WARNING
Exceeding the flight parameters may severely damage
the main rotor assembly of the damaged helicopter,
requiring component replacement. Report the amount
and duration of any flight parameter exceeded to the
unit responsible for the damaged helicopter.
The height above ground level may be difficult to
determine during low-level UMARK operations due to the
length of the sling system. Flight crews should exercise
extreme caution during recovery operations to ensure the
damaged helicopter remains clear of ground obstacles.
4. COMPONENTS REQUIRED
NOTE
Recovery of a UH-60 with a damaged main rotor, main
transmission, or main transmission mount requires the use of
three standard heavy weight black/white slings and one heavy
weight black/white sling with bridle loops. The UMARK kit
contains on two standard heavy weight black/white slings; the
other sling must be obtained from another kit.
Components of UMARK utilized during the one-hook, long-line recovery are listed in Table 2. Common equipment
used by the ground rigging crew, such as shockproof gloves, goggles, radios, etc., are not included in UMARK.
No additional tools are required for UMARK assembly or rigging of the helicopters.
