Airworthiness Directives; Rolls-Royce Deutschland Ltd & Co KG Engines
Published Date: 7/2/2026
Rule
Summary
If you own certain Rolls-Royce Deutschland Trent XWB engines, this new rule means you’ll need to check the main fuel hose more often for cracks, dents, or wear. Some engines require one-time inspections, while others need regular check-ups to keep flying safely. These changes start July 17, 2026, and could mean some repair costs if parts need replacing.
Analyzed Economic Effects
7 provisions identified: 6 benefits, 1 costs, 0 mixed.
One-time inspections required
If you own certain Rolls‑Royce Deutschland Trent XWB engines, you must do a one-time on-wing visual and dimensional inspection of the main fuel hose assembly to check for softness, shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire, and replace the main fuel hose assembly if necessary. The requirement is imposed through incorporation of EASA AD 2025-0128R1 and is effective July 17, 2026.
Repetitive inspections for other engines
For certain other Rolls‑Royce Trent XWB engines, the rule requires on-wing and in-shop repetitive visual and dimensional inspections of the main fuel hose assembly to check for softness, shrinkage, cracks, chafing, dents, kinks, necking, and degradation of the hose braid wire, and replacement of the main fuel hose assembly if necessary. These repetitive inspections are required as specified in EASA AD 2025-0128R1 incorporated by reference, effective July 17, 2026.
Optional terminating action available
The incorporated EASA AD provides an optional terminating action for the repetitive inspections: the repetitive checks end if the engine has passed an inspection with no findings (or findings are corrected) or if the engine has not yet reached the inspection threshold. That optional terminating action is part of the compliance material incorporated as of July 17, 2026.
Applicability expanded to more models
The AD expands applicability to include certain Rolls‑Royce Deutschland Model Trent XWB-75, Trent XWB-79, Trent XWB-79B, and Trent XWB-84 engines in addition to Trent XWB-97 engines, as identified in EASA AD 2025-0128R1. This expanded applicability is effective July 17, 2026.
No reporting requirement to manufacturer
Although EASA AD 2025-0128R1 specifies submitting certain inspection information to the manufacturer, this FAA AD does not include that reporting requirement. The FAA made this exception in the regulatory text effective July 17, 2026.
Installation allowed if serviceable and inspected
EASA AD 2025-0128R1 (incorporated by reference) allows installing an affected part on any airplane if the part is serviceable, and allows installing an affected engine if the engine passed the required inspections or findings were corrected. The FAA AD incorporates that material (with limited exceptions) effective July 17, 2026.
No U.S. compliance costs asserted
The FAA states there are no costs of compliance with this AD because there are no engines with this type certificate on the U.S. Registry. That statement appears in the Costs of Compliance section of the AD.
