Compliance required as indicated unless previously accomplished. To prevent jamming of the elevator controls by a detached forward rod end, accomplish the following:

A. Within the next 650 hours time in service or 90 calendar days, whichever occurs first after the effective date of this AD, visually inspect the fitting assembly (rod end) part number (P/N) 3938704-1 and pushrod P/N 3938705-501, in accordance with McDonnell Douglas DC-9 Alert Service Bulletin A27-266, dated March 12, 1984, hereinafter referred to as ASB27-266, or later FAA approved revisions.
