SUMMARY: We have received reports of parts of the main
slat track downstop assembly coming off the main slat track. In one
case, a nut fell into the slat track housing (referred to as "slat
can") and, during a subsequent slat retraction, the track made
contact with the nut, pushing it into the wall of the canand
puncturing it.
