Ethiopian B737 opens cockpit window in flight, twice, to clear debris from windshield

Sun Jan 19, 2020 12:10 am

Extenuating circumstances cause for extreme measures. Is this written in a operations manual somewhere?

Incident: Ethiopian B737 at Dire Dawa on Jan 9th 2020, swarm of grasshoppers

By Simon Hradecky, created Sunday, Jan 12th 2020 21:26Z, last updated Wednesday, Jan 15th 2020 19:45Z
An Ethiopian Airlines Boeing 737-700, registration ET-ALN performing flight ET-363 from Djibouti (Djibouti) to Dire Dawa (Ethiopia), was on final approach to Dire Dawa's runway 15 when the aircraft flew through a swarm of grasshoppers and received a huge number of insect impacts into engines, windshield and nose of the aircraft. The crew went around, attempted a second approach but again needed to go around and diverted to their ultimate destination Addis Ababa (Ethiopia), where the aircraft landed safely about 90 minutes after departure from Djibouti.

The aircraft remained on the ground for about 11.5 hours for cleaning and a thorough inspection, which found no damage.

The United Nation's Food and Agriculture Organisation (FAO) reported on Jan 6th 2020: "The Desert Locust situation remains extremely serious in the Horn of Africa where it threatens pastures and crops in Ethiopia, Somalia and Kenya. Numerous swarms have formed in eastern Ethiopia and adjacent areas of northern Somalia. A number of large immature swarms moved south in the Ogaden of eastern Ethiopia and adjacent areas of central Somalia and reached southern Somalia, southeast Ethiopia and, on 28 December, northeast Kenya." The FAO warns a dangerous situation arises at the Horn of Africa and on both sides of the Red Sea.

On Jan 15th 2020 The Aviation Herald received information based on a screenshot reportedly showing the report of the captain of the flight, that the aircraft was on approach to Dire Dawa's runway 15 when the aircraft entered a swarm of locust, it was like rain. The windscreen wipers were not able to clear the windshield anymore. The crew went around, climbed to 8500 feet, depressurized the aircraft, opened the cockpit side window and cleaned the windscreen by hand. The same happened on second approach to Dire Dawa. The crew again climbed to 8500 feet, cleaned the windscreen by hand again and diverted to Addis Ababa.

How did it not tear his hand off? Weren’t they going at least 200-250mph?

Glad the industry is doing their part to help solve the locust problem... I bet those engines are an efficient way to reduce the population.

OP: Welcome to A.net Nightdesigns

The captain was brave enough to clean the windshield by hand. Without this window cleaning bravery, it would be nearly impossible to land with zero visibility. I thought like cars, planes also had a windshield water sprayer, although with some additives and heater to prevent freezing.

What windshield wiper/washer combo have your ever seen that would clean that quantity of squished insects? Even if a plane has fluid it wouldn't help for that.

No. There is no “washer fluid” type dispersal system to clean windshields.

In the “old days” aircraft used to have spray Rain Repellent that made it easier to see during heavy rain events. But, we were warned that if sprayed on a dry windshield, it would cause an opaque smear. Today, windshields are coated with a water repellent “permanent” coating.
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!

I’d guess they were going below that. I think landing speed is 175ish but they can fly slower than that. I think I’ve seen stall is 110 knots if you are in landing config so they could probably have gotten it down to 150 mph. Still a lot of wind but not quite as bad.

Creative thinking.

The root cause problem of all of this is that since the population is worried about chemtrails we really see the lotus population increasing. We need more chemtrails to keep us happy and to keep the lotus population under control.

I must admit I was thinking ‘yeah right’ on this tread, but the video does seem to corroborate this story.

I guess I'll join the "ilk" in questioning whether this was a good idea.

I wasn't there and maybe there were no other choices, but it does seem a bit dubious.

What other choices? I’m sure they didn’t have the option of pulling into a sky truck stop to have the windshield cleaned. Kudos to the crew for their innovative thinking, from the YouTube video it is clear visibility would have been zero if they didn’t do something.

I've landed with some pretty lousy fwd vis - are you sure it was truly zero or just severely limited?

There are many airliners where opening a window wouldn't be an option. What would they have done?

Sufficient quantities of insects can extinguish an engine, so not really something you want to try.

There is a view from inside of cockpit in the video above. I wouldn't be surprised if they didn't see runway at all.

No, but at least they're a little less crunchy than birds and their damn bones. The nerve of those birds having bones! They should be boneless.

The video shows that they had absolutely no visibility at all. Even though it is risky to clean the windshield in flight there arent many options. A landing with zero visibility is even more risky.

Could they not have landed on auto pilot?
And I thought runways had radar to help landings in poor visibility? Surely ADD has this?

Why did they fly through it in the first place ? I suspect that it was an ongoing and known risky situation where the flight shouldn't have gone. Is it not detectable on radar ?

But... and here's the most important question, did they get ATC permission to open their window </sarcasm>

Quick thinking. All ended well. Good job. I am little with Barney Captain (who is a very experienced 737 pilot) in wondering if there were other options. But assuming there weren't, very impressed with the improvising and creative thinking to increase the survivability odds of the situation.

So you are asking for a 100% perfect smear of insect parts, like fat, protein, intestines, liquids e.g. to cover the whole windshield? Without water, the wipers will not help, they will only perfect cover the windshield with this smear; you have to wash the insects away, but there is no wash-solution.

The Tristar had a windscreen washer, and rain repellent. You used the windscreen washer first, then the wipers, then gave it a dose of rain repellent.
Surprised that the washers did not last, they worked OK. But rain repellent was awful. The nozzles were always blocked, and hard to clean. Soaking in Coca Cola worked well!!

Autoland requires a CATIII ILS and an aircraft equipped to do it and a crew trained to do it.

A lot, if not most 737's don't have auto land. Southwest for example, flies CATIII hand flown.

This was an Ethiopian airlines crew, this was not the first incident with swarms of locusts for Ethiopian airlines, so pretty sure, the Ethiopian airline crews knows best, what they can do and what they shall better not do. As we can see in the video, the crew has not used the wipers. I am more than willed to accept, that the Ethiopian airline crew has done the job accordingly.

If you can't see through the windscreen, you do what you can.
In Bahrain in around 1979 we met a Iraqi Airways B737-200 that had diverted in.
It had taken off from DOH en route to Bagdad, and had flown through a thunderstorm. the capt said that there was a black line on the weather radar, that they assumed was a fault so they flew through it. The plane was hit by a hailstorm. All six cockpit windows were crazed and nearly opaque. The slats and leading edge of the tailplane was missing, and the nose cones of the engines were bent sideways. They diverted to BAH because we had an ILS, and used the autopilot to land the aircraft, opening the DV windows on finals to have a look.
A team of technicians arrived from Iraq, led by a fearsome young Iraqi lady and they changed the windows, and used filler and speedtape everywhere else and flew it back.

The pilots could not believe the damage.

I remember driving through Colorado one early summer during the breeding season for some kind of fly and my windshield got so schmutzed up that I had to stop three times in ten miles to scrape them off at a gas station. So I can only imagine what this would be like in an airplane flying through a biblical swarm of locusts.

Interestingly, insects have a much higher protein content (~80% by dry mass) than a bird (~40-50% by dry mass). Protein tends to get really sticky (which is why it's so awful if someone eggs your car).

Not forgetting BA9 coming back to KUL after the Volcanic ash induced in-flight shut down of all 4 engines, with the Windscreen effectively sandblasted with ash, not allowing any forward view.

Re: Ethiopian B737 opens cockpit window in flight, twice, to clear debris from windshield

This is actually SOP in at least some airliners. For example, I know the E-Jets and at least some A32X's have this as the last ditch procedure in the QRH if visibility is insufficient for landing and autoland is not available (which it never is in the E-Jets). I'm not sure of other airliners, but it may be SOP in the 737 as well. Usually there is a max speed given for it, but it's usually much higher than you'd be on final approach. Technically the procedure is to open the window and just look out, but it's probably safer to just try to clean the window than sticking your head out, and you're not going to rip your hand off at 150 knots.

How high an ARFF truck can shoot water? Maybe a low pass?


Not sure you've thought this one through, or even at all. How are you safely going to make a low pass - low enough for a firetruck to spray you with water, and directly over the truck - if you can't see? If you have the equipment, training, and certification to do that, why wouldn't you just land?

737 uses a full flaps and slow speed just like landing so the pilot is able to open window and wash front windshield as fast as he can best do. Copilot is flying so captain is washing the window then divert to airport arrive using ILS for safety reasons. Good job pilots.

I'm pretty sure at 8500ft they could deployed some flaps and reduces the speed to below 200 mph.

Maybe they could try an improved version of this ..

There have been many examples of aircraft safely landing with limited forward visibility. I'm glad this improvised technique worked out for this crew, I'm just not sure it's a path I would have taken. I've looked at the video and while certainly restricted, I'm not convinced there was zero forward visibility. The only approved procedure I'm aware of in Boeing aircraft is using goggles to look out the open L2 window - but staying safely out of the slipstream. You would never stick your head or any part of your body out of the window.

Here's the video - http://www.youtube.com/watch?v=dEMcD-RWA9A

The root cause problem of all of this is that since the population is worried about chemtrails we really see the lotus population increasing. We need more chemtrails to keep us happy and to keep the lotus population under control.


They should establish bird colonies around the airport to keep the locus population down...

So on the Dc-8 they would have to stick their arm out and clean the windows? No wipers on that aircraft!.

What other choices? I’m sure they didn’t have the option of pulling into a sky truck stop to have the windshield cleaned. Kudos to the crew for their innovative thinking, from the YouTube video it is clear visibility would have been zero if they didn’t do something.


Autoland?

I've landed with some pretty lousy fwd vis - are you sure it was truly zero or just severely limited?

There are many airliners where opening a window wouldn't be an option. What would they have done?


Autoland requires a CATIII ILS and an aircraft equipped to do it and a crew trained to do it.

A lot, if not most 737's don't have auto land. Southwest for example, flies CATIII hand flown.


If the airplane was capable of autoland, and not hand-flown CATIIIa as you mentioned, a CATIII ILS isn’t required. Any autoland equipped plane will autoland just fine with a vanilla CATI ILS. A CATIII is of course required if the airport is experiencing low visibility but this was a unique issue.

Heck, even if it was CATIIIa with HGS, you could still follow that down to a dead stop on the runway if need be. When I was at QX, I was paired with an upgrading captain and as an exercise to get him comfortable with the HGS, they had him fly all the way to a dead stop on the runway with zero visibility. When the brake was set, they raised the visibility and were dead on centerline every time. Pretty cool stuff.

But I have no idea how these 737s are equipped so none of that may have been an option, but if either of the above were, I’d take either option above scraping the windscreen in flight! Even if the plane was autoland capable but the operator wasn’t approved for it, that falls under emergency authority. But I wasn’t there so it’s easy to armchair quarterback from the comfort of my bed. :)
