This document corrects a typographical error that appeared in airworthiness directive (AD) 2000-20-04 that was published in the Federal Register on October 6, 2000 (65 FR 59707). The typographical error resulted in the omission of the amendment number. This AD is applicable to certain McDonnell Douglas Model MD-90-30 series airplanes. This AD requires replacement of certain ground block screws with new screws; and retermination of the circuit ground wires of the electrical power control unit (EPCU) to separate grounding points.
