AOPA Air Safety Institute: More Difficult Decisions

Unusual Attitude Recoveries

ByHank Gibson April 10, 2018April 24, 2018

For a VFR or an IFR pilot, an unusual attitude can be one of the most dangerous situations to get into.  That is one reason so many new autopilots are being developed with a level button.  The concept behind the level button is if the pilot gets into a disorienting situation, press the level button and the autopilot comes on, holding the airplane in a straight and level pitch attitude.

What about all those planes without autopilots that have a level button?  That’s who this article is for.

First off, what is an unusual attitude?  The Airplane Flying Handbook on page 4-17 gives the following definition:  “An unusual attitude is commonly referenced as an unintended or unexpected attitude in instrument flight.”  The AFH also goes on to say that an unusual attitude in training has no defined bank and pitch parameters, but “for training purposes an instructor could place the airplane in a 30 degree bank with a nose up pitch attitude of 15 degrees and ask the student to recover and that would be considered an unusual attitude….”

We now have a basis from the FAA.  VFR Pilots are now saying, “Oh, instrument flight, that doesn’t apply to us.”  Not so fast.  The Private Pilot ACS (and before it, the PTS) has a requirement for Basic Attitude Instrument Flying, including unusual attitude recoveries.  Why?  Because VFR pilots still inadvertently fly into IMC conditions and can get into an unusual attitude.  Plus, a private, non-instrument rated pilot has a higher chance of not recovering from an unusual attitude since he isn’t used to relying on his instruments.

At each training event I do, whether it be private pilot training, a flight review, IFR training, transition training, or pretty much any kind of recurrent training, I like to do unusual attitude recoveries with my customers.  It’s one of those things that the recovery procedure wanes over time since it isn’t routinely practiced solo (for good reason!).

I see people have the most trouble with the nose high unusual attitude recoveries.  Let’s start with the recovery procedure, then I’ll discuss the common errors (notice that the nose high unusual attitude recovery procedure mirrors a stall recovery).  Remember, this is in IFR conditions:

• Breathe
• Pitch Down to a level pitch attitude on the Attitude Indicator (or lower if the stall warning horn continues to go off)
• Simultaneously add full power
• Roll wings level
• Flaps up and recover to a level pitch attitude if not there already

The order is important, especially the breathing part.  What happens if a pilot goes straight into a recovery and doesn’t pause for a second or two to absorb what’s going on is the recovery isn’t executed properly.

Our brains see the wings banked and set off all kinds of alarms to roll the wings level first before doing anything else.  Adding any kind of aileron input with the nose close to the critical angle of attack is a bad idea.  You are adding adverse yaw (since you probably won’t be coordinated) and load factor which increases the stall speed.  Then we all know that Stall + Yaw = Spin.  That’s something that is best avoided in IMC.

We have to teach our brains to ignore the bank angle until the pitch and power come in.  Once the airplane is far away from the critical angle of attack, then the bank can be rolled to neutral.

Let’s look at the nose low unusual attitude recovery.  The order is still important on this one too:

• Breathe
• Power Reduce (to idle if necessary)
• Roll Wings Level
• Pitch up to a level pitch attitude
• Add Power back to cruise

The theory with the nose low unusual attitude is your speed is accelerating.  By reducing the power first, that helps reduce the load factor experienced when the pitch is increased.  Same with rolling the wings level.  Neutral bank is a lower load factor than some kind of a bank angle.  We are trying to prevent overspeeding the airplane.  The lower the load factor, the less of a chance we have to rip the wings off.

The most important step in either recovery procedure is to breathe first, allowing the brain to process exactly what is happening.  That way, the proper recovery can be executed.

Beechcraft Flap Issues

ByAndrew Robinson September 8, 2015

There has always been something that felt wrong to me about how the walkway on many models of Beechcraft extends onto the right hand flap. I have never felt right about stepping onto the flap as I make my way into and out of my dad’s E33A Bonanza and therefore I generally try to step over top of it and place my foot on the wing instead. But does this effort actually make any difference, or am I just making my self look silly for no reason?

