FAA Issues AW139 Control Rod AD

FAA has published an airworthiness directive (AD) for the AgustaWestland AW139 that requires operators to verify that the connection between the collective control rod C2 and the torque tube C3 is properly installed. The inspection is required within five hours time-in-service or seven days, whichever comes first. The AD seeks to remedy a potentially "unsafe condition" after discovering a case of a collective control rod being installed incorrectly. The inspection includes the bolt, the washer under the bolt head, the self-locking nut and its underneath washer, and a cotter pin. Maintenance technicians can strengthen the connection between C2 rod and C3 tube by using a maximum of two washers under the self-locking nut, according to the AD, which takes effect on July 3. FAA is seeking comments on the AD until August 17, 2012. Comments may be sent to the Federal eRulemaking Docket at www.regulations.gov, by fax at 1-202-493-2251 or mail to the U.S. Department of Transportation, Docket Operations, M-30, West Building Ground Floor, Room W12-140, 1200 New Jersey Avenue SE., Washington, DC 20590-0001.
