To keep aircraft in peak operating condition, aircraft and avionics
equipment mechanics and service technicians perform scheduled
maintenance, make repairs, and complete inspections required by the
Federal Aviation Administration (FAA).
Many aircraft mechanics, also called airframe, powerplant, and
avionics aviation maintenance technicians, specialize in preventive
maintenance. They inspect engines, landing gear, instruments,
pressurized sections, accessories—brakes, valves, pumps, and
air-conditioning systems, for example—and other parts of the aircraft,
and do the necessary maintenance and replacement of parts. Inspections
take place following a schedule based on the number of hours the
aircraft has flown, calendar days since the last inspection, cycles of
operation, or a combination of these factors. Large, sophisticated
planes are equipped with aircraft monitoring systems, consisting of
electronic boxes and consoles that monitor the aircraft’s basic
operations and provide valuable diagnostic information to the mechanic.
To examine an engine, aircraft mechanics work through specially designed
openings while standing on ladders or scaffolds, or use hoists or lifts
to remove the entire engine from the craft. After taking an engine
apart, mechanics use precision instruments to measure parts for wear and
use x-ray and magnetic inspection equipment to check for invisible
cracks. Worn or defective parts are repaired or replaced. Mechanics may
also repair sheet metal or composite surfaces, measure the tension of
control cables, and check for corrosion, distortion, and cracks in the
fuselage, wings, and tail. After completing all repairs, they must test
the equipment to ensure that it works properly.
Mechanics specializing in repairwork rely on the pilot’s
description of a problem to find and fix faulty equipment. For example,
during a preflight check, a pilot may discover that the aircraft’s
fuel gauge does not work. To solve the problem, mechanics may
troubleshoot the electrical system, using electrical test equipment to
make sure that no wires are broken or shorted out, and replace any
defective electrical or electronic components. Mechanics work as fast as
safety permits so that the aircraft can be put back into service
quickly.
Some mechanics work on one or many different types of aircraft, such
as jets, propeller-driven airplanes, and helicopters. Others specialize
in one section of a particular type of aircraft, such as the engine,
hydraulics, or electrical system. Powerplant mechanics are
authorized to work on engines and do limited work on propellers. Airframe
mechanics are authorized to work on any part of the aircraft
except the instruments, powerplants, and propellers. Combination
airframe-and-powerplant mechanics—called A & P
mechanics—work on all parts of the plane, except instruments. The
majority of mechanics working on civilian aircraft today are A & P
mechanics. In small, independent repair shops, mechanics usually inspect
and repair many different types of aircraft.
Avionics systems are now an integral part of aircraft design and
have vastly increased aircraft capability. Avionics technicians
repair and maintain components used for aircraft navigation and radio
communications, weather radar systems, and other instruments and
computers that control flight, engine, and other primary functions.
These duties may require additional licenses, such as a radiotelephone
license issued by the U.S. Federal Communications Commission (FCC).
Because of technological advances, an increasing amount of time is spent
repairing electronic systems, such as computerized controls. Technicians
also may be required to analyze and develop solutions to complex
electronic problems.
Mechanics usually work in hangars or in other indoor areas, although
they can work outdoors—sometimes in unpleasant weather—when hangars
are full or when repairs must be made quickly. Mechanics often work
under time pressure to maintain flight schedules or, in general
aviation, to keep from inconveniencing customers. At the same time,
mechanics have a tremendous responsibility to maintain safety standards,
and this can cause the job to be stressful.
Frequently, mechanics must lift or pull objects weighing as much as
70 pounds. They often stand, lie, or kneel in awkward positions and
occasionally must work in precarious positions on scaffolds or ladders.
Noise and vibration are common when engines are being tested, so ear
protection is necessary. Aircraft mechanics usually work 40 hours a week
on 8-hour shifts around the clock. Overtime work is frequent.
Aircraft and avionics equipment mechanics and service technicians
held about 154,000 jobs in 2002; about 1 in 6 of these workers was an
avionics technician. Nearly 40 percent of aircraft and avionics
equipment mechanics and technicians worked for air transportation
companies and close to 20 percent worked for private maintenance and
repair facilities. About 20 percent worked for the Federal Government,
and about 13 percent worked for aerospace products and parts
manufacturing firms. Most of the rest worked for companies that operate
their own planes to transport executives and cargo. Few mechanics and
technicians were self-employed.
