1.A., EFFECTIVITY. IF AN AIRPLANE HAS BEEN LEASED OR SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OPERATOR. IF APPLICABLE SPARES HAVE BEEN SOLD, SEND THIS SERVICE BULLETIN TO THE NEW OWNER.
CONCURRENT REQUIREMENTS Refer to Paragraph 1.B., Concurrent Requirements.
BACKGROUND This service bulletin gives instructions to remove and replace the P1-3 and P3-1 instrument panels in the flight compartment with panels that include two warning level indicator lights. These indicator lights read "TAKEOFF CONFIG" and "CABIN ALTITUDE". The installation of these lights will provide a visual indication to the flight crew in addition to the existing aural warning horn for cabin altitude and takeoff configuration alerts. The visual warning lights are intended to provide an additional indication to crews to prepare a correct takeoff configuration, respond to excessive cabin altitude and avoid confusion between the takeoff configuration and cabin altitude alerts. An unrecognized incorrect takeoff configuration or excessive cabin altitude could prevent a continued safe flight and landing.
