Most of you may have already complied with this AD, but just in case you haven’t, here's the deal.
This AD was effective June 25, 2010, and requires that SB 100-31-284 be complied with, within 250 hours of the effective date of the AD. This SB changes the Cabin Door annunciator to a red light and adds an amber annunciator light that reads "Cabin Door Seal." This allows the door seal pressure to be monitored separately from the mechanical locking system.
This AD applies to all Astra/G-100 aircraft, except S/N 158.
