The Federal Aviation Administration issued Airworthiness Directive 2026-20-12 on 8 October 2026, effective 23 October 2026, mandating the replacement of 15 high‑pressure turbine inter‑stage seals on GP7270, GP7272 and GP7277 engines used on Airbus A380s.
Engine Alliance released technical service bulletin EAGP7‑A72‑479 on 4 September 2026 detailing the replacement procedure, and the FAA estimates the cost per seal at $527,300 for parts plus $850 labor, totaling $528,150 each.
Why it matters
The FAA notes that no engines on U.S.-registered aircraft are affected, so U.S. airlines will not incur direct costs.
