>>> f.a.a. has ordered more than a thousand, mostly late model boeing 737s to be examined to see if a part of the planes' tails need to be replaced. specifically it's a pin that holds the horizontal stabilizer which the pilots use to control the pitch of the aircraft. the potential defect has not caused any accidents. f.a.a. says there is no immediate threat. if that were the case they say the planes would all be grounded and nothing close to that is happening.
