After finishing through with the first year of
university, I was looking to find a summer placement back home in Pakistan.
Fortunately enough, I managed to secure a placement at Pakistan International
Airlines (PIA), Pakistan’s national flag carrier. This was a two month long
summer placement, from June till September. In the scorching summer
temperatures of around 40°C,
I started off my placement in the month of Ramadhan, a period of fasting from
dawn till dusk for Muslims. As imagined, the field work pertaining to the
placement really took the energy out of me during such high temperatures while
observing fasts.
The placement involved students being divided
into groups and being rotated around Base Maintenance, Line Maintenance and the
Engine Overhaul Shop. Seeing an aircraft with such highly precisioned engines
in front of your eyes was a sight I cannot describe into words. While working
at Base Maintenance, I was able to witness aircraft undergoing
checks based on the class of check the aircraft was due to undergo depending on
cycles and flight hours, namely the A, B, C, and D check. I also had a chance
to work in Line Maintenance, witnessing how aircraft are serviced on ground
before being sent off for flights. I have also worked extensively in the engine
shop, where engines used to come in for shop visits and go through the rigorous
process of being checked for snags before being sent off for service. After
cleaning and NDT inspection, any components found that required machining or
repair were sent off to the Machine shop where processes such as lathing,
boring, and drilling were done to make the component serviceable again. This
allowed me to witness Computerised Numerical Control (CNC) machines, including
the CNC Vertical Turret Lathe and the CNC horizontal boring machine. After
repair and modification, parts were sent to the general assembly area to be put
together. The engines were then sent to the test bench for final clearance
after verifying errors.
After having rotated around the
aforementioned areas, we were also sought to assist ground engineers in helping
repair any sort of snags that would come up. This gave us a hands-on approach
and helped put our knowledge to use. PIA also services aircraft and engines for
the other privately owned airlines in Pakistan, and therefore I also had a
chance to go and help out engineers working on an Air Indus aircraft. Since the
shops were located very close to the runway of the Karachi Airport, seeing
aircraft taking off and landing in front of a matter of a few meters distance
was simply breathtaking!
This placement provided me with
the chance to
put thermodynamics and fluid mechanics theories to practicality while learning
about different aspects of aerodynamics, fluid hydraulics, and pneumatics. Apart
from the obvious networking and teamwork skills, this unique experience
provided me with an opportunity to learn extensively about the theory of flight
and a basic gas turbine engine. This experience allowed my confidence to
flourish while working in a team of interns in a very competitive environment.
