Avoid?

[MTpilot]

"Avoid slip with flaps extended" This is placarded by the flap handle in the 172's that I fly does that mean slips are prohibited with flaps down or just a bad idea. POH doesn't give more detail.

 

[FN FAL]

Try doing a search of the NTSB database and see if you can find an accident or an incident where a high wing cessna crashed while in a slip with flaps down.

 

[qmaster3]

and report back to us..ASAP

 

[User546]

I had an examiner ask me this exact question on my CFI checkride...

So lets here an answer MT!

I'm still alive..

Try taking off with an ICE CUBE in your gascolator and call me in the morning!

I used flaps in the search data field...the NTSB set up is so clunky...anything with the word flaps comes back in the search. Too bad you couldn't just search causal factors.

 

[DGdaPilot]

I've never researched this, but I've always felt that if I'm in an emergency situation, I'm gonna use it (let's say it looks like I'm gonna overshoot a spot I picked after an engine failure). With that, I understand and accept the risks of a tail stall.

 

[MTpilot]

NTSB search too hard!

I couldn't get any results from the NTSB, just a bunch of junk.

I'm sure cessna's have been crashed in all sorts of configurations though

 

[Mmmmmm Burritos]

It'll disrupt the airflow over the elevator with the right angle of attack and slip angle. I've never had it happen on a 172 but a 150 will do it pretty easily. Basically the elevator will start to flutter with the disrupted airflow over it, meaning the yoke will move back and forth on it's own. I quickly got out of that. If there's one thing you don't want to mess with it's experimenting on how to make primary flight controls not function normally.

Gotta love Cessna flaps though, especially the 40 degree ones.

I always love teaching students in the mighty Cutlass. Put in 20 degrees of flaps too soon and you're gonna come way short on making that emergency landing. You can do some neat short field landings with full flaps and full nose up trim on those (fighting the yoke pressure with your hands and not stalling it, obviously). Can anyone say Helicopter?

Well that's scary...

Maybe they just want pilots to "Avoid Slips" period...

CHI04CA239
On August 22, 2004, at 0830 central daylight time, a Cessna 150H, N23316, sustained substantial damage when it landed hard and subsequently departed the end of runway 9 (2,325 feet by 100 feet, concrete) at the privately owned Table Rock Airport (MO32), Golden, Missouri. The private pilot was not injured. The 14 CFR Part 91 personal flight departed Monett Municipal Airport (M58), Monett, Missouri, at an unknown time. Visual meteorological conditions prevailed. No flight plan was filed.

The pilot reported that he did one touch and go at the Turkey Mountain Estates Airport (MO00), Shell Knob, Missouri, and then proceeded to MO32 where he intended to practice landings prior to returning to M58. He reported that the airplane was high on final approach to runway 9 at MO32 so he slipped the airplane to lose altitude. He landed beyond the first one-third of the runway because some grass was growing on the first one-third of the runway. He reported, "The aircraft touched down hard and bounced." He increased power and then reduced it to land. Upon landing he applied brakes but the airplane departed the end of the runway. The airplane struck some truck tires positioned at the end of the runway that act as an artificial barrier. He reported that the airplane did not have a mechanical malfunction prior to the accident.

I think the Gunney R. Lee Ermy would have to ask, "What is your major malfunction Numbnuts?"

And we have a winner !

Excerpt from the above accident report - let this be a reminder that accidents can happen to anyone no matter how many hours or experience you got!

"According to Federal Aviation Administration (FAA) records, the flight instructor held an airline transport pilot certificate with multiple ratings including airplane single-engine-land. On his last FAA first-class medical certificate, dated January 31, 2005, he reported a total flight experience of 26,700 flight hours."

Remember that old WAR tune..."Slipping into darkness"?I'm begining to think there is a conspiracy here...slipping and bending. Whazzup wit dat?

 

[r1830]

I worked at a maintenance hanger in 1998 at Centennial Airport in Colorado. Someone had slipped a 172 with flaps down and over stressed the flaps wrinkling them. The right flapwas damaged more than the left one. Then they tried to retract the bent flaps and damaged the whole flap system as well as created an asymmetric flap condition.

