This does not paint a good Maintenance picture are all birds put through the same Depot level service (same place?)? Are service intervals and details different from one branch of Service to another or the Aircraft's actual assigned task?

That's pretty horrible. Another KC-130 crashed near Japan a few days ago. It can be a dangerous business.
Wasn't it yesterday? The refueling mishap off Hiroshima?Quote:

Jeez, that's terrible. Looks like it was nearly instantaneous from the first prop blade breaking off until the flight deck was separated from the rest of the aircraft.
I'm surprised and a bit impressed that the rearward section of the plane was rather intact in the field.
I saw the report several months ago. Sent shivers down my spine.
I can't speak for other services maintenance schedules, but ours go through regular depot maint at a couple different places.
The Hurk that went down a couple nights ago off the coast of Japan refueling a FA-18 was a KC-130J.
Maybe it is time for a retirement. The design has been flying since 1954. Surely we have something safer?
I was going to say, I'm surprised a J model would already have enough wear for something to happen. But reading the news, this was a mid-air collision with one of the Hornets??Quote:

So one blade of a propeller cuts loose and slices into the air frame. A moment later a complete propeller assembly cuts loose and slices into the air frame opposite the first intrusion.
Effectively the air frame, within a fraction of a second, is decapitated. I can understand the micro-fractures causing the blade to cut loose.
I don't understand how an entire propeller can cut loose. I'm not familiar with the mechanical assembly connecting the propeller to the engine.
It sounds like it was just shear failure, that thrown prop blade just tossed around the plane so sharply that it overstressed the prop hub on the other side, and then the fuselage buckled.
Instantaneous in this case is a relative term, as perfectly balanced as propellers are, I would imagine the vibration of one missing a blade would send all kinds of instantaneous effects across the entire airframe causing a domino effect of catastrophic damage.Quote:

If the disintegrating propeller, cuts the control lines, catastrophic failure can occur.
Just my 2 cents.
"Each engine is equipped with a Hamilton Standard, four-blade, electro-hydromatic, full-feathering, reversible-pitch propeller. The propeller operates as a controllable-pitch propeller for throttle settings below flight idle and as a constant-speed propeller for throttle settings of flight idle or above. The major components of the propeller system are the propeller assembly, the synchrophasing system, the control system, and the anti-icing and deicing system"

It didn't cut the control lines, it cut into the longeron, a structural assembly that goes along the length of the aircraft fuselage. Essentially, these props cut the plane's spine.
I've described it similarly but substituted keel instead of spine using naval terms on how a ship can break its back.Quote:

That's a good way to describe it. Once the forward portion of the fuselage separated, control lines meant nothing.Quote:

Hoser has been a crew member for some time. What his actual duties are I will leave to him.Quote:

The propeller shaft must have sheared for the propeller assembly to break loose. That is an amazing amount of force.Quote:

Prayers to the lost and their families. So sad.
Amazing airplane design with an outstanding record. Always wondered if those red propeller stripes on the fuselage were copied on the inside.
No, but I have one fewer landings than takeoffs in a C-130.Quote:
