Re: UA328 engine explosion at DEN

So is the theory that the blade(s) went into the engine and then came back out the front (i.e. passed back through the fan) and sliced the cowling on the way out? How would it not damage other blades when passing back through the fan? I think the fan blade separated and was ejected forward, damagin...

Re: UA328 engine explosion at DEN

When you say cowlings do you include the intake ring? If so, no engine is ever run without an intake. Development engines do run with slave intakes during some tests but fan blade off tests have to be run with the production flight intake fitted. The cowling doors are not usually fitted for fan bla...

Re: UA328 engine explosion at DEN

On a new engine in development, this wouldn’t constitute a fan blade off test pass. I’m not sure how they will argue these engines are airworthy without a design change to the fan casing. A fan blade off needs to be a non-hazardous failure due to the frequency being above the allowable threshold fo...
