Helicopter Window Jettison Rules Updated by FAA
Published Date: 6/4/2026
Rule
Summary
If you fly an Airbus Helicopters Model H160-B with a special window system, this new rule kicks in July 9, 2026. You’ll need to remove and inspect the jettisonable windows, fix or replace parts if needed, and keep lubricating and testing the system regularly. These steps keep your helicopter safe and stop certain window covers from being installed unless they meet new rules—so plan for some maintenance time and possible costs.
Analyzed Economic Effects
4 provisions identified: 0 benefits, 4 costs, 0 mixed.
Potential on-condition replacement costs
If inspections find discrepancies, you may need to replace locking-finger kits or install missing retaining rings. The FAA estimates replacing locking fingers can cost $4,540 per kit (including up to 12 work-hours) and installing a missing retaining ring can cost up to $135 per ring.
Mandatory window removal and inspections
If you operate an Airbus Helicopters Model H160-B modified by STC SR00223IB, starting July 9, 2026 you must remove and inspect the six jettisonable windows and, depending on findings, replace locking fingers and install any missing retaining rings and inspect/repair the left- and right-hand covers. The FAA estimates the remove-and-inspect action costs $16,320 per helicopter and the rule applies to eight U.S.-registered helicopters.
Cover modification and installation ban on some parts
Starting July 9, 2026 you must modify the helicopter by replacing each left- and right-hand cover and you may not install certain aesthetic cover part number 6A6H5600A002001XYZ or electrochromic window part number 6A6H5600A001001XYZ unless specific requirements are met. The FAA estimates the cover modification costs $920 per helicopter (2 covers) and estimates the rule affects eight U.S.-registered helicopters.
Repetitive lubrication and functional tests
If your H160-B (STC SR00223IB) has the affected jettisonable window system, you must perform repetitive lubrication of the locking fingers and an operational (functional) test after each lubrication starting July 9, 2026. The FAA estimates each lubrication action costs $170 per helicopter and each operational test costs $170 per helicopter.
