FAA Orders GE Engine Hose Replacements by August
Published Date: 7/17/2026
Rule
Summary
The FAA is making a new rule for certain General Electric GEnx engines because a fuel tube hose can leak and cause trouble. If you own or operate these engines, you’ll need to replace the faulty hoses with safe ones by August 21, 2026. This fix keeps flights safe and might cost some money but prevents bigger problems down the road.
Analyzed Economic Effects
4 provisions identified: 1 benefits, 3 costs, 0 mixed.
Mandatory fuel hose replacement
If you own or operate the listed GE GEnx engines, you must identify the preform manufacturing lot number of the specified fuel tube hoses at the next engine shop visit after August 21, 2026. If the lot number is 684141 or 677536, you must remove that hose before further flight and replace it with a part eligible for installation.
When work must be done
This AD is effective August 21, 2026, and requires identification of the listed hose lot numbers at the next engine shop visit after that date. The AD defines an "engine shop visit" as the induction of an engine into the shop for any maintenance, and if an affected lot number is found (684141 or 677536) the hose must be removed before further flight.
Estimated replacement costs
The FAA estimates this AD affects 13 engines on airplanes of U.S. registry. Estimated per-engine replacement costs range from $1,770 to $2,375 (including 8 work-hours at $85/hour); the FAA's summed cost on U.S. operators is $57,862 (listed as $24,211 + $26,125 + $3,540 + $3,986).
Certain lot-numbered hoses unairworthy
Any fuel tube hose listed in Table 1 with preform manufacturing lot number 684141 or 677536 (P/Ns 2426M07P01, 2426M08P01, 2477M34P01, 2477M35P01) is not eligible for installation and must be removed and replaced. The AD defines a "part eligible for installation" as any fuel tube hose that does not have P/Ns in Table 1 with preform manufacturing lot number 684141 or 677536.
