CI120 Fire At Okinawa

Sat Dec 15, 2007 7:37 pm

previous threads are now archived but on History Channel Shockwave they interview a USAF doctor who was a passenger on the plane and sitting right above the wing- they could feel the heat in the cabin and the windows were cracking before the evacuation began, show also said the bolt which caused the fuel tank puncture was "vibrated " loose. Has anyone seen anything recently from the investigation to confirm this??

It was confirmed by the investigation. Also, the show was wrong the 737 was NOT grounded worldwide. An AD was issued to inspect the suspected area. A few other cases were found and corrective action was taken

Why would the windows crack? Cabin windows are made of stretched acrylic and stretched acrylic shrinks when it is heated.

I think you answered your own question.

The material shrinks and since it is secured around it's perimater that extra stress ends up cracking the material.

forgive me but let me get this straight, are you saying the loose bolt on this plane was out of position because it did "vibrate" loose . earlier reports suggested the problem may either have been because they were improperly installed at previous maintenance, or in some cases with other planes which were new, at manufacture.

was the CI planes problem because of mx issues (the washer or whatever hadn't been put back on) which made it vibrate loose or it loosened because of design issues despite having been put back together properly??

Actually they would shrink and fall out as the only thing holding the window in place is a rubber seal and a some spring clips. Windows have to be free floating so they don't crack during pressurization of the fuselage.

It was wrong from installation at the factory at Boeing. The China plane was brand new.....

B18616 was delivered in 02, there was at least a NH plane which was new with the problem.
