Maintenance

2. P C policy Policy & Objectives reventative orrective
The RAF’s maintenance policy
is based on a finely judged balance,
of preventative and corrective maintenance. P C
reventative
orrective
policy

3. Policy & Objectives ‘maintenance’ and ‘operational’.
A policy aimed too much at
preventing breakdowns (over maintenance)
would keep the aircraft in the hangar
most of the time.
So the objectives of the RAF’s
maintenance organisation
are in 2 main categories:
‘maintenance’ and ‘operational’.

4. Policy & Objectives Operational Objectives:
To generate the aircraft & equipment
to counter surprise attack.
To support intensive flying over a sustained
period in NBC or other hostile environments.
To generate aircraft and equipment required
for NATO & national commitments.
To satisfy such contingency plans
as may be ordered by a higher authority.
The efficient provision of serviceable aircraft
and equipment needed for peace time tasks.

5. Policy & Objectives Maintenance Objectives:
Minimise costs (manpower & resources)
Minimise faults that would be hazardous
to an aircraft
or affect it’s operational capabilities,
or would require expensive repair.
Find ever-better ways of improving reliability
and maintainability.

6. Types of Maintenance Let’s examine types of maintenance
utilised by the RAF:
The aim of Preventive Maintenance
is to reduce the probability of failures,
and ensure that performance of aircraft
and equipment is maintained.
It attempts to stop faults occurring.

7. Preventative Maintenance
Preventive Maintenance
covers four main headings –
Servicing
Scheduled Maintenance
Condition-based Maintenance
Out-of-Phase Maintenance
Let’s look at each one of them

8. Preventative Maintenance
Preventive Maintenance
covers four main headings –
Servicing
(or ‘flight servicing’ when applied to aircraft)
is the maintenance needed
after a period of use,
e.g. a flight,
plus preparation for the next period of use.

9. Preventative Maintenance
Preventive Maintenance
covers four main headings –
Scheduled Maintenance
Is regular maintenance to –
Keep the aircraft in a sound overall condition.
Minimise random faults.
Minimise the amount of routine day-to-day
attention needed.

10. Preventative Maintenance
Preventive Maintenance
covers four main headings –
Condition-based Maintenance
Some aircraft parts are continuously monitored
using non-destructive testing (NDT)
e.g. X-rays or
Spectrum Oil Analyzed Particles techniques
(SOAP)
until a condition that needs attention is revealed.

11. Preventative Maintenance
Preventive Maintenance
covers four main headings –
Out-of-Phase Maintenance
Is scheduled or condition-based maintenance
that does not fit the overall
maintenance cycle.

12. Types of Maintenance Corrective Maintenance Contingency Maintenance
As well as Preventive Maintenance
there are three other area of maintenance
we must look at –
Corrective Maintenance
Contingency Maintenance
Modifications

13. Types of Maintenance Corrective Maintenance
As well as Preventive Maintenance
there are three other area of maintenance
we must look at –
Corrective Maintenance
is carried out as and when a fault occurs.
It is not scheduled or planned for,
as the faults can occur at random.

14. Types of Maintenance Contingency Maintenance
As well as Preventive Maintenance
there are three other area of maintenance
we must look at –
Contingency Maintenance
In operational theatres it may be necessary
to relax maintenance standards,
suspending scheduled and
condition-based maintenance
in favour of relying on corrective maintenance
which varies between aircraft.

15. Types of Maintenance Modifications As well as Preventive Maintenance
there are three other area of maintenance
we must look at –
Modifications
are made to remedy any design faults
that come to light,
or to incorporate new technology
designed to
improve performance or safety.

16. Maintenance Records Aircraft Maintenance Data Log:
Every aircraft has an
Aircraft Maintenance Data Log:
An MOD Form 700
The F700 is actually a series of forms;
MOD Form 701 fuel and oil types, tyre pressures.
MOD Form 703 onboard software log.
MOD Form 705 flight servicing & fuel certificate.
MOD Form 725 flying log & fatigue data sheet.
MOD Form 725A air-to-air in flight refuelling.

17. Maintenance Records The F700 details are also recorded on the
Maintenance Data System (MDS).
concentrating on 6 main aspect of data –
Faults – Defects – Modifications
Manpower Utilisations
Task Achievement
Technical Costs & Logistics
These are all available to RAF Stations, Groups
and Commands via the MOD Intranet or disk.
This enables performance monitoring
and life span predictions for aircraft.

18. Check Understanding The RAF’s maintenance policy is based on
a finely judged balance of measures,
they are known as:
Preventative and Operational
Operational and Corrective
Corrective and Permanent
Preventative and Corrective

19. Check Understanding Keep the aircraft in the hangar most of the time.
A policy of over-maintenance would:
Keep the aircraft in the hangar
most of the time.
Ensure that aircraft were
never in the hangar.
Ensure that the aircraft were
always serviceable.
Generate the aircraft to
counter a surprise attack.

20. Check Understanding What is maintenance aimed to reduce the
probability of failures, restore levels of reliability,
and ensure that time and use do not affect
aircraft performance called?
Phased Maintenance
Corrective Maintenance
Preventative Maintenance
Scheduled Maintenance

21. Check Understanding Operational Maintenance Preventative Maintenance
Servicing, scheduled maintenance,
condition-based maintenance and
out-of-phase maintenance are all types of:
Operational Maintenance
Preventative Maintenance
Corrective Maintenance
Contingency Maintenance

22. Check Understanding Scheduled Maintenance Conditioned Maintenance
Maintenance performed after aircraft use,
and in preparation for the next flight,
is called what?
Scheduled Maintenance
Conditioned Maintenance
Flight Servicing
Out-of Phase Maintenance

23. Check Understanding Keeping an aircraft in sound overall condition,
minimising random faults and the amount of
routine day-to-day attention needed
are all aims of:
Modification
Contingency Maintenance
Condition-based Maintenance
Scheduled Maintenance

24. Check Understanding Out-of-Phase Maintenance
The use of NDT and SOAP
are elements of what?
Out-of-Phase Maintenance
Condition-based Maintenance
Corrective Maintenance
Contingency Maintenance

25. Check Understanding Modifications Contingency Maintenance
Scheduled or condition-based maintenance
which is needed at intervals that do not fit
the maintenance cycle are called what?
Modifications
Contingency Maintenance
Out-of Phase Maintenance
Condition-based Maintenance

26. Aircraft Maintenance Data Form
Check Understanding
What is the
Aircraft Maintenance Data Form
called?
MOD Form 700
MOD Form 7000
MOD Form 750
MOD Form 7500
