THEIR BRAND-NEW AIRCRAFT THAT
CRASHED IN INDONESIA.

MAX 8 THAT WENT DOWN IN
INDONESIA.

THE WAY THAT THE PLANE FLIES
THROUGH.
THROUGH.
THROUGH. IT IS CALLED THE ANGLE OF
ATTACK.

FRONT THAT CAN CONTROL WHAT
HAPPENS HERE IN THE BACK IN
THEY'RE WORRIED ABOUT A FALSE
SIGNAL.
SIGNAL.
SIGNAL. >> Reporter: ALMOST EVERY
AIRPLANE WE SAW IS A 737 MAX.
THERE IS A TINY INSTRUMENT THAT
YOU PROBABLY HAVE NEVER NOTICED
BEFORE.
BEFORE.
BEFORE. ON THE NOSE, THERE IS A WING
LIKE DEVICE AS THE AIR GOES
PAST IT, THE SENSOR MOVES UP
AND DOWN WITH THE WIND.
IT IS CALLED, AOA, ANGLE OF
ATTACK.
ATTACK.
ATTACK. THE STABILIZER IS DESIGNED TO
MOVE AND IT HELPS THE AIRPLANE
FLY BETTER AND IT COMPENSATES
FOR AN AIRPLANE THAT MAY BE TOO
HEAVY IN THE FRONT OR BACK
SOMETHING CALLED KOTCHMAN.
THERE IS -- THE FRONT AND BACK
CALLED, TRIM.
CALLED, TRIM. THE FAA SAYS THAT THIS COULD
LEAD TO AN EXCESSIVE NOSEDOWN
ATTITUDE, SIGNIFICANT ALTITUDE
LAWS AND IMPACT WITH TERRAIN.
THAT IS WHAT WAS INDICATED IN A
2-MONTH-OLD AIRPLANE THAT WAS
FLOWN IN OCTOBER.
THE AIRPLANE NOSED OVER AND
HEADED STRAIGHT FOR THE JAVA SEE
AND KILLED EVERYONE ON BOARD.

AND AMERICAN. >> THE MAX IS NEW BUT WHAT
ABOUT THE OTHER 737S OUT THERE?
>> THAT IS THE QUESTION WE ARE
TRYING TO GET ANSWER.
AS WE LOOK AT THE SENSOR
LOCATED ON THE MAX, RIGHT HERE,
THERE WAS ANOTHER ONE HERE THIS
PIECE LOOKS TO BE THE SAME.
MAYBE THERE IS A DIFFERENT WAY
WITH THE PROCESSING, VERSUS THE
NEXT GENERATION AIRPLANE, WE
ARE WAITING ON AN ANSWER FROM
BOEING ON THAT.
>> WHAT WE KNOW ABOUT THE
SENSOR AND THE ROLE WITH THE
MOST RECENT CRASH?
>> THE ANSWER IS, WE DO NOT
KNOW.
KNOW.
KNOW. THIS IS A TYPICAL THING THAT
FORCES AIR SAFETY, WHEN YOU ARE
GOING ALONG THERE, I HAVE NO
DOUBT THAT BOEING'S ENGINEERS,
THE MINUTE THAT THEY SAW THEIR
PLAYING GOING LIKE THIS AND
THAT, IMMEDIATELY WENT TO WORK
TO FIGURE OUT, DID WE MISS
SOMETHING?
SOMETHING? WHAT COULD HAVE POSSIBLY
HAPPENED HERE?
