LINE AND FLIGHT DECK
The command should make sure it effectively
covers programs in general safety, such as hearing
conservation, flight deck/flight line safety, traffic safety,
home safety, and hazardous materials.
SHIPBOARD AIRCRAFT SAFETY
Flight decks are hazardous, and their danger to
personnel goes beyond the chance of crashes. Exhausts
on jet engines can propel personnel into other objects or
over the side of the ship. Propellers and rotor blades can
maim or kill. Aircraft carry ordnance and fuel that can
cause fires and explosions. Moving aircraft can hit
personnel. The ship pitches and rolls. For those reasons,
all personnel whose job requires them to work on the
flight deck must be constantly alert and aware of all
dangers to avoid injury or death.
Flight line safety precautions, discussed later, apply
to flight deck operations. The primary difference is the
limited space and tempo of operations experienced on
the flight deck. The flight deck is increasingly more
All personnel assigned flight quarters on or above
the hangar deck must wear appropriate jerseys and
helmets. Personnel on the flight deck during flight
quarters must wear the following equipment:
A cranial impact helmet or its equivalent
Flight deck shoes
An adequately secured whistle
A survival light
FOREIGN OBJECT DAMAGE
Engines can suck up loose objects from the deck or
area around the intake. That can cause costly foreign
object damage (FOD) or complete loss of the engine.
Personnel must inspect the deck and other areas for FOD
by conducting FOD walkdowns before beginning air
operations or when starting engines for maintenance.
Flight deck personnel must not put loose objects in shirt
pockets and must keep their shirt pockets buttoned while
they are in a flight operations area. FOD prevention is
one of the reasons we prohibit the dumping of trash and
garbage during launch and recovery operations.
You must observe several miscellaneous safety
precautions when working on the aircraft flight line and
the carrier flight deck. The following precautions are of
special importance to ensure your safety as well as the
safety of your co-workers.
Propellers and Rotors
The first general precaution you must observe when
working on the line around propeller-driven aircraft or
helicopter rotors is to BEWARE OF PROPELLERS.
When you see a propeller, let it be a constant reminder
to STAY CLEAR! In general, do not cross in front of
moving propellers, as whirling propellers are not easily
seen. A good habit is to always walk around propellers.
Keep the area around the aircraft clear of loose gear and
Maintenance of jet engines presents several major
hazards. The air intake duct of operating jet engines
represents an ever-present hazard. It is a hazard both to
personnel working near the inlet duct of the aircraft and
to the engine itself if the turn-up area around the front
of the aircraft is not kept clear of debris. Jet engines will
eat anything, and they have no respect for life or limb.
This hazard is, of course, greatest during maximum
power settings (high-power turn-up).
The air inlet duct may develop enough suction to
pull hats, eyeglasses, loose clothing, and rags from
pockets. Personnel should properly secure or remove all
loose articles before working around operating jet
engines. In some engines, the suction is strong enough
to pull a person up to or, in some cases, into the inlet and
pull the persons eyeballs out. Needless to say, person-
nel must take every precaution to keep clear of the
Protective screens are supplied as part of the
ground-handling equipment for most jet aircraft. These
screens should be installed before maintenance
turn-ups. The use of turn-up screens protects both per-
sonnel and engines. It does NOT eliminate the need for
caution; a person can receive serious injury as a result
of being pulled against the screen. Small items can be
pulled through the screen, resulting in thousands of
dollars of damage to the engine.
