AMTIL Signs MOU For Strategic Partnership with Finberg Firm PLLC

Inside the Wings: Keeping Boeing 717s Safe and Soaring

Writer: Mary BartonMary Barton

My name is Mary, and I am a Hawaiian Airlines Aircraft Maintenance Technician. I have worked in the aviation industry for 4 years, and I couldn’t not have imagined a better, more fulfilling career field. I am a base maintenance mechanic, so I mainly work the C-checks on the Boeing 717s.

Hawaiin Airlines 717

These planes fly back and forth between the Hawaiian islands, taking about 11 flights each day. Since they have so many flights every day, it causes a lot of stress on the aircraft structure due to the constant pressure changes. When the plane comes in for the heavy check, we are tasked with removing so many different components, which include flight controls (ailerons, spoilers, elevators and rudder), all the cabin seats and cargo bay floors, as well as many other equipment items. Everything is then thoroughly inspected for damage and corrosion, and it is all fixed or replaced and put back exactly the way it came. This whole process will take 1-2 months, depending on the condition that the aircraft comes to us in.


Since I am a petite woman, I have the advantage that I can fit in a few places that many

others cannot. One of these places is the fuel tanks, that are located inside both wings and under the floor in the center of the cabin. These metal tanks are multiple chambers that are

5 feet long, 2 feet wide and 2 feet tall and each one is divided by a then metal wall with two

lightning holes in that wall. The purpose of entering a fuel tank can be internal repairs of rivets or sealant patches, and fuel pipe removal and installation to gain access for inspection areas. When I am tank diving, I have a small entrance hole from the ground that I can hardly fit my shoulders through, and I often jump through each chamber through those lightning holes. It can be physically demanding due to the constricted space and rigidity inside. However it is also psychologically challenging to fight any feelings of claustrophobia and to remain calm if you ever feel like you become stuck inside.



However difficult this job may seem, I have found that it has all been fulfilling and worth every bit of effort I have put into this job. Since embarking into my journey of aviation maintenance, I have a much greater appreciation for connecting people with the rest of the world and helping them travel safely to wherever they need to go. Aviation is a magnificent industry that makes the world more accessible to everyone. I enjoy having the ability to see the passengers be able to board our planes and feel completely safe, comfortable, and relaxed on their flights as a direct result of my hard work and dedication.
