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.

"..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.

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the warnings were rescinded after 6 seconds.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.

A little after that it indicates that the ground crew was supposed to
know about using pitot heat before performing their system checks, but
that information wasn't provided to this particular ground crew.


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."


What you suggest that the pilots may have done as a result of that
computer warning?

Abort takeoff?


Is that the appropriate response when the computer issues that warning
message?

It appears that they were just about to leave the runway when the
computer issued that warning.

Did adequate runway remain to abort the takeoff ?
