Damage to hearing occurs when you expose your
ears to high sound intensities for excessive periods. The
higher the sound intensity, the shorter the period of
exposure that will produce damage. As stated in an
earlier chapter, exposures above an 84-dB(A) sound
intensity, without hearing protection, can cause hearing
damage.
The wearing of approved earplugs or sound
attenuators will protect you from hearing loss. In
extremely high noise level areas, such as the flight line,
even double protection may not be enough protection.
In such cases, time limits are set for allowable exposures
to noise. Wearing hearing protection can raise the limits
of time exposure. All personnel working within danger
areas should be familiar with calculated decibel levels
(as specified in the applicable maintenance instruction
manual) and should wear the required protective
equipment.
Movable Surface Hazards
Movable surfaces such as flight control surfaces,
speed brakes, power-operated canopies, and landing
gear doors are a major hazard to flight line personnel.
These units are normally operated during ground
operations and maintenance. Therefore, you should
ensure that all personnel and equipment are clear of the
area before operating any movable surface.
SUMMARY
In this chapter, we addressed the scope and goal of
the Naval Aviation Safety Program. We covered the
concepts and individual responsibilities associated with
the safety program. We discussed the command aviation
safety program functions and its elements. We
examined hazard reports, naval aircraft mishap reports,
and mishap investigation reports. We considered the
endorsements required on both hazard reports and
mishap investigation reports. We examined general
shipboard aircraft safety. Finally, we discussed the
importance of monitoring mishap corrective actions.
We did not intend for this chapter to make you an
expert in naval aviation safety. The chapter was
developed to provide you with a basic introduction to
aviation safety as well as the references you should
consult for additional information.
