d. Damage to the tail boom to such an extent that it is not suitable as a lifting point.
e. Bending or buckling of the airframe so as to create aerodynamic instabilities that could result in additional
damage during the recovery flight.
f.
Engines severely damaged or separated from the airframe.
UMARK is designed to allow three ground personnel to rig a disabled or damaged helicopter for aerial recovery in
less than 15 minutes. The disabled or damaged helicopters are not required to be stripped of components, de-
fueled, disarmed, or have any additional maintenance actions performed on them prior to aerial recovery.
UMARK can be installed under all environmental conditions, day or night (using artificial illumination or night vision
equipment), by personnel wearing combat mission oriented protective posture (MOPP-4), or cold weather
protective gear. It can be transported internally by the UH-1 helicopter or in a larger utility/cargo helicopter and
transported on the ground by unit organic vehicles.
Recovery helicopter models, disabled helicopter models, maximum allowable recovery weights, and eligible
recovery helicopter hook-up configurations are listed in Table 1. Stated weights will vary with mission distance,
weather conditions, and helicopter configuration.