Most airline mechanics and service technicians work at major
airports near large cities. Civilian mechanics employed by the U.S.
Armed Forces work at military installations. Large proportions of
mechanics who work for aerospace manufacturing firms are located in
California or in Washington State. Others work for the FAA, many at the
facilities in Oklahoma City, Atlantic City, Wichita, or Washington, DC.
Mechanics for independent repair shops work at airports in every part of
the country.
The majority of mechanics who work on civilian aircraft are
certificated by the FAA as “airframe mechanic,” “powerplant
mechanic,” or “avionics repair specialist.” Mechanics who also
have an inspector’s authorization can certify work completed by other
mechanics and perform required inspections. Uncertificated mechanics are
supervised by those with certificates.
The FAA requires at least 18 months of work experience for an
airframe, powerplant, or avionics repairer’s certificate. For a
combined A & P certificate, at least 30 months of experience working
with both engines and airframes is required. Completion of a program at
an FAA-certified mechanic school can substitute for the work experience
requirement. Applicants for all certificates also must pass written and
oral tests and demonstrate that they can do the work authorized by the
certificate. To obtain an inspector’s authorization, a mechanic must
have held an A & P certificate for at least 3 years. Most airlines
require that mechanics have a high school diploma and an A & P
certificate.
Although a few people become mechanics through on-the-job training,
most learn their job in 1 of about 200 trade schools certified by the
FAA. About one-third of these schools award 2- and 4-year degrees in
avionics, aviation technology, or aviation maintenance management.
FAA standards established by law require that certified mechanic
schools offer students a minimum of 1,900 actual class hours. Coursework
in these trade schools normally lasts from 24 to 30 months and provides
training with the tools and equipment used on the job. Aircraft trade
schools are placing more emphasis on technologies such as turbine
engines, composite materials—including graphite, fiberglass, and
boron—and aviation electronics, which are increasingly being used in
the construction of new aircraft. Additionally, employers prefer
mechanics who can perform a variety of tasks.
Some aircraft mechanics in the Armed Forces acquire enough general
experience to satisfy the work experience requirements for the FAA
certificate. With additional study, they may pass the certifying exam.
In general, however, jobs in the military services are too specialized
to provide the broad experience required by the FAA. Most Armed Forces
mechanics have to complete the entire training program at a trade
school, although a few receive some credit for the material they learned
in the service. In any case, military experience is a great advantage
when seeking employment; employers consider trade school graduates who
have this experience to be the most desirable applicants.
Courses in mathematics, physics, chemistry, electronics, computer
science, and mechanical drawing are helpful, because they demonstrate
many of the principles involved in the operation of aircraft, and
knowledge of these principles is often necessary to make repairs.
Courses that develop writing skills also are important because mechanics
are often required to submit reports.
FAA regulations require current experience to keep the A & P
certificate valid. Applicants must have at least 1,000 hours of work
experience in the previous 24 months or take a refresher course. As new
and more complex aircraft are designed, more employers are requiring
mechanics to take ongoing training to update their skills. Recent
technological advances in aircraft maintenance necessitate a strong
background in electronics—both for acquiring and retaining jobs in
this field. FAA certification standards also make ongoing training
mandatory. Every 24 months, mechanics are required to take at least 16
hours of training to keep their certificate. Many mechanics take courses
offered by manufacturers or employers, usually through outside
contractors.
Aircraft mechanics must do careful and thorough work that requires a
high degree of mechanical aptitude. Employers seek applicants who are
self-motivated, hard-working, enthusiastic, and able to diagnose and
solve complex mechanical problems. Agility is important for the reaching
and climbing necessary to do the job. Because they may work on the tops
of wings and fuselages on large jet planes, aircraft mechanics must not
be afraid of heights.
