Overview
• Introduction
• What is MIL-HDBK-516C, Airworthiness
Certification Criteria
• Processes
• What Has Changed
• New Forms
– T-2 Modification Airworthiness Impact
Determination and Preliminary Hazard Analysis
– T-2 Modification Airworthiness Compliance
– Military Flight Release
• This should give a high level view to set up a
risk and airworthiness assessment exercise

Introduction
• 2010, the Air Force mandated Independent
Airworthiness (IAW) assessment program.
– AFI 62-601, USAF Airworthiness
– Based on MIL-HDBK-516C
• IAW requires all aircraft go through a rigorous
independent assessment prior to the aircraft
released for first flight.
• IAW program requires aircraft modifications go
through a similar assessment.
– T-2 Mod process now includes a more robust
design and review process using MIL-HDBK-
516C.

MIL-HDBK-516C 12 December 2014
• Required per AFI 62-601
• Based on MIL-HDBK-516C
– Arranged by aircraft subsystems
– Used to Determine Airworthiness Criteria
• Tailored Airworthiness Certification Criteria
• Modification Airworthiness Certification Criteria
– References DoD Specifications and Standards
– References NATO and FAA Documents
– References other Non-Government Publications
• Represents System Engineering Approach

How to Integrate Processes
• Generated many questions
– How do we integrate?
– Where do we integrate?
– Will processes change?
– Will responsibilities change or grow?
– Will this add to schedule?

Integrating Processes
Old Terminology
• Major
– High Degree of Technical
Uncertainty
– Affects one or more
areas
• Minor
– All other modifications
New Terminology
• Reportable
– Impact to AW
– High Risk/TAA Approval
• Nonreportable
– Impact to AW
– Lower Risk/Local Approval
• No Impact to
Airworthiness
– Low Risk/Compliant with
MIL-HDBK-516C Standards

Experts (SME)
– AFLCMC
– AFTC
– SMEs from 412 TW and 96 TW
• Engineering
• Mod/Configuration Management
• SEEK EAGLE
