FAA Proposes Fixes for Water-Leaking Connectors on Gulfstream Jets

## Summary

The FAA wants Gulfstream G280 airplane owners to fix a problem where water gets into electrical connectors near the tail, causing warning messages during flight. They’re proposing a retrofit to the flight control wiring to keep things safe and sound. Comments on this plan are open until February 23, 2026, so owners should get ready to act soon and budget for the update.

## Abstract

The FAA proposes to adopt a new airworthiness directive (AD) for certain Gulfstream Aerospace LP (GALP) Model Gulfstream G280 airplanes. This proposed AD was prompted by reports of the accumulation of water in electrical connectors located in the aft fuselage directly below the empennage, resulting in empennage flight control related crew alerting system (CAS) messages. This proposed AD would require retrofitting the flight controls empennage electrical harness. The FAA is proposing this AD to address the unsafe condition on these products.

## Effects PRIA read

- G280 owners must retrofit wiring: cost, high. If you own or operate a Gulfstream G280 airplane, the FAA proposes you must retrofit the empennage flight controls electrical harness to stop water getting into connectors. The FAA estimates the retrofit takes 80 work-hours (at $85/hour = $6,800) plus $3,200 in parts, for a total estimated cost of…
- FAA removes manufacturer reporting: benefit, low. The FAA's proposed AD does not include the CAAI AD's instruction to submit certain information to the manufacturer, so you would not have to provide that manufacturer reporting. This reduces an administrative reporting requirement that the foreign CAA had included.
- Warranty may reduce out-of-pocket: benefit, low. The manufacturer says some or all of the retrofit costs may be covered under warranty, which could lower or eliminate your out-of-pocket expense for the required work. The FAA notes this as a possibility but does not specify amounts or conditions for warranty coverage.
