WARNING
It is critical for the recovery helicopter flight crew to
report any unusual occurrences. For example, vertical
bounce, severe jerking of the damaged helicopter,
hard landing of the damaged helicopter following
recovery, UMARK component failure, or exceeding the
flight parameters. Report any unusual occurrences to
the unit responsible for the damaged helicopter.
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
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.
