I'm a licensed Aircraft Mechanic & Inspector with twenty five-plus years in the field. I've had a varied career so far, with time spent in the sheetmetal, mechanic, and inspection specialties. Most of my time is on heavy Boeing and McDonnell Douglas aircraft, of the passenger, cargo, and experimental type. This career isn't for everyone, but I enjoy it.

Please do NOT ask me to troubleshoot problems with your airplane, that is not what this Q&A is for.

How big of a divot to a plane's exterior would change its aerodynamics? If I took a hammer and just whacked the top of the wing a few times to dent it slightly, would that render the plane non-airworthy?

Asked by wutang over 11 years ago

Strictly speaking; I don't know.  If you look in the maintenance manual for any given aircraft, you will find limits for dents.  Depth, width, etc.  These would be dents that do not have any structural damage of any other kind associated with them.

So, if you took a hammer and dented the airplane 'slightly' it may or may not be airworthy.

Would it fly?  Probably; because it would take a terrific amount of surface deformation to ruin the aerodynamics completely.

But technically airworthy, is another matter.

I am a brand new A&P. What advice would you give to someone like myself, especially in regards to improving my skills? I came into school with virtually no mechanical experience, so the last 2 years were a growing process for me.

Asked by Nate about 8 years ago

One word: Diversify.

For your long term career health, try to diversify as much as possible in these beginning years of your A&P career.  

You will probably get stuck in one department or another, if you work for a large outfit, and that's fine. Learn all you can, and try to be the best you can be (learn the manuals and how to find what you need in them!). But whenever you can, take the opportunity to work outside of your department specialty. Lend a hand to Avionics, Sheetmetal, Composite, Powerplants; whenever you can. An extra hand that knows how to do things will seldom be turned away when it is needed. 

"Help me...... buck this rivet, ring out this wire, hold this bolt while I torque the nut, get the vacuum set on this composite repair...." All things that help you learn a little bit more.

Eventually, you'll probably settle into one speciality; maybe start moving up the ladder; and that will make it harder to do other things. So do it now, while you are new. It will pay off in the long run, when you want to try being an inspector, or a manager, or a maintenance planner. Experience helps you make better decisions.

If it is hard to branch out at work, then think about any local aviation museums. Places like the Yankee Air Force are always looking for qualified volunteers. You'll learn a ton from the old retired guys that are usually there.

I have some standard advice I give too: Don't go into deep debt with the tool truck (Snap-On, etc); just get a decent box, and decent tools; you can add the fancy stuff later as you need it or can afford it. People might sometimes tease you for having Craftsman tools or the like, but you'll have more money in your bank account. (Except for the Snap-On ratcheting screwdriver, with the hard plastic handle; those cannot be beaten. Well worth the money)

Don't step on too many toes, or piss too many people off needlessly. This industry is smaller than you can imagine. Often you'll have to go back to work for a place you never thought you'd go back to; or work with/for someone from the past who wasn't your favorite person. Just keep it professional when in doubt.

I'm in school currently to become a aircraft mechanic and I have a paper to write and had some ?s. what kinds of reports do u have to make while working? What kinds of oral communication and to whom? types of communication? What happenswith poor com?

Asked by Will over 11 years ago

There are several types of 'reports' that I have to make in the course of my work.  

The simplest one is the Non-Routine.  When I find something wrong, or that needs doing on the aircraft: I fill out this form, which gets recorded in the records, and then is addressed by the appropriate department at our Repair Station (maintenance, sheetmetal, avionics, paint shop.....etc)

Another kind of report we have to fill out sometimes is called an Service Difficulty Report (SDR).  These are filled out whenever certain "critical" systems or structures have a problem.  Such as emergency equipment.  If we have an emergency light that doesn't test properly; we have to fill out the report.  This gets submitted to the FAA, and goes into a huge database which is all sorted out as to types of aircraft and issues; and is used to help them decide when to issue Advisory Directives (AD's).

As to Oral Communication:  There is oral communication all the time.  Even if it is something that is written down, we usually go over it verbally (and use our hands for that matter).  As an Inspector, I communicate with the mechanics on the floor, their supervisors, and often the Hangar or Shop Foreman.  At our Repair Station, everything is 100% inspection buyback; so we are constantly in demand to witness certain steps of jobs, or to do final buyback on tasks.

We use all types of communication here.  We use written communication, via our non-routine and routine task cards, written turn overs on jobs and shift work, as well as little grease pencil notations on the aircraft itself, to help guide mechanics to the discrepancy areas.

We use oral communication, to discuss the steps of a job that is about to be performed, as well in all other steps of maintenance.  Reading body language and speech inflection is also important when talking about the work at hand.

Poor communication results in about what you'd expect.  From the nearly harmless simple repetition of a task that was already completed; to the disastrous of having an aircraft fall off of jacks during a jacking procedure, due to confusion in the communication between the guys manning the jacks and the person monitoring the level indicator.

Essentially, with poor communication; people can get hurt or die, and aircraft can be damaged or destroyed.  

Clear, concise, and timely communication is essential to any operation; especially aviation activities.

Hello Sir,
I'm Naba from India..
I'm 16 years in 10 grade.
I want to become a aircraft mechanical engineer.. So I am planning for my further studies.. Which country/city should I plan to go after I finish my 11th grade?

Asked by Naba nargis over 9 years ago

Naba, as an FAA licensed aircraft mechanic & inspector, who has worked primarily in the Mid-Western USA; I can really only answer you based on that experience.

If you plan on coming to the USA to get your Airframe & Powerplant licenses; I would recommend against large "Mechanic Factories" such as Emery Riddle.  Choose a smaller school program.  My Alma mater is the Lansing Community College aviation technology program, and I liked it very much, and it did not cost too much for a two year degree + my A&P.  I can also recommend the aviation maintenance program up at Northern Michigan University; where you can get your A&P, and stick around for a four year degree as well.  Those would be my personal recommendations.

If you meant going to some other country, then I'm afraid I cannot help you much.  

If you meant becoming an aircraft mechanical engineer, in the respect of being the guy who designs the aircraft; then I'm really really not the guy to give you advice.  I'm a mechanic.  :D

What do you think are the most realistic plane crash movie scenes?

Asked by evan almost 12 years ago

I really can't say. I've never been to a real crash site before. From the pictures I've seen, you usually have one of two scenarios: Either there is nothing but little chunks of metal and debris everywhere, or there are several largish chunks of airplane (sometimes just one bent up airplane if it was really low speed). I do know what isn't very realistic. Having engines running after the crash, is pretty far fetched, such as was seen in the opening scenes of Lost and Cast Away. Maybe I've just avoided most plane crash movies.

As a certified aircraft mechanic, do you travel anywhere in the world for free or do you still have to pay for the plane ticket.??

Asked by Kou Yang over 11 years ago

No, I certainly cannot travel for free anywhere.  I, along with most other mechanics must pay our own way, just like the rest of the public.

Often, if you work for one of the major commercial air carriers, you can get discounts, or fly free on 'standby'.  But, most mechanics do not work for those companies.

How do they install wifi on an airplane? My phone doesn't get reception at 30,000 feet, and don't they need that signal to make it work?

Asked by MOOAAR almost 12 years ago

The system I've seen installed is a satellite based system. A satellite antennae is installed on top of the aircraft, and then a wireless router is located somewhere in the cabin. So no, it doesn't use the same land based signals that your phone uses.