Well, as it turns out, it wasn’t such a bad idea. In 2007, a pilot flying a Beech reported a split flap condition. Upon inspection, it was found that there was damage to the actuation rod attachment as well as the nose rib and nut plates. Six other aircraft were checked and found to have similar damage. These findings were submitted to Hawker Beechcraft and in 2008 and they issued a maintenance alert regarding the issue. In 2011 the FAA issued SAIB CE-11-21 (Special Airworthiness Information Bulletin) to alert owners, operators, and maintenance personnel about the problem; specifically warning of the potential for cracking in the nose flap rib (part number 35-165050-84). And while its true that this type of damage is not limited to the right hand flap, it is known to be much more common on that side. Stepping over the flap instead of on it is recommended by both the FAA and Beechcraft as a solution.

Unfortunately, the flap cracking is known to span a wide variety of aircraft types. A 2011 “Safety Communique” issued by Hawker Beechcraft lists the affected models as:

-Bonanza 33, 35, and 36
-Baron 55, 56, 58, and 95
-Duke 60

According the the FAA, the cracking can been found most commonly on airframes which are between 4,000 and 6,500 hours, but has also been found on aircraft with as few as 2,000.

So, what do we do about it?

First off, although much of the damage is difficult to detect without dis-assembly, the paperwork from both the FAA and Beechcraft recommend taking a look at the flap yourself to see if there are any obvious signs of problems. They also suggest taking special care looking in this area during your preflight inspections.

Next, if you have an airplane which may be susceptible to cracking, talk to who ever is doing your maintenance work and have them look carefully during your annual inspections. I talked to one of the IA’s at our shop who has dealt with this issue before and he told me that most shops will remove the flap and send it away to a repair station to have it fixed. It’s possible that if you purchased your airplane used it may have already had this issue taken care of; a quick look through the maintenance logbooks should clear up any questions.

Regardless of whether your airplane is known to suffer from this problem or not, do your best to avoid stepping on the flap when getting in and out of the cockpit. It is also a good idea to ask your passengers to do the same as this simple act could end up saving you big headaches and big money someday down the road.

Aircraft Purchase: The Logbook & Pre-Purchase Inspections

ByHank Gibson July 10, 2014July 14, 2026

Your about to make your dream aircraft purchase.  The plane has low time on the engine, is reasonably priced, and, according to the seller, has no damage history.  You are overjoyed!  Your dream of making an aircraft purchase is finally coming true.  You prepare your offer for the seller, set up the escrow account, and start all the paperwork.

Two weeks later, the airplane is yours!  You start flying it, though, and the engine starts to have some strange vibrations.  After several flights, it starts to get worse.  You take it to your mechanic to get it looked at and you find out the airplane needs three new cylinders along with some other engine work that is going to total a lot of money.  Plus, your airplane is now going to be in the shop for several weeks.

All that excitement you just had?  It just went out the window.

Could this have been prevented?  Probably so, with a logbook inspection and a pre-purchase inspection.

Aircraft Purchase: Logbook Inspection

Inspecting a logbook can be very daunting when making an aircraft purchase, especially for older airplanes.  This is, however, one of the most vital steps in making a new aircraft purchase.  You can find out many things from looking at the maintenance logs of an airplane.  First, you can check the compression levels of the engine.  Typically, you want compression levels in the 70’s, with it still being okay in the high 60’s.  Anything below 65 and there could be potential problems.

Second, you can find out if there has been any odd maintenance done pointing to possible unreported damage history.  This is rare, as most aircraft owners are honest and up front when talking about damage history.  But, if there is an entry detailing a prop overhaul after only 50 hours on that prop, you may start to ask some questions.

Third, you can find out how well the airplane has been maintained.  If a lot of maintenance was completed at each annual, even if it was a lot of small things, then the airplane has been maintained by a good mechanic who is very thorough.  This also involves a check of the ADs, Mandatory SBs, SBs, and SLs that have been issued for the airplane.  If all that has been kept up with, it’s a well maintained airplane.

