About

A certification practice, engineered for the next generation of aerospace and defense.

KTS Capital is a certification and airworthiness consultancy serving civil and military aircraft programs, manned and unmanned.

Programs

Where we work

01

Clean-sheet aircraft programs

Early certification basis development, applicability analysis, and identification of the special conditions and novel-technology findings a new configuration will require, during the conceptual design phase.

02

Derivative and modification programs

Amended and Supplemental Type Certificate planning, changed product rule analysis, and scoping of what the change pulls into the certification basis.

03

Equipment and systems suppliers

Requirements decomposition, development assurance planning, and qualification strategy for airborne equipment, including assessment of prior qualification evidence against the requirements of a new installation.

04

Flight authorization

Securing authorization to fly by whatever route the program allows — type and special airworthiness certificates, military type certificates, flight releases, and permits to fly — together with the substantiating data behind each.

Engagement process

How an engagement begins.

The consultation process is simple, straightforward, and carries no commitment until a statement of work is signed.

01

Scoping call and NDA

A short conversation about the program, where it stands, what is blocking it, and what approval or approvals are being sought. A mutual non-disclosure agreement will be in place before anything proprietary or export-controlled is shared.

02

Written assessment

A brief document detailing the recommended strategy and what should be addressed first. The assessment provides enough detail to make a determination on moving forward.

03

Proposal and statement of work

A scoped engagement with defined deliverables and agreed-upon terms: advisory, embedded, or a discrete deliverable, depending on the work required.

Who you work with

Kellen Dorsey, Founder and Principal of KTS Capital LLC

Kellen Dorsey

Founder & Principal

Kellen Dorsey is an aerospace engineer and a Southern California native who has spent over a decade in aircraft certification and airworthiness. His work sits where engineering meets regulation: the legal structure of the airworthiness code, the precedents that govern how it is applied, and the creative compliance strategies that get unconventional designs approved.

His experience spans an unusually wide range for the discipline — manned and unmanned air systems, civil and military applications, fly-by-wire and conventional flight controls, certified under both Part 23 and Part 25. That range is the foundation of how KTS Capital approaches a program: with more than one viable solution, and the judgment to know which one is most feasible for the design.

That breadth is matched by depth in the disciplines beneath a certification argument: ARP4754B development assurance and requirements decomposition from aircraft to system to item, ARP4761A system safety, and equipment qualification strategy, including assessment of prior qualification evidence against DO-160G, DO-178C, and DO-254 requirements.

If it cannot be certified, there is no business case. Full stop.

He founded KTS Capital on a conviction formed early: an aviation concept is only as viable as what can be built, maintained, and certified. The hardest certification work belongs in planning, while the design can still absorb a change — not in detailed design, when the engineering is done.

The firm’s opening statement is Certification, delivered. The emphasis is deliberate. Not action, not process, not documentation, and not effort — results that lead to flight.
