Among these services are specialized contract consulting, project management, fixed & rotary wing modifications, prototyping and discrete research & development on civil, military and governmental aircraft.

Our people and the trusted relationships we have developed over the many years of working with domestic and foreign governmental authorities who regulate the aerospace industry are the primary key to our success.

ACE (Aircraft Certification Engineers)

Kestrel Certification Engineers are high level technical inspectors and who have a demonstrated practical background in applied engineering modifications, alterations and repairs. They are experienced in providing field approval services, conformity and regulatory compliance while working closely with Federal Aviation Administration principal inspectors.


Certification engineers are typically graduates of an accredited aviation technical college or university. Most are certificated by the Federal Aviation Administration as an Airframe & Powerplant technicians.Senior certification engineers, in addition to the basic qualifications, typically hold FAA inspection authorization privledges and have more extensive experience with STCs, field approvals*, conformity and regulatory compliance while working closely with Federal Aviation Administration principal inspectors.

*FAA field approval facilitates approval of systems & equipment installations within their authority, AFMS (aircraft flight manual supplementation) and ICA (instructions for continued airworthiness) and non-complex alterations not requiring development of a supplemental type certificate.
Damage Tolerance/Fatigue
Analysis is accomplished by specially authorized aerospace engineers who use Federal Aviation Administration approved damage tolerance methodologies for pressure vessel penetrations.

Most professionals would agree that effective program management has a critical role in attaining successful results and their involvement should start well before the work begins.

A common paradigm we have found directly associated in many competent organizations would be that program management functions and responsibilities are often considered synonymous with those of project management. Both are quite similar in the preliminary execution phases however; the mixing of macro and micro management functions in critical phases typically evolves into crisis management, delays and loss. In some cases we have found that critical program managerial duties and responsibilities are relegated to someone who has not developed or mastered the skills to properly manage at that level.

We have assembled a team of experienced managers who possess the skills your organization deserves to be successful in aviation and manufacturing. Their practical experience and training is only complimented by their ability to attain positive results which enables them to represent you in a manner consistent with the trust, integrity, service and quality you deserve.

It is said that a laborer works with their hands, a technician with their mind, but a true professional works with their hands, their mind and their heart.

We embrace challenge by providing a comprehensive range of professional consulting services in program management, project management, governmental contracting, discrete research & development, aircraft certification, engineering & manufacturing on fixed and rotary wing aircraft.

Delivery Acceptance

During the interior completion process phase we will monitor the technical aspects of the aircraft including production drawings, airframe, powerplant, system build, quality, serialized component listing, certification documentation, manufacture service bulletin incorporation and product improvements. During final acceptance, a final review of all documents including the AFM, component handbooks, warranty documentation, cabin amenity operational instructions and passenger briefing cards will be conducted. Final review and basic compliance of required placards, systems isolation circuit breaker layouts, switch panels, etc. will be reviewed. Kestrel Group will also conduct a detailed of inspection and inventory of loose and spare equipment. A final report outlining any open items at delivery will be produced, providing a positive means of tracking any remaining issues.

Kestrel Group is ready to conduct a comprehensive pre-buy evaluation as your representative be it during the initial selection phases or prior to your contractual acceptance of a new or pre-owned aircraft.

Our pre-buy evaluation can be custom designed to your specific needs and would typically includesa complete review of the interior and exterior quality standards, specifications, manufacturer service bulletins, airworthiness directives and related method of compliance. In addition a review of the disposition of discrepancies to include life limited components, systems & equipment installations, ground and flight test results. A detailed report will be produced that can be used as a basis for final contract negotiation and future warranty claims.
Aircraft Inspection/Evaluation (Green)

Kestrel Group typically performs a comprehensive documentation review and general condition inspection on behalf of you the customer. This preliminary phase of evaluation is critical and necessary to detect discrepancies that may involve serial number listings, major part changes, modification status, and ground test or flight test data.

Technical acceptance of a green aircraft in most cases includes a review of functional test results, identification of deviations between the aircraft as-built with respect to as-was designed, configurations, specifications and documentation control. This final phase would help in the identification of any undocumented damage or related problems that could potentially contribute to future concerns. Depending on these initial findings the customer may be advised to incorporate a more detailed inspection on the airframe, powerplant, systems, components and accessories to identify the actual or physical condition of the product and related discrepancies.