Finally, it gives you a good idea of how much the airplane has been flown.  Sure, the ad online will have the total time and time since overhaul, but you can look at the year by year breakdown of how much the airplane has been flown.  It may have been flown a lot earlier in it’s life, but not quite as much recently.  That’s not necessarily a bad thing, but airplanes like to be flown.

Aircraft Purchase: Pre-Purchase Inspection

Before making an aircraft purchase, it is extremely vital that whenever you are buying an airplane that you get a pre-purchase inspection done on the airplane.  Even better is getting one done by a mechanic who specializes in that type of airplane (eg. Piper Service Center for Pipers, Cirrus Service Centers for Cirrus, Kevin Mead for PA-46s).  A pre-purchase inspection can save you a lot of money in the end.

There is always going to be some kind of maintenance issue with an airplane being purchased, whether it is big or small.  Once a pre-purchase inspection is completed, you can take the findings to the seller and negotiate for a lower price based on those findings, or just have the seller fix the items before the sale is completed.

I would recommend having the seller fix the problems before the sale is completed.  Even though it may take a little longer for the sale to be completed this way, you’ll get to enjoy your airplane right away instead of it being in the shop the next several weeks after you complete the purchase.

There is the circumstance where the  pre-purchase inspection reveals some serious airworthiness issues which would cause the deal to be voided.  Always put this clause in a purchase agreement, giving you, the buyer, an out if there are serious airworthiness issues.

When it comes to making an aircraft purchase, it is not a process to be rushed.  Slow and steady usually gets the best airplane for the money, giving you years of enjoyment in the future.

Looking to make an aircraft purchase?  Daunted by all the work that’s involved to find a good, quality airplane?  Let Texas Top Aviation do your aircraft search for you!  To learn more, visit Texas Top Aviation’s Aircraft Purchase Consultations page.

Mooney Enters the Training Market with the Mooney M10

ByHank Gibson November 19, 2014December 5, 2014

Earlier this week, Mooney announced they would be following competitors Piper (with their Archer DX) and Redbird (with their retrofitted 172 known as the Redhawk) into the training market with the Mooney M10 T and Mooney M10 J.  Mooney, which hasn’t manufactured a primary trainer since the Mooney M10 Cadet in 1970, is planning on putting Jet A burning Continental Engines in the new aircraft.  The mockup was unveiled at Airshow China.

The Mooney M10 T is a 3 seat, fixed gear trainer sporting a Continental CD-135 engine.  At 135 HP, the initial design data claims the Mooney M10 T will be able to cruise at 140 KTAS at 75% power, allowing the Jet A engine to burn between 4-5 gallons per hour while holding 42 gallons of fuel.  As with other Jet A piston powered airplanes, the Mooney M10 T will have a Fully Automated Digital Engine Control (or FADEC) system.  This leaves just a single power lever in the cockpit, allowing the pilot to set a percent power and the FADEC computer will set the manifold pressure, prop speed, and mixture.

The Mooney M10 J has a slightly bigger engine, the 155 HP Continental CD-155.  It also is equipped with retractable gear.  Initially, Mooney is predicting 160 KTAS at 75% power for the Mooney  M10 J.  The airplane will come as a two-seater, but will have a third seat as an option.  Mooney says that the Mooney M10 J will allow pilots to make an easy transition to the bigger and faster M20J that has been popular for many years amongst “Mooniacs.”

In a new direction for Mooney, the Mooney M10 T Mooney M10 J will both be composite airplanes with side sticks, instead of the traditional sheet metal exterior with a yoke as Mooney aircraft have been in the past. Also venturing from the more powerful Mooney aircraft is the fact that the Mooney M10 T and Mooney M10 J will have two doors.  Remaining, though, is the swept tail that Mooney aircraft are known for.  Both airplanes will be equipped with Garmin G1000 panels, while the Mooney M10 J will also have the GFC 700 autopilot, marketing more toward aircraft owners rather than students.

The only downside that I read about was the time between replacements for the engines.  For the CD-135 engine in the Mooney M10 T, time between replacement is 1,500 hours, whereas the CD-155 only has a 1,200 hour replacement time.

Mooney expects certification and deliveries to begin for the Mooney M10 T and Mooney M10 J in 2017.
