The May 1998 issue of Flightfax contained the first-person accounts of the crew of a CH-47 that did a barrel roll. As a result of that incident, Aviation Safety Action Message CH-47-98-ASAM-Ol (151327Z Oct 98) requested information from users on uncommanded control inputs. Input from users confirmed that this was not the only incident of uncommanded flight-control input experienced in the CH-47 community in the last several years. According to the Analytical Investigation Branch at Corpus Christi Army Depot, 21 activities responded to the ASAM, reporting 27 AFCS/electrical malfunctions, 4 hydraulic- related malfunctions, 4 unknowncauses, and suspected ice-and-water contamination incidents.
