Inspection Torch?
Hello,
Long time reader, fist time thread starter.
I'm an apprentice line engineer, and I'm wondering, how bright should my inspection torch be for night shifts, for a general pre flight / post flight, walk around checks?
I've ordered a 154 Lumen torch today, it hasn't been dispatched, so I can still cancel it, I'm just wondering, is that bright enough, or too bright?
The main reason for asking if it is too bright, is, because I have a 45 Lumen head torch I bough today, and that's pretty bright, it clearly light up the top of the 3 story town house I live in.
The torch i bough is the 154 Lumen variant of the Fenix E21.
Regards

Never seen (excuse pun) minimum level lux/lumen/candela of portable hand held ilumination device specified in any aircraft manufacturers document such as the maintenance planning document or AMM etc. However for your fleet it might be. Have a look! Failing that your Employer may have specified it in the QA or other such manual.
Otherwise the Maglite 2/3 cell was the industry standard and most torches of the LED type are more powerful than the Mag.
There are perhaps two more important questions than yours?
1. Can I illuminate all the items specified in the Daily/line check list (eg: The fan OGVs from the back of the fan exhaust for stone or bird damage)
2. Will it work again when you drop it?
Cos you will.

Aha, yeah I cant find anything in our documents specifying anything about a torch.
The guy I was shadowing said its worth investing in a torch that was bright, I cant remember what brightness he had, he said something about a 200 Lumen torch, but I cant remember if it was the one he had, or one that would be too bright.
Yeah, the one i just ordered is safe upto 1.5 meters, but the chances of dropping it from higher are likely.
It'll definitely illuminate areas close, Im just unsure to whether it will be too bright, to the point your eyes hurt trying to focus on it at close range, hiding damage, or if it will be able to illuminate the top of the tail on our current largest aircraft, the 767-300, and the 787-8 (As of next year)

I've recently bought the new rechargable Maglite, pleanty bright enough for a 767 and with a 25% power setting for close up work.
I can also confirm that it WILL survive multiple drops from the tail of a 737NG

I have gone from a 3 d-cell mag, to a rechargable mag, to a stinger over the last 20 years. I now own a 3AAA cell LED headlamp that cost less (made in China) than any previous torch but is just as bright. If you need a hand held rechargable and want to see the upper rudder static wick of a widebody in HD, the Streamlight Stinger LED is a winner.
I find an LED Lenser P7 pretty good, small and portable and light so wont destroy itself or anything else when dropped from, oh I dont know, the top of a fin onto the stab for example.... I have been through about 10 head torches but number 11 has lasted the longest and its called a Gamma bought from a company called Alpkit, its very useful and still beats trying to balance a torch on a bleed duct when you are p!551ng about under a cowling in the dark.

Cheers guys.
When my torch arrives, i'll give it a test, if it turns out too bright at close range, I'll take it back to Maplins and look into the ones you guys suggested.
Unfortunately the torch turns up whilst I'm away from home, so it'll be a while before I can test it...I hate waiting...

The Fenix e21 looks like it will suit you fine. From the specs I read, it has a 48 Lumen output mode as well as the 154. So using it close up shouldn't be a problem.
I've been partial to Streamlights for the last ten years, used on 737 and MD-80. Went through the Ultra Stinger, Poly Stinger and Stinger LED. Currently use a ScorpionX (200 Lumens) and a Argo headlamp. The only disadvantage someone may have with them is the batteries are (2)CR123A, although they have other versions that use standard size batteries.

It's good to look at the FAA research on LED lights and difficulty finding cracks. Google "FAA LED Torch cracks blurred" and you should find the document. Therefore it's best to also have a good filament torch in your back pocket for detail crack inspections at critical points.....

If LED's are banned, that must mean when i was told to buy an inspection torch, to not exceed 200 Lumens, I remember being told something about 200 Lumens, but I couldn't remember what.
I do have a mini Mag-Lite, which is an old LED, gives the same output as a filament bulb.
I'll look into non-LED torches, it doesn't hurt to have more than one torch.
Im back out on the Line tomorrow, so i'm not going to be able to test any torch as they Haven't come in the post yet
In terms of aircraft i work on, to make sure it reaches the top of the tail on inspection, I work on; 737Classics, 737NG's, 752, 763, and as of next year, 787-8
Thats my only main concern, will it illuminate the tip of the tail, oh, and that its not to bright at close range it hurts my eyes to focus on it, potentially masking damage.
If any of you more experienced engineers could suggest tooling i should carry on the line, i'd be grateful of a pm. I know the basic tooling i should have, but what would you guys suggest?

All I carry with me on a turn-around is a torch, a #2 phillips screwdriver, a medium flat-blade screwdriver, an allen key set and some adjustable pliers, all carried in a fabric tool roll. You will be able to accomplish 90% of the things you need to do with those few basic items. The rest of my tools I keep in the van downstairs for when they are needed.
A lot of people have Leatherman-type multi tools, I tried that out but found they were not really man enough and it is easier just to carry the proper tool.

I also use a Led Lenser P7 (190 Lumens I think ). Also have a Olight T25 with similar output. great for outside night work but even on low settings they can be a tad bright and white in some situations. But overall great investment.

Read down for Info on light sources. F-C stands for foot candle, an old standard that used to cause trouser fires
