Fuselage Repaired CI 738 To Take Off Nearly Crash

Fri Oct 05, 2007 3:37 pm

NHK news says on 5 at 14:35 JST, China Airlines 737-800 made a nealy-crash take off at Saga Airport, which exceeded 2000m runway and went through over-run zone (sorry I don't know the exact term), hitting one of the ground lights to break.
Saga Airport is a local airport located in the western part of Japan with mainly domestic flights and several short-medium range international flights
Reportedly the speed meter went out of order, and returned back to the departed airport 30 minutes later.
I guess this made it impossible to make V1 and VR call at the exact timing.

This troubled 737-800 had found a crack of 77cm length in fuselage surface (close to below right horizontal fin) on 20 September, had been staying at the airport for repair until today, and should have gone back home to Taipei, Taiwan.

Here is the video from NHK, in which the take off is recorded.

"Uhhh, Co-pilot, did you remove the pitot tube cover before we taxied out?"

"Pitot cover? What pitot cover?"

I say it was masking tape left over the static port.

Okay - they lost the ability to check their air speed. That I believe.

But they took off from a short field runway - with Fukuoka 27 nm North and Nagasaki 24 nm SW - both with 3,000M runways - if they were in the air 30 minutes - they should have gone into an airport with a longer runway.

Does it really happen that either the pitot tube cover or masking tape is forgotten to remove?
Sure the aircraft has been on ground for two weeks and this should necessitates some protection for accurate sensors and engines against sandy, dusty and salty winds.
Also the airport is so local that mechanics are not usually stationed. Should it be removed by the mechanic or the pilot?

The pilot has the ultimate responsibility in making sure his airplane is airworthy. During his walkaround, he should have inspected the pitot tubes and static ports to verify they were clear of obstructions..

Surely an experienced pilot would have known the rough speed of the aircraft on the runway and would have judged when to pull back.

Why was it not noticed during the taxi as a speed is displayed whilst taxing?

What about the secondary indicator? Does that use the same equipment as the primary?

Surely happens,i still remember the Aeroperú´s 757-200 crashed in teh sea because the marking tape was forgotten to remove. A sad accident and that accident also made Aeroperú went bankrupt.

My question is, what flap setting did they use??

It appears to be flaps 1, which evidently was not enough. For a short runway Flaps 5 or 15 would have been appropriate. Oh well, at least they aren't a smoking hole.

the ground light upon over-run zone.

Slightly off topic, there was a report today that the primary cause of that crack was corrosion caused by a leaky aft galley water pipe.

Yes, there was a big accident in SA, i think its to late and im to tired to remember which airline was it, i think it was TAM, but I think i am mistaken, the AC just came out of maintenance, and the livery was red, and the tape on top of the static was also red, so the FO did not see the problem, they took off, saw that they had no correct altitude or speed and they crashed.

it runs on the same system.
