The Minimum Equipment List

Building your entry-level A&P tool set


You may think this article unusually optimistic, considering the current economic environment. However, we can rest assured that, unless technology makes a huge leap to instant transporter devices, we will continue using airplanes to move lots of people and cargo. In the past 20 years air travel grew around 4.8 percent per year. During those 20 years we had a variety of financial crises, major world recessions, escalating fuel prices, and a host of conflicts around the world. The growth for the next 20 years is predicted to be about 5 percent. Further, as of 2007 there were about 19,000 main line and regional jets in service, and if projections hold, there will be around 36,000 by 2027. So, optimistic? Sure, but we can all use a little sunshine right now.

Here is the challenge for the new guys and gals. With the projected growth over the next 20 years, there will always be a given distribution of mechanics entering and exiting the work force. The challenge for entry-level A&Ps is that they have to buy tools to perform their jobs. This has always struck me as an upside down process because entry-level A&Ps have to purchase their required tools with their equally entry-level wages. I hadn’t bought tools in a while, and recently found out how unbelievably expensive hand tools are. Last Christmas I bought a stubby 3/8-inch drive ratchet and paid way north of $75. While staring at my receipt, I was reminded of the costs that entry-level A&Ps incur to properly equip themselves. The process seems backwards because sometimes they have to go into debt to meet their job requirements. This started me thinking about how to help entry-level A&Ps build their minimum tools list without breaking the bank.

Buy what you need when you need it
The following are some general tool buying guidelines that will work in a variety of aviation work environments.

1. Start slow and be frugal. Buy only what you need to do your job. The place you work, your specialty, and the type(s) of aircraft that you maintain determine the tools you need.
2. Ask questions and take the advice of your peers before you purchase. You can get tool lists from A&P schools, employers, the union hall, and from reliable vendor representatives. Take advantage of assistance offered by vendor discounts and payroll deduction purchase plans.
3. After talking to other A&Ps and looking at required or recommended tool lists, you have to develop a purchasing plan. Some new mechanics start at Sears, and buy a big shiny roll-away and a general mechanics tool set and call it done. The best rule is to buy what you need and the best you can afford. Always buy quality tools that are backed by a good guarantee. Use your tools safely and always replace worn or broken tools.

Hope this helps. Always treat your tools with care and respect, because they represent you and your profession.

I am sorry to say, but I haven’t found that perfect tool list. But what I can offer is a general tool list that can help get you started. It is organized by category or specialty that has served A&P mechanics in a variety of work environments. It is based on experience and the opinions from those of us who have “been there and done that.”
