The Boeing Company Airplanes
This AD applies to The Boeing Company 727-100 Series, 727-100C Series, 727-200 Series, 727-200F Series, 727 Series, 727C Series.

This amendment supersedes an existing airworthiness directive (AD), applicable to all Boeing Model 727 series airplanes, that currently requires repetitive inspections to detect cracks in the slat track roller bearing bolts, and replacement, if necessary. This amendment adds an inspection of the positional plates installed on certain airplanes, and replacement, if necessary; reduces the compliance time for the initial inspection; and cites the latest revision to the service bulletin as the appropriate service information source. This amendment is prompted by a report that certain positional plates may not stop rotation of the roller bearing bolts. The actions specified by this AD are intended to prevent jamming of the affected slat or separation of the slat from the airplane.
