of accident from improper
operational procedures. Mechanical failure cannot
be completely neutralized, but trained personnel can
make such a failure a rarity.
Recovering aircraft involves various inherent
dangers, due to the complex coordination of
personnel and machinery. Personnel engaged in the
operation of the arresting gear equipment must be
thoroughly trained and indoctrinated in the
Disregard for the fundamentals of
caution and safety creates hazards far in excess of
the previously mentioned inherent danger factors.
COMMAND, COMMUNICATIONS, AND
Accuracy of command, attention to command,
and care of communications systems must be
understood by all operating personnel. The system
may be phones, synchro signals, or lights and must
be wholly operative at time of use. Accuracy in
making proper settings of gears, indicator systems,
tension, and pressure tests must be emphatically
impressed on all personnel. The following general
safety observations are arranged according to
location, and copies should be supplied to all
TOPSIDE AND DECKEDGE AREAS
During arrestment, all topside and deckedge
personnel should be aware of all movement on and
about the deck, with strict attention paid to the
landing aircraft. Deckedge control operators should
duck below deck level during pendant arrestment in
the event of pendant breakage or failure that would
cause cable whip or the aircraft to go over the deck
Hook runners should approach aircraft from the
front and side.
This will place them away from
danger of jet blast or broken cable backlash.
Catwalk personnel should be held to a minimum
so they can exit quickly should they be placed in
Rapid fuel consumption by jet aircraft requires
highly trained, responsible crews for rigging the
barricades. Regular drills in rigging should be held
to reduce rigging time to a minimum.
Air in the cylinder or a valve that does not seat
properly are the major causes of walkback. This is
an extremely dangerous occurrence, as the pilots
have no control over the aircraft in addition to
being unable to see where they are going, thus the
aircraft may go overboard, endanger deckedge
personnel, or cause injury to personnel on deck not
paying attention to what is happening around them.
The retracting cycle of the deck pendant is
normally executed at full speed. The operator, prior
to pulling the retracting lever, must ascertain that no
personnel or equipment arc in a position to be
struck during retraction. If for any reason a sudden
interruption of the retracting cycle occurs, the same
precaution must be taken prior to the resumption of
the retraction cycle.
Broken or deformed wire supports should be
replaced as soon as practical.
Personnel should stay clear of areas where
stanchions are being raised or lowered, and
particularly when barricades are being raised or
lowered. When stanchion repair is to be effected,
the stanchions should be lashed upright to provide
Terminals, Fittings, and Cables
Frequent inspection of all cables, terminals, and
fittings should be maintained. Any indication (no
matter how slight) of failure should be corrected
immediately. Particular attention should be given to
terminals jamming sheaves. Any condition where
this is evident is extremely critical.
involved should not be operated until correction of
the condition is made.
