AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Revise the maintenance program to incorporate Airworthiness Limitations No. 28-AWL-27 and No. 28-AWL-28. For airplanes with optional water system drain plumbing, install the new panel assemblies at an alternative location and change the interconnecting wiring between the P141 panel and the P36 and P37 panels. For airplanes with a deactivated center fuel tank, perform an alternative functional test for the left and right override/jettison pumps.
