| Background: | The FAA received a report that a Model PA-28-181 aircraft crashed after the pilot lost control of the ailerons and elevator. Investigation revealed that the left control wheel single attachment screw had unscrewed from its nut plate, which resulted in the control wheel spinning freely on the control column. Further investigation revealed the screw was too short and the nut plate lacked proper locking characteristics.Amendment 1 is issued in response to the issue of a corrected copy of the related FAA AD, which corrects certain parts of the text. The only part requiring correction of this Directive was Requirement 1. text, “Part I of SB No. 1139 dated 9 April 2004” which was changed to “Part I of SB No. 1139A dated 9 April 2004”. |
