Opinion

IN THE UNITED STATES DISTRICT COURT FOR THE DISTRICT OF KANSAS

TEXTRON AVIATION INC.,

Plaintiff,

v. Case No. 6:25-cv-01088-HLT-ADM

WILLIAM TSUMPES, et al.,

Defendants.

MEMORANDUM AND ORDER This case stems from a failed deal for an aircraft. Plaintiff Textron Aviation Inc. sued Defendants William Tsumpes and Seaguard Aviation, LLC for breach of contract and declaratory relief. Textron seeks liquidated damages based on Defendants’ failure to complete the deal. Defendants move to dismiss. Doc. 42.1 They dispute personal jurisdiction and the existence of an enforceable contract. The Court denies the motion. Defendants purposefully availed themselves of this forum when they came to Kansas to execute the deal and help design the aircraft. And the Court can’t resolve the question of whether the contract is binding at the pleading stage. Textron has plausibly stated its claims. Defendants also move to strike Textron’s withdrawal of a demand for a jury trial. Doc. 44. Given the open question in this case about the enforceability of the contract (which includes a jury waiver), the propriety of the jury demand is not clear. This matter therefore can’t be decided at the pleading stage. Defendants will not be prejudiced by Textron’s withdrawal of the demand. The Court therefore denies the motion.

1 Defendants request oral argument. The Court denies that request because it would not materially assist the Court in deciding the motions. I. BACKGROUND2 Textron is an aircraft manufacturer. Doc. 31 at ¶ 1. Tsumpes is an individual. Seaguard is a limited liability company whose members are Tsumpes and another entity whose sole member is also Tsumpes. Id. ¶¶ 2-3. Tsumpes is a Texas resident, and Seaguard is a Montana limited liability company. Id.

Textron entered into an Aircraft Purchase Agreement (“APA”) with Tsumpes for the purchase of an aircraft. Id. ¶ 8. Part 1 of the APA identified the purchaser as “William Tsumpes an individual.” Id. Tsumpes signed the APA and noted his title was “CEO.” Id. ¶ 8. Tsumpes made the first deposit of $250,000 on May 1, 2024. Id. ¶ 11. On May 23, 2024, Tsumpes traveled to Textron’s factory in Kansas to make interior and exterior design choices for the aircraft. Id. ¶ 12. During that visit, Tsumpes wet signed and dated the APA.3 Id. On May 24, 2024, Tsumpes made a second deposit of $500,000. Id. ¶ 13. In June and July 2024, Tsumpes and Textron’s customer account manager corresponded about the interior design of the aircraft. Id. ¶ 14. The APA contains a forum selection clause stating that “any dispute arising under, out of

or related in any way to this Agreement, the legal relationship between Seller and Purchaser, or the transaction that is the subject matter of this Agreement” will be governed by Kansas law and will be adjudicated in Kansas federal court or Kansas state court. Doc. 24 at 12. It also states that the parties consent to personal jurisdiction of those courts. Id.; see also Doc. 31 at ¶ 5. Article 6(b)

2 The following facts are taken from the well-pleaded allegations in the amended complaint and are presumed to be true for purposes of this order. See Doc. 31. The APA has been submitted as an exhibit, see Doc. 24, and both parties agree it is properly considered. Doc. 43 at 2 n.1; Doc. 49 at 1 n.1; see also GFF Corp. v. Associated Wholesale Grocers, Inc., 130 F.3d 1381, 1384 (10th Cir. 1997) (“[I]f a plaintiff does not incorporate by reference or attach a document to its complaint, but the document is referred to in the complaint and is central to the plaintiff’s claim, a defendant may submit an indisputably authentic copy to the court to be considered on a motion to dismiss.”). 3 The APA signature page has the date of Tsumpes’s signature as April 30, 2024. Doc. 24 at 15. It’s unclear if this discrepancy arose from electronic versus wet signatures. states that if the purchaser fails to take delivery of the aircraft or fails to perform obligations under the APA, it will be considered a “pre-delivery breach” and Textron will be entitled to liquidated damages equal to all paid deposits as well as all remaining deposits due. Doc. 31 at ¶ 9; see also Doc. 24 at 10. The APA was first amended on July 29, 2024. Doc. 31 at ¶ 15. Amendment No. 1 made

