Aircraft mechanic in training

I’m Navin Rajcoomar. I worked in IT for 17 years and I’m now studying for my FAA Airframe & Powerplant license. This site has the practice quizzes I make for my classes and a page on people from aviation history I admire.

What I do

What I’m working on now, and what I bring with me from IT.

  1. 01

    Maintenance training

    A&P coursework and shop time in airframe, powerplant and avionics at AIM Orlando.

  2. 02

    Doing it by the book

    Follow the manual, torque to spec and write it down. The paperwork is part of the job.

  3. 03

    Troubleshooting

    Understand how the whole system works before swapping parts. That goes for a hydraulic system as much as a server.

  4. 04

    Study tools

    I make my own quizzes from the handbooks and class notes. It’s how I study, and other students are welcome to use them.

  5. 05

    Always learning

    From server racks to turbine engines, I read the source material and keep asking how things work. There’s always something new to pick up.

Heritage · Pioneers Kitty Hawk · Est. 1903

Standing on their shoulders

A few people from aviation and engineering history whose work I keep coming back to.

Wilbur and Orville Wright

Wright Brothers

Pioneers of Powered Flight · 1903

Two bicycle makers from Dayton, Ohio, who made the first controlled, powered airplane flight at Kitty Hawk in 1903. They tested carefully and kept detailed records, which is still how good maintenance gets done.

Frank Whittle

Frank Whittle

Inventor of the Jet Engine · 1930

An RAF officer who patented the turbojet in 1930. It took him about ten years to get official backing and an engine in the air. The turbine engines I study today go back to his work.

Nikola Tesla

Nikola Tesla

Inventor & Electrical Engineer · 1856–1943

Developed the alternating current system and the induction motor that most of the power grid still runs on. He died nearly broke in New York in 1943.

A few quotes I like

The scientists of today think deeply instead of clearly. One must be sane to think clearly, but one can think deeply and be quite insane. The present is theirs; the future, for which I really worked, is mine.

T
Nikola TeslaInventor & Electrical Engineer

It is possible to fly without motors, but not without knowledge and skill.

A nation's ability to fight a modern war is as good as its technological ability.

My expertise

Where I am with aviation, and what I did before it.

Aircraft systems — A&P

FAA Airframe & Powerplant

I’m working toward my FAA A&P certificate at the Aviation Institute of Maintenance in Orlando, with regular hands-on time in the shop.

School
AIM Orlando, Florida
Systems
Fuel, hydraulics, fire protection, instruments
Goal
MRO with a major carrier

Turbine & powerplant

The part of A&P I like most

Gas turbine theory, fuel metering, lubrication, ignition and engine instruments. After I’m certified I’d like to work on engines.

Carried forward from IT

17 years of enterprise infrastructure

The specific tools don’t transfer, but the habits do: troubleshoot one step at a time, write down what you did, and don’t sign off on anything you haven’t checked.

Personal

From Ogle to Orlando: Why I Chose Aviation After 17 Years in IT

Why I left a 17-year IT career for A&P school, and how growing up next to an airport in Guyana had a lot to do with it.

Technical

What Running Servers Taught Me About Aircraft Systems

Redundancy, fault isolation and avoiding single points of failure. A few ideas from IT that carry over to aircraft maintenance.

Technology

The Eight Authors Behind Modern AI

In 2017, eight researchers published “Attention Is All You Need,” the paper that introduced the Transformer. A short look at who they were and what the paper changed.

About me

I grew up in Guyana, not far from Ogle Airport, and spent a lot of time watching planes come and go. I always wanted to know how they worked.

I ended up in IT instead and stayed for 17 years, mostly in infrastructure: Proxmox, FortiGate firewalls, ZFS storage and enterprise networks.

Now I’m a full-time Airframe & Powerplant student at the Aviation Institute of Maintenance in Orlando, focusing on turbine engines. Once I’m certified I’d like to do MRO work for a major airline.

A lot of what I learned in IT still applies. Troubleshooting is troubleshooting, whether it’s a network or an engine.