As aircraft mechanics gain experience, they may advance to lead
mechanic (or crew chief), inspector, lead inspector, or shop supervisor
positions. Opportunities are best for those who have an aircraft
inspector’s authorization. In the airlines, where promotion often is
determined by examination, supervisors sometimes advance to executive
positions. Those with broad experience in maintenance and overhaul might
become inspectors with the FAA. With additional business and management
training, some open their own aircraft maintenance facilities. Mechanics
learn many different skills in their training that can be applied to
other jobs, and some transfer to other skilled repairer occupations or
electronics technician jobs.
Opportunities for aircraft and avionics equipment mechanics and
service technician jobs should be excellent for persons who have
completed aircraft mechanic training programs. Employment of aircraft
mechanics is expected to increase about as fast as the average for all
occupations through the year 2012, and large numbers of additional job
openings should arise from the need to replace experienced mechanics who
retire. Avionics technicians are projected to increase at a slower than
average rate. Despite the long-term forecast, these occupations are
currently in a period of little to no growth. Reduced passenger traffic
resulting from a weak economy and the events of September 11, 2001, have
forced airlines to cut back flights and take aircraft out of service. As
the economy improves and public reluctance to board aircraft decreases,
a growing population should increase passenger traffic and create the
need for more aircraft mechanics and service technicians over the next
decade. If the number of graduates from aircraft mechanic training
programs continues to fall short of employer needs, opportunities for
graduates of mechanic training programs should be excellent.
Most job openings for aircraft mechanics through the year 2012 will
stem from replacement needs. A large number of mechanics are expected to
retire over the next decade and create several thousand job openings per
year. In addition, others will leave to work in related fields, such as
automobile repair, as much of their skills are transferable to other
maintenance and repair occupations. Also contributing to favorable
future job opportunities for mechanics is the long-term trend towards
fewer students entering technical schools to learn skilled maintenance
and repair trades. Many of the students who have the ability and
aptitude to work on planes are choosing to go to college, work in
computer-related fields, or go into other repair and maintenance
occupations with better working conditions. If the trend continues, the
supply of trained aviation mechanics will not be able to keep up with
air transportation industry needs when growth resumes in the industry.
Job opportunities are likely to be the best at small commuter and
regional airlines, at FAA repair stations, and in general aviation.
Commuter and regional airlines are the fastest growing segment of the
air transportation industry, but wages in these companies tend to be
lower than those in the major airlines, so they attract fewer job
applicants. Also, some jobs will become available as experienced
mechanics leave for higher paying jobs with the major airlines or
transfer to another occupation. At the same time, general aviation
aircraft are becoming increasingly sophisticated, boosting the demand
for qualified mechanics. Mechanics will face more competition for jobs
with large airlines because the high wages and travel benefits that
these jobs offer generally attract more qualified applicants than there
are openings. In spite of this, job opportunities with the airlines are
expected to be better than they have been in the past. But, in general,
prospects will be best for applicants with experience. Mechanics who
keep abreast of technological advances in electronics, composite
materials, and other areas will be in greatest demand. The number of job
openings for aircraft mechanics in the Federal Government should decline
as the government increasingly contracts out service and repair
functions to private repair companies.
Median hourly earnings of aircraft mechanics and service technicians
were about $20.71 in 2002. The middle 50 percent earned between $16.94
and $25.23. The lowest 10 percent earned less than $13.16, and the
highest 10 percent earned more than $28.92. Median hourly earnings in
the industries employing the largest numbers of aircraft mechanics and
service technicians in 2002 were:
Air transportation, scheduled
$23.48
Federal Government
20.59
Air transportation, nonscheduled
19.84
Aerospace product and parts manufacturing
19.68
Support activities for air transportation
17.64
Median hourly earnings of avionics technicians were about $20.21 in
2002. The middle 50 percent earned between $17.44 and $23.91. The lowest
10 percent earned less than $14.01, and the highest 10 percent earned
more than $27.00.
Mechanics who work on jets for the major airlines generally earn
more than those working on other aircraft. Airline mechanics and their
immediate families receive reduced-fare transportation on their own and
most other airlines.
Almost 4 in 10 aircraft and avionics equipment mechanics and service
technicians are members of or covered by union agreements. The principal
unions are the International Association of Machinists and Aerospace
Workers and the Transport Workers Union of America. Some mechanics are
represented by the International Brotherhood of Teamsters.
