Yes, right on. It has vertical and horizontal stabilizer surfaces and rudder and elevator control surfaces, and may also support the APU. Construction-wise, the empennage has many closely spaced frames and longerons (stringers) because it acts as one end of a long lever--so the loading forces...

We have to start with the basics before we can discuss the minute. And since the interest in aircraft is almost as popular as thick versus thin oils, we must discuss basic components before discussing details. That falls under Stress and Fatigue Analysis and I have a thrown a bit of that into...

We're going to further discuss engines in a later Q&A and discuss thrust "Augmentation." One also has to take into account the AB temperature, which would affect the lifetime of the AB components and prior burner cans in the hot section. The position of where the fuel is injected and the amount...

What is an Empennage structure, and what does it support? An Empennage structure is also called a tail or tail assembly.

I would also say engine design and what the stoichiometric ratio is at the time of AB initiation.

@Skippy722 "They’re designed to fail after a certain amount of force has been applied to them to prevent greater damage." Yes, break or fail; and thanks for keeping on topic. If the engine were to run out of oil, the spinning components would seize, and a large torque component would result...

The second part of this question is: What is the purpose of Fuse pins and hollow "Fuse" bolts?

Yes, American Airlines Flight 191, a McDonnell-Douglas DC-10-10, crashed on takeoff from Chicago-O'Hare International Airport, Illinois, USA. This was due to improper mounting of engines with a forklift. "On the accident flight, during the takeoff rotation, the number-one engine and its pylon...

The first diagram, the general one, is that of a DC-10 wing-mounted pylon. The second one below is a generic pylon showing some internal structures.

(y) The Pylon, also called an engine mount, is a structure positioned between the engine and the wing or fuselage. It is designed to not only carry the dead weight of the engine, but also torque and engine thrust, both forward and reverse. The pylon attaches to the engine "case" via two or...

On most commercial aircraft, the engine is external and attached to the wing or fuselage. What is the name of the structure that attaches the engine to the wing or fuselage?

2.7 gave an overall description, and Boomer gave us rigidity—all good. Frames are like ribs in that they help to maintain shape, in this case, the shape of fuselage barrel. Stringers or Longerons run through or along the frames and are bonded to the frames. The curved Frames, usually of a...

No. What you see in a TDS is a listing of the Oil Properties. See the Bitog Glossary: https://bobistheoilguy.com/glossary/

None. What you see in a TDS is a listing of the Oil Properties.

FWIW, I have the older 4.0L version and use 5w30 in the winter and 10W30 in the summer.

@Cooling617 "I recently had a oil change at a local shop and I supplied a new Fram oil filter - part # Xxxx. I confirmed it was the correct filter..." So you supplied the filter. I seriously doubt the filter caused any engine damage.

What is a Frame and what is its function in a fuselage barrel? See Cujets picture below of a fuselage structure.

We're going to get to frames shortly. @Cujet Thanks to Cujet for the great pics and the background info. In a fuselage barrel, the Longerons or Stringers carry the "longitudinal" loads, such as the twisting and bending loads encountered in all phases of flight. The spacing of the stringers...

We're going to try a Q&A on aircraft structures that comprise various parts of an aircraft since Aviation and aircraft in general is a popular topic. Our first question is, "What is a Stringer (also called a longeron), and what is its function for an aircraft fuselage barrel? Some of the...

You're kidding, right? Crossing insulated wires has nothing to do with it. It appears you need cables anyway, so get a set with slightly longer cables; problem solved.
