227 US-registered aircraft fly this program — 562 installed engines across 13 registry codes
Program snapshot(US registry)
13 registry engine codes aggregated
No meaningful US teardown supply yet — 227 aircraft flying, median build year ≈2017; the retirement curve is the thing to watch.
FAA registry data, US-registered aircraft only. Deregs = domestic deregistrations — a teardown proxy that also captures re-registrations and some unflagged exports, never a confirmed part-out count. Median build year is a tails-weighted median of per-variant medians (≈). 17 of 227 active tails are registered under generic series codes rather than a specific variant, so per-variant splits are partial.

+ 1 more registry codes covering 1 active tails (each under 2 tails).
Counts reflect the engine model exactly as registered. Registry-wide, roughly 57% of engine records name a specific variant; the rest carry generic series codes, so generic rows coexist with variant rows and per-variant figures are partial. Deregs = domestic deregistrations (a teardown proxy, not confirmed part-outs); exported aircraft left the US fleet intact.
Airframe applications
FAA registry + BTS T-100 family rollups
| Family | Tails on this program | Family US fleet | Avg fleet age | Built 15+ yrs ago | Avg cycles / yr |
|---|---|---|---|---|---|
| 787 | 173 | 197 | 7.6 yr | 2 | 358 |
| 747 | 54 | 191 | 22.7 yr | 116 | 266 |
“Tails on this program” counts US-registered aircraft the registry rollup maps to both the family and a GEnx engine code — an undercount, since not every tail resolves to a family. Family fleet, age, and cycles columns describe the WHOLE family across every engine option, not just GEnx-powered aircraft (cycles from BTS T-100, 2025).
Airworthiness Directive activity

- FAA AD 2026-04-09effective Mar 11, 2026Mixed actions
The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model GEnx-1B64, GEnx-1B64/P1, GEnx-1B64/P2, GEnx-1B67, GEnx-1B67/P1, GEnx-1B67/P2, GEnx-1B70, GEnx- 1B70/75/P1, GEnx-1B70/75/P2, GEnx-1B70/P1, GEnx-1B70/P2, GEnx-1B70C/P1, GEnx-1B70C/P2, GEnx-1B74/75/P1, GEnx-1B74/75/P2, GEnx-1B76/P2, Genx- 1B76A/P2, GEnx-2B67, GEnx-2B67/P, and GEnx-2B67B engines. This AD was prompted by a report of a quality escape for certain high-pressure compressor (HPC) stage 5 blisks manufactured from a single forged ingot with a nonconforming indication. This AD requires replacement of certain HPC stage 5 blisks with parts eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model GEnx-1B64, GEnx-1B64/P1, GEnx-1B64/P2, GEnx-1B67, GEnx-1B67/P1, GEnx-1B67/P2, GEnx-1B70, GEnx- 1B70/75/P1, GEnx-1B70/75/P2, GEnx-1B70/P1, GEnx-1B70/P2, GEnx-1B70C/P1, GEnx-1B70C/P2, GEnx-1B74/75/P1, GEnx-1B74/75/P2, GEnx-1B76/P2, GEnx- 1B76A/P2, and GEnx-2B67/P engines. This AD was prompted by a manufacturer's investigation that revealed certain high-pressure turbine (HPT) stage 1 and HPT stage 2 disks were manufactured from powder metal material suspected to contain iron inclusion. This AD requires replacement of affected HPT stage 1 and HPT stage 2 disks with parts eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model GEnx-1B64, GEnx-1B64/P1, GEnx-1B64/P2, GEnx-1B67, GEnx-1B67/P1, GEnx-1B67/P2, GEnx-1B70, GEnx- 1B70/75/P1, GEnx-1B70/75/P2, GEnx-1B70/P1, GEnx-1B70/P2, GEnx-1B70C/P1, GEnx-1B70C/P2, GEnx-1B74/75/P1, GEnx-1B74/75/P2, GEnx-1B76/P2, GEnx- 1B76A/P2, GEnx-2B67, GEnx-2B67B, and GEnx-2B67/P engines. This AD was prompted by a manufacturer evaluation that determined a lower life limit may be necessary for certain stages 6-10 compressor rotor spools than allowed by the engine shop manual (ESM). This AD requires a one- time inspection of the stages 6-10 spools for previously accomplished blend repairs, a one-time inspection of the blend repairs on the stages 6-10 spools for compliance with the updated allowable limits, and replacement if necessary. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) Model GEnx-1B and GEnx-2B engines. This AD was prompted by a manufacturer investigation that revealed that certain stages 6-10 compressor rotor spools and forward seals were manufactured from powder metal material suspected to contain iron inclusion. This AD requires the replacement of the affected stages 6-10 compressor rotor spools and forward seals. The FAA is issuing this AD to address the unsafe condition on these products.

The FAA is adopting a new airworthiness directive (AD) for certain General Electric Company (GE) GEnx-1B and GEnx-2B model turbofan engines. This AD was prompted by a manufacturer investigation that revealed that certain high-pressure turbine (HPT) stage 2 disks, forward seals, and stages 6-10 compressor rotor spools were manufactured from powder metal material suspected to contain iron inclusion. This AD requires replacement of the affected HPT stage 2 disks, forward seals, and stages 6-10 compressor rotor spools. The FAA is issuing this AD to address the unsafe condition on these products.
Directives in the FAA / EASA corpus we have processed whose text names GEnx engine models — not a complete historical AD list, and text matching can include airframe directives that reference the engine. An AD is a compliance requirement that drives scheduled work on a regulator's clock — a regulatory compliance signal, not a failure prediction, and no comment on this engine's reliability.
