Maintenance final exam questions with
verified solutions graded A+ passed
Describe a transit check. When is it done? What is accomplished? Where is the
work done? - correct answer ✔✔A maintenance check is performed prior to each
flight. Service engine oil as required Check RAM air inlet/exhaust doors and cabin
pressure outflow valve for condition and obstructions Check positive pressure
relief valves, basically a walk around with some fluid checks. Performed on the
ramp.
Describe A and C checks. When are they done? What is accomplished? Where is
the work done? How involved is the work done for each check? How long is the
aircraft down for maintenance? - correct answer ✔✔A checks are done every
usually around 400-700 FH, things such as filters might be changed, liquids will be
refilled, emergency items will be checked and other quick tasks. An A check will
take several hours and is somewhat detailed although compared to other letter
checks it is not very detailed. Also, A checks are usually done in a hanger as
different tools are needed. C checks are done every 1.5 to 2 years or if the aircraft
has around 3000-5000 FH. They take about 3-7 days to complete and is done C
checks include everything in a A check but also include things such as routine,
variable-routine, and nonroutine checks. They are very detailed and take a while if
you don't have a lot of staff to work on them.
Routine Tasks: - correct answer ✔✔Routine tasks are tasks that are performed at a
specific interval. Time to perform will vary and can be detailed or non-detailed.
, Variable-routine Tasks - correct answer ✔✔tasks will include things such as SBs
and ADs, floot campaigns, deferred items, and other one-time actions. When
planning these, the time to finish is usually a fixed number of days or a date.
Non-routine Tasks - correct answer ✔✔After another task has been completed
you may have to do a non-routine task. Such as if you are to inspect if there is a
fuel line leak, and you discover that there is indeed a leak, you will have to
perform non-routine maintenance. The time required to finish a task can be
estimated.
What are the three primary functions of PP&C? - correct answer ✔✔The three
primary functions of PP&C are to maximize maintenance and Engineering efforts,
plan and organize future work, and Adjust plans/schedules to meet changing
requirements.
Why is forecasting maintenance so important? - correct answer ✔✔Forecasting
maintenance is so important as it helps minimize the future workload of the
maintenance department. It also allows maintenance to start faster and end
quicker. Spreading out the workload allows for less staff to be working on the
same project, making it much more efficient.
Identify some reasons why maintenance may be deferred. - correct answer
✔✔Maintenance may be deferred if there is a lack of parts, labor, and or time.
Maintenance can be scheduled but that does not mean that it cannot be deferred
due to the reasons listed above.
When does PP&C begin to plan the time allotted for a maintenance check (A or
C)? - correct answer ✔✔The PP&C allots time based on past knowledge of work
done Aswell as assumptions based on parts, manpower, facilities and supplies.
