Plane Loses Both Wings In Mid-Air............Why ?

[Lufthansi]

This happened on some Airshow in Asia. The Airplane last both wings in
midair and consequently crashed. Maybe it did some aerobatic loops
prior to wing-failure ? Check it out :

Everybody wants to be Bob Hoover.

I don't think it is this video, but a different one several years ago
when a pilot doing loops in a Partenavia during an airshow folded the
wings back. It was his wife who was shooting the video if I recall.

Someplace in Texas. Midland, maybe?

My understanding is that this guy had been doing this for awhile. He
routinely over stressed the airframe until the eventually gave back.

The video was that of a Partenavia coming apart. They are NOT aerobatic
category airplanes. It looked as if the pilot had started a snap
maneuver, in which both outer wing panels failed simultaneously.

First, I don't want to offer any encourage any one to try aerobatics
except in a plane rated for them.

The way I see it, virtually any *basic* aerobatic maneuver can be done
without causing undue stress in a good portion of normal and utility
category aircraft. The twin is a different animal due to inertia and
the weight out there on the wings., but Bob did an outstanding job. If
anything he may have made it look too easy<:-))


The snap roll is normally considered a bit hard on airplanes, but I've
seen a number of rag and tube aircraft do snap rolls nose high and at
a low speed. The "Flying Farmer" used to do a routine with a number
of snap rolls, but they sure weren't the ones most people think of
when they see air show performers doing snap rolls at higher speed.
"Those things are uncomfortable"

Almost any single engine plane could do a hammer head, but be a bit
late and you may have to walk home if it leads to a tail slide. <:-))

Barrel rolls are probably one of the easiest maneuvers to learn and
the easiest to screw up.

However after reading the subject line and original post I keep
wondering how you have a mid-air accident by your self? Is it half
way between the top and bottom, or the edges. I can see how top and
bottom are defined although I've never flown anything capable or
coming near the top and the bottom adds new meaning to "hard deck".
I've just never been able to figure out where the sides are located.

The crash of this P-68 was way back in the '80s here in the U.S. The
guy was doing aerobatic demos to show the airplane off for, IIRC, the
Partenavia factory.

The NTSB report says he pulled just over 8G and pulled the wings off.
If you had the original audio you could hear his wife narrating his
flight....sad.

Both wings seemed to fail at essentially the same instant, and in the
same place (just outboard of the engines).

Eek; that model or something very like it is one of only two small
planes I've been in, and the only one I've gotten to manipulate the
controls of. But the pilot who took me up wasn't trying to do
aerobatics with it!

At least not pulling too many g's. :-) Bob pulls just enough, but not
too much.

I'm wondering if the sudden change in G forces abruptly after the wings
snapped may have knocked out the pilots so that they didn't have to see
the ground coming uo to smight them...

You can bet that this was not the first time he had done aero in an
unapproved aero plane, and though I hate to say it, he got what he
deserved.

Kick superman in the shins, and sooner or later, he is gonna crush your
butt.

I wish we could distribute this video to all new pilots, and a few of the
old ones, like NW Pilot, too.

Plainview, 9/11/83:

THE PLT WAS EXECUTING A HIGH SPEED PASS OVER THE RWY AT ABOUT 250 FT
AGL. THE PLT THEN BEGAN A RAPID PULL-UP & BOTH WINGS SEPARATED JUST
OUTBOARD OF THE ENG NACELLES. RECONSTRUCTION OF THE SEQUENCE FROM A
VIDEOTAPE REVEALED THAT THE ACFT'S SPEED AT THE TIME OF THE WING
SEPARATIONS WAS 220 KTS. VNE FOR THE ACFT IS 193 KTS. IT WAS CALCULATED
THAT, AT 220 KTS & AN 8 DEG NOSE-UP PITCH, THE 'G' LOAD AT THE
TIME OF THE WING SEPARATIONS WOULD HAVE BEEN 8.3 G'S.

Honestly, what makes anyone think doing that is a good idea?

In Asia?
This accident took place in Plainview Texas.

NTSB Report:
http://www.ntsb.gov/ntsb/brief.asp?ev_id=20001214X44523&key=1

[Michael R]

He had been doing it for a while.

What was different this time was that a reporter did a TV story on him. He
took the reporter up they taped some aerobatic maneuvers and an interview in
flight, before the airshow. It was thought that the pilot may have pulled up
harder this time because he knew it would be on TV.
