Birds Hit Boeing 767 Jet, Leave Hole In Main Wing

Wed May 17, 2006 3:03 am

Quote:
Hokkaido International Airlines, the Sapporo-based carrier known as Air Do, said Tuesday that birds hit one of its Boeing 767 aircraft in midair Monday night, leaving a hole in one of the plane's main wings.

According to the airline, the two-engine jet, which had left Tokyo's Haneda airport, was about to land at Sapporo's New Chitose Airport around 8:45 p.m. when birds collided with its right wing, creating a hole about 30 centimeters wide.

No one was injured in the incident, but it caused Air Do to cancel a total of 15 flights between the two cities, the carrier said.

WTF ? 30 centimeters ?

Could you see through the hole, or was it just in one wing panel ? Any info on the bird species ? Could we assume that the hole is in the outer wing ?

That's actually eerily similar in size to the big hole the foam caused in Columbia's leading edge ... speed of impact was probably similar as well.

Anyone know the species of bird? That had to be some amazing impact ...

It has to be translation error. They must have meant 30 cm dent, not a hole.

If the speed of impact was the same then Columbia would have never made it out of the atmosphere. Earth's escape velocity = 11.2 km/s, or 1.12 x 10 4 m/s. The speed of a 767 flying at an altitude low enough to hit a bird is probably around 250KIAS, which works out to 0.138 km/s, or 1.38 x 10 2 m/s. Bit of a difference I think.  Wink

Some where on the net is a series of pictures of an American 767 that hit some birds while departing out of LHR I think. One bird went clean through the radome, the pressure bulkhead, through the glareshield and ended up in the Captains lap.

Columbia never reached Earth's escape velocity. If it had done that, then it would never have crashed, but entered an eternal orbit around the sun.

It reached Earth low orbit velocity which is some 7.9 km/s.

But the speed when the foam hit the wing was much, much lower. It happened within the atmosphere. Columbia left the atmosphere (for all practical things) going around Mach 3 which is only 0.9 km/s at high altitude.

I don't know at what speed it happened, but it could easily have been at subsonic or low supersonic speed.

But then Columbia was a lot more fragile. Flying it on top of the B747 carrier at just 250 knots though a rain shower would totally destroy the thermal protection.

Birds leave holes if they and the aircraft are going fast enough, or the bird hits in a weaker area. I've seen pictures of a Piper Seminole that had a run-in with a large bird (i think it was a turkey vulture) while in flight. The bird entered the top of the wing, and went clear through, leaving about an 24 inch diameter hole on the right wing.

Can I ask, why is it so tough to comprehend a hole produced by the bird? Laws of physics could easily tell you that this was to happen if the conditions are right.

Not only that, but the foam was moving at the seem speed until it detached.

The relative speed at impact was even lower. I don't recall exactly, but I think the relative impact speed was in the 500 to 600 mph range. I might be low, but that is still fast enough to have caused the damage.

In 1995, a very severe thunderstorm hit DFW, and a number of AA jets were grounded, due to baseball and even larger hail damaging planes on the ground. A common problem was hail going through composite surfaces on the wings and horizontal stabilizers.

On the other hand, the DC-10s and 727s on the ground only suffered dents, since they had more metal surfaces.

This comment relates to the above since it involves birds and planes...

I remember watching a documentary on the development of the B777, and it also featured the design and testing of the giant GE engine. There was a clip of the engine, mounted in test mode, at full power. In order to test the strength of the fanblades and ability of the engine to continue running in adverse situations, many items were chucked into the engine, including ice, small bushes, and even large (dead) birds. It was very entertaining to watch the engines easily consume multitudes of birds, while showcasing their impressive uninterupted function.

Does anyone have a weblink to this clip?

by the way, check out this amazing clip of a bird taking out a military aircraft....

If the wing leaked fuel, then it was the main wing box.

It's very likely, though, that the bird penetrated an auxiliary structure in the wing (which is usually composite) or a slat/flap.

While you are there check with boeing.com and look for how much "structural steel" there is in the average B767!

DING DING DING - We have two partial winners !!!!!


Firstly, I know very well how to use Google, thank you.

Secondly, I have a pretty good idea how much structural steel is in an airplane (most likely very little) but that isn't really the point.

Perhaps it was my choice of wording that threw so many off the mark? I was talking about the structural steel used in high-rise buildings.

I thought the  duck  would have given it away.

Making a hole in the skin of a wing is hardly the same as the structural part of the wing taking on a building skeleton. Sad really!!

Sorry for the tone of my last post. The other thread is wearing on me.

Still though the comparison does not deserve to be glossed over and forgotten. All here should keenly understand just how fragile these wings really are. They are designed to fly through air, not birds.

Except that the 767 doesn't go into space nor has to re-enter the earth's atmosphere at thousands of miles an hour.

Had a DC-10 slat that got punctured by a bird two weeks ago. Hole was 19" X 13". Swapped the slat out at is would take too long to repair. A few bird incidents:

B763F, bird strike punctured leading edge access panel. Panel made of fiberglass.

About 20 yrs. back, an Ecuatoriana 707 took a bird strike over the Andes. Flight continued to MIA on 3 engines. Totaled the nose cowl, damaged fan and side cowls. The worst part is the smell...

A bird will do all sorts of damage to the structure. I am not surprised anymore by the damage they cause.

Do we classify this as a "near miss", a "near hit", or "loss of separation with an avian projectile?"

(We'd better check those orange black boxes.)

BTW, I've seen several instances of birds (or at least what's left of them) ending up embedded in the leading edge of aircraft. Believe me, it is a mess, both the bird and the plane.

I remember as a teenager I was a member of the RAF cadets and on camp one year helped out at the RAF Hawk (sub-sonic jet trainer) maintenance facity in Devon. We helped to dismantle the nose of a Hawk that had suffered a bird-strike - there was a hole in the nose about 20 cms accross and a series of smaller holes in 3 or 4 of the internal structural pieces of the plane - and nothing remaining of the bird other than a sort of pate substance splattered all over the inside of the nose!

Who is online
