Advanced Aerospace Designs released Public Service Bulletin PSB-02-2018, which requires owners to send all Vigil II automatic activation devices with serial numbers from 16,000 to 21,999 to the manufacturer for inspection. After an AAD malfunctioned, the manufacturer traced the problem to an unreliable electrical connection. The company has inspected 200 units without finding a similar problem but has decided to check all of the affected units as a precaution. The PSB describes the process required for each affected unit. The inspection is mandatory, and owners should complete it at the next reserve repack or by no later than December 31, 2019. The company will also update the software and replace the battery, since the affected units are within two years of a required battery change. More information is available at
