HISTORY of s/n 76-22599:
This is one of the few production TAH-1P Cobras procured by the U.S. Army to serve as Cobra flight transition trainers. The aircraft is unique in that it has a flight control over-ride system in the front seat flight controls for an Instructor Pilot. The TAH-1P Cobra is identical to a fully mission capable Cobra attack helicopter except functional weapon systems were not installed in the production TAH-1P.
The aircraft is painted in its U.S. Army markings when it first went into U.S. Army operational service in 1978 with A Company, 229th Attack Helicopter Battalion, 101st Airborne Division at Fort Campbell, KY. The aircraft latter served with the 7th Combat Aviation Battalion, 7th Infantry Division at Fort Ord, CA. The aircraft last served as a Cobra transition trainer at the Army Aviation Center, Fort Rucker, AL.
The aircraft has performed extensively since 1999 on the U.S. air show circuit with the Sky Soldiers Demonstration Team of the Army Aviation Heritage Foundation (AAHF). >>>
