FAA Proposes Fixes for Water-Leaking Connectors on Gulfstream Jets
Published Date: 1/7/2026
Proposed Rule
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.
Analyzed Economic Effects
3 provisions identified: 2 benefits, 1 costs, 0 mixed.
G280 owners must retrofit wiring
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 $10,000 per airplane and an aggregate cost of $1,400,000 for 140 U.S.-registered airplanes.
FAA removes manufacturer reporting
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
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.
