Has mature and large fleet
Has 737-700/800 and 900ERs
High aircraft utilization
Seasonal variation in utilization
( ie. Hadj season)
Flexible manpower available
Has central maintenance base

THY Maintenance Check Optimization
 A checks, which contains all of the tasks that have 1000 FH and
above intervals, will be accomplished in 2 shifts (0.66 days) at
the main base (IST) and will have an average of 105 manhours.
 L checks consist of less complicated tasks that have intervals
between 300 FH and 1000 FH. Moreover, they will be
accomplished in 1 shift (0.33 days) at 5 different out-stations
with an average of 45 manhour workload.
 There is going to be 2,85 A and 12 L checks per A/C annually.
The total amount for the entire 64 A/C fleet will be 182 A checks
and 768 L checks, which corresponds to a total ground time of
328 days.
 Total gain in ground time for the B737NG fleet will be 303 days.

For Turkish Airlines, as the ground time for planned maintenance
will be reduced by a total of 303 days, they will have 303 extra days
for the entire 737-NG fleet to operate, which will net them a total of
almost 9 million $ a year.
For Turkish Technic, lesser ground time of THY fleet will make
maintenance slots available for third party companies, resulting in
extra revenue. Moreover, since the maintenance deal with THY was
done in PbtH, 303 days will earn Turkish Technic 100.000 $ a year.

THY Maintenance Check Optimization
150 FH “A Checks” are converted into 300 FH / 30 Days “L Checks”
whereas 600 FH, Big A Checks are into 1000 FH A Checks.
New A checks are accomplished by a new A-Check maintenance
organization under Turkish Technic, which is specialized in A
Checks, making it possible to complete a 1000 FH maintenance at
the same amount of time with a 600 FH one.
Ground times caused by scheduled maintenance will be reduced by
303 days for the entire THY 737-NG fleet, from which THY will earn
around 9 million $ whereas Turkish Tehcnic will also receive
100.000 $ through PbtH agreement.

 THY Tecnich Job cards are prepared to base on the original manufacturer’s
document by Maintenance Engineering Dept. Most of the job cards consist of
the access panel lists which will be used for to access some maintenance areas.
 In previous Situation; job cards are distributed to the technicians who would be
work on the aircraft by supervisor. Supervisors also tried to grouping them for
preventing to duplication of the opening and closing the panels. But it was not
work all the time because of 3-shift working system.

 Access panel removal and
installation reference task
cards are created for every
possibility of working zone
and also cabin interior
(galleys, lavatories, seat
tracks, ceiling panels etc.) on
the aircraft. These task cards
includes detail information to
removing and installing the
panels with detailed figures.
 And also panel index lists
issued for all zone to use in
maintenance action

 Every maintenance package has
got its individual panel index
lists. One for removing the
panels which should be
removes in this maintenance
action, and one for installing
panels which was removed in
maintenance. All panels are
removed before maintenance,
after all job cards and EO’s are
applied, all panels are closed
with the installation task cards.
 Access Panel M/H values are
removed from the task card’s
itself and added to panel index
for helping to planning also

Within the context of the continuous improvement of business development
carried out by the unit according to the needs of the units, to include all the
processes are carried out maintenance or overhaul.
Studies of A and C check shortening the duration of B737NG TAT;
1. New material and toll kits
2. Keep ready to use be used materials, tools and kits before the maintenance
3. People organized for erranding the material and tool to the technichian who
is still work on the aircraft in maintenance action.
4. Put the board with PC for easy access to maintenance docments (AMM, IPC,
CMM etc.) for every aircraft which is in maintenance action.
with above type actions, all working distances are shorthend for technician in
maintenance action then gained up to %40 time for TAT.
