Summary

Mandatory Inspections for Boeing 787 Seat Tracks
Operators of certain Boeing Model 787-8, 787-9, and 787-10 airplanes must inspect seat tracks above the electronics equipment (EE) bays for missing, damaged, or deteriorated sealant, moisture barrier tape, or tape dams, and perform any required on-condition repairs. The Federal Aviation Administration issued this airworthiness directive to require those inspections and fixes to address potable water leakage into EE bays.
Reduces Risk of Electronics Damage from Leaks
The rule addresses reports of potable water leaking into electronics equipment (EE) bays caused by improperly installed waterline couplings and requires actions to stop that leakage. By stopping water intrusion into EE bays, the AD aims to reduce the risk of water-related damage to essential aircraft electronics and improve flight safety for passengers and crew.
