Exhibit 10.1

SEPARATION OF EMPLOYMENT AGREEMENT AND GENERAL RELEASE

THIS SEPARATION OF EMPLOYMENT AGREEMENT AND GENERAL RELEASE (the “Agreement”) is made as of this 31st day of January, 2012, by and among Hawker Beechcraft Corporation (the “Company”), Hawker Beechcraft, Inc. (“HBI”), and James Maslowski (“Employee”).

WHEREAS, the Company has notified Employee that he is being terminated by the Company effective January 31, 2012 (the “Termination Date”); and

WHEREAS, in connection with Employee’s termination of employment, the parties have agreed to the terms set forth herein;

NOW, THEREFORE, IT IS HEREBY AGREED by and among Employee, the Company and HBI as follows:

1. Employee at Will; Termination: Employee has been an employee at will and on September 4, 2007, at the time he accepted his offer of employment, he acknowledged and agreed that he could be terminated by the Company at any time, for any reason, with or without notice. Effective as of the Termination Date, Employee accepts his termination by the Company without Cause (as defined in the RSU Agreement).

2. Final Paycheck and Accrued Vacation: The Employee shall receive any payroll amounts earned, accrued or owing but not yet paid to Employee up through and including the Termination Date, including, but not limited to any benefits accrued or earned, which will be distributed in accordance with the terms of the applicable benefit plans and programs of the Company. The Employee shall receive any vacation time earned but not yet paid to Employee up through and including the Termination Date, according to the Exempt Employee Vacation Policy existing as of the Termination Date.

3. Vested RSUs: Pursuant to the Restricted Stock Unit Agreement between HBI and Employee dated August 9, 2011 (the “RSU Agreement”), Employee received 97,143 HBI Restricted Stock Units (“RSUs”). As a result of Employee’s involuntary termination without Cause, as stated herein, Employee is entitled to the issuance of 43,429 shares of common stock of HBI (“Shares”) in exchange for his 43,429 Accrued RSUs (as defined in the RSU Agreement) pursuant to Section 4.1 of the RSU Agreement. In addition, in recognition of Employee’s service, the HBI Compensation Committee has approved the accelerated accrual of an additional 19,429 RSUs. Employee is entitled to the issuance of 19,429 Shares in exchange for these additional 19,429 Accrued RSUs pursuant to Section 4.1 of the RSU Agreement. All other RSUs held by Employee other than the 62,858 Accrued RSUs are null and void, and no Shares will be issued in exchange for any such RSUs.

4. Fringe Benefits: Your company-sponsored medical, dental, vision, life insurance, and flexible spending account (if participating) benefits will remain active through January 31, 2012.

Page 1

Your participation in all other company-sponsored benefit plans will cease effective January 31, 2012. Employee is not eligible to participate in an employer-sponsored medical plan after January 31, 2012, therefore COBRA benefits will be made available at that time for a period not to exceed eighteen (18) months. Employee’s 401(k) contributions as well as the company match will cease effective January 31, 2012.

5. Management Incentive Plan (“MIP”): Employee will be eligible to receive a MIP Bonus for 2011, but only to the extent his performance and the financial results for the Company for the relevant time period trigger a bonus strictly in accordance with the terms of the MIP. Payment of the bonus will be made in a lump sum amount, subject to normal statutory withholding, on the same payroll date as other employees receive payment. Employee will not be eligible to participate in the MIP for 2012.

6. Reduction of Separation Benefits: The Company and HBI each reserve the right to make deductions in accordance with applicable law for any monies owed to the Company or HBI, respectively, by the Employee.

7. Release and Representations:

(a) Employee, for and in consideration of the commitments of the Company and HBI as set forth in paragraphs 2, 3, 4, and 5 of this Agreement, and intending to be legally bound, does hereby REMISE, RELEASE AND FOREVER DISCHARGE the Company, HBI, and their respective affiliates, subsidiaries, parents, officers, directors, employees, and agents, and their respective successors and assigns, heirs, executors, and administrators (collectively, “Releasees”) from all causes of action, suits, debts, claims and demands whatsoever in law or in equity, which Employee ever had, now has, or hereafter may have, whether known or unknown, or which Employee’s heirs, executors, or administrators may have, by reason of any matter, cause or thing whatsoever, from the beginning of Employee’s employment through the Termination Date, and particularly, but without limitation of the foregoing general terms, any claims arising from or relating in any way to Employee’s employment relationship with the Company, Hawker Beechcraft Defense Company, LLC (“HBDC”) and/or HBI, the terms and conditions of that employment relationship and the termination of that employment relationship, including, but not limited to, any claims arising under the Age Discrimination in Employment Act, the Older Workers Benefit Protection Act (“OWBPA”), Title VII of The Civil Rights Act of 1964, the Americans with Disabilities Act, the Family and Medical Leave Act of 1993, the Employee Retirement Income Security Act of 1974, the Rehabilitation Act, the Fair Labor Standards Act (29 U.S.C. 201 et seq.), the Kansas Act Against Discrimination (K.S.A. 44-1001 et seq.), the Kansas Age Discrimination in Employment Act (K.S.A. 44-1111 et seq.), the Kansas Wage Payment Act (K.S.A. 44-313 et seq.), and any other claims under any federal, state, or local common law, statutory, or regulatory provision, now or hereafter recognized including, but not limited to, breach of contract, unlawful retaliation, and defamation, and any claims for attorneys’ fees and costs.

In the event that suit is filed in breach of this covenant not to sue, it is expressly understood and agreed that this covenant shall constitute a complete defense to any such suit.

10. Consideration: None of HBI, HBDC, or the Company is under any obligation to pay Employee any consideration in respect of his termination, and no inference or admission of any type of wrongdoing by the Company can be made because the Company has offered any payments to Employee.

It is expressly understood and agreed that any breach or threatened breach of this paragraph by Employee shall constitute a material breach of this Agreement.
