I bought the small, red (for emergency), duffle-bag from TIC170A and keep all my emer. supplies in it crammed beneath/behind the rear seat. Here's what's inside.
1. tailwheel tire/tube
2. foot-operated air pump.
3. tire gauge
4. tube patch-kit
5. socket set (this is very complete but >$5 from Walmart in a flat plastic case)
6. 8" adjustable wrench
6a. set of 3 double-ended wrenches (6 sizes 3/8-3/4)
6b. set of two pliers, one channel-lock, one needle-nose with wire cutter (doubles as safety-wire pliers)
6c. Zip-lok bag of assortment of AN bolts/nuts, PK/MS screws. not a lot, only a few.
7. multi-tip screwdriver
8. small 24" coil of .032 safety wire
9. small 24" coil of 14 ga. aircraft elect. wire
10. roll of electrical tape
11. duct tape
12. space blanket (2)
13. hatchet (doubles as hammer/mallet for tie-down stakes)
14. 50' of 3/8 twisted nylon rope
15. bottled water (4@10oz.)
16. MRE's (4) (Meals, Ready to Eat, available from Surplus stores)
17. First Aid Kit (which includes long, H.D. tweezers, scissors, pick, Boy Scout metal-mirror, anti-biotic, analgesic, scalpel, bandages, water-purification, antibiotic hand-soap, insect repellent).
18. kitchen matches in waterproof container (plastic film canister will also work)
19. Military mess kit (makes a small, flat storage container for many of the above small items, plus some salt/pepper/catsup/hot-sauce/mustard/mayo/soy-sauce from the local fast-food chain kept in a ziplok, and can be used for emer. cooking/water-boiling.)
20. Whistle and cigarette-pack size of 5 self-launching marine flares (each about like a short felt-tip marker with a 1000' altitude range) These latter also will light even damp fire-start materials. (So will any left-over aircraft fuel, and the engine oil and spare tire will make very visible fire-smoke.)
21. Cheap, hooded rain-ponchos (2) in pocket-sized pkg.
The above item(s) weighs 22.5 lbs. I don't carry this bag with me on local out-and-back trips, ...only on long cross-country's.
Also, beneath the pax-side rear seat (within reach from the pilot's seat) I carry a new roll of paper towels and 2 qts of engine oil, portable Nav/Com (mine is a KX99), multi-tool, spare flashlight (I have one of the palm-sized rechargeables plugged into my cigar lighter for general and nav. use) with these small items stored within a fanny pack (useful for hiking) along with two of the cigarette-pkg sized family-band walkie-talkie radios. (useful at fly-ins.), and spare batteries. These items weigh an addt'l 7 lbs.
My glove box has 1 ea. spare nav lamp bulb (wingtip/tail), spare interior lamp bulb. And my back seat has 2 small pillows and a liberated airline blanket or two.
When flying in the rugged areas, I also carry a short-barreled cheap ($79 new, but mine is a $35 used Sears/Iver Johnson) shotgun beneath the rear seat. It is a single-shot, barrel sawed to 18 1/4" (the extra 1/4" is in case the cops have a short measuring tape) along with a butt-stock, spare-ammo storage sock containing a couple each 12 ga. slugs, buckshot, birdshot. (I once hid it beneath the sand behind an old out-bldg, prior to a short hop across the border. I dug it up when I got back, cleaned it, and it's still doing fine. It's so cheap, no one even tries to steal it, and even if they did I won't have lost much.) The aircraft compass can be removed for travel using sectional charts, if necessary. (Make certain to leave a note in the window for rescuers indicating your plans and direction of travel if you depart the scene. You
do have paper and pencil in your glove box, don't you?)
An umbrella-tent and my tie-down stakes are all that's necessary to add when deliberately camping.
This list looks big, but it only appears that way. It only takes up space that goes unused in my plane anyway, and although I've never needed to use the stuff, I've loaned some of it out from time to time. (Perhaps those who are prepared don't ever suffer the problems? At least not the ones they prepared for.

) The guys up in Canada/Alaska are probably much better prepared to deal with the realities of being forced down. That's not really my goal with this kit. My goal is to be comfortably reassured when I suffer a minor mechanical failure on a trip, and when a pax/family member says "Honey...do we have any Tylenol?" (etc.) It makes for a much happier travelling companion who's much more willing to go to the far-out places.
