How do you lift a submerged 100-ton Airbus A320 aircraft
that has taken on an additional 350 tons of water? Very
carefully!
By now we’ve all heard the story of “Miracle on the
Hudson” where the Airbus 320 crashed into the icy Hudson
River a few weeks ago after reportedly striking a flock of
birds. The cool-headed pilot managed to safely land the
plane and all 155 passengers and crew survived.
As this is one of the first large jets to safely land in water,
safety and aviation experts needed to recover the craft from
the icy waters so that they can inspect the airplane and gather
much-needed information. Careful planning was necessary in
order to safely remove the plane.
As our maintenance crews and anyone who’s been involved
with cranes on construction and maintenance projects know,
planning for this type of lift requires a Critical Lift Plan. By
definition, a critical lift is a non-routine crane lift requiring
detail planning and additional or unusual safety precautions.
Thanks to the diligent efforts and expert planning of those
involved in the lift, the plane was safely lifted, loaded on
to a barge and taken to a marine yard where the wings are
being removed and tail section cut down before it is moved
to another location where experts will conduct a thorough
investigation.
For more information on crane safety and critical lifts,
see Section 16 of EM 385-1-1 (Corps of Engineers Safety
and Health Requirements Manual) http://www.usace.army.mil/
CESO/Documents/Section%2016-2008.pdf , Section 16.H.
specifically discusses critical lifts.

(counter clockwise) The plane
involved in the “Miracle on the
Hudson”, US Airways flight 1549
is lifted out of the Hudson River
after being submerged. Its skilled
pilot landed the plane and its 155
passengers and crew in the river,
following loss of both engines. The
plane is pictured after completed
recovery from the river and placed on
a barge for transport. Pictured is the
plane partially submerged during the
lifting portion of the recovery. Weeks
Marine, a major New Jersey-based
dredging firm, dispatched two marine
cranes as effort began to secure and
retrieve the damaged aircraft partially
submerged in the Hudson. Divers
used a tiny model of the downed
aircraft to plan rigging and hoisting
strategy. Familiarity with the plane
superstructure allowed the project
team to retrieve the craft in one piece,
enabling it to be studied by safety
investigators.-- Courtesy photos.
