The crash on takeoff of a 509th Air Wing, Air Force B-2 Spirit
bomber, February 23 operating at Andersen Air Force Base, Guam,
was caused by water in the aircraft's sensors, according to an Air
Combat report issued Thursday.

"..in the end, the Air Force's report on the incident suggests the
entire accident could have been avoided..."


"..prior to the flight the aircraft's own systems had prompted the
crew to perform an air-data calibration.."


Pilot error?


* * The $1.4 billion aircraft crashed just off the left side of the
* * runway and exploded. It was the first-ever B-2 crash and followed
* * 75,000 hours of loss-free service. Link and Grieve both suffered
* * injuries during ejection, with Grieve suffering compression
* * fractures to his spine.

* * The report points to the inaccurate readings as contributing
* * factors, adding that ineffective communication of critical
* * information about a technique used to remove moisture from the
* * sensors also contributed. It's possible that all the pilots had
to


* * do to avert the accident was turn on the pitot heat prior to
* * performing air data calibrations. But the suggested technique was
* * not part of checklist procedures.

It sounds more like an incomplete checklist. *- Hide quoted text -


At the 2:00 mark of the video you posted, it states...

"Major Ryan Link and Captain Justin Grief? were warned by master
caution light and flight controls systems caution 19 seconds after
brake release while on take-off roll...". It then goes on to say that
the warnings were rescinded after 6 seconds.

I guess they should add to checklist...

"Step 38...when flying $1.4 billion aircraft and computer warns you
that something is wrong, listen to it."

A few months ago, was about to go riding on power trip were top speed
on my VFR-800 could reach 155 mph. As I was leaving parking lot, I
heard a faint clicking noise. It could have been anything, but
discipline dictated that I check, so I did. I found a nice, fat,
heavy- duty staple embedded in the real wheel rubber. Fortunately, it
was embedded at an angle that left the tread useable, but still, it
was there. If anything had happened, I would have had no one to blame
myself. I'd be lying in the hospital (or dead) saying, "Yeah, I did
hear this slight clicking noise coming from somehwere but I ignored it
because I had done a check-out less than 18 hours prior..."

Those pilots had more than a clicking noise. They had a computer
saying, "Something is not right".



You don;'t know that. You know they got a master caution, but you don't
know anything about the master caution system or the system it was
warning of. You know nothing of the porcendures and training involved
either.
