Day in Aviation History
May 9th, 1949
First flight of the Republic XF-91 Thunderceptor.
 
The Republic XF-91 Thunderceptor (originally designated XP-91) was a mixed-propulsion prototype interceptor aircraft, developed by Republic Aviation. The aircraft would use a jet engine for most flight, and a cluster of four small rocket engines for added thrust during climb and interception. The design was largely obsolete by the time it was completed due to the rapidly increasing performance of contemporary jet engines, and only two prototypes were built. One of these was the first US fighter to exceed Mach 1 in level flight.
 
A unique feature of the Thunderceptor, which makes it instantly recognizable, is the odd wing planform which has much greater chord at the tips than the root, the opposite of typical swept wing designs. This was an attempt to address the problem of pitch-up, a potentially deadly problem that plagued early high-speed designs. The Thunderceptor's design meant the entire wing stalled smoothly, more like a straight-wing design....
