Direct Operational Authority.
Real-World Crisis Management.
I bring three decades of hands-on aviation leadership to your legal team. Unlike academic experts, I have exercised Tier-One Operational Control for multi-base EMS programs, making the final "go/no-go" decisions that are often at the center of litigation.
Crisis Management
Directed the operational response and NTSB interface for a Bell 222U fatal accident caused by mechanical failure. I understand the audit trail of a catastrophe.
In-Flight Emergencies
Personally survived a tail rotor drive shaft failure with a successful emergency landing. I offer unique insight into pilot decision-making under extreme duress.
Regulatory Influence
Active contributor to the FAA/AAMS Part 135 Rewrite Taskforce and the development of 14 CFR ยง135.611. I don't just read regulations; I helped shape them.