the third deposit of $750,000 due by September 15, 2024. Id. Tsumpes signed the amendment, again using the title of CEO, but with no reference to Seaguard. Id. Tsumpes did not make the third deposit of $750,000 by September 15, 2024. Id. ¶ 17. On September 25, 2024, Tsumpes acknowledged notice of the past due deposit. Id. ¶ 18. On September 26, 2024, Textron sent Tsumpes a Default Notice with a cure deadline of close of business the next day. Id. Tsumpes responded and proposed installment payments for the remainder of the deposit. Id. The proposed installment dates and amounts were $350,000 due on September 27, 2024, which Tsumpes paid on that date, and $400,000 due on November 25, 2024. Id. The parties memorialized these changes in Amendment No. 2. Id. Tsumpes signed Amendment

No. 2 on October 31, 2024, and listed his title as “Himself.” Id. ¶ 20. On that same day, the parties also executed Amendment No. 3. Id. ¶ 21. Amendment No. 3 revised the sales allowance, updated the interior and exterior schemes, added various features, and added interior and exterior renderings. Id. Tsumpes signed Amendment No. 3 and listed his title as “Himself.” Id. The final $400,000 deposit was not paid by November 25, 2024. Id. ¶ 22. Textron sent a past due notice to Tsumpes on December 11, 2024, who requested an extension until January 24, 2025. Id. Textron accommodated this request. Id. Up until this point, all dealings were between Textron and Tsumpes individually. Id. ¶ 24. None of Tsumpes’s correspondence included a signature block for Seaguard. Id. On February 25, 2025, Tsumpes traveled to Textron’s factory in Wichita to execute Amendment No. 4, in which Tsumpes assigned the APA to Seaguard. Id. ¶ 25. By that assignment, Seaguard agreed to assume all rights, liabilities, and obligations of Tsumpes under the APA.

Id. Article 3 of Assignment No. 4 stated: If Assignee [Seaguard] does not fully and completely perform all obligations of Assignor [Tsumpes] under the Agreement [APA], then, in accordance with the terms and conditions of the Agreement, Assignor and Assignee are both jointly and severally responsible for any and all damages arising from any breach of the Agreement and Seller [Textron] may pursue both or either party for full satisfaction.

Doc. 24 at 26. Tsumpes signed Amendment No. 4 on February 25, 2025, using the title “Himself,” and he also signed for Seaguard as “Member.” Doc. 31 at ¶ 26. Tsumpes was physically present in Kansas when he signed. Id. Amendment No. 5 was also executed on February 25, 2025. Id. ¶ 27. This amendment reflected that the remaining $400,000 deposit was due by January 24, 2025. Id. Amendment No. 5 was signed by Tsumpes on behalf of Seaguard. Id. ¶ 28. The $400,000 deposit had not been paid on January 24, 2025. Id. ¶ 29. But Textron agreed to accept the final deposit at the time of delivery, along with the remaining balance due. Id. The aircraft delivery date under the APA was April 30, 2025. Id. ¶ 31.4 Tsumpes and Seaguard told Textron they would not take delivery of the aircraft on that date. Id. ¶ 32. Textron has fully performed its obligations under the APA, including all five amendments and presenting

4 Defendants argue that the “Ready for Delivery” date in the APA and the “Delivery Date” are listed as the “Fourth Quarter of 2024.” Doc. 43 at 3; see also Doc. 24 at 4. the aircraft for delivery as defined in the APA. Id. ¶ 34. Based on this, Textron contends Tsumpes and Seaguard are in pre-delivery breach under the APA. Id. ¶ 33.