 

[FN FAL]

He slipped the airplane to lose altitude, and put down 40 degrees of flaps. He said the airplane floated, and subsequently landed long. He "went off [the] end of the runway, bounced across uneven ground, and hit trees w/right wing." He said the right wing and fuselage were bent, and the engine's fire wall was wrinkled.More slipping and bending and flaps too!

 

[FN FAL]

Slipping and Brake Horse Power, could not prevent "Crack up"! Film at Eleven!On July 23, 2004, at 1845 Pacific daylight time, a Cessna 172D, N2527Y sustained substantial damage when it overran the runway and struck a fence during landing at Strom Field Airport in Morton, Washington. The private pilot, the sole occupant, was not injured. The airplane was registered to and operated by the pilot. Visual meteorological conditions prevailed, and no flight plan was filed for the Title 14 CFR Part 91 personal cross country flight that departed Everett, Washington at 1800.

As much as I seem to be playing the jerky boy...I do realize that I could be sitting here typing and take my last takeoff tomorrow. "Ask not for whom the bell tolls..."

"This is your "left" CFI speaking...hello ladies and gentlemen, if you'll look out your windows, you'll notice a fence post..."

"This is your "right" CFI speaking, FOUR MORE YEARS OF BUSH!"

"No...fence post!"

"No...BUSH!"

CLUNK!!!

"Uhhhhh...your plane!"

Both pilots stated that the CFI in the left seat took control of the airplane in order to position and park it. The pilot in control of the airplane at the time of the accident, CFI- left, stated, "while pushing the left rudder, [his] foot slipped down and off the

pedal." He stated that he then immediately "pushed full left rudder, but the right wing... hit one of the corner metal poles." The pilot not in control of the airplane at the time of the accident, CFI-right, stated that as the pilot in control "was beginning to set-up the aircraft's turn, his foot immediately slipped off of the rudder. This caused the aircraft's wing to hit a fence pole."​

Hehehehehe... "Beaver Falls" ...somebody please shoot me!

 

[FN FAL]

The pilot stated the accident could have been prevented if he had performed a go-around. If we could use the sight of the hind during our medicals, we'd all have 20/20 vision.

 

[FN FAL]

The pilot reported he flew a Hobbs time of 3.7 hours during the trip. Soy Beans...the other white fuel.

 

[FN FAL]

According to the CFI, the private pilot was practicing short field landings, soft field landings, and slips during the flight. "After his third landing he (private pilot) was instructed to perform a forward slip (power off) landing. He was performing the maneuver with no instructional assistance require[d], when his approach became low." The CFI reported adding power but stated that the airplane was too low and it impacted a threshold light on runway 18. Threshold light...less filling, tastes great!

Boy, I remember when that one happened.

On May 27, 2003, about 1215 eastern daylight time, a Cessna 120, N76494, registered to a private individual, nosed over during the landing roll at Plant City Municipal Airport, Plant City, Florida. Sounds more like "Face Plant City" to me!

 

[FN FAL]

In case you're wondering what I am doing, I'm just basically going through the NTSB files recent to older after doing a search on their website using the word "slips" as search parameter.

Since this file was in sequence and has fatalities, I'm not making any jokes...but you do have to ask yourself "WTF?" on this one. Pretty strange and sad to see.

On January 18, 2003, about 1225 eastern standard time, a Cessna 172P, N65906, registered to Central Florida Air Maintenance, Inc., and operated by Comair Aviation Academy, Inc., as a 14 CFR Part 91 personal flight, crashed near Edgewater, Florida. Visual meteorological conditions prevailed at the time and a company flight plan was filed. The airplane was destroyed and the commercial-rated pilot and three passengers received fatal injuries. The flight originated from Sanford, Florida, the same day, about 1203.

 

[Kream926]

so how come in the 72RG you can do it? All the cfi's i fly with tell me not to be scared of slippin that thing. are they wrong?

 

[DGdaPilot]

no, i wasn't saying to slip with full flaps in a 172RG. It has the same placard as the rest. I just use flaps and trim to bring her down quick.

 

[minitour]

so how come in the 72RG you can do it? All the cfi's i fly with tell me not to be scared of slippin that thing. are they wrong?

Both of ours has a placard to avoid them with flaps extended....

I won't do them, but my CFI sure does...
