Honeywell and Flexjet have reached a settlement resolving long-running litigation and have agreed to extend their aircraft engine maintenance agreement through 2035.
The settlement resolves all pending claims between Honeywell and Flexjet, as well as related litigation involving StandardAero and Duncan Aviation. As part of the agreement, the companies said they plan to rebuild their commercial partnership and work collaboratively moving forward.
"Honeywell and Flexjet are pleased to have reached a comprehensive agreement to resolve their pending litigation and look forward to rebuilding the parties' commercial partnership," Honeywell said in a release on Tuesday.
"This agreement places supplier accountability at center stage, and we hope it further unites the industry around a matter essential to private aviation operators both large and small," a Flexjet spokesperson said in a statement sent to GlobalAir.com. "With a value surpassing a billion dollars in cash considerations and service credits, it sets a powerful precedent for businesses seeking to correct similar supplier transgressions. Our hope is that the litigation and now agreement serve as a case study reinforcing the importance of supplier relationships built on authentic commitment, principled conduct, and consistent delivery."
Flexjet sued the aerospace giant in March 2023, alleging a breach of the parties' aircraft engine maintenance services agreement and seeking liquidated damages tied to delayed engine repairs, according to a December 2025 Form 8-K filed by Honeywell with the Securities and Exchange Commission.
In that filing, Honeywell said it was engaged in settlement negotiations and expected to record a one-time charge in its Aerospace Technologies segment in the fourth quarter of 2025. The company estimated the charge would reduce GAAP sales by about $310 million and operating income by about $370 million, reflecting contra-revenue accounting. Honeywell also said it expected any comprehensive settlements to include one-time cash payments totaling approximately $470 million in aggregate, noting the figures were subject to change based on final terms and that no assurance of settlement could be given at the time.
The newly announced agreement extends the engine maintenance contract through 2035 as partial consideration for resolving the disputes, the companies said.
