Anyone Spin a 172S?

[Steve]

Anyone spin a 172S? Anything special about it over the N models?

 

[Mmmmmm Burritos]

Uh, no. A new engine and new instrument panel do not noticeably change spin characteristics. The controls probably aren't as loose though in the S.

Embry-Riddle had a 172S they used for spins when I was there. Nothing different that I (an average pilot) can notice.

Ive done them in both S and R's and they scared the pi$$ out of me in both.

I've spun 172s lots (spin training is part of the licence in Canada, tho not as much as it used to be), but it's been so long that I don't know what model. What are the differences amongst S, R and N (are there any more model no.s)? Isn't a 172 pretty much a 172 is a 172?

So once I had this student and we went up and at the end of the lesson I got a long lecture on NOT touching the controls. (And no, I was not one of those instructors that flew the whole lesson)



So on our next lesson (in a 172) he shows a power off stall with flaps. A wing drops, he promptly applies opposite aileron, the nose drops, he yanks back on the yoke and now we are wound up in a pretty good spin. So I say… well since I’m not supposed to touch the controls (insert screams) you should set the flaps to zero (more screams) apply rudder opposite our direction of rotation and press forward on the yoke (more of a homer simpson yelp now)



That was our last lesson.

YES!!!! There is a noticeable difference in the way they both spin. I've spun both models several times while instructing CFI students.

The new Cessnas have a heavier engine and larger fuel tanks. I don't know for sure, but I've always suspected that the fuel tanks are a little bit further out into the wings than the old models. Because of these changes, the new 172 will enter a COMPLETELY DEVELOPED spin. Translation= after about 1 1/2 turns, you can take your hands and feet off the controls, and the plane will continue to spin. When it gets to about 3 turns, it will go flat and scare the piss out of you if your use to spinning the old models.

The old model Cessnas would never completely develop. They use to spiral out of the spin, even if you entered cross controlled and held it that way.

The short:
The new model has weight that is further away from its center, and probably tighter control cables. Because of this, it will develop easier and spin tighter than what you would expect if you've only flown the old models.

Hey!...is this true? Fantastic!...Now maybe the spin training will have some teeth.

I've always had to FORCE these Cessnas to spin. You know - FULL HARD RUDDER AND ELEVATOR AND HOLD IT HARD. Otherwise it comes out of the spin or never develops into a spin. That's lousy training. Students get the idea that it won't spin unless forced - which is true in Cessnas (most Cessnas) but it sets up a bad habit pattern for some other types.

We need a training airplane that will enter a fully developed spin you can take your hands off of and it will continue to spin until FORCED OUT of the spin - not FORCED INTO. Duh!

I wouldnt do it, read THIS!

[font=Arial,Helvetica]Emergency AD Affects New 172s, 182s[/font]

If you've recently taken delivery of a new Cessna 172 or 182, check the serial number against a list in an Emergency Airworthiness Directive issued Friday. A few dozen of the brand-new airplanes are grounded until they can be inspected for potential control rigging problems. "The FAA has been notified that inadequate or incorrect flight controls rigging may exist on recently produced Cessna Models 172R, 172S, 182T and T182T," the Emergency AD reads. It should be stressed that the affected airplanes are grounded. No ferry permits or repositioning flights will be allowed. Cessna staff discovered various problems with aircraft still in the factory. However, it's believed that some potentially flawed airplanes were delivered (i.e., flown) to their new owners, who, presumably, have also been flying them.

​

[font=arial,helvetica,geneva]...Long List Of Defects[/font]

What's perhaps most disturbing about this AD is the breadth of defects discovered by Cessna technicians. Normally an AD focuses on a specific part or system in an airplane but this one identifies a Pandora's box of potentially serious issues. According to the AD, Cessna found misrigged and misaligned control surfaces, a missing bolt on a flap push/pull rod, cables chafing fuel lines (resulting in damaged fuel lines), cables routed outside cotter pins, crossed cables, cables routed outside of pulleys, cables rubbing on bulkheads and center consoles, unpinned or improperly pinned barrels on control cables and a bent flap bell crank. These are new aircraft, remember. The AD calls for an immediate, detailed one-time inspection of the flight control system and repairs, as necessary, to bring the system up to standard. Since the AD prohibits any flights before compliance, those with aircraft in places without suitable maintenance facilities are advised to phone Cessna Product Support .

Haha! A while back, I got hired at a new flight school as an instructor. Well, I had to be checked out in the 152 with the Chief Instructor. So off we go. Now, I hadn't flown a 152 in ages, but everything went fine. I demonstrated a power on stall at the Chiefs command and wing dropped a little bit. Before I could do anything, the Chief yelled, "I got it!" and frantically grabbed the yoke, threw in complete opposite aileron, and over we went! I quickly realized this was not part of the exercise. I assured the Chief that I had it, applied opposite rudder and recovered, and made a mental note to never fully trust a pilot because they have some sort of fancy title in front of their name.

Wow.

I found older ones to spin a little easier than the new ones (i.e. P and N, models) vs. the new S. The new S, even x-controlled will just go into a high speed spiral, rather than a fully developed spin. The CG seems to be more forward and the nose likes to drop and "self-medicate"
